Overview
Ningxia Hui wastewater treatment plant serves 74,000 people in Yinchuan, Ningxia, China. It operates under national wastewater standards for inland facilities.
Ningxia Hui wastewater treatment plant is located in Yinchuan, the capital of Ningxia Hui Autonomous Region in northwestern China. The facility serves a population of approximately 74,000 residents in the urban area, contributing to the region's sanitation infrastructure. As a plant serving a medium-sized agglomeration, it is expected to meet China's national discharge standards for municipal wastewater, which typically require secondary treatment or higher. Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a critical water resource for northern China. The region's semi-arid climate makes water quality management particularly important for downstream agricultural and ecological uses.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which is the primary water source for irrigation and drinking water in the arid Ningxia region. Downstream, the Yellow River supports diverse aquatic life and provides water for wetlands along its course. The plant's operations are crucial for protecting the river from nutrient pollution and maintaining water quality for the surrounding agricultural landscape.
