Overview
Ningxia Hui wastewater treatment plant serves Dawukou District in Shizuishan, Ningxia, China, with a population of 348,000. The plant operates under China's national wastewater standards.
Ningxia Hui wastewater treatment plant is located in Changxing Subdistrict, Dawukou District, Shizuishan City, Ningxia Hui Autonomous Region, China. It serves a population of approximately 348,000 people, classifying it as a large-scale municipal facility within the region's wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water's sensitivity. For large agglomerations like this, advanced treatment (Class 1A) is typically required to protect water quality, especially in water-scarce regions like Ningxia. The plant's treated effluent likely discharges into local water bodies that eventually drain into the Yellow River basin, a critical water source for northern China. The region's arid climate and heavy industrial activity make effective wastewater treatment essential for protecting downstream ecosystems and supporting water reuse for agriculture and industry.
Environmental context
The plant is located in the Yellow River basin, a vital waterway that supports agriculture, industry, and millions of people across northern China. The local watershed faces challenges from water scarcity and pollution, making treated wastewater a key resource for environmental flow maintenance and irrigation. Downstream, the Yellow River flows into the Bohai Sea, a semi-enclosed sea with significant ecological and economic importance.
