摘要
研究了过氧化钙处理剂对机械工业废水中重金属离子锰、铜、锌、铬的处理工艺 ,以及过滤方法对重金属离子去除率的影响。处理的最佳条件为 :过氧化钙用量 0 .1 %～ 0 .2 % ,处理时间 30 m in,处理温度为室温 ,处理过程中不需调整 p H。
In this paper, peroxide of calcium agent for handling the ion of manga nese, copper, zinc and chromium in industrial wastewater and the influence of th e filtering method about removal rate of heavy metallic ion were studied. The re sults show the best conditions of handling are: quantity of peroxide calcium 0. 1%～0.2%,handle time 30 min,room temperature. And in this course, pH value is n ot adjusted.
