Overview
Shaanxi wastewater treatment plant serves 220,000 people in Ganting Subdistrict, Xi'an, Shaanxi, China. It operates under China's national wastewater discharge standards for large agglomerations.
The Shaanxi wastewater treatment plant is located in Ganting Subdistrict, within the Hu District of Xi'an, Shaanxi Province, China. It serves a population of 220,000, classifying it as a large agglomeration under Chinese wastewater management regulations. The plant is situated in the inland region of central China, far from coastal areas. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which requires secondary treatment as a minimum, with tertiary treatment often mandated for plants discharging into sensitive water bodies. Regulatory compliance for this population tier typically involves activated sludge processes and nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The receiving water body supports agricultural irrigation and ecological flows, making proper treatment essential for protecting downstream water quality and aquatic habitats in the region.
Environmental context
The plant's treated effluent flows into the Wei River system, a tributary of the Yellow River, which eventually reaches the Bohai Sea. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper nutrient removal is critical to prevent eutrophication in downstream reservoirs and coastal zones.
