污水处理厂提标改造工程设计应注意的几个问题——以上海市某污水处理厂工程为例

摘要

A sewage treatment plant has been built a project size of 10 000 m3/d in Shanghai.With the development of the region,the amount of urban sewage also increased.Meanwhile,due to the improvement of emission standards,the plant,sludge treatment and disposal should be upgraded in the sewage treatment processcombined with the current situation of operation.In order to keepthe sewage plant working stably and reliably in the future,so that the water quality in line with the "Pollutant Discharge Standard of Municipal Wastewater Treatment Plant " (GB 18918-2002) level A standard.This paper takes the project as an example to analyze several problems that should be paid attention to in the upgrading design of sewage treatment plant.%上海市某污水处理厂已建一期工程规模为1万m3/d,随着地区的发展,城镇污水量也随着增大,同时,由于排放标准提高,并结合现状运行问题,该厂需在污水处理工艺、污泥处理与处置等方面进行提标改造,以便于污水厂今后能稳定、可靠地运行,使出水水质符合《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准.本文以该工程为例,分析污水处理厂在提标改造设计中应注意的几个问题.
