氯化钙+PAM处理高浓度洗煤废水的实验研究

Experimental Study on the High Concentration Coal-Washing Wastewater Treatment by Using CaCl_2 Associated with PAM

本文研究了高浓度洗煤废水的处理方法,发现采用氯化钙+PAM联用处理工艺可以达到很好的处理效果,使出水满足回用洗煤的标准。氯化钙和PAM的最佳投药量分别是600mg/L和50mg/L。

This paper studies on the treatment methods of a high concentration of coal - washing wastewater, finding out that itcan achieve a good treatment effect by using CaCl2 associated with PAM. The effluent can meet the reuse standard of coal washing. The optimal doses of CaCl2 and PAM are 600 mg/Land 50 mg/L.
