Overview
The Shaanxi wastewater treatment plant serves Xunyi County in Xianyang, Shaanxi, China, treating wastewater for approximately 38,000 people. It operates under China's national wastewater regulations.
The Shaanxi wastewater treatment plant is located in Xunyi County, part of Xianyang City in Shaanxi Province, China. It serves a population of approximately 38,000 people, placing it in the small to medium agglomeration category for Chinese wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants serving populations around 38,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially if discharging into sensitive waters. The plant's treated effluent likely discharges into a local river or stream within the Wei River basin, which flows into the Yellow River (Huang He). The Yellow River is a major waterway in northern China, supporting agriculture, industry, and ecosystems. Proper treatment is essential to protect downstream water quality and aquatic life in this ecologically significant basin.
Environmental context
The plant is situated inland in Shaanxi Province, within the Wei River basin, a tributary of the Yellow River. The Yellow River is a critical water resource for northern China, supporting millions of people and diverse ecosystems. Downstream, the river flows through arid and semi-arid regions where water quality is vital for irrigation and drinking water. The plant's discharge must meet strict standards to prevent eutrophication and protect aquatic habitats in this sensitive watershed.
