洗煤废水难处理的原因及处理方法研究

Cause of Difficult Disposal of Waste Water after Washing Coal and Research on the disposal method

分析了洗煤废水的特点及其难处理的原因，并依此提出用石灰和聚丙烯酰胺进行混凝沉淀的处理方法，同时对其实际工程应用、混凝机理进行了简单的介绍和分析。

Abstract The Features of waste water after washing coal and the cause of its difficult disposal are analyzed. A hadling method is proposed of settling by mixing and coagulating with limestone and polyacylamide. Brief introduction and analysis are made on the practical engineering application and the mixing and coagulating mechanism.
