Overview
Jiangsu wastewater treatment plant serves 190,000 people in Dongtai, Yancheng, Jiangsu Province, China. It operates under China's national wastewater discharge standards for municipal facilities.
The Jiangsu wastewater treatment plant is located in Dongtai, a city under the administration of Yancheng in Jiangsu Province, China. Serving a population of 190,000, this facility is a key component of the region's municipal wastewater infrastructure, handling domestic sewage from a medium-sized urban agglomeration. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent quality requirements based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically expected, especially when discharging into sensitive water bodies. It likely meets the national standards for its category. The plant discharges into local waterways that ultimately drain into the Yellow Sea via the coastal river network of Jiangsu. The region's flat terrain and dense water system make proper treatment critical to prevent eutrophication in downstream estuaries and coastal zones. The facility plays a vital role in protecting both local freshwater resources and the marine environment of the East China Sea.
Environmental context
The plant's treated effluent enters the river network of the Jiangsu coastal plain, which flows into the Yellow Sea via the Sheyang River or similar watercourses. This region supports important fisheries and migratory bird habitats along the East China Sea coast. Nutrient loading from untreated or inadequately treated wastewater could contribute to algal blooms and hypoxia in the nearshore marine environment, making effective treatment essential for ecological health.
Frequently asked questions
The plant is located in Dongtai, a city under Yancheng prefecture in Jiangsu Province, China. Its coordinates are approximately 32.866 N, 120.291 E.
The plant serves a population of 190,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management categories.
The plant discharges treated effluent into the local river network of the Jiangsu coastal plain, which eventually drains into the Yellow Sea. The region's waterways flow eastward to the coast.
The plant operates under China's national wastewater discharge standards, primarily GB 18918-2002, which sets limits for pollutants like COD, BOD, ammonia, and phosphorus. Local environmental protection bureaus enforce these standards.
For a plant of this scale in China, secondary biological treatment with nutrient removal is standard. This typically includes activated sludge processes and may incorporate advanced treatment if discharging into sensitive water bodies.
