郑州某水厂滤池过滤周期缩短原因分析及应对措施

Reasons and Countermeasures for Shortening of Filter Filtration Cycle in a Water Plant in Zhengzhou

针对郑州市某地表水厂冬季滤池过滤周期严重缩短的情况,对堵塞滤池的粘性物质做了定性分析。根据小试结论,在实际生产中实施了停用除藻剂、更换混凝剂、增加浊度、投放鲢鱼苗等措施,取得了很好的效果,使滤池恢复了正常生产。

A surface water plant in Zhengzhou City had a problem in severely shortening filter filtration cycle in winter. Therefore, a qualitative analysis of the viscous materials plugging the filter was performed. According to the conclusion from small-scale test, some measures such as stopping use of algaecide, changing coagulants, increasing turbidity and releasing silver carp fries were taken in the actual production. Good results were achieved, and the normal production of filter was recovered.
