北方某开发区净水厂工艺设计问题探讨

Discussion on process design of the waterworks in a development zone in Northern China

针对某净水厂实际处理能力不能满足设计要求、矾花大量上浮、臭氧接触池池顶冒水等问题,通过分析比对找到原因,例如沉淀池配水区过孔流速较大、滤池承托层级配问题以及厚度不足等,并提出了解决措施。

In view of the issues that the actual treatment capacity of a waterworks could not fit the design requirements,a large amount of alum floated up,water overflowed at the top of the ozone contact pool,the causes were found through analysis and comparison,such as the large through-hole velocity in the water distribution area of the sedimentation tank,the insufficient thickness of the filter supporting layer,etc.,and the solutions were put forward.
