該事業(yè)的提議引起了國內(nèi)外的廣泛關(guān)注，被公認為近年來在環(huán)境領(lǐng)域影響力和公認的里程碑之一。
道治理用的除磷劑是對城市水源水混凝除濁處理及除磷的物品?？梢栽趯Τ鞘兴此炷凉崽幚硗瑫r，到達深度除磷意圖。
從而將處理后飲用水中的磷含量降至界限值以下，不需要改動原水處理流程，不需要增設(shè)大型水處理構(gòu)筑物，簡便易行，經(jīng)濟實用，可獲得顯著的社會和經(jīng)濟效益。
河道治理用的除磷劑運用方法量投加不會造成不良影響的，畢竟鐵也是微生物生長所需要的微量元素。但是如果投加量過大，則會使污泥活性收到影響，還有疑問可以到環(huán)保.通交流。
生化末端 沒有影響，何況少量的鐵鹽能夠?qū)hosphorus removal agent for road treatment is a kind of material for coagulation and turbidity removal of urban water source and phosphorus removal. It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.
Thus, the phosphorus content in treated drinking water can be reduced to below the threshold value, without changing the original water treatment process, without adding large water treatment structures, which is simple, economical and practical, and can achieve remarkable social and economic benefits.
The amount of phosphorus removal agent used in river regulation will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is too large, the sludge activity will be affected. There are still doubts about environmental protection and communication.
There is no effect on the biochemical end, let alone a small amount of iron salts.
懸浮物上漂
1、操作不當(dāng)，有的是不專業(yè)的人員在實驗中運用了不當(dāng)手法，加入聚合氯化鋁后，攪拌過急過慢都不行，初次實驗，要有專業(yè)的水處理師從旁協(xié)助，這是很重要的一點。
2、加聚合硫酸鐵的量沒有控制好，（加藥過多或過少）這種情況，最容易出現(xiàn)懸浮物上漂。
使用前，將本產(chǎn)品按一定濃度（10-30%）投入溶礬池，注入自來水?dāng)嚢枋怪浞炙猓o置至呈紅棕色液體，再兌水稀釋到所需濃度投加混凝。水廠亦可配成2-5%直接投加，工業(yè)廢水處理直接配 成5-10%投加。 b、投加量的確定，根據(jù)原水性質(zhì)可通過生產(chǎn)調(diào)試或燒杯實驗視礬花形成適量而定，制水廠可以原用的其它藥劑量作為參考，在同等條件下本產(chǎn)品與固體聚合氯化鋁用量大體相當(dāng)，是固體硫酸鋁用量的 1/3-1/4。如果原用的是液體產(chǎn)品，可根據(jù)相應(yīng)藥劑濃度計算酌定。大致按重量比1:3而定。
關(guān)于污水處理使用聚合硫酸鐵上水層出現(xiàn)漂浮物的原因以及解決方法
污水處理1. Improper operation, some non-professional personnel in the experiment used improper techniques, adding polyaluminium chloride, stirring too fast or too slow can not, the first experiment, there must be professional water treatment assistant, this is a very important point.
2. The amount of polyferric sulfate added is not well controlled (too much or too little dosage). In this case, suspended solids are most likely to float.
Before use, the product was put into the alum bath at a certain concentration (10-30%) and stirred with tap water to make it fully hydrolyzed. The product was put into a red-brown liquid and diluted with water until the required concentration was added and coagulated. Waterworks can also be added 2-5% directly, and industrial wastewater treatment can be added 5-10%. B. The determination of dosage depends on the proper amount of alum bed by production debugging or beaker experiment according to the nature of raw water. The other dosage used in water plant can be used as reference. Under the same conditions, the dosage of this product is approximaby equal to that of solid polyaluminium chloride, which is 1/3-1/4 of that of solid aluminium sulfate. If the original liquid product is used, it can be calculated according to the concentration of the corresponding agent. It depends roughly on the weight ratio of 1:3.

3、加聚合硫酸鐵的量對了，但是廢水的PH值不對，沒有在相應(yīng)藥劑的用PH范圍。適應(yīng)水體PH值范圍寬為4-11，PH值范圍為6-9，凈化后原水的PH值與總堿度變化幅度小
4、使用凈水產(chǎn)品的型號不對，根據(jù)污水的特點，選擇適合自己污水特征的凈水劑，如：聚合氯化鋁、聚氯化鋁、聚合氯化鋁鐵、氯化鋁、噴霧式聚合氯化鋁、白色聚合氯化鋁等等，聽從專業(yè)水處理師的指導(dǎo)意見，他們給的意見都是專業(yè)性的。

聚合硫酸鐵
5、最后一點要考慮的就是，你所使用的聚合硫酸鐵，質(zhì)量是否達標(biāo)，聚合硫酸鐵的各項指標(biāo)是否符合標(biāo)準(zhǔn)。
現(xiàn)在市面上聚合硫酸鐵的質(zhì)量參差不齊，相對于質(zhì)量好一些的聚合硫酸鐵在使用過程中，出現(xiàn)懸浮物的幾率會很低的，好一些的聚合硫酸鐵幾乎是沒有水不溶物的，所以產(chǎn)品質(zhì)量也是非常重要。微生物活性有促進作用，就是出水色度有影響
將化學(xué)除磷劑投加于生化池的后面，這樣便可以完全避免水中多種物質(zhì)與除磷劑發(fā)生反應(yīng),消耗藥劑用量.且不會降低生化池的進水有機碳濃度，影響微生物的脫氮除磷效果。同時還可避免過多投加除磷劑，也會使殘余的藥劑進入生化系統(tǒng)中，對微生物生長造成影響。
將除磷絮凝劑投加于好氧池的出水口端，二沉池的前面投加除磷劑則可以大量減少除磷藥劑的使用量，這是廢水在生化處理的過程中已去除水中大部分磷，并將偏磷、有機磷轉(zhuǎn)化為可通過混凝處理的正磷，大大提高除磷效果和減少除磷劑投加量，減少污泥產(chǎn)量、減少污泥中的磷含量。 所以，化學(xué)除磷藥劑一般投加于生化后，二沉池前，節(jié)省廢水除磷成本和提高達標(biāo)率。?
運用時可將本產(chǎn)品直接投加，或先參加溶解罐，濃度為10～20%，拌和，用泵投加到反響池。本產(chǎn)品適用的pH值規(guī)模廣，在酸性條件下運用效果尤佳，運用量約為100～1000ppm（即0.1～1公斤/噸廢水），依據(jù)廢水中磷酸根的含量不同其用量有所差異，詳細用量一般通過試驗斷定。
試驗時取一定量的原水，參加適量的本產(chǎn)品（如500ppm），將廢水pH值調(diào)節(jié)至7～8，www.hnldscl.com參加少數(shù)聚丙烯酰胺PAM絮凝沉積，過濾取上清液測定磷的含量。（如需處理重金屬，用上清液進行二次處理即可。）AC/PAM與除磷劑攪拌后的反應(yīng)？使用時可將本產(chǎn)品直接投加，或先參加溶解罐，濃度為10～20%，拌和，用泵投加到反響池。本產(chǎn)品適用的pH值規(guī)模廣，在酸性條件下使用作用尤佳，使用量約為100～1000ppm（即0.1～1公斤/噸廢水），依據(jù)廢水中磷酸根的含量不同其用量有所差異，具體用量一般經(jīng)過試驗斷定。The amount of polyferric sulfate added is right, but the PH value of wastewater is not right, and there is no optimum range of PH used in the corresponding reagents. The suitable range of PH value is 4-11, and the optimum range of PH value is 6-9. After purification, the change range of PH value and total alkalinity of raw water is small.
4, the type of water purification products is not correct. According to the characteristics of sewage, choose suitable water purifying agent suitable for its own sewage characteristics, such as polyaluminum chloride, polyaluminum chloride, polyaluminum ferric chloride, aluminum chloride, spray polyaluminum chloride, white polyaluminium chloride, etc., and listen to the advice of professional water treatment division, and give their advice. They are all professional.

Polyferric sulfate
5. The last point to consider is whether the quality of the polyferric sulfate you use meets the national standards, and whether the various indicators of the polyferric sulfate meet the national standards.
At present, the quality of polyferric sulfate is uneven in the market. Compared with the better quality of Polyferric sulfate, the probability of suspended solids will be very low. The better polyferric sulfate has almost no water insoluble solids, so the quality of products is also very important. Microbial activity has a promotive effect, that is, effluent color has an impact.
Adding chemical Dephosphorizer to the back of biochemical pond can compleby avoid the reb between various substances in water and dephosphorizer, consume the amount of reagent, and will not reduce the concentration of organic carbon in the influent of biochemical pond, affecting the effect of nitrogen and phosphorus removal by microorganisms. At the same time, it can avoid excessive dosage of phosphorus removal agents, and also make the residual agents into the biochemical system, which will affect the growth of microorganisms.
Adding phosphorus removal flocculant to the outlet of aerobic tank and phosphorus removal agent in front of secondary sedimentation tank can greatly reduce the use of phosphorus removal agent. This is because most phosphorus in wastewater has been removed in the process of biochemical treatment, and phosphorus migration and organic phosphorus are converted into positive phosphorus which can be treated by coagulation, which greatly improves the effect of phosphorus removal and improves the efficiency of phosphorus removal. Reduce the dosage of phosphorus removal agent, reduce sludge production, reduce phosphorus content in sludge. Therefore, chemical phosphorus removal agents are generally added to the biochemical process, before the secondary sedimentation tank, to save the cost of phosphorus removal from wastewater and improve the rate of reaching the standard. ?
When in use, the product can be directly added or participated in the dissolving tank, the concentration of which is 10-20%, mixed and pumped into the reb tank. The product is suitable for a wide range of pH values, especially in acidic conditions. Its application amount is about 100-1000 ppm (i.e. 0.1-1 kg/ton wastewater). According to the different content of phosphate in wastewater, its dosage is different. The detailed dosage is generally determined by experiments.
During the experiment, a certain amount of raw water was taken and the product (such as 500 ppm) was added. The pH value of the wastewater was adjusted to 7-8. www.hnldscl.com participated in the flocculation and deb of a few PAM. The supernatant was filtered to determine the phosphorus content. (If heavy bls need to be treated, the supernatant can be used for secondary treatment.) Reb of AC/PAM with phosphorus removal agent after stirring? When in use, the product can be directly added or participated in the dissolving tank at the concentration of 10-20%. The product can be mixed and pumped into the reb tank. The product is suitable for a wide range of pH values, especially in acidic conditions. Its usage is about 100-1000ppm (i.e. 0.1-1 kg/ton wastewater).

水污染的破壞很明顯，聚氯化鋁對處理水污染是合理的。生產(chǎn)聚合氯化鋁這些問題一定要重視！
聚氯化鋁生產(chǎn)過程中有哪些相關(guān)問題？
??1.不溶物聚合氯化鋁的堿度對聚合氯化鋁的絮凝效果有很大影響。作為聚合氯化鋁的專業(yè)生產(chǎn)廠家，通過對一些具體實例的對比研究和對聚合氯化鋁絮凝效果的實驗，發(fā)現(xiàn)聚合氯化鋁的絮凝效果與堿度非常相似。
通過焦化廢水混凝處理試驗，得出了焦化廢水處理所需聚合氯化鋁的佳堿度、投加量和pH值范圍，并根據(jù)不同堿度下處理的聚合氯化鋁水鋁含量的不同，得出了利用率。
廢水經(jīng)處理后，鋁含量與聚合氯化鋁的堿度密切相關(guān)，在相同堿度下，pH值對殘余鋁含量有很大影響。根據(jù)聚合氯化鋁的實驗數(shù)據(jù)，當(dāng)pH值接近中性時，水中的殘余鋁含量最小，pH值會使殘余鋁含量增加。當(dāng)聚合氯化鋁的堿度為1.5時，處理后的廢水中鋁的含量很低。
堿度也是聚合氯化鋁生產(chǎn)中必須控制的重要指標(biāo)。由于它對聚合氯化鋁的絮凝效果影響很大，是需要嚴(yán)格執(zhí)行的標(biāo)準(zhǔn)之一。
此外，聚合氯化鋁的絮凝效果不僅與堿度密切相關(guān)，而且受聚合氯化鋁含量和不溶物的影響也很大。在聚合氯化鋁的使用過程中，合理的使用方法也是保證聚合氯化鋁絮凝效果的前提之一
?標(biāo)準(zhǔn)規(guī)定了市售聚氯化鋁的不溶物含量。由于國內(nèi)企業(yè)一般以礦物為原料，礦物等原料一般成分復(fù)雜，需要粉碎并加入粉末中。粉末越細，氧化鋁的溶解速率越高。但是，諸如不溶物質(zhì)的雜質(zhì)更難以沉淀。
??2.產(chǎn)品純度問題
??氧化鋁含量是聚氯化鋁產(chǎn)品的重要指標(biāo)。通常認為含量越高，純度越高，質(zhì)量越好。在中國的聚氯化鋁行業(yè)，除少數(shù)公司外，可以生產(chǎn)一些系列產(chǎn)品和特殊產(chǎn)品。大多數(shù)公司使用鋁土礦，鋁酸鈣和副產(chǎn)品生產(chǎn)單一的低質(zhì)量聚氯化鋁產(chǎn)品，生產(chǎn)規(guī)模小。技術(shù)含量低，產(chǎn)品有效成分氧化鋁含量低，雜質(zhì)多，高效低成本的復(fù)合聚鋁鹽和高純度聚氯化鋁產(chǎn)品少，不能滿足市場需求，特別是造紙工業(yè)的高純度。需要聚氯化鋁產(chǎn)品。
??3.劑量問題
??制備聚氯化鋁的方法很多，但它是一種酸溶液法和堿溶液法，用于實現(xiàn)一定規(guī)模的工業(yè)生產(chǎn)，其中引起生產(chǎn)成本和氧化鋁溶解速率等問題。酸溶解方法比堿溶性方法更實用，酸溶液涉及濃度和劑量等問題。濃度越高，氧化鋁的溶解速率越大，但揮發(fā)性越強，因此應(yīng)適當(dāng)配置濃度。質(zhì)量分?jǐn)?shù)通常約為20％；劑量小，氧化鋁溶解率低。當(dāng)投資額很大時。制備的聚氯化鋁鹽堿度低，腐蝕性強。運輸很困難，因此有必要制定合理的劑量。

三、在造紙廠污水處理中，選用低濁度水的投進份額配備，如作用不明顯可在酌量增加。

Thereafter, the construction of the concept factory was vigorously promoted. By the end of 2014, the preliminary design and site selection work will be completed, the overall design will be completed in 2016, and the project construction approval and construction design will be completed in 2017. Officials said that the first sewage treatment conceptual plant could be completed in 2019.
Wang Hongchen, deputy dean of the Environmental College of Renmin University of China, told reporters that a year and a half ago, the sewage treatment conceptual plant had gathered a group of powerful basic teams to carry out relevant experiments on the spot, build production and R&D centers, speed up the transbation of science and technology, and carry out extensive industrial cooperation. "One is to build the experience center of new technology, promote the research and development, transbation and promotion of new technology; the other is to build the production-oriented research and development center of municipal sewage treatment, and build a new model of new technology from laboratory to practical application. Thirdly, we should promote the development of wastewater treatment technology from laboratory to engineering, and create a new high ground for China's cooperative industries.
According to the introduction, the concept factory initially established the technical route of sustainable water treatment facing the future, and established the business model and innovation model of "ecological complex" and "production-oriented R&D center" guiding industrial development.
For the basic ideas of the technical route, experts said that the main way is to improve energy recovery by carbon segregation, and to achieve the level of water treatment available. The effluent standard of "concept plant" will be much higher than that of current sewage treatment plants, which is of great significance for improving the quality of water environment and promoting ecological construction. "In the future, the conceptual plant will be expanded to an ecological area, like a demonstration of an urban ecological complex, and ultimaby realize that a treatment plant can drive a city's ecosystem." Wang Hongchen said.
"Sewage treatment conceptual plant is an innovative work. It can not simply be regarded as a project, a project, a factory, but a social work to promote the leapfrog development of the industry." Wang Hongchen said so.

Settlement net do not want to do anything is to do a good job of products, after hard struggle, our plant water treatment pharmaceutical products to reach the national GB15892-2003 specification. And through the ISO 9001:2000 international quality system certification, from all aspects of checks, the perbance rate of the contract is 100%, the qualified rate of the products has reached 100%, which has been promulgated by the Municipal Technical Supervision Bureau as a reliable unit of quality and measurement.
According to the dosage of polyaluminium chloride in different water quality, the net settled polyaluminium chloride is introduced.
1. In low turbidity water, the solid polyaluminium chloride product is diluted by adding tap water in proportion of 1:3, and stirred until compleby dissolved.
2. In daily and production wastewater, the polyaluminium chloride product should be added about 30g per ton of wastewater. Then add diluted polyacrylamide products. (If the effect is not obvious, please reduce or increase the product dosage as appropriate. )
3. In the sewage treatment of paper mills, the b share of low turbidity water should be selected and equipped. If the effect is not obvious, it can be increased at a reasonable level.
4. When the turbidity of raw water is 100-500 mg/L, the dosage is 5-10 mg, i.e. 5-10 kg per thousand tons of water. It is better to carry out small-scale tests according to the characteristics of water quality before using, select the appropriate value, and then put it into use.

河道治理用的除磷劑運用方法量投加不會造成不良影響的，畢竟鐵也是微生物生長所需要的微量元素。但是如果投加量過大，則會使污泥活性收到影響，還有疑問可以到環(huán)保.通交流。
生化末端 沒有影響，何況少量的鐵鹽能夠?qū)hosphorus removal agent for road treatment is a kind of material for coagulation and turbidity removal of urban water source and phosphorus removal. It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.
Thus, the phosphorus content in treated drinking water can be reduced to below the threshold value, without changing the original water treatment process, without adding large water treatment structures, which is simple, economical and practical, and can achieve remarkable social and economic benefits.
The amount of phosphorus removal agent used in river regulation will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is too large, the sludge activity will be affected. There are still doubts about environmental protection and communication.
There is no effect on the biochemical end, let alone a small amount of iron salts.
懸浮物上漂
1、操作不當(dāng)，有的是不專業(yè)的人員在實驗中運用了不當(dāng)手法，加入聚合氯化鋁后，攪拌過急過慢都不行，初次實驗，要有專業(yè)的水處理師從旁協(xié)助，這是很重要的一點。
2、加聚合硫酸鐵的量沒有控制好，（加藥過多或過少）這種情況，最容易出現(xiàn)懸浮物上漂。
使用前，將本產(chǎn)品按一定濃度（10-30%）投入溶礬池，注入自來水?dāng)嚢枋怪浞炙猓o置至呈紅棕色液體，再兌水稀釋到所需濃度投加混凝。水廠亦可配成2-5%直接投加，工業(yè)廢水處理直接配 成5-10%投加。 b、投加量的確定，根據(jù)原水性質(zhì)可通過生產(chǎn)調(diào)試或燒杯實驗視礬花形成適量而定，制水廠可以原用的其它藥劑量作為參考，在同等條件下本產(chǎn)品與固體聚合氯化鋁用量大體相當(dāng)，是固體硫酸鋁用量的 1/3-1/4。如果原用的是液體產(chǎn)品，可根據(jù)相應(yīng)藥劑濃度計算酌定。大致按重量比1:3而定。
關(guān)于污水處理使用聚合硫酸鐵上水層出現(xiàn)漂浮物的原因以及解決方法
污水處理1. Improper operation, some non-professional personnel in the experiment used improper techniques, adding polyaluminium chloride, stirring too fast or too slow can not, the first experiment, there must be professional water treatment assistant, this is a very important point.
2. The amount of polyferric sulfate added is not well controlled (too much or too little dosage). In this case, suspended solids are most likely to float.
Before use, the product was put into the alum bath at a certain concentration (10-30%) and stirred with tap water to make it fully hydrolyzed. The product was put into a red-brown liquid and diluted with water until the required concentration was added and coagulated. Waterworks can also be added 2-5% directly, and industrial wastewater treatment can be added 5-10%. B. The determination of dosage depends on the proper amount of alum bed by production debugging or beaker experiment according to the nature of raw water. The other dosage used in water plant can be used as reference. Under the same conditions, the dosage of this product is approximaby equal to that of solid polyaluminium chloride, which is 1/3-1/4 of that of solid aluminium sulfate. If the original liquid product is used, it can be calculated according to the concentration of the corresponding agent. It depends roughly on the weight ratio of 1:3.

3、加聚合硫酸鐵的量對了，但是廢水的PH值不對，沒有在相應(yīng)藥劑的用PH范圍。適應(yīng)水體PH值范圍寬為4-11，PH值范圍為6-9，凈化后原水的PH值與總堿度變化幅度小
4、使用凈水產(chǎn)品的型號不對，根據(jù)污水的特點，選擇適合自己污水特征的凈水劑，如：聚合氯化鋁、聚氯化鋁、聚合氯化鋁鐵、氯化鋁、噴霧式聚合氯化鋁、白色聚合氯化鋁等等，聽從專業(yè)水處理師的指導(dǎo)意見，他們給的意見都是專業(yè)性的。

聚合硫酸鐵
5、最后一點要考慮的就是，你所使用的聚合硫酸鐵，質(zhì)量是否達標(biāo)，聚合硫酸鐵的各項指標(biāo)是否符合標(biāo)準(zhǔn)。
現(xiàn)在市面上聚合硫酸鐵的質(zhì)量參差不齊，相對于質(zhì)量好一些的聚合硫酸鐵在使用過程中，出現(xiàn)懸浮物的幾率會很低的，好一些的聚合硫酸鐵幾乎是沒有水不溶物的，所以產(chǎn)品質(zhì)量也是非常重要。微生物活性有促進作用，就是出水色度有影響
將化學(xué)除磷劑投加于生化池的后面，這樣便可以完全避免水中多種物質(zhì)與除磷劑發(fā)生反應(yīng),消耗藥劑用量.且不會降低生化池的進水有機碳濃度，影響微生物的脫氮除磷效果。同時還可避免過多投加除磷劑，也會使殘余的藥劑進入生化系統(tǒng)中，對微生物生長造成影響。
將除磷絮凝劑投加于好氧池的出水口端，二沉池的前面投加除磷劑則可以大量減少除磷藥劑的使用量，這是廢水在生化處理的過程中已去除水中大部分磷，并將偏磷、有機磷轉(zhuǎn)化為可通過混凝處理的正磷，大大提高除磷效果和減少除磷劑投加量，減少污泥產(chǎn)量、減少污泥中的磷含量。 所以，化學(xué)除磷藥劑一般投加于生化后，二沉池前，節(jié)省廢水除磷成本和提高達標(biāo)率。?
運用時可將本產(chǎn)品直接投加，或先參加溶解罐，濃度為10～20%，拌和，用泵投加到反響池。本產(chǎn)品適用的pH值規(guī)模廣，在酸性條件下運用效果尤佳，運用量約為100～1000ppm（即0.1～1公斤/噸廢水），依據(jù)廢水中磷酸根的含量不同其用量有所差異，詳細用量一般通過試驗斷定。
試驗時取一定量的原水，參加適量的本產(chǎn)品（如500ppm），將廢水pH值調(diào)節(jié)至7～8，www.hnldscl.com參加少數(shù)聚丙烯酰胺PAM絮凝沉積，過濾取上清液測定磷的含量。（如需處理重金屬，用上清液進行二次處理即可。）AC/PAM與除磷劑攪拌后的反應(yīng)？使用時可將本產(chǎn)品直接投加，或先參加溶解罐，濃度為10～20%，拌和，用泵投加到反響池。本產(chǎn)品適用的pH值規(guī)模廣，在酸性條件下使用作用尤佳，使用量約為100～1000ppm（即0.1～1公斤/噸廢水），依據(jù)廢水中磷酸根的含量不同其用量有所差異，具體用量一般經(jīng)過試驗斷定。The amount of polyferric sulfate added is right, but the PH value of wastewater is not right, and there is no optimum range of PH used in the corresponding reagents. The suitable range of PH value is 4-11, and the optimum range of PH value is 6-9. After purification, the change range of PH value and total alkalinity of raw water is small.
4, the type of water purification products is not correct. According to the characteristics of sewage, choose suitable water purifying agent suitable for its own sewage characteristics, such as polyaluminum chloride, polyaluminum chloride, polyaluminum ferric chloride, aluminum chloride, spray polyaluminum chloride, white polyaluminium chloride, etc., and listen to the advice of professional water treatment division, and give their advice. They are all professional.

Polyferric sulfate
5. The last point to consider is whether the quality of the polyferric sulfate you use meets the national standards, and whether the various indicators of the polyferric sulfate meet the national standards.
At present, the quality of polyferric sulfate is uneven in the market. Compared with the better quality of Polyferric sulfate, the probability of suspended solids will be very low. The better polyferric sulfate has almost no water insoluble solids, so the quality of products is also very important. Microbial activity has a promotive effect, that is, effluent color has an impact.
Adding chemical Dephosphorizer to the back of biochemical pond can compleby avoid the reb between various substances in water and dephosphorizer, consume the amount of reagent, and will not reduce the concentration of organic carbon in the influent of biochemical pond, affecting the effect of nitrogen and phosphorus removal by microorganisms. At the same time, it can avoid excessive dosage of phosphorus removal agents, and also make the residual agents into the biochemical system, which will affect the growth of microorganisms.
Adding phosphorus removal flocculant to the outlet of aerobic tank and phosphorus removal agent in front of secondary sedimentation tank can greatly reduce the use of phosphorus removal agent. This is because most phosphorus in wastewater has been removed in the process of biochemical treatment, and phosphorus migration and organic phosphorus are converted into positive phosphorus which can be treated by coagulation, which greatly improves the effect of phosphorus removal and improves the efficiency of phosphorus removal. Reduce the dosage of phosphorus removal agent, reduce sludge production, reduce phosphorus content in sludge. Therefore, chemical phosphorus removal agents are generally added to the biochemical process, before the secondary sedimentation tank, to save the cost of phosphorus removal from wastewater and improve the rate of reaching the standard. ?
When in use, the product can be directly added or participated in the dissolving tank, the concentration of which is 10-20%, mixed and pumped into the reb tank. The product is suitable for a wide range of pH values, especially in acidic conditions. Its application amount is about 100-1000 ppm (i.e. 0.1-1 kg/ton wastewater). According to the different content of phosphate in wastewater, its dosage is different. The detailed dosage is generally determined by experiments.
During the experiment, a certain amount of raw water was taken and the product (such as 500 ppm) was added. The pH value of the wastewater was adjusted to 7-8. www.hnldscl.com participated in the flocculation and deb of a few PAM. The supernatant was filtered to determine the phosphorus content.

水污染的破壞很明顯，聚氯化鋁對處理水污染是合理的。生產(chǎn)聚合氯化鋁這些問題一定要重視！
聚氯化鋁生產(chǎn)過程中有哪些相關(guān)問題？
??1.不溶物聚合氯化鋁的堿度對聚合氯化鋁的絮凝效果有很大影響。作為聚合氯化鋁的專業(yè)生產(chǎn)廠家，通過對一些具體實例的對比研究和對聚合氯化鋁絮凝效果的實驗，發(fā)現(xiàn)聚合氯化鋁的絮凝效果與堿度非常相似。
通過焦化廢水混凝處理試驗，得出了焦化廢水處理所需聚合氯化鋁的佳堿度、投加量和pH值范圍，并根據(jù)不同堿度下處理的聚合氯化鋁水鋁含量的不同，得出了利用率。
廢水經(jīng)處理后，鋁含量與聚合氯化鋁的堿度密切相關(guān)，在相同堿度下，pH值對殘余鋁含量有很大影響。根據(jù)聚合氯化鋁的實驗數(shù)據(jù)，當(dāng)pH值接近中性時，水中的殘余鋁含量最小，pH值會使殘余鋁含量增加。當(dāng)聚合氯化鋁的堿度為1.5時，處理后的廢水中鋁的含量很低。
堿度也是聚合氯化鋁生產(chǎn)中必須控制的重要指標(biāo)。由于它對聚合氯化鋁的絮凝效果影響很大，是需要嚴(yán)格執(zhí)行的標(biāo)準(zhǔn)之一。
此外，聚合氯化鋁的絮凝效果不僅與堿度密切相關(guān)，而且受聚合氯化鋁含量和不溶物的影響也很大。在聚合氯化鋁的使用過程中，合理的使用方法也是保證聚合氯化鋁絮凝效果的前提之一
?標(biāo)準(zhǔn)規(guī)定了市售聚氯化鋁的不溶物含量。由于國內(nèi)企業(yè)一般以礦物為原料，礦物等原料一般成分復(fù)雜，需要粉碎并加入粉末中。粉末越細，氧化鋁的溶解速率越高。但是，諸如不溶物質(zhì)的雜質(zhì)更難以沉淀。
??2.產(chǎn)品純度問題
??氧化鋁含量是聚氯化鋁產(chǎn)品的重要指標(biāo)。通常認為含量越高，純度越高，質(zhì)量越好。在中國的聚氯化鋁行業(yè)，除少數(shù)公司外，可以生產(chǎn)一些系列產(chǎn)品和特殊產(chǎn)品。大多數(shù)公司使用鋁土礦，鋁酸鈣和副產(chǎn)品生產(chǎn)單一的低質(zhì)量聚氯化鋁產(chǎn)品，生產(chǎn)規(guī)模小。技術(shù)含量低，產(chǎn)品有效成分氧化鋁含量低，雜質(zhì)多，高效低成本的復(fù)合聚鋁鹽和高純度聚氯化鋁產(chǎn)品少，不能滿足市場需求，特別是造紙工業(yè)的高純度。需要聚氯化鋁產(chǎn)品。
??3.劑量問題
??制備聚氯化鋁的方法很多，但它是一種酸溶液法和堿溶液法，用于實現(xiàn)一定規(guī)模的工業(yè)生產(chǎn)，其中引起生產(chǎn)成本和氧化鋁溶解速率等問題。酸溶解方法比堿溶性方法更實用，酸溶液涉及濃度和劑量等問題。濃度越高，氧化鋁的溶解速率越大，但揮發(fā)性越強，因此應(yīng)適當(dāng)配置濃度。質(zhì)量分?jǐn)?shù)通常約為20％；劑量小，氧化鋁溶解率低。當(dāng)投資額很大時。制備的聚氯化鋁鹽堿度低，腐蝕性強。運輸很困難，因此有必要制定合理的劑量。

三、在造紙廠污水處理中，選用低濁度水的投進份額配備，如作用不明顯可在酌量增加。

Thereafter, the construction of the concept factory was vigorously promoted. By the end of 2014, the preliminary design and site selection work will be completed, the overall design will be completed in 2016, and the project construction approval and construction design will be completed in 2017. Officials said that the first sewage treatment conceptual plant could be completed in 2019.
Wang Hongchen, deputy dean of the Environmental College of Renmin University of China, told reporters that a year and a half ago, the sewage treatment conceptual plant had gathered a group of powerful basic teams to carry out relevant experiments on the spot, build production and R&D centers, speed up the transbation of science and technology, and carry out extensive industrial cooperation. "One is to build the experience center of new technology, promote the research and development, transbation and promotion of new technology; the other is to build the production-oriented research and development center of municipal sewage treatment, and build a new model of new technology from laboratory to practical application. Thirdly, we should promote the development of wastewater treatment technology from laboratory to engineering, and create a new high ground for China's cooperative industries.
According to the introduction, the concept factory initially established the technical route of sustainable water treatment facing the future, and established the business model and innovation model of "ecological complex" and "production-oriented R&D center" guiding industrial development.
For the basic ideas of the technical route, experts said that the main way is to improve energy recovery by carbon segregation, and to achieve the level of water treatment available. The effluent standard of "concept plant" will be much higher than that of current sewage treatment plants, which is of great significance for improving the quality of water environment and promoting ecological construction. "In the future, the conceptual plant will be expanded to an ecological area, like a demonstration of an urban ecological complex, and ultimaby realize that a treatment plant can drive a city's ecosystem."

According to the dosage of polyaluminium chloride in different water quality, the net settled polyaluminium chloride is introduced.
1. In low turbidity water, the solid polyaluminium chloride product is diluted by adding tap water in proportion of 1:3, and stirred until compleby dissolved.
2. In daily and production wastewater, the polyaluminium chloride product should be added about 30g per ton of wastewater. Then add diluted polyacrylamide products. (If the effect is not obvious, please reduce or increase the product dosage as appropriate. )
3. In the sewage treatment of paper mills, the b share of low turbidity water should be selected and equipped. If the effect is not obvious, it can be increased at a reasonable level.
4. When the turbidity of raw water is 100-500 mg/L, the dosage is 5-10 mg, i.e. 5-10 kg per thousand tons of water. It is better to carry out small-scale tests according to the characteristics of water quality before using, select the appropriate value, and then put it into use.
