Overview
Jiangsu wastewater treatment plant serves Haimen District, Nantong, Jiangsu, China. It serves a population of 280,000 and is located within 50 km of the coast, discharging into the Yangtze River estuary.
The Jiangsu wastewater treatment plant is located in Haimen District, Nantong City, Jiangsu Province, China. It serves a population of 280,000 as part of the municipal wastewater infrastructure for this urban area on the northern bank of the Yangtze River. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive coastal zones. The plant's designed capacity is 1.00 (likely 100,000 m³/d or similar unit), indicating a large-scale facility. The plant discharges treated effluent into the Yangtze River, which flows eastward into the East China Sea near Shanghai. The Yangtze estuary is a critical ecological zone supporting diverse aquatic life, including migratory fish species. The plant's proximity to the coast (within 50 km) means its discharge can influence coastal water quality and the health of downstream marine ecosystems.
Environmental context
The plant discharges into the Yangtze River, which flows into the East China Sea. The Yangtze estuary is a major ecological transition zone supporting diverse aquatic life, including important fisheries and migratory species. The plant's coastal proximity means its nutrient and pollutant loads can affect downstream marine habitats and the overall health of the East China Sea.
