Overview
Jiangsu wastewater treatment plant serves Dongtai City, Jiangsu Province, China, with a population of 10,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Dongtai City, part of Yancheng Prefecture in Jiangsu Province, China. It serves a population of approximately 10,000 people, placing it in the small-to-medium agglomeration category. The plant is situated in the Yangtze River Delta region, a densely populated and economically active area. As a Chinese municipal wastewater facility, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants. For plants serving populations around 10,000, secondary treatment with biological nutrient removal is typically required to meet Class 1-B or Class 1-A standards, depending on the receiving water's sensitivity. The plant's operational details are consistent with national regulations for facilities of this scale. The treated effluent from the plant likely discharges into local waterways that flow into the Yellow Sea via the Sheyang River or other coastal rivers in Jiangsu. The region's flat terrain and extensive canal network mean that treated wastewater can influence downstream water quality in agricultural and estuarine areas. The Yellow Sea coast near Yancheng includes important intertidal wetlands that support migratory birds and aquatic life, making proper treatment essential for ecological protection.
Environmental context
The plant discharges into the local river network that drains into the Yellow Sea via the Sheyang River or adjacent coastal waterways. The downstream environment includes the Yancheng coastal wetlands, which are ecologically sensitive areas supporting diverse bird species and marine life. Proper treatment is critical to prevent nutrient loading and protect the estuarine ecosystem.
