Liaoning Wastewater Treatment Plant, Ganjingzi District, Dalian | China

The Liaoning wastewater treatment plant is located in Ganjingzi District, Dalian, Liaoning Province, China. It serves a population of 750,000, classifying it as a large agglomeration under Chinese wastewater management frameworks. The plant is situated near the coast of the Yellow Sea, within 50 km of the shoreline. As a major facility serving a large urban population, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating substantial treatment capability. The treated effluent likely discharges into local watercourses that flow into the Yellow Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Yellow Sea supports diverse marine life, including fisheries and migratory bird habitats. Proper treatment is critical to prevent eutrophication and protect coastal water quality in this ecologically sensitive region.

The plant is located in Ganjingzi District, Dalian, on the Liaodong Peninsula, with drainage toward the Yellow Sea. The Yellow Sea is a shallow marginal sea that supports important fisheries and serves as a migratory corridor for birds. Discharges from the plant must comply with China's national standards to prevent nutrient loading and algal blooms in coastal waters. The region's industrial and urban runoff further emphasizes the need for effective wastewater treatment to protect marine ecosystems.
