Abstract:
Preliminary exploration of the feasibility to treat the waste water containing nickel ion(heavy metalion)with flocculat ion- microelectrolysis method. The process is to t reat Ni/Ni2+-containing wastewater (named Renickel waste water), and to decrease the total N i concentration in the drainage process 1.0mg/L by adjusting pH value and sedimentat ion. The effect of COD removal reaches to 20%~40%.
Key words:

摘要：
初步探索用絮凝 -微电解法处理含重金属离子———镍废水的可行性。工程以雷尼镍废水为处理对象,确定用絮凝 -微电解法处理含Ni和Ni2+ 废水,并通过调节pH和沉降,使工艺排水总镍质量浓度≤ 1.0mg/L,对废水的COD的去除效果达 2 0 %～ 4 0 %。
