摘要
选用石英重砂加载混凝处理高悬浮矿井水为研究对象,分析矿混凝剂种类(聚合氯化铝(PAC)、非离子型聚丙烯酰胺(PAM)和聚合氯化铁(FeCl_(3))等)对石英重砂加载混凝处理高悬浮物矿井水效率的影响。结果表明:投加适量的PAC有助于提升单位时间内加载混凝沉淀处理的效率和速率,而过量的PAC投加会降低其处理效率和速率。投加PAM可有助于提升单位时间内加载混凝沉淀处理的效率和速率,但投加量的作用可忽略。适量投加FeCl_(3)可有效提升加载混凝沉淀高悬浮煤粉矿井水的去除效率和速率,但对高悬浮岩粉矿井水的作用较弱。该研究成果为保障重砂加载混凝处理高悬浮矿井水的效率,保障我国煤炭矿区水资源综合利用具有重要的作用。
The typical high suspended mine water was selected to analyze the effect of PAC,PAM and FeCl_(3) on the efficiency of high suspended matter mine water treated by loading coagulation with heavy sand.The results showed that appropriate dosage of PAC contributed to improving the efficiency and rate of loading coagulation with heavy sand,while excessive PAC reduced.The addition of PAM improved the efficiency and rate of loading coagulation with heavy sand,while the effect of the dosage can be ignored.Appropriate amount of FeCl_(3) can effectively enhance the removal efficiency and rate of high suspended coal mine drainage suspended coal in mine water,while its effect on high suspended rock mine drainage was relatively weaker.These results can effectively ensure the efficiency of high suspended matter mine water treated by loading coagulation with heavy sand and provide the comprehensive utilization of water resources in coal mining China.
