Overview
Qinghai wastewater treatment plant serves 140,000 people in Shangbaobao Village, Xining, Qinghai, China. It operates under China's national wastewater standards for large agglomerations.
The Qinghai wastewater treatment plant is located in Shangbaobao Village, Datong Hui and Tu Autonomous County, Xining, Qinghai Province, China. It serves a population of approximately 140,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the upper reaches of the Huangshui River basin, a tributary of the Yellow River. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which requires secondary treatment with nutrient removal for sensitive areas. Typical plants of this scale in China employ activated sludge processes with biological nitrogen and phosphorus removal. The plant discharges treated effluent into local watercourses that ultimately flow into the Huangshui River, a major tributary of the Yellow River. This river system supports agricultural irrigation and provides drinking water for downstream communities. The plant plays a critical role in protecting water quality in the Yellow River basin, which is ecologically significant for its biodiversity and as a water source for northern China.
Environmental context
The plant's treated effluent enters local streams that drain into the Huangshui River, a tributary of the upper Yellow River. The Yellow River basin is a vital water resource for northern China, supporting agriculture, industry, and domestic use. The region's semi-arid climate makes water quality management crucial for maintaining ecosystem health and preventing eutrophication in downstream reservoirs.
