Anhui Wastewater Treatment Plant, Shou County, Anhui, China

The Anhui wastewater treatment plant is located in Shou County, Anhui Province, China, serving a population of approximately 182,000. The facility is part of the municipal infrastructure for the county seat of Shou Chun Town, within the Huainan prefecture-level city. As a medium-to-large agglomeration, the plant plays a key role in managing domestic wastewater for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment, with more stringent nutrient removal in sensitive watersheds. The plant's scale suggests it likely employs conventional activated sludge or similar biological treatment to meet regulatory requirements. The plant discharges treated effluent into local waterways that ultimately drain into the Huai River basin, a major tributary of the Yangtze River system. The Huai River is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment at this facility helps protect downstream water quality and the broader Yangtze ecosystem.

The plant's treated effluent flows into local streams that are part of the Huai River basin, which drains into the Yangtze River and eventually the East China Sea. The Huai River watershed supports important fisheries and agricultural irrigation, making nutrient and pollutant control critical. The region experiences a subtropical monsoon climate with seasonal flooding, so consistent treatment performance is essential to prevent algal blooms and protect downstream aquatic habitats.
