树枝状聚合物在含铜废水深度处理中的应用

Application of Dendrimer in Advanced Treatment of Copper Containing Wastewater

在电子厂含铜废水深度处理中,已普遍使用反渗透作为深度处理的重要一环。但是由于中水水质复杂,常会在各级反渗透进水侧甚至在产水侧发现红色污染物,对反渗透系统造成更严重污堵。本文以江苏某电子厂含铜废水深度处理项目为案例,介绍了使用树枝状聚合物延长红色污染物出现的时间,延长反渗透清洗周期的应用。

inelectronic factorycoppercontaining wastewater advanced treatment,commonlythereverse osmosissystemplays an important role.However,because of the complexity quality of the wastewater,red pollutants are often found in the feed water,even foundin the permeate water of the reverse osmosis system,andthered pollutants willcause serious pollution blocking.Inthispaper,takethecaseas advanced treatment of copper containing wastewater from an electronic factory in Jiangsu Province,and introduces the application of dendrimer to prolong the time of red pollutants and the period of the reverse osmosis cleaning.
