Overview
Jiangsu wastewater treatment plant serves Qixia District, Nanjing, China, with a population equivalent of 45,000. The facility operates under China's national wastewater discharge standards.
The Jiangsu wastewater treatment plant is located in Qixia District, Nanjing, Jiangsu Province, China. It serves a population equivalent of 45,000, classifying it as a medium-sized municipal facility within the rapidly urbanizing Yangtze River Delta region. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to meet Class 1-A or 1-B effluent limits, which include biological treatment and nutrient removal. Regulatory compliance is enforced by local environmental protection bureaus. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River, one of China's most ecologically and economically significant rivers. The Yangtze supports diverse aquatic life and provides drinking water for millions, making effective wastewater treatment critical for downstream water quality and ecosystem health.
Environmental context
The plant's treated effluent flows into the Yangtze River basin, which empties into the East China Sea near Shanghai. The Yangtze is a major migratory corridor for fish species such as the Chinese sturgeon and supports extensive wetlands that provide flood control and water purification. Protecting this watershed is essential for maintaining biodiversity and water quality for downstream communities.
