Overview
Ningxia Hui wastewater treatment plant serves Shizuishan in Ningxia, China, with a population of 80,000. The facility is located inland, discharging into local waterways.
Ningxia Hui wastewater treatment plant is located in Pingluo County, Shizuishan City, Ningxia Hui Autonomous Region, China. It serves an estimated population of 80,000 people, placing it in the medium agglomeration category under Chinese wastewater regulations. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban facilities of this scale. Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for COD, BOD, ammonia nitrogen, and other pollutants. The treated effluent is discharged into local rivers that drain into the Yellow River basin, a critical water resource for northern China. The region's semi-arid climate makes water quality management essential for downstream agricultural and ecological uses. The plant's operation supports the protection of the Yellow River's water quality and the broader ecological health of the Ningxia region.
Environmental context
The plant discharges into local waterways that ultimately flow into the Yellow River, the second-longest river in China. The Yellow River basin supports extensive agriculture and provides drinking water for millions. The Ningxia region is semi-arid, making water reuse and pollution control critical. The plant's effluent must meet strict standards to protect downstream ecosystems and water users.
