Overview
Jiangsu wastewater treatment plant serves Sheyang County, Yancheng, Jiangsu, China, with a population of 170,000. It has a designed capacity of 1.00 (units unspecified) and is located inland, over 50 km from the coast.
The Jiangsu wastewater treatment plant is located in Sheyang County, Yancheng City, Jiangsu Province, China. It serves a population of approximately 170,000 people, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a large-scale facility in China, the plant is subject to national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. These regulations require secondary treatment as a minimum, with tertiary treatment often mandated for sensitive water bodies or densely populated areas. Facilities of this scale typically employ biological treatment methods such as activated sludge. The plant discharges treated wastewater into local water bodies that ultimately drain into the Yellow Sea via the Jiangsu coastal river network. The region's watershed supports diverse aquatic life and is important for fisheries and agriculture. Proper treatment is essential to protect downstream ecosystems and maintain water quality for surrounding communities.
Environmental context
The plant's treated effluent flows into the local river system, which drains into the Yellow Sea via the Jiangsu coast. The receiving waters support a mix of freshwater and estuarine habitats, providing critical spawning and nursery grounds for fish and migratory birds. The region's flat terrain and intensive agriculture make nutrient management a key concern to prevent eutrophication in downstream coastal areas.
