Overview
Shaanxi wastewater treatment plant serves Meixian County in Shaanxi Province, China, with a population of 68,200. It operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Sanzhai Village, Shoujie Subdistrict, Meixian County, Shaanxi Province, China. It serves a population of approximately 68,200 people, making it a medium-sized municipal facility in the region. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant discharges treated wastewater into local waterways that eventually drain into the Wei River, a major tributary of the Yellow River. This downstream connection highlights the plant's role in protecting water quality in the Yellow River basin, which supports agriculture, industry, and ecosystems in northern China.
Environmental context
The plant's treated effluent flows into the Wei River system, which is a key tributary of the Yellow River. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for irrigation and domestic use across several provinces. Protecting this watershed from nutrient pollution and pathogens is critical for maintaining downstream water quality and ecosystem health.
