Jiangsu Wastewater Treatment Plant, Rudong County, Jiangsu, China

The Jiangsu wastewater treatment plant is located in Matang Town, Rudong County, Nantong City, Jiangsu Province, China. It serves a population of approximately 8,000 people, classifying it as a small-scale municipal facility. The plant is situated inland, more than 50 km from the coast, and its operations are governed by China's national wastewater discharge standards. The plant's designed capacity of 1.00 (likely in million cubic meters per day or similar unit) suggests a modest scale. Under Chinese regulations, small to medium-sized plants like this typically employ secondary biological treatment (e.g., activated sludge) to meet the national discharge standards (GB 18918-2002). The plant's performance is subject to local environmental protection bureau oversight. The treated effluent is discharged into local waterways that eventually drain into the Yellow Sea via the Yangtze River Delta system. The region's dense river network and proximity to ecologically important coastal wetlands mean that effective treatment is critical to protect downstream aquatic habitats and the marine environment. The plant plays a role in maintaining water quality in the Nantong area, which supports agriculture, fisheries, and urban water supply.

The plant discharges into local rivers that flow through the Yangtze River Delta, ultimately reaching the Yellow Sea. This region features extensive tidal flats and coastal wetlands that support migratory birds and diverse aquatic life. Effective wastewater treatment is essential to prevent nutrient enrichment and protect the ecological health of these downstream environments.
