答：工業污廢水處理是為什么保護我們的人居環境，同時也是我們的基本國策之一！根據我公司承接的污水處理工程經驗，與一些污水處理廠的技術人員的介紹得知！工業污廢水處理中常用的藥劑有四種，分別為聚合氯化鋁無機鹽絮凝劑、聚合硫酸鐵無機鹽絮凝劑、專用絮凝劑和聚丙烯酰胺！同時工業污水處理常用4種藥劑當中的專用絮凝劑有脫色劑、除磷劑、除油劑、重金屬捕捉劑！

　　A: industrial wastewater treatment is why we protect our living environment, and it is also one of our basic national policies! According to the experience of sewage treatment projects undertaken by our company, we learned from the introduction of some technicians of sewage treatment plants! There are four kinds of agents commonly used in industrial wastewater treatment, namely polyaluminum chloride inorganic salt flocculant, polymerized ferric sulfate inorganic salt flocculant, special flocculant and polyacrylamide! At the same time, among the four commonly used agents for industrial sewage treatment, the special flocculants are decolorizer, dephosphorization agent, degreaser and heavy metal catcher!
