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 K2Cr2O7 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.
