Overview
Ningxia Hui wastewater treatment plant serves Yinchuan, Ningxia, China, with a population of 132,000. It operates under China's national wastewater standards, ensuring treated effluent meets discharge requirements.
Ningxia Hui wastewater treatment plant is located in Yinchuan, the capital of Ningxia Hui Autonomous Region in northwest China. The plant serves a population of approximately 132,000, placing it in the medium-to-large agglomeration category. As part of China's rapidly expanding urban wastewater infrastructure, the facility plays a key role in protecting local water resources. China's wastewater treatment standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The plant is expected to meet Class 1A or 1B effluent limits, which include strict requirements for chemical oxygen demand, ammonia nitrogen, and total phosphorus. These standards align with China's broader Water Pollution Prevention and Control Action Plan. The plant discharges into the Yellow River basin, which is the primary water source for agriculture and domestic use in the region. The Yellow River flows through arid northern China before reaching the Bohai Sea. Protecting this river from nutrient pollution is critical for downstream ecosystems and human water supply. The plant's operation supports the ecological health of the Yellow River and its tributaries.
Environmental context
The plant discharges into the Yellow River basin, a major waterway that flows through Ningxia and ultimately reaches the Bohai Sea. The Yellow River is a vital water source for irrigation and drinking water in the region, and its ecological health is sensitive to nutrient loading from urban and agricultural runoff. The plant's treated effluent helps maintain water quality in this arid region, supporting aquatic life and downstream communities.
