Overview
The Shaanxi wastewater treatment plant serves Tongchuan City in Shaanxi Province, China, with a population equivalent of 181,100. It operates under China's national wastewater regulations.
The Shaanxi wastewater treatment plant is located in Tongchuan City, Shaanxi Province, China, serving a population of approximately 181,100. The plant is situated in the Wangyi District, along Zhongxing Dyke, and plays a key role in managing municipal wastewater for this inland urban area. As a facility serving a medium-to-large agglomeration, the plant is expected to meet China's national discharge standards, which require secondary treatment as a minimum for urban wastewater. China's Water Pollution Prevention and Control Action Plan and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) set stringent limits for effluent quality, particularly for nutrients and organic matter. The plant's treated effluent is discharged into local water bodies that ultimately drain into the Yellow River basin, a critical water resource for northern China. The surrounding region is semi-arid, making water quality protection essential for downstream agricultural and domestic water uses. The plant's operation supports the ecological health of the Wei River system, a major tributary of the Yellow River.
Environmental context
The plant discharges into local waterways that flow into the Wei River, a major tributary of the Yellow River. The Yellow River basin is ecologically sensitive, supporting diverse aquatic life and providing water for millions of people. Effective treatment is crucial to prevent eutrophication and protect downstream water quality in this water-scarce region.
