Overview
Shanxi wastewater treatment plant serves Sunjiazhuang Town in Yangquan, Shanxi, China. It treats wastewater for approximately 67,000 people as part of the region's municipal infrastructure.
The Shanxi wastewater treatment plant is located in Sunjiazhuang Town, Yuxian County, within the city of Yangquan, Shanxi Province, China. The facility serves a population of approximately 67,000, placing it in the medium agglomeration category for Chinese wastewater systems. As a plant in China, it operates under national wastewater discharge standards, which typically require secondary treatment for urban wastewater. For a facility serving this population size, compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) is expected, with effluent limits tailored to the receiving environment. The plant discharges treated effluent into local watercourses that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The facility plays a key role in protecting downstream water quality in a region characterized by coal mining and industrial activity, supporting both ecological health and water reuse potential.
Environmental context
The plant's treated effluent enters local streams within the Hai River basin, which flows eastward through Hebei Province and Tianjin before discharging into the Bohai Sea. This coastal sea is ecologically important for fisheries and migratory species. The watershed faces pressures from industrial and agricultural runoff, making effective nutrient removal critical to prevent eutrophication in downstream waters.
