Anhui Wastewater Treatment Plant, Lingbi County, Anhui Province, China

The Anhui wastewater treatment plant is located in Lingbi County, Suzhou City, Anhui Province, China. It serves a population of approximately 160,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for the region. As a facility serving over 100,000 people, the plant is expected to meet secondary or advanced treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national regulation sets effluent limits for organic matter, nutrients, and other pollutants, with stricter requirements for plants discharging into sensitive water bodies. It likely incorporates biological treatment to comply with these standards. The treated effluent from the plant is discharged into local water bodies within the Huai River basin, which ultimately flows into the East China Sea. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region's rivers and lakes. Its operation helps mitigate pollution from urban and industrial sources in the densely populated Anhui Province.

The plant discharges into the Huai River basin, a major watershed in eastern China that drains into the East China Sea. The Huai River and its tributaries support diverse aquatic life and provide water for agriculture and industry. Downstream ecosystems include wetlands and lakes that are important for migratory birds and fish. The plant's treatment performance directly affects water quality in these sensitive environments.
