Anhui Wastewater Treatment Plant, Gaohe Town, Anqing | China

The Anhui wastewater treatment plant is located in Gaohe Town, Huaining County, within the city of Anqing in Anhui Province, China. The facility serves a population of approximately 68,000 people, making it a medium-sized municipal treatment plant in the region. It is situated inland, more than 50 km from the coast, and its operations are part of the broader water management infrastructure for the Yangtze River basin. As a plant serving a population of 68,000, it falls under China's national wastewater discharge standards, which require secondary treatment for urban wastewater. Typical facilities of this scale in China employ biological treatment methods such as activated sludge to meet the Class 1A or 1B discharge standards set by the Ministry of Ecology and Environment. The plant is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The treated effluent from the plant is discharged into local waterways that ultimately flow into the Yangtze River, one of China's most important water bodies. The Yangtze River supports diverse aquatic ecosystems and provides water for millions of people. Proper treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream water quality and ecological health in the Yangtze River basin.

The plant discharges into local streams that drain into the Yangtze River, the longest river in Asia and a critical water resource for central and eastern China. The Yangtze River basin supports a wide range of aquatic life, including endangered species such as the Chinese sturgeon and the Yangtze finless porpoise. Effective wastewater treatment is essential to minimize eutrophication and contamination risks in this ecologically sensitive river system.
