摘要

采用间歇式电解槽对垃圾渗滤液进行预处理,考察了电解电压、Cl-质量浓度、进水 pH等因素对电解效果的影响,从而确定在最佳操作条件下电解装置对矿化程度比较高的垃圾渗滤液各项指标的去除效果.结果表明:电解法对矿化程度比较高的垃圾渗滤液(COD≤2 000 mg·L-1、NH4+-N质量浓度小于2 000 mg·L-1)有较好的处理效果,可有效去除废水中的COD、NH4+-N和色度,对提高垃圾渗滤液的可生化性有一定的贡献.

Abstract

A intermittent electrolytic trough system was applied for the preliminary treatment of landfill leachate.The influence of voltage,Cl-mass concentration and pH on the removal effect of various indexes of landfill leachate with high mineralization degree was studied.The results showed that electrolytic oxidation process was effective on the treatment of landfill leachate with high mineralization(COD≤2 000 mg·L-1,NH4+-N mass concentration≤2 000 mg·L-1).COD,NH4+-N and chroma could be removed effectively and the biodegradability of leachate was also improved.
