Anhui Wastewater Treatment Plant, Changfeng County, Anhui, China

The Anhui wastewater treatment plant is located in Shuihu Town, Changfeng County, Hefei City, Anhui Province, China. It serves a population of approximately 63,000 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving a medium-sized urban population, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This national regulation sets effluent limits for conventional pollutants and nutrients, with more stringent requirements for plants discharging into sensitive water bodies. The treated effluent from the plant ultimately flows into the Yangtze River basin via local waterways, contributing to the protection of downstream aquatic ecosystems. The plant plays a key role in reducing pollution loads in the region, supporting water quality goals for the Huai River system and the broader Yangtze River Delta.

The plant discharges into local waterways that are part of the Huai River basin, which eventually drains into the Yangtze River and the East China Sea. The region supports diverse aquatic life and is important for migratory fish species. The plant's operation helps mitigate nutrient and pollutant loads that could otherwise impact downstream water quality and ecological health.
