摘　　要：通过分析电解锰废水产生过程,确定了削减废水量和去除废水中Cr(Ⅵ)是实现电解锰工艺废水零排放的关键。中试试验结果表明:通过全过程控制,阴极电解液挟带量和钝化液挟带量分别削减65%,清洗废水量削减80%;用离子交换法几乎完全去除废水中的Cr(Ⅵ),废水可返回使用,有效解决了电解锰废水处理过程中的铬渣二次污染和氨氮严重超标问题。By analyzing the source of electrolytic metal manganese problems for realizing zero discharge of EMM wastewater （EM were experimental results showed the electrolyte and passivation liquid on M） wastewater, the two key determined. The pilot-test the surface of cathode board could reduce by 65% ,and wastewater from product washing reduced by 80% by whole process control technology. The Cr（Ⅵ） in EMM wastewater was almost whole removed using anion-exchange resin. Then the EMM wastewater was reused in production process. The problems of secondary pollution caused by Cr（Ⅵ） residue and NH3-N excess in current EMM wastewater treatment were solved effectively.
