平庄旷区煤质属较年青的褐煤,矸石极易泥化,致使洗水浓度不断增高,严重影响选煤分选效果,造成煤泥水大量流失。为探求褐煤煤泥水处理的可行性及选取最佳工艺系统,对平庄矿区西露天矿选煤厂生产用水及煤泥水进行了压滤及絮凝试验,结果表明,在适合条件下平庄矿区煤泥水是可压滤的可絮凝的,并推荐了最佳的压滤条件参数。 Coal in Pingzhuang Kuang District is relatively young lignite, gangue extremely easy to mud, resulting in continuous increase in the concentration of washing water, seriously affecting the selection of coal separation effect, resulting in a large loss of slime water. In order to explore the feasibility of lignite slime water treatment and select the best process system, the production water and slime water of the West Open Pit Coal Preparation Plant in Pingzhuang Mining Area were subjected to pressure filtration and flocculation tests. The results show that under suitable conditions, slime water Is pressure-fillable and flocculable, and recommends the best filter press conditions.
