四川某污水处理厂提标改造及扩建工程设计

Design of Upgrading Reconstruction and Expansion Project of a Wastewater Treatment Plant in Sichuan Province

介绍了四川省某污水处理厂提标改造及扩建工程的改扩建设计思路,主要新增改良型卡鲁塞尔氧化沟1座、配水井1座、纤维转盘滤池1座,使处理规模增加至2×10;m;/d,且出水水质达到一级A排放标准,并针对一期工程运行及设备实际存在的问题,在二期扩建工程设计时采取了改进措施,实现了提标改造和扩建工程的协调统一,为同类型污水厂的提标扩建设计提供参考。

The design idea of upgrading reconstruction and expansion project of a sewage treatment plant in Sichuan Province was introduced.In order to increase the treatment scale to 2×10~4m~3/d,the main structures including a modified carrousel oxidation ditch,a water distribution well and a fiber turntable filter were to be built,and effluent quality would meet GradeⅠ-A standard.There existed some practical problems in the operation and equipment of the first phase of the sewage treatment plant.Improvement measures were taken in the design of the second phase expansion project,to realize upgrading reconstruction and expansion simultaneously.This paper provided reference for the upgrading and expansion design of similar sewage treatment plants.
