Overview
Shanxi wastewater treatment plant serves Yangcun Township in Hejin City, Yuncheng, Shanxi Province, China, with a population of 89,000. It operates under China's national wastewater standards.
The Shanxi wastewater treatment plant is located in Yangcun Township, Hejin City, within Yuncheng Prefecture, Shanxi Province, China. It serves a population of approximately 89,000 people, classifying it as a medium-sized municipal facility under Chinese wastewater management frameworks. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent likely discharges into a local river or stream within the Yellow River basin, as the facility is inland and over 50 km from the coast. The Yellow River system supports extensive agriculture and provides water for millions, making proper treatment critical for downstream water quality and ecosystem health.
Environmental context
The plant is situated in the Yellow River basin, one of China's most important water systems. Treated wastewater likely enters a tributary of the Yellow River, which flows through arid and semi-arid regions before reaching the Bohai Sea. The river supports irrigation, industry, and domestic use, and its waters are subject to eutrophication risks from nutrient loads. Effective treatment helps protect downstream aquatic life and water quality for communities.
