Overview
Shaanxi wastewater treatment plant serves Yuyang District, Yulin City, Shaanxi Province, China, with a population equivalent of 250,000. It operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Yuyang District, Yulin City, Shaanxi Province, China. It serves a population equivalent of 250,000, classifying it as a large-scale municipal facility within the region. The plant is situated inland, approximately 50 kilometers from the coast, and its operations are integral to local water management. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive areas. Regulatory requirements for plants of this scale typically include biological treatment and disinfection to protect receiving waters. The plant discharges treated effluent into local water bodies that ultimately drain into the Yellow River basin, a major river system in northern China. The downstream environment supports agricultural irrigation and aquatic ecosystems, making effective treatment crucial for preventing eutrophication and safeguarding water quality.
Environmental context
The plant's treated effluent flows into tributaries of the Yellow River, which traverses northern China before emptying into the Bohai Sea. The Yellow River basin is ecologically sensitive, supporting diverse aquatic life and providing water for irrigation and industry. Effective nutrient removal is essential to prevent algal blooms and maintain the health of downstream wetlands and coastal zones.
