Overview
The Shaanxi wastewater treatment plant serves Lintong District, Xi'an, China, with a population equivalent of 192,000. It operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Lintong District, Xi'an, Shaanxi Province, China. It serves a population of approximately 192,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The plant's treatment processes are designed to meet these national standards, ensuring compliance with environmental protection requirements. The treated effluent is discharged into local water bodies that ultimately drain into the Wei River, a major tributary of the Yellow River. The plant plays a crucial role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Guanzhong Plain.
Environmental context
The plant's discharge enters the local drainage network, which flows into the Wei River and eventually the Yellow River, China's second-longest river. The Yellow River basin supports diverse aquatic life and provides water for agriculture and industry. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream water quality and ecological health.
