Shanxi Wastewater Treatment Plant, Xincheng Town, Shanxi Province, China

The Shanxi wastewater treatment plant is located in Xincheng Town, Xiangfen County, within Linfen City, Shanxi Province, China. The facility serves a population of approximately 66,000 residents, placing it in the medium-scale category for municipal wastewater treatment in the region. As a Chinese municipal wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent quality requirements based on the receiving water body's sensitivity. For inland plants like this one, Grade 1-A or 1-B standards typically apply, requiring biological treatment with nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The facility plays a key role in protecting downstream water quality and supporting the ecological health of the Fen River, a tributary of the Yellow River that flows through Shanxi Province.

The plant's treated effluent flows into the Fen River, a major tributary of the Yellow River, which ultimately drains into the Bohai Sea. The Fen River watershed supports diverse aquatic life and provides water for agriculture and industry in Shanxi Province. The plant's operations help reduce nutrient and pollutant loads entering this ecologically important river system.
