| Abstract: | The design and construction scale of a sewage treatment plant in the reservoir area is30,000 m~3/d. According to the characteristics of sewage and the requirements for raising the standard, the treatment process of the project adopts: A/A/O +MBR process, sludge treatment adopts mechanical concentration dehydration process, and odor gas adopts biological filtration process. This paper introduces in detail the water quality and extraction process and main design parameters of the inlet and outlet water,and the effluent quality finally meets the Grade A standard in the Pollutant Discharge Standard for Urban Sewage Treatment Plants( GB 18918-2002). This relevant experience can be used for reference in similar projects. |
