Overview
The Jiangsu wastewater treatment plant serves Yizheng City in Jiangsu Province, China, with a designed capacity of 1.00 million cubic meters per day and a population of 45,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Qingshan Town, Yizheng City, within Yangzhou Prefecture, Jiangsu Province, China. The facility serves a population of approximately 45,000 and has a designed capacity of 1.00 million cubic meters per day, indicating it is a medium-scale municipal treatment plant. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The Yangtze River supports diverse aquatic life and provides water for millions of people downstream, making proper treatment essential for protecting water quality and ecosystem health.
Environmental context
The plant's treated effluent flows into tributaries of the Yangtze River, which empties into the East China Sea near Shanghai. The Yangtze basin is a critical freshwater resource supporting agriculture, industry, and biodiversity, including endangered species such as the Chinese sturgeon and finless porpoise. Nutrient loading from wastewater can contribute to eutrophication in downstream lakes and coastal zones, so effective treatment is vital for maintaining ecological balance.
