Overview
Jiangsu wastewater treatment plant serves Hai'an City in Jiangsu Province, China, with a population equivalent of 220,000. The plant has a designed capacity of 1.00 unit and operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Hai'an City, part of Nantong Prefecture in Jiangsu Province, China. Serving a population equivalent of 220,000, the facility is a key component of the region's municipal wastewater infrastructure, handling domestic and industrial flows from the urban area. With a designed capacity of 1.00 unit, the plant is expected to meet secondary treatment standards as mandated by China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations of this scale, Chinese regulations typically require advanced treatment to meet Class 1A or 1B standards, especially in sensitive watersheds. The treated effluent is discharged into local waterways that drain into the Yangtze River Delta region, ultimately reaching the East China Sea. The plant plays a crucial role in protecting the aquatic environment of the densely populated and industrialized Jiangsu province, reducing nutrient and pollutant loads to downstream ecosystems.
Environmental context
The plant discharges into the local river network within the Yangtze River basin, which flows through eastern China and empties into the East China Sea. The downstream environment includes the Yangtze River Delta, a highly productive estuarine ecosystem that supports diverse aquatic life and is an important migratory corridor for fish. Protecting water quality in this region is critical for both ecological health and human uses such as drinking water supply and fisheries.
