Overview
Jiangsu wastewater treatment plant serves 80,000 people in Jiangbei New District, Nanjing, Jiangsu Province, China. The facility operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Changlu Subdistrict, Jiangbei New District, within the Liuhe District of Nanjing, Jiangsu Province, China. It serves a population of approximately 80,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving this population scale, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for chemical oxygen demand, biochemical oxygen demand, suspended solids, ammonia nitrogen, and total phosphorus. The standard requires secondary biological treatment as a baseline, with more stringent requirements for plants discharging into sensitive water bodies. The plant's treated effluent likely discharges into local waterways that drain into the Yangtze River basin, given Nanjing's location along the lower Yangtze. The Yangtze River is ecologically significant, supporting diverse aquatic life including the critically endangered Yangtze finless porpoise and serving as a vital water resource for millions of people downstream.
Environmental context
The plant is located in the Yangtze River Delta region, with its treated effluent ultimately draining into the Yangtze River, which flows into the East China Sea. The Yangtze River basin supports a rich ecosystem including migratory fish species and provides drinking water for major cities. The plant's discharge contributes to the nutrient load in the river, making effective treatment critical for downstream water quality and aquatic habitat preservation.
Frequently asked questions
The plant is located in Changlu Subdistrict, Jiangbei New District, Liuhe District, Nanjing, Jiangsu Province, China.
The plant serves approximately 80,000 people in the Jiangbei New District area of Nanjing.
The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River basin, which flows into the East China Sea.
The plant operates under China's national standard GB 18918-2002, which sets discharge limits for pollutants. Plants serving populations over 50,000 typically require secondary treatment with nutrient removal.
For a medium-sized agglomeration of 80,000 people, Chinese regulations typically mandate secondary biological treatment, often with additional nutrient removal to meet Class 1A or 1B discharge standards, especially when discharging into sensitive water bodies like the Yangtze River.
