Overview
Ningxia Hui wastewater treatment plant serves Hongsibao District in Ningxia, China, with a population of 16,700. The facility operates under Chinese national wastewater standards.
Ningxia Hui wastewater treatment plant is located in Hongsibao District, Wuzhong City, Ningxia Hui Autonomous Region, China. The plant serves a population of approximately 16,700, classifying it as a small to medium-scale facility within the region's municipal infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate specific treatment levels based on receiving water body sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially in water-scarce regions like Ningxia. The plant discharges into local water bodies that ultimately drain into the Yellow River basin, a critical water resource for northern China. The region's arid climate and intensive agriculture make proper wastewater treatment essential for protecting downstream water quality and supporting local ecosystems.
Environmental context
The plant's treated effluent flows into local waterways within the Yellow River basin, which is the primary water source for agriculture and domestic use in northern China. The downstream environment includes ecologically sensitive areas that support diverse aquatic life and migratory birds. Proper treatment is crucial to prevent nutrient pollution and maintain water quality in this water-scarce region.
