摘要
研究了CH型絮凝剂对废水中重金属离子去除效果 ,结果表明 ,对废水中Ni2 +、Cr6 +等单一离子 (浓度 2 0～ 4 0mg/L)的去除率大于 90 % ,对混合废水中的Cu2 +、Zn2 +、Ni2 +、Cr3+、Cd2 +等 (各离子浓度 2 0～ 4 0mg/L)的去除率均大于 96%。
A study was made on removing the heavy metal ions in waste water with CH type of flocculant. The results showed that the removing ratio was more than 90% when the ions such as Ni 2+ , Cr 6+ , etc, (20～40mg/L) exist in waste water individually, while more than 96%, when all Cu 2+ , Zn 2+ , Ni 2+ , Cr 3+ , Cd 2+ , etc (each 20～40mg/L) coexist in waste water.
