Overview
Ningxia Hui wastewater treatment plant serves Yinchuan, Ningxia, China, treating wastewater for approximately 81,000 people. The plant operates under China's national wastewater discharge standards.
Ningxia Hui wastewater treatment plant is located in Yongning County, Yinchuan City, Ningxia Hui Autonomous Region, China. It serves a population of approximately 81,000 people, making it a medium-sized municipal facility in the region. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into a local river or canal within the Yellow River basin, as Yinchuan is situated near the Yellow River. The downstream environment supports agricultural irrigation and ecological flows in the arid Ningxia region, where water quality is critical for both human use and ecosystem health.
Environmental context
The plant is located in the Yellow River basin, approximately 50 km from the Yellow River mainstem. Treated wastewater likely enters a tributary or irrigation canal that eventually flows into the Yellow River, which is a major water source for northern China. The downstream environment includes agricultural areas and wetlands that depend on adequate water quality for irrigation and biodiversity. Protecting the Yellow River from nutrient pollution is a key environmental priority in the region.
