无锡市锡山区污水处理厂分厂提标改造方案研究

摘要:

锡山区污水处理厂经过4期改造,如今出水水质无法满足新标准的排放要求。本期工程在分厂处理能力的基础上进行,不扩容仅提标改造。预处理工艺采用应急池及缓冲池与中格栅及浅层气浮池,深度处理工艺采用臭氧催化氧化池、硝化滤池及滤布滤池与反硝化滤池,介绍了各单体的工艺设计。本工程于2019年9月建成,至今运行效果满足排放要求。

Abstract:

The Xishan District Sewage Treatment Plant has undergone four-phase renovation, and now the quality of the effluent cannot meet the discharge requirements of the new standard. The current phase of the project is carried out on the basis of the processing capacity of the branch, and only upgrading and renovation will be carried out without capacity expansion. The pretreatment process adopts emergency tank and buffer tank, middle grid and shallow air flotation tank, and the advanced treatment process adopts ozone catalytic oxidation tank, nitrification filter tank, filter cloth filter tank and denitrification filter tank. The process design of each monomer is introduced. . The project was completed in September 2019, and the operation effect always meets the emission requirements.
