Overview
Jiangsu wastewater treatment plant serves Rudong County, Jiangsu Province, China, with a population equivalent of 276,000. The facility has a designed capacity of 1.00 unit and is located inland, discharging into local waterways.
The Jiangsu wastewater treatment plant is located in Rudong County (如东县), Nantong City, Jiangsu Province, China. It serves a population equivalent of 276,000, classifying it as a large agglomeration under Chinese wastewater regulations. The facility is situated inland, approximately 32.35°N, 121.15°E, and its operations are part of the regional water management infrastructure for the Yangtze River Delta area. As a large-scale plant in China, it is expected to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. Chinese regulations require secondary treatment as a minimum for municipal plants, with tertiary treatment often mandated in sensitive watersheds. The designed capacity of 1. The plant discharges treated wastewater into local rivers that ultimately drain into the Yellow Sea via the Yangtze River estuary or nearby coastal waters. The receiving water bodies support diverse aquatic life and are important for regional fisheries and agriculture. Effective treatment is critical to prevent eutrophication and protect downstream ecosystems, including the Yangtze River Delta's ecologically sensitive wetlands.
Environmental context
The plant's treated effluent flows into local rivers within the Yangtze River basin, eventually reaching the Yellow Sea. The downstream environment includes estuarine and coastal habitats that support migratory birds, fish, and other aquatic species. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in coastal zones, making advanced treatment important for maintaining water quality in this densely populated and economically active region.
Frequently asked questions
The plant is located in Rudong County (如东县), Nantong City, Jiangsu Province, China, at coordinates 32.35°N, 121.15°E.
The plant serves a population equivalent of 276,000, classifying it as a large agglomeration under Chinese wastewater regulations.
Treated wastewater is discharged into local rivers that flow into the Yangtze River estuary and eventually the Yellow Sea, supporting downstream aquatic ecosystems.
The plant operates under China's Environmental Protection Law and Water Pollution Prevention and Control Law, which mandate secondary treatment as a minimum for municipal plants, with stricter standards in sensitive areas.
For large agglomerations in China, secondary treatment (e. g. , activated sludge) is standard, with tertiary treatment increasingly required in ecologically sensitive watersheds to reduce nutrients and protect receiving waters.
