Overview
Shanghai wastewater treatment plant serves 51,000 people in Songjiang District, China. It operates under China's national wastewater standards for municipal treatment.
The Shanghai wastewater treatment plant is located in the Songjiang District of Shanghai, China, serving a population of 51,000. The facility is part of the municipal wastewater infrastructure for this rapidly developing region, which combines urban and industrial areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a moderate-scale operation. As a Chinese wastewater treatment facility, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets effluent limits for various pollutants and requires different treatment levels depending on the receiving water body's sensitivity. For a plant serving approximately 51,000 people, secondary treatment with nutrient removal is typical to meet environmental protection goals. The plant discharges treated wastewater into local waterways that eventually drain into the Huangpu River, a major tributary of the Yangtze River. The Yangtze River estuary and East China Sea are the ultimate receiving waters. This watershed supports diverse aquatic life and provides drinking water for millions, making proper treatment essential for ecological and public health.
Environmental context
The plant's treated effluent flows into the Huangpu River, which is a key tributary of the Yangtze River. The Yangtze River estuary and East China Sea are the final receiving waters. This watershed is ecologically sensitive, supporting diverse aquatic species and serving as a critical water source for the Shanghai metropolitan area. Proper nutrient removal is important to prevent eutrophication in downstream waters.
