聚合氯化鋁的小試一般是先將聚合氯化鋁配置成5%濃度的水溶液來進行實驗。通常為了方面可以稱取5g的聚合氯化鋁固體，然后添加到100ml的水中，就可以配置成聚合氯化鋁的水溶液。然后將需要處理的絮凝劑主要用于給水和污水處理領域。它是添加到廢水中的聚合物凝結劑。在聚合物凝結劑溶解后，形成高分子聚合物。
高聚物的結構是線性結構，線的一端拉出一個微小的粒子，另一端拉出另一個微小的粒子，并起到兩個遠處粒子之間的橋梁作用，使粒子＃ ##逐漸變大，最終形成大顆粒絮狀物（俗稱絹花），加速顆粒沉降。 Flocculants are mainly used in the field of water supply and sewage treatment. It is a polymer coagulant added to wastewater. After the polymer coagulant dissolves, the polymer is formed.
The structure of polymer is a linear structure. One end of the line pulls out a tiny particle, the other pulls out another tiny particle, and acts as a bridge between two distant particles, which gradually enlarges the particle # and eventually forms a large 聚合氯化鋁的水不溶可以通過溶解聚合氯化鋁來觀察。一般情況下聚合氯化鋁溶解后的水溶液較為渾濁時，就表示聚合氯化鋁中的水不溶物較多，反之溶解后的聚合氯化鋁水溶液越清澈，就表示聚合氯化鋁中的水不溶物含量越低。需要注意的是，聚合氯化鋁在固體狀態下很難直接分辨聚合氯化鋁中水不溶物的情況。
大多時候聚合氯化鋁的固體在我們進行直接觀察時，會因為聚合氯化鋁中有一些顆粒物質或者塊狀物，尤其在滾筒型的聚合氯化鋁中存在更多，就異味聚合氯化鋁的產品質量不行，其實這是不對的。聚合氯化鋁的水不溶物一般是由于生產原料和生產工藝決定的construction, and do not pollute building water.
污水處理廠常用的外部碳源是甲醇，工業葡萄糖等。甲醇應該是最理想的反硝化補充碳源，但其高成本，高毒性和運輸困難逐漸被其他產品所取代。工業葡萄糖通常用作額外的碳源。過程測試水質測試中心在工業葡萄糖成分的測量和計算方面做得很好。在實驗室中，以1/100的比例添加工業葡萄糖，測量COD和BOD含量，并計算每10,000平方米污水的工業葡萄糖的理論劑量。劑量的劑量是根據在《給水排水設計手冊》的第五體積的多級活性污泥法脫氮處理的碳源的計算公式根據所述過程實驗的結果計算，并且計算的工業葡萄糖的劑量。碳源劑量應在上限和下限之內。上限劑量應確保出水COD值不超過標準。下限劑量應確保反硝化細菌的C/N比，以確保總出水氮達到標準。去除1千克總氮需要4.2千克COD，1千克葡萄糖相當于1.1千克COD，因此需要3.9千克葡萄糖才能去除1千克總氮。九公里污水處理廠的日均處理能力為冬季每天20,000平方米，夏季每天50,000平方米。手動添加劑量方法，位置為二級充氣生物過濾器的東側出水通道。劑量周期為2小時。污水用于在通道和清水箱中流動以自然地混合和混合。同時，根據COD，氨氮和紫外線消毒室內全氮的在線監測數據，工藝技術人員實時調整工業葡萄糖用量，以滿足出水水質要求。
6. When the water temperature is high in summer, the dissolution time of PAM to polymer should be guaranteed for 1 hour. When the water temperature is low in winter, the dissolution time of flocculant polymer should be guaranteed for 1.5 hours. Incomplete dissolution will affect the use effect.
常用的絮凝劑是聚丙烯酰胺（PAM）。
絮凝劑重要的控制條件是：1。劑量與本身的性能和凝結產生的總懸浮固體，需要通過實驗確定; 2.動力學條件，特別是快速攪拌過程中的動力學條件，很多實際的
項目控制不好，導致結果不佳; 3，其他條件不是很重要，調整劑量和混合效果非常好，特別是控制動態條件，有必要去體驗
水下非分散混凝土絮凝劑是由水溶性聚合物，表面活性物質等組成的粉狀鉍摻合料，具有很強的抗分散性和良好的流動性，實現了水下混凝土的自流平。
自密實，在水下施工期間抑制水泥和骨料的分散，不污染建筑用水。
當材料的水下焓在水中下降0.3至0.5米時，抗壓攪拌速度優選為60至120rpm。
5。在溶解過程中，添加絮凝劑的速度應盡可能慢，并將其慢慢撒入水的渦流中，以防止顆粒在進入水后相互粘連。
6。當夏季水溫較高時PAM對聚合物的溶解時間保證1小時。當冬季水溫較低時，絮凝聚合物的溶解時間保證1.5小時。不完全溶解會影響使用效果。
污水進行取樣并分配成相同的若干份，然后就可以使用聚合氯化鋁進行小試。
用滴管將聚合氯化鋁的水溶液慢慢添加到污水中，并使用玻璃棒進行攪拌，觀察污水的絮凝效果，如果出現礬花就表示聚合氯化鋁的絮凝效果較好，然后將不同的量的聚合氯化鋁水溶液添加到污水的樣品中，攪拌靜置一段時間后觀察看哪個污水樣品更加干凈清澈。在使用聚合氯化鋁的過程中，有時候需要添加一些其他的助凝劑如聚丙烯酰胺等，這樣會加快污rious water treatment agents, committed to the continued use of green and environmentally friendly renewable resources, a lot of investment in scientific research funds, the primary product is polyacrylamide flocs. Coagulation series, polyaluminium chloride series, polyferric sulfate series, alkaline aluminium chloride series and so on are all praised by the national customers. We will continue to produce high-quality products to repay customers for our support of the production and market analysis of polyacrylamide, we can get the following understandings:
1、我國已有10個5000t/a以上的PAM生產廠，其中有5個萬噸級PAM大廠。這典 廠家占全國年產量的56%，生產的集中度正在提高。PAM全行業的總銷售額為62億元。
4、由于一些油田淡水資源的缺乏及降低生產成本、環保等方面的要求，三次采油多采用污水配制聚合物，對耐溫抗鹽聚合物的需求越來越多，取代高分子聚丙烯酰胺的趨勢，而我國能夠生產抗鹽聚合物的企業只有三四家，總生產能力在6×104t左右，遠遠不能滿足三次采油的需求，因此，抗鹽聚丙烯酰胺具有廣闊的應用前景。
There are 10 PAM factories with a capacity of more than 5000t/a in China, of which there are 5 large PAM factories with a capacity of 10,000 tons. This manufacturer accounts for 56% of the country's annual output, and the concentration of production is increasing. The total sales volume of PAM industry is 6.2 billion yuan.
2. The main uses of PAM are oil field, water treatment and papermaking, 高分子量是重要的絮凝劑，它能夠制造出親水而水不溶性的凝膠，它對許多團體外表和溶解物質有良可以作為凈水藥劑使用，也可以在造紙領域被當做助留劑使用，部分造紙使用草漿纖維較短，細胞雜質較高，導致了紙張強度較差，抄紙過程中濾水困難。對于此問題處理辦法有兩種：機械截留和膠體絮凝。
運用聚合氯化鋁處理了造紙進程由酸性改為中、堿性規模，紙漿中的陰離子雜質的問題，紙機操作以及紙質量的一系列問題，聚合氯化鋁帶有陽電荷，可以有效的控制陰離子的作用，有利于紙張濾水性
and there is still room for increasing the amount of PAM. The second largest market, water treatment, has accounted for one fourth of the total PAM market and will grow faster than the oilfield market. At present, the paper-making market is relatively concentrated and occupied by four or five PAM factories, some of which have strong specificity. The proportion of cationic polyacrylamide is only 13%. From the future development of water treatment market, the development of cationic polyacrylamide will have a faster growth rate.
3. At present, PAM products occupy an important position in China's energy strategy and water-saving strategy, and are indispensable products. It will play a more active role in the energy crisis in China and the world as well as in the next more serious water resources crisis.
4. Because of the shortage of freshwater resources in some oilfields and the requirement of reducing production cost and environmental protection, sewage is mostly used to prepare polymers for tertiary oil recovery. There is an increasing demand for temperature-resistant and salt-resistant polymers, which tends to replace polymer polyacrylamide in an all-round way. However, only three or four enterprises in China can produce salt-resistant polymers. The total production capacity of salt-resistant polyacrylamide is about 6 *104t, which can not meet the demand of tertiary oil recovery. Therefore, salt-resistant polyacrylamide has broad application prospects.
In addition, the demand for polyacrylamide products will increa
se considerably in recent years due to the attention paid by our government and relevant enterprises to sewage treatment. Most domestic enterprises plan to build polyacrylamide projects mainly for urban sewage treatment. According to experts'prediction, the annual demand of municipal wastewater treatment in Shanghai alone will reach 1 x104t. It can be expected that the application potential of polyacrylamide products in wastewater treatment will be tremendous.
It can be seen that salt-resistant polyacrylamide products have broad application prospects in tertiary oil recovery and sewage treatment.
