Overview
Jiangsu wastewater treatment plant serves Qidong City in Jiangsu Province, China, with a designed capacity of 1.00 million cubic meters per day and a population served of 380,000.
The Jiangsu wastewater treatment plant is located in Qidong City, Jiangsu Province, China, within the Yangtze River Delta region. It serves a population of 380,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1.00 million cubic meters per day, indicating significant infrastructure to handle municipal wastewater from the urban area. As a large-scale facility in China, the plant is expected to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Action Plan. These regulations require advanced treatment for plants serving over 100,000 people, typically including biological nutrient removal to protect sensitive water bodies. Its scale suggests compliance with tertiary treatment requirements. The plant discharges into the local watershed, which ultimately drains into the East China Sea via the Yangtze River estuary. The receiving water body supports diverse aquatic life and is an important migratory corridor for fish species. The plant's location within 50 km of the coast means its effluent can influence coastal water quality, necessitating stringent nutrient control to prevent eutrophication in the marine environment.
Environmental context
The plant's treated effluent flows into the Yangtze River Delta watershed, which discharges into the East China Sea. This coastal region supports ecologically sensitive habitats, including tidal flats and wetlands that provide nursery grounds for fish and shellfish. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the estuary, making advanced treatment critical for maintaining water quality and biodiversity.
