Overview
Xinjiang Uygur wastewater treatment plant serves approximately 350,000 people in Urumqi, Xinjiang, China. It operates under China's national wastewater discharge standards.
The Xinjiang Uygur wastewater treatment plant is located in Urumqi, the capital of Xinjiang Uygur Autonomous Region in northwestern China. It serves a population of approximately 350,000, classifying it as a large-scale municipal facility within the region's urban wastewater infrastructure. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For plants of this scale, secondary treatment with nutrient removal is typically required, and advanced treatment may be mandated for discharge into sensitive water bodies. The plant's treated effluent is discharged into the local water system, which ultimately drains into the arid inland basins of Xinjiang. The region's water resources are critically important for agriculture and ecosystem health, making effective wastewater treatment essential for protecting downstream water quality and supporting sustainable development in this water-scarce area.
Environmental context
The plant discharges into the Urumqi River system, which flows through the city and eventually dissipates into the arid Tarim Basin or evaporates in the Gobi Desert. This inland basin is ecologically sensitive, supporting sparse but unique desert and oasis ecosystems. Proper treatment is vital to prevent contamination of groundwater and surface water used for irrigation and drinking in this water-stressed region.
Frequently asked questions
The plant is located in Urumqi, the capital of Xinjiang Uygur Autonomous Region in northwestern China, specifically in the Midong District near the Tu-Wu-Da Expressway.
The plant serves approximately 350,000 people, making it a large-scale municipal wastewater treatment facility in the Urumqi metropolitan area.
The treated effluent is discharged into the local Urumqi River system, which flows through the city and eventually drains into the arid inland basins of Xinjiang, such as the Tarim Basin.
The plant must comply with China's national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits on pollutants like COD, BOD, and nutrients. For large plants serving over 100,000 people, secondary treatment with nutrient removal is typically required.
For a plant of this scale in China, secondary biological treatment (e. g. , activated sludge) with nutrient removal is standard. In environmentally sensitive areas, advanced treatment such as tertiary filtration or disinfection may be mandated to meet stricter effluent standards.
