Overview
Shaanxi wastewater treatment plant serves 62,000 people in Yanta District, Xi'an, China. It operates under China's national wastewater standards for urban agglomerations.
The Shaanxi wastewater treatment plant is located in Yanta District, Xi'an, Shaanxi Province, China, serving a population of approximately 62,000. The facility is situated in the software park area of Xi'an, a major inland city in central China. As a medium-sized agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for urban plants. The regulatory framework under China's Water Pollution Prevention and Control Law requires such facilities to achieve Class 1A or 1B effluent standards depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into the Wei River system, a tributary of the Yellow River, which ultimately flows into the Bohai Sea. The Wei River basin supports agricultural irrigation and urban water supply, making effective treatment critical for downstream water quality and ecosystem health.
Environmental context
The plant discharges into the Wei River, a major tributary of the Yellow River, which flows eastward through Shaanxi and into the Bohai Sea. The Wei River basin is heavily utilized for agriculture and urban water supply, and its ecological health is sensitive to nutrient loading and industrial pollutants. Downstream ecosystems, including wetlands and fisheries in the Yellow River delta, depend on maintained water quality from upstream treatment facilities.
