Overview
Jiangsu wastewater treatment plant serves Suining County, Xuzhou, Jiangsu, 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 Suining County, Xuzhou City, 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 its treated effluent likely discharges into local rivers that flow toward the Yellow Sea. As a facility serving 150,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This national standard sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus, with stricter requirements for plants discharging into sensitive water bodies. Facilities of this scale typically employ secondary biological treatment (e. g. , activated sludge) with potential nutrient removal. The plant's receiving water body is not explicitly named, but given its location in the Huai River basin, treated wastewater likely flows into tributaries of the Huai River or directly into the Hongze Lake system before reaching the Yellow Sea. This region supports intensive agriculture and is ecologically sensitive to nutrient pollution, making effective treatment critical for downstream water quality and aquatic ecosystem health.
Environmental context
The plant is located in the Huai River basin, one of China's major river systems that drains into the Yellow Sea. The Huai River and its tributaries, such as the Si River, provide water for irrigation and domestic use in Jiangsu and Anhui provinces. Downstream, the river flows through Hongze Lake, a large freshwater lake that supports fisheries and biodiversity. Nutrient loading from wastewater discharges can contribute to eutrophication in the lake and coastal waters, affecting aquatic life and water quality. The region's flat terrain and dense population amplify the importance of effective wastewater treatment to protect these water bodies.
Frequently asked questions
The plant is located in Suining County, Xuzhou City, Jiangsu Province, China, approximately 50 kilometers inland from the coast.
The plant serves a population equivalent of 150,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management.
The treated effluent likely discharges into local rivers within the Huai River basin, eventually reaching the Yellow Sea via Hongze Lake.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets limits on pollutants like COD, BOD, and nutrients.
Facilities of this scale typically employ secondary biological treatment (e. g. , activated sludge) with potential nutrient removal to meet GB 18918-2002 standards, especially if discharging into sensitive water bodies.
