It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.2020年能不能重新啟動 恢復出廠設置呢 聚合氯化鋁 聚丙烯酰胺 凈水行業的路如何前行
2020年你在哪里 我在家 什么時間復工 不知道 這是很多業務人員朋友之間的聊天 聚丙烯酰胺和聚合氯化鋁的使用主要是用于污水處理 污水廠 印染廠 造紙廠 食品廠 這些企業很多都是中小型企業 復工復產審核難度高 但是有一點生活需要繼續 只有社會在運轉 人類在生活就要排
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 regulatio
??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，用于實現一定規模的工業生產，其中引起生產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，但揮發性越強，因此應適當配置濃度。質量分數通常約為20％；劑量小，氧化鋁溶解率低。當投資額很大時。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。

n will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is 安徽聚合氯化鋁在我們的生活中非常的常見，是一種比較高效無機高分子的絮凝劑，在對于水處理凈化方面非常的重要，但是針對于我們現在市場上面這么多的聚合氯化鋁，對于質量的選擇也是非常的重要的，接下來，安徽聚合氯化鋁常見總結了五個方面教你怎么樣去判斷聚合氯化鋁的質量好壞。
廣東省廣州市醋酸鈉廠家報價表3.就是成本問題，當我們投加硫酸亞鐵過量是，不僅僅是藥劑本身成本增加，我們在使用其它協助藥劑時的成本也同樣增加，另外包括污泥處理的費用，人工費用等也再增加。所以，我們在使用硫酸亞鐵時一定要控制好使用的量，這樣我們不僅能夠節省開支，同樣也可以得到非常理想的效果。一般將它配制成10%--25%的水溶液充分溶解后，投加在廢水處理的初沉池前面或者生化處理的后面，去除水中的磷與cod。使用時在水處理中是作為混凝劑或脫色劑使用的硫酸亞鐵因為具有混凝脫色作用若將其直接用來處理廢水中的懸浮物時，便無需配制成溶液進行投加，可直接將固體投加進混凝池里面，充分攪拌，使其反應充分。
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
關于污水處理使用聚合硫酸鐵上水層出現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 formed 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 approximately 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.

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 completely avoid the reaction 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. ?
