Anhui Wastewater Treatment Plant, Fengyang County, Chuzhou, Anhui Province

The Anhui wastewater treatment plant is located in Fengyang County, part of Chuzhou City in Anhui Province, China. It serves a population of approximately 142,000 people, making it a medium-to-large agglomeration under typical Chinese municipal wastewater classification. The plant is situated in the inland region of eastern China, contributing to local water management. As a municipal facility serving over 100,000 people, the plant is expected to meet secondary treatment standards under China's national wastewater discharge regulations (GB 18918-2002). Chinese law requires urban wastewater treatment plants to achieve at least secondary treatment, with stricter standards for plants discharging into sensitive water bodies. The plant's operational details align with the country's ongoing efforts to improve water quality through the Water Pollution Prevention and Control Action Plan. The plant discharges treated effluent into local waterways that ultimately drain into the Huai River basin, a major tributary of the Yangtze River system. The Huai River watershed supports extensive agricultural activity and provides drinking water for millions. Proper treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream aquatic ecosystems and water quality for communities along the river.

The plant's treated effluent flows into local streams that are part of the Huai River basin, which drains into the Yangtze River and eventually the East China Sea. The Huai River watershed is ecologically important, supporting diverse freshwater species and providing irrigation for surrounding farmland. Effective wastewater treatment here helps mitigate eutrophication risks and protects downstream water quality in this densely populated agricultural region.
