Overview
Shaanxi wastewater treatment plant serves Xingping City in Shaanxi Province, China, with a population equivalent of 200,000. It operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Xingping City, within the Dongcheng subdistrict of Xianyang, Shaanxi Province, China. It serves a population of approximately 200,000 people, classifying it as a large-scale municipal facility 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. Typical facilities in this region employ activated sludge processes with biological nutrient removal to meet Class 1A or 1B standards. The plant discharges treated effluent into local waterways that ultimately drain into the Wei River, a major tributary of the Yellow River. The Wei River basin supports agricultural irrigation and industrial water use, and its ecological health is critical for downstream ecosystems in the Yellow River delta. Proper treatment helps protect water quality in this densely populated region.
Environmental context
The plant's treated effluent flows into the Wei River system, which joins the Yellow River downstream. The Yellow River basin is ecologically sensitive, supporting diverse aquatic life and providing water for millions of people. Nutrient pollution from urban wastewater can contribute to eutrophication in the river and its reservoirs, making effective treatment essential for maintaining water quality and ecosystem balance.
