矿区自来水厂的“翻池”现象及对策

Phenomenon of "Sediment Upturning" Occurring in Mining Water Treatment Plant and Its Countermeasures

某矿区自来水厂在处理矿井尾水时出现了“翻池”现象,分析了产生“翻池”的原因,介绍了对原水进行混合、缓冲、稳流,增设流动电流与浊度双闭环加流量前馈控制的自动加药系统,投加助凝剂等一系列对策,以及达到的效果。

There occurred ＂sediment upturning＂ phenomenon in treatment of mine tail water in a mining water treatment plant, and the cause was analyzed. A number of countermeasures were introduced including mixing, buffering, and uniforming raw water flow, and setting up of automatic chemical feeding system with dual closed loop of stream current and turbidity and feedforward control of flow rate, as well as addition of coagulant aids. The effectiveness after taking these measures was also introduced.
