摘　　要：分析了某煤矿在处理含悬浮物矿井水过程中的问题,如混凝剂投加量不合理,未实现水质、水量的系统监控,排泥不及时,自动化程度不高,煤泥压滤效果差。根据该煤矿矿井水的水质特点,进行了现场混凝试验,试验确定最佳投药量:PAC投加100 mg.L-1、PAM投加0.5 mg.L-1。通过分析与总结提出了改进对策:依据混凝搅拌试验实施科学加药,加强系统监控及自动化控制,改善污泥处理系统。Problems in the operation of treating mine water with a great concentration of sus- pended solids by a certain coal were analyzed, such as irrational coagulant dosages, unrealized systemic monitor of water quality and quantity, untimely sludge discharge, and bad filter-press effects of coal sludge. According to the characteristics of mine water quality, spot coagulation experiments were carried out. The optimum dosages got by the experiments were PAC dosage of 100 mg.L-1 and PAM dosage of 0.5 mg.L-1. Solutions were proposed by analyses and summaries： scientific dosages got by experiments of coagulation and agitation, improvements of systemic monitor and automatic control, improvements of sludge treating system.
