Overview
Liaoning wastewater treatment plant serves 340,000 people in Jinzhou District, Dalian, Liaoning Province, China. Located within 50 km of the coast, it discharges treated effluent into the Yellow Sea via local waterways.
The Liaoning wastewater treatment plant is situated in Dagushan Subdistrict, Jinzhou District, Dalian, Liaoning Province, China. It serves a population of approximately 340,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure investment for the region. As a large-scale municipal facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which requires secondary treatment as a minimum, with tertiary treatment often mandated for plants discharging into sensitive water bodies. Given its size and coastal proximity, advanced treatment is likely to protect receiving waters. The plant's effluent ultimately reaches the Yellow Sea through local rivers and drainage networks. The Yellow Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries, migratory bird routes, and diverse marine life. The plant's discharge contributes to the nutrient load in the coastal zone, making effective treatment critical for marine water quality.
Environmental context
The plant discharges into the Yellow Sea via local streams and drainage channels in the Dalian coastal area. The Yellow Sea is a semi-enclosed marginal sea with high ecological sensitivity, supporting important fisheries and serving as a major migratory corridor for shorebirds. Nutrient and pollutant inputs from urban wastewater can impact coastal water quality and marine habitats, necessitating robust treatment standards.
Frequently asked questions
