Overview
Xinjiang Uygur wastewater treatment plant serves Hejing County in Xinjiang, China, with a population of 68,200. The plant operates under China's national wastewater discharge standards.
The Xinjiang Uygur wastewater treatment plant is located in Hejing County (和静县), within the Bayingolin Mongol Autonomous Prefecture of Xinjiang, China. It serves an estimated population of 68,200 residents in the county seat and surrounding areas. The plant is situated in an arid inland region at the foot of the Tianshan Mountains, where water resources are scarce and treatment plays a critical role in protecting local water quality. China's wastewater treatment regulations require secondary treatment for urban plants serving populations over 50,000, with discharge standards set by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Plants of this scale typically employ biological treatment processes such as activated sludge or sequencing batch reactors to meet Class 1A or 1B effluent limits, depending on the sensitivity of the receiving water body. The treated effluent from this plant likely discharges into local rivers or irrigation channels that drain into the Tarim River basin, the largest inland river basin in China. The Tarim River eventually terminates in the Taitema Lake, an ecologically sensitive terminal lake in the Taklamakan Desert. Proper treatment is essential to prevent nutrient pollution and salinization in this arid ecosystem, which supports riparian forests and migratory bird habitats.
Environmental context
The plant is located in the Tarim River basin, the largest inland river system in China. Treated wastewater likely flows into local streams that feed the Tarim River, which ends at Taitema Lake in the Taklamakan Desert. This terminal lake is a critical habitat for migratory birds and supports fragile desert riparian ecosystems. Effective treatment is vital to prevent eutrophication and salinization in this water-scarce region.
Frequently asked questions
The plant is located in Hejing County (和静县), Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region, China. It serves the county seat and surrounding communities.
The plant serves approximately 68,200 people, classifying it as a medium-sized urban wastewater treatment facility under Chinese standards.
The plant protects local streams and the Tarim River basin, the largest inland river system in China. The Tarim River flows into Taitema Lake, an ecologically important terminal lake in the Taklamakan Desert.
The plant operates under China's national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving over 50,000 people, secondary treatment is required, with effluent limits typically set at Class 1A or 1B depending on the receiving water body's sensitivity.
Plants of this scale in China commonly use biological treatment processes such as activated sludge, oxidation ditches, or sequencing batch reactors. These systems achieve secondary treatment standards, removing organic matter and nutrients to meet national discharge limits.
