Overview
Liaoning wastewater treatment plant serves 460,000 people in Hongqibao Village, Anshan, Liaoning, China. It operates under China's national wastewater standards for large agglomerations.
The Liaoning wastewater treatment plant is located in Hongqibao Village, Tiedong District, Anshan City, Liaoning Province, China. Serving a population of 460,000, it is classified as a large agglomeration under Chinese wastewater regulations, which mandate advanced treatment for such scales to protect water resources. As a plant of this size, it is expected to provide at least secondary treatment with nutrient removal, in line with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The facility likely employs biological treatment processes such as activated sludge or A2O to meet effluent standards for COD, BOD, nitrogen, and phosphorus. The plant discharges treated effluent into local waterways that eventually drain into the Liao River basin, a major river system in Northeast China. The Liao River flows into the Bohai Sea, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is critical to prevent eutrophication and protect downstream ecosystems.
Environmental context
The plant's treated effluent enters the Liao River basin, which flows through Liaoning Province and discharges into the Bohai Sea. This coastal sea supports important fisheries and migratory bird habitats. Nutrient loading from wastewater can contribute to algal blooms and hypoxia in the Bohai Sea, making advanced treatment essential for maintaining water quality and ecological balance.
