Overview
Shanxi wastewater treatment plant serves Datong, Shanxi Province, China, with a population equivalent of 280,000. The facility operates under China's national wastewater discharge standards.
The Shanxi wastewater treatment plant is located in the Yungang District of Datong, Shanxi Province, China. It serves a population equivalent of 280,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, approximately 50 kilometers from the coast, and its treated effluent likely discharges into local waterways that eventually flow toward the Bohai Sea. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants serving populations over 100,000 are typically required to meet Class 1-A or 1-B standards, which mandate advanced treatment including biological nutrient removal. The plant's scale suggests it employs secondary or tertiary treatment to comply with national effluent limits. Given its location in the Shanxi Plateau, treated wastewater likely enters the Sanggan River system, a tributary of the Yongding River, which flows into the Hai River and ultimately the Bohai Sea. The downstream environment supports agricultural irrigation and urban water supply, making effective treatment critical for protecting water quality and aquatic ecosystems in the region.
Environmental context
The plant's treated effluent likely discharges into the Sanggan River, a tributary of the Yongding River within the Hai River basin. This watercourse flows through agricultural and urban areas before reaching the Bohai Sea, a semi-enclosed marginal sea with significant ecological and economic importance. The downstream environment supports diverse aquatic life and provides water for irrigation and industry, necessitating stringent nutrient and pollutant removal to prevent eutrophication and protect coastal ecosystems.
