Overview
Shaanxi wastewater treatment plant serves 35,000 people in Weinan, Shaanxi, China. It discharges into the Wei River basin, a tributary of the Yellow River.
The Shaanxi wastewater treatment plant is located in Weinan City, Shaanxi Province, China, serving a population of approximately 35,000. Situated in the Linwei District, the plant is part of the municipal infrastructure for this inland urban area. As a medium-sized agglomeration, the plant is subject to China's national wastewater discharge standards, which require secondary treatment as a baseline for urban facilities. China's wastewater treatment regulations, under the Environmental Protection Law and the Water Pollution Prevention and Control Law, mandate that municipal plants meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving populations between 10,000 and 100,000, secondary treatment with nutrient removal is typically expected, especially in sensitive watersheds. The plant's operational details, including treatment process and capacity, are managed by local authorities to comply with these standards. The treated effluent from the Shaanxi plant is discharged into the local water system, which flows into the Wei River, a major tributary of the Yellow River. The Wei River basin supports agricultural irrigation and provides water for downstream communities. The Yellow River, as China's second-longest river, is ecologically significant, hosting diverse aquatic life and serving as a critical water source for northern China. Proper treatment helps protect this vital river system from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Wei River, a tributary of the Yellow River, which ultimately flows into the Bohai Sea. The Wei River basin is an important agricultural region, and the Yellow River supports a unique ecosystem, including migratory fish species and wetland habitats. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality for downstream uses.
