答：工业污废水处理是为什么保护我们的人居环境，同时也是我们的基本国策之一！根据我公司承接的污水处理工程经验，与一些污水处理厂的技术人员的介绍得知！工业污废水处理中常用的药剂有四种，分别为聚合氯化铝无机盐絮凝剂、聚合硫酸铁无机盐絮凝剂、专用絮凝剂和聚丙烯酰胺！同时工业污水处理常用4种药剂当中的专用絮凝剂有脱色剂、除磷剂、除油剂、重金属捕捉剂！

　　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!
