Project Scale: 

10,000 m³/d

Project Introduction:

The project is located on the northwest side of the intersection of Zaiyuan Avenue and Shanyuan Road in Gaogou Town, Lianshui County, with a total land area of 15,415 square meters and a total construction area of 2,081.8 square meters. A new sewage treatment plant has been built with a total investment of 60 million yuan, and construction began in August 2022. The sewage treatment process adopts the "air flotation tank + inverted A2O biochemical tank + high-efficiency sedimentation + biological aerated filter + cloth media filter" process: sludge treatment adopts the "sludge thickening + sludge conditioning + high-pressure diaphragm plate and frame filter press" dehydration process, with a sludge moisture content of ≤60%; disinfection adopts the "sodium hypochlorite" process; deodorization adopts the "chemical scrubbing + bio-soil" process. The effluent water quality meets discharge standards (COD, ammonia nitrogen, and TP in the effluent follow the Class IV water quality standards in the "Environmental Quality Standards for Surface Water" (GB3838-2002), and other factors follow the Class 1A discharge standards in the "Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant" (GB18918-2002)). The commissioned operation period is 5 years.
