Overview
The Anhui wastewater treatment plant serves approximately 30,000 people in Shitai County, Chizhou City, Anhui Province, China. It operates under China's national wastewater discharge standards.
The Anhui wastewater treatment plant is located in Renli Town, Shitai County, Chizhou City, in the mountainous region of southern Anhui Province, China. It serves a population of approximately 30,000 residents, classifying it as a small to medium-sized municipal facility within the local urban wastewater 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 based on the receiving water body's sensitivity. For plants serving populations around 30,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially if discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river within the Yangtze River basin, as Anhui Province drains into the Yangtze. The downstream environment includes the Yangtze River ecosystem, which supports diverse aquatic life and provides water for agriculture and drinking. Proper treatment is crucial to prevent eutrophication and protect water quality in this densely populated region.
Environmental context
The plant is located inland in the Yangtze River basin, over 50 km from the coast. Its treated effluent likely flows into a tributary of the Yangtze River, which ultimately reaches the East China Sea. The Yangtze River ecosystem is ecologically significant, supporting numerous fish species and providing critical habitat for migratory birds. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia in downstream lakes and coastal areas, making effective treatment essential for maintaining water quality and aquatic biodiversity.
