Shanxi Wastewater Treatment Plant, Xiangyuan County, Shanxi, China

The Shanxi wastewater treatment plant is located in Xiangyuan County, Changzhi City, Shanxi Province, China. It serves a population of approximately 63,000, classifying it as a medium-sized municipal facility within the region's water management infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a facility serving this population, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The downstream environment supports agricultural irrigation and ecological flows, making effective treatment crucial for water quality and regional water security.

The plant discharges into local tributaries of the Yellow River basin, which flows through northern China and empties into the Bohai Sea. The watershed supports agricultural activities and provides habitat for aquatic species. Proper treatment is essential to prevent nutrient pollution and protect downstream water quality in this semi-arid region.
