Anhui Wastewater Treatment Plant, Huangshan, Anhui Province, China

The Anhui wastewater treatment plant is located in Tunxi District, Huangshan City, Anhui Province, China. It serves a population of approximately 62,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For a facility serving around 62,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into local waterways that eventually flow into the Xin'an River system, which drains into Qiandao Lake (Lake Thousand Island) and ultimately into the East China Sea. This watershed supports diverse aquatic life and provides water resources for downstream communities and ecosystems.

The plant discharges into the Xin'an River basin, which flows into Qiandao Lake, a large reservoir in Zhejiang Province, before reaching the East China Sea. The downstream environment includes ecologically sensitive areas that support fisheries and biodiversity. Proper treatment is essential to prevent eutrophication in Qiandao Lake and maintain water quality for downstream users.
