Overview
Jiangsu wastewater treatment plant serves Yangzhong City in Jiangsu Province, China, with a population equivalent of 150,000. It operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Sanmao Subdistrict, Yangzhong City, Zhenjiang, Jiangsu Province, China. It serves a population equivalent of 150,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, approximately 50 kilometers from the coast, and discharges into the local river network that ultimately drains into the Yangtze River estuary and the East China Sea. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The plant is expected to meet Class 1A or 1B standards depending on the sensitivity of the receiving water body. The plant likely employs conventional activated sludge or similar biological treatment to comply with national effluent limits. The treated effluent enters the local water system, which flows into the Yangtze River, one of China's most ecologically and economically significant waterways. The Yangtze River supports diverse aquatic life, including endangered species such as the Yangtze finless porpoise, and provides drinking water for millions downstream. Proper treatment at this plant helps protect water quality in the Yangtze estuary and the East China Sea coastal zone.
Environmental context
The plant discharges into the Yangtze River basin, which flows through Jiangsu Province and empties into the East China Sea near Shanghai. The Yangtze estuary is a critical habitat for migratory fish and supports extensive aquaculture. Downstream waters are influenced by tidal flows and industrial activity, making nutrient and pollutant control essential for maintaining ecological balance and protecting coastal fisheries.
Frequently asked questions
The plant is located in Sanmao Subdistrict, Yangzhong City, Zhenjiang, Jiangsu Province, China.
The plant serves a population equivalent of 150,000 people.
The treated effluent is discharged into the local river network, which flows into the Yangtze River and eventually reaches the East China Sea.
The plant must comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for pollutants such as COD, BOD, ammonia, and phosphorus. For a plant of this scale, Class 1A or 1B standards typically apply.
Plants of this size in China commonly use secondary biological treatment processes such as activated sludge, often with nutrient removal (nitrogen and phosphorus) to meet stringent discharge standards.
