含铬、镍电镀废水的治理

Treating electrodynanics Waste Water Cotaining Chromium And Nickel

采用氧化还原—中和—絮凝沉淀综合工艺处理含铬、镍等离子的电镀废水．总铬去除率达99．5％，镍离子去除率达99．1％．处理后的废水总铬浓度平均为0．22mg／L，镍离子浓度平均为0．25mg／L．处理后水质清澈透明，各项水质指标均符合国家及辽宁省污水排放标准．

The article use oxyen-restore neutralization - flocculant precipitation synthetical technology to treat electrodynamics wastewater which contain some chromeions and nickelions. The elimination rate of total chromeions reach 99. 5 % and the elimination rate for nickelions reach 99. 1 % average concentration of total chromium in waste water after treated is 0. 22mg/L and nickel is 0. 25mg/L. Water after treated is limpid and transparent. Every target about quality of treated wastewater completely accord with the standard of nation and province Liaoning about draining the polluted water.
