摘　　要：电池生产过程排放的污水含汞、锌、锰等重金属污染物和ＣＯＤ等有机污染物。该试验通过调节污水的ｐＨ值（７５～８５），利用进入ＥＷＰ高效污水净化器的污水自身生成的Ｚｎ（ＯＨ）２絮凝沉淀物形成的吸附过滤流化床对污水进行净化。试验结果表明可达到：出水的汞为００００９２ｍｇ／Ｌ，去除率为９６２％；锌去除率为９９１％；锰去除率为５５１％；ＣＯＤ去除率为１９６％；ＢＯＤ去除率为２８３％。During the battery production,the wastewater would drain with some heavy metal pollutants and organic pollutants like Hg,Zn,Mn,COD and BOD.By this EWP unit test,we want to research if we can use Zn(OH) 2 flocculate caused by influent wastewater as adsorption layer bed to purify the water while adjusting the pH value to 7.5～8.5.By using the EWP unit,Hg can be reduced into 0.000 92 mg/L with the removing rate of 96.2%;Zn removing rate is 99.1%;Mn removing rate is 55.1%;COD removing rate is 19.6%;BOD removing rate is 28.3%.
