隨著(zhù)早起工業(yè)發(fā)展過(guò)快，這樣造成了污水的種類(lèi)比較多，冶理起來(lái)比較頭疼，因為要根據每種行業(yè)污水進(jìn)行對癥下藥，所以處理起來(lái)相對難度大,以聚合氯化鋁為母體,摻入其他藥劑，調配成復合PAC，處理污水能得到驚喜的效果。
　　With the rapid development of early industry, there are many kinds of sewage, which causes a headache in metallurgy. Because it is difficult to treat the sewage according to the specific conditions of each industry, polyaluminium chloride is used as the matrix, mixed with other chemicals, and mixed into composite PAC. The sewage can be treated with surprising results.
　　首先，由于我們的聚合氯化鋁分子結構大，吸附能力強，用量少，處理成本低。其溶解性好，活性高，在水體中凝聚形成的礬花大，沉降快，比其他無(wú)機絮凝劑凈化能力大2-3倍。聚合氯化鋁適應性強，受水體PH值和溫度影響小，原水凈化后能達到國家引用水標準，處理后水質(zhì)中陽(yáng)、陰離子含量低，有利于離子交換處理和高純水的制備。

　　First of all, because of the large molecular structure, strong adsorption capacity, low dosage and low treatment cost of polyaluminium chloride. It has good solubility and high activity. The alum flower formed by coagulation in water body is large, settling is fast, and its purification capacity is 2-3 times larger than other inorganic flocculants. Polyaluminium chloride has strong adaptability and is little affected by the pH value and temperature of water body. After purification, the raw water can reach the national standard of drinking water. The content of cation and anion in the treated water is low, which is conducive to the preparation of ion exchange treatment and high-purity water.
　　然后，聚合氯化鋁腐蝕性小，操作簡(jiǎn)便，能改善投藥工序的勞動(dòng)強度和勞動(dòng)條件。當聚合氯化鋁絮凝劑和聚丙烯酰胺進(jìn)行配合使用的時(shí)候，我們應視不同的水質(zhì)按照先后順序投加，而其藥量也要通過(guò)試驗確定。其實(shí)，聚合氧化鋁也可以單用，但其價(jià)格比PAC高，效果不比加PAC的水質(zhì)差，當然要分水質(zhì)情況而定。如果處理水要排放的話(huà)，丙烯酰胺單體帶有毒性也是需要考慮的一個(gè)問(wèn)題。懸濁物比較多的時(shí)候一般單用PAM也可以了。
　　Then, the polyaluminium chloride is less corrosive and easy to operate, which can improve the labor intensity and working conditions of the dosing process. When polyaluminium chloride flocculant and polyacrylamide are used together, we should add them in order according to different water quality, and the dosage should also be determined by test. In fact, Polyalumina can also be used alone, but its price is higher than that of PAC, and the effect is not worse than that of PAC. Of course, it depends on the water quality. If the treated water is to be discharged, the toxicity of acrylamide monomer should also be considered. When there is a lot of suspended matter, PAM alone can also be used.
