Anhui Wastewater Treatment Plant, Wucheng Town, Anhui Province

The Anhui wastewater treatment plant is located in Wucheng Town, Wuwei City, within Anhui Province, China. It serves a population of approximately 288,000 people, classifying it as a large-scale municipal facility. The plant is situated in the Yangtze River basin, which is a major economic and ecological region in China. As a large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which requires secondary treatment with nutrient removal for plants of this scale. The designed capacity is 1. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River, one of the world's longest rivers and a critical freshwater resource. The downstream environment supports diverse aquatic life and provides water for agriculture, industry, and drinking water for millions. Proper treatment is essential to protect water quality in this densely populated and economically vital region.

The plant is located in the Yangtze River basin, with treated effluent flowing into tributaries that feed into the Yangtze River. The Yangtze River is a vital ecological corridor supporting numerous fish species, including the endangered Chinese sturgeon, and provides water for irrigation and municipal use. The plant's discharge must comply with national standards to prevent eutrophication and protect downstream ecosystems.
