Overview
Xinjiang Uygur wastewater treatment plant serves 95,400 people in Yarkant County, Xinjiang, China. It operates under China's national wastewater standards for inland communities.
The Xinjiang Uygur wastewater treatment plant is located in Yarkant County (Yerqiang Subdistrict), within the Kashgar Prefecture of the Xinjiang Uyghur Autonomous Region, China. The facility serves a population of approximately 95,400, placing it in the medium-to-large agglomeration category for the region. As a Chinese municipal wastewater plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For inland plants like this one, Grade 1-A or 1-B standards typically apply, requiring biological treatment with nutrient removal. Facilities of this scale in China commonly employ activated sludge or similar secondary treatment technologies. The plant discharges into the local watershed, which ultimately drains into the Tarim River basin, the largest inland river system in China. The Tarim River flows through the Taklamakan Desert and terminates at Taitema Lake, supporting fragile desert ecosystems and agricultural irrigation. Proper wastewater treatment is critical to prevent pollution in this arid region where water resources are scarce and ecological balance is delicate.
Environmental context
The plant is located in the Tarim River basin, an endorheic system that terminates at Taitema Lake in the Taklamakan Desert. The receiving waters support irrigated agriculture and desert riparian ecosystems, including poplar forests that are ecologically sensitive to pollution and salinization. Downstream, the river's flow sustains migratory birds and endemic fish species. Effective treatment helps maintain water quality in this arid region where dilution capacity is limited.
Frequently asked questions
The plant is located in Yerqiang Subdistrict (Yarkant County), within Kashgar Prefecture, Xinjiang Uyghur Autonomous Region, China.
The plant serves approximately 95,400 people, classifying it as a medium-to-large agglomeration in the region.
The plant discharges into the Tarim River basin, an inland river system that supports agriculture and desert ecosystems in Xinjiang.
The plant operates under China's GB 18918-2002 standard, which mandates treatment levels based on the sensitivity of the receiving water body. Inland plants typically require Grade 1-A or 1-B standards with biological treatment and nutrient removal.
For agglomerations of this size, Chinese regulations generally require secondary biological treatment, often using activated sludge processes, with additional nutrient removal if discharging into sensitive waters.
