Overview
Jiangsu wastewater treatment plant serves Sihong County in Jiangsu, China, with a population equivalent of 150,000. The facility has a designed capacity of 1.00 unit and is located within 50 km of the coast.
The Jiangsu wastewater treatment plant is located in Qingyang Subdistrict, Sihong County, Suqian City, Jiangsu Province, China. It serves a population equivalent of 150,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility serving a significant population, the plant is expected to meet national discharge standards under China's Water Pollution Prevention and Control Law. For large agglomerations, secondary treatment with nutrient removal is typically required, especially in environmentally sensitive areas. The plant's proximity to the coast (within 50 km) suggests that effluent may eventually reach marine waters, necessitating compliance with stringent discharge limits. Given its location in Jiangsu Province, treated wastewater likely drains into the Huai River system or directly into the East China Sea via local waterways. The region supports diverse aquatic ecosystems, including fisheries and migratory bird habitats, making effective wastewater treatment critical for environmental protection.
Environmental context
The plant is situated in Jiangsu Province, within the Huai River basin, which ultimately drains into the East China Sea. The downstream environment includes coastal wetlands and estuaries that support diverse aquatic life, including commercially important fish species. Effective treatment is essential to prevent eutrophication and protect marine biodiversity in the receiving waters.
