摘　　要：将传统的化学处理法与絮凝技术相结合,配制选择性好的RSL复合絮凝剂对电镀铬废液进行净化处理、纯化等,得到纯度较高的Cr(VI)液;使Cr(VI)液在低温下结晶,即可得到重要的化工原料K2Cr2O7晶体 既防治了铬对环境的污染,实现电镀废水的零排放。Combinating the traditional chemical method with chemical flocculation technology, we found a new complex flocculation to treat the electroplating chromium wastewater. By treating preliminarily, purring and purifying, recrystalizing, we obtained K2Cr2O7 crystal with high fineness at low temperature. So we not only prevented the chromium pollution to ecological environment but also found out the value of wastewater.
