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

The Shanxi wastewater treatment plant is located in Daiyue Town, Shanyin County, within Shanxi Province, China. It serves an estimated population of 62,500 people, placing it in the medium-sized agglomeration category for the region. The plant is situated in a semi-arid inland area, where water resources are critical for local agriculture and ecosystems. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants serving populations over 50,000, secondary treatment with nutrient removal is typically required, especially if discharge is into sensitive water bodies. The plant's operational details are consistent with standard municipal infrastructure in Shanxi. The plant discharges into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The Yellow River supports extensive irrigation, industrial use, and domestic water supply for millions of people. Proper treatment at this plant helps protect downstream water quality and aquatic habitats in a region facing water scarcity and pollution challenges.

The plant's treated effluent flows into local streams that are part of the Yellow River basin, one of China's most important river systems. The Yellow River ultimately discharges into the Bohai Sea, a semi-enclosed sea with significant ecological and economic value. Downstream ecosystems include wetlands and riverine habitats that support migratory birds and fish species. In this arid region, maintaining water quality is crucial for both human use and biodiversity.
