Overview
Ningxia Hui wastewater treatment plant serves Yanchi County in Ningxia, China. It treats wastewater for approximately 26,400 residents under China's national discharge standards.
Ningxia Hui wastewater treatment plant is located in Yanchi County, Wuzhong City, Ningxia Hui Autonomous Region, China. The facility serves a population of approximately 26,400 people, placing it in the small-to-medium agglomeration category for Chinese municipal wastewater systems. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Yellow River basin, a critical water resource in northern China. The plant plays a key role in protecting downstream water quality in this arid region, where water reuse and pollution control are priorities.
Environmental context
The plant discharges into local streams that feed the Yellow River system, which flows through northern China and into the Bohai Sea. The Yellow River basin supports intensive agriculture and urban water supply, making effluent quality crucial. The region's semi-arid climate means water resources are scarce, and the plant helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication in downstream reservoirs and coastal waters.
