Overview
Jiangsu wastewater treatment plant serves Tianning District, Changzhou, China, with a designed capacity of 1.00 and a population served of 150,000. It operates under China's national wastewater standards.
The Jiangsu wastewater treatment plant is located in Tianning District, Changzhou, Jiangsu Province, China. It serves a population of 150,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant's designed capacity is 1.00, indicating its scale in treating urban wastewater from the surrounding community. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (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 to protect receiving waters. Regulatory compliance is expected. The treated effluent is discharged into local waterways that eventually drain into the Yangtze River Delta region, a densely populated and economically vital area. The downstream environment includes the Yangtze River and its estuary, which supports diverse aquatic life and is critical for water supply and fisheries. Proper treatment helps mitigate eutrophication risks in this sensitive watershed.
Environmental context
The plant's discharge enters the local river network within the Yangtze River basin, ultimately flowing into the East China Sea. The Yangtze River Delta is a highly urbanized and industrialized region, where nutrient pollution from wastewater can contribute to algal blooms and hypoxia in coastal waters. The plant's treatment performance is important for protecting downstream aquatic ecosystems and maintaining water quality for human use.
