Ningxia Hui Wastewater Treatment Plant, Dawukou District, Shizuishan, Ningxia

Ningxia Hui wastewater treatment plant is located in Changsheng Street, Dawukou District, Shizuishan City, Ningxia Hui Autonomous Region, China. The plant serves an estimated population of 320,000, placing it in the large agglomeration category under Chinese wastewater regulations. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant likely employs biological treatment processes such as activated sludge or A2O to achieve compliance. The treated effluent is discharged into local water bodies within the Yellow River basin, which ultimately flows into the Bohai Sea. The plant plays a critical role in protecting the region's water quality and supporting downstream ecological health.

The plant discharges into the Yellow River basin, a major waterway in northern China that flows through arid and semi-arid regions before reaching the Bohai Sea. The downstream environment includes agricultural areas and ecologically sensitive wetlands that depend on adequate water quality. Effective treatment helps prevent eutrophication and protects aquatic biodiversity in the river and coastal zone.
