Overview
Anhui wastewater treatment plant serves 190,000 people in Dangshan County, Suzhou, Anhui Province, China. The facility operates under China's national wastewater discharge standards.
The Anhui wastewater treatment plant is located on Yanxi Road in Dangshan County, Suzhou City, Anhui Province, China. It serves a population of approximately 190,000, placing it in the medium-to-large agglomeration category for the region. As a municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The treated effluent is discharged into local waterways that ultimately drain into the Huai River basin, a major river system in eastern China. The Huai River flows eastward into Hongze Lake and eventually reaches the Yellow Sea. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this densely populated agricultural region.
Environmental context
The plant discharges into local tributaries of the Huai River basin, which flows through Anhui and Jiangsu provinces into Hongze Lake and then to the Yellow Sea. The watershed supports intensive agriculture and numerous communities, making nutrient and pathogen removal critical for preventing eutrophication and protecting downstream drinking water sources. The region experiences a monsoon climate with seasonal flooding, which can challenge treatment plant performance during wet weather.
