摘要
洗煤废水中悬浮物和COD浓度很高,颗粒表面带有较强的负电荷,细小颗粒含量大且过滤性能不好。本文将絮凝沉淀和BAF组合为主要工艺来处理洗煤废水并回用,控制了污染物的排放,提高污水的利用率。
High concentrations of suspended solids and COD in waste water washed coal particle surface with astrong negative charge, large and small particles content filtering performance is bad. In this paper, the flocculationprecipitation and BAF combination as the main process to deal with coal washing wastewater and recycle, to controlthe emissions of pollutants, improve the utilization rate of wastewater.
