在分析了高浓度煤泥水的性质及其难于处理的原因之后，提出了采用ＣａＣｌ２＋ＰＡＭ（聚丙烯酰胺）混凝沉淀法处理该种废水的方法，并通过实验确定了主要技术参数。实验结果表明，该方法处理效果显著，不仅有较高的清水分离率，而且处理的水的各项指标均达到国家排放标准。 After analyzing the properties of high concentration slime water and the reasons why it is difficult to handle, a method of using CaCl2 + PAM (polyacrylamide) coagulation and sedimentation to treat the wastewater was proposed. The main technical parameters were determined through experiments. The experimental results show that the method has significant effect, not only high water separation rate, but also the indicators of the treated water meet the national emission standards.
