高浓度矿井水的处理方案

在采煤过程中 ,会涌出一定量的矿井水 ,经煤水分离后的矿井水所含煤泥悬浮物浓度较高 ,要进一步处理才能外排或利用。针对一定的矿井煤泥水的特性 ,采用高效浓缩机一次处理、迷宫式斜板沉淀池二次处理压缩机回收煤泥的矿井水处理方案 ,出水悬浮物质量浓度降至 70mg/L以下 ,符合国家一级排放标准。文中介绍了该处理工艺方案及实践效果

Treatment scheme of high concentration mine water

During coal mining,a certain amount of mine water will effuse.The concentration of the mine water is higher,after the coal-water separation.It needs further treatment,so as to discharge and reuse.On the basis of the character of the slime water,the firsttreatment is carried out in a concentration machine,the second treatment is carried out in labyrinth-lamella setting basin and the mine water of the slime is recovered in a compressor.The concentration of the outlet water is under 70 mg/L,and up to the First Grade National Discharge Standard.The treatment scheme of mine water and its effect are introduced.
