Overview
Ningxia Hui wastewater treatment plant serves Jingyuan County in the Ningxia Hui Autonomous Region, China. It handles a population of 26,000 and discharges into local waterways.
Ningxia Hui wastewater treatment plant is located in Jingyuan County (泾源县), part of Guyuan City in the Ningxia Hui Autonomous Region, China. The facility serves approximately 26,000 residents, making it a medium-sized agglomeration under Chinese wastewater management standards. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment to meet pollutant limits for BOD, COD, and suspended solids. Regulatory expectations for this population tier generally mandate secondary biological treatment. The plant discharges treated effluent into local rivers that drain into the Yellow River basin, a critical water resource for northern China. The receiving water bodies support agricultural irrigation and downstream ecosystems, making proper treatment essential for water quality in the region.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which ultimately drains into the Bohai Sea. The Yellow River basin is a vital water source for agriculture and industry in northern China, and its ecological health is sensitive to nutrient loading and pollution. Proper wastewater treatment helps protect downstream aquatic habitats and supports water reuse for irrigation.
