混凝吸附法去除电镀废水中铬的试验

Test of Removing Cr^(6+) in Electroplating Waste Water Using Coagulating and Adsorbing Method

介绍一种以热电厂炉渣为主，加入少量硫酸亚铁及明矾配成的混凝吸附剂。用于处理电镀废水中的Cr（Ⅵ），得到较好的效果，其去除率达到99％以上，为电镀络废水的处理提供了一条以废治废的有效途径。

In this paper, a coagulant made from cinder of power plant mixed with a little FeSO4 and alum is introduced. A good treating result with this coagulant to remove Cr6+ in the electroplating waste water is obtained. The ratio of removing chromium is more than 99%.
