Overview
The Jiangsu wastewater treatment plant serves Liyang City in Jiangsu Province, China, with a population equivalent of 32,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Liyang City, Jiangsu Province, China, serving a population equivalent of approximately 32,000. The facility is situated in the Yangtze River Delta region, an area with dense urban and industrial activity. As a municipal plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River and then the East China Sea. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Yangtze Delta region.
Environmental context
The plant discharges into the local water system within the Yangtze River basin, which flows into the East China Sea. The downstream environment includes the Yangtze River estuary, a critical habitat for migratory fish and aquatic biodiversity. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making effective treatment essential.
