Construction and operation of a large-scale precast sewage treatment system in Xining
To alleviate the problem of insufficient sewage treatment capacity, Xining City has built a new sewage treatment plant with a processing capacity of 100000 m3/d.
The factory adopts the “pretreatment+A2O-A+MBR+disinfection” treatment process, covering an area of 2.
93 hm2, and only takes 88 days to complete the water supply.
The effluent quality meets the Class A standard of the “Pollutant Discharge Standards for Urban Sewage Treatment Plants” (GB 18918-2002), and the operating cost is 1.
16 yuan/m3.
The precast construction method, treatment process, and cost analysis of the factory can provide reference for the construction and operation of large-scale precast sewage treatment plants.
