Overview
Liaoning wastewater treatment plant serves 51,000 people in Zhongshan District, Dalian, Liaoning Province, China. The facility discharges treated effluent into the Yellow Sea via local waterways.
The Liaoning wastewater treatment plant is located in Taoyuan Subdistrict, Zhongshan District, Dalian, Liaoning Province, China. It serves a population of approximately 51,000, classifying it as a medium-sized municipal facility under Chinese wastewater regulations. China's wastewater treatment standards, governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline for urban plants. Facilities serving populations above 50,000 typically operate under Class I-A or I-B discharge limits, depending on the receiving water's sensitivity. The plant's designed capacity is 1.00 (likely in 10,000 m³/d), indicating a moderate scale. The plant's treated effluent ultimately reaches the Yellow Sea, a semi-enclosed marginal sea of the Pacific Ocean. The coastal discharge zone supports diverse marine life, including fisheries and migratory species. Proper nutrient removal is critical to prevent eutrophication in the coastal waters of the Liaodong Peninsula.
Environmental context
The plant discharges into the Yellow Sea via local drainage networks in the Dalian area. The Yellow Sea is a productive marine ecosystem supporting commercial fisheries and serving as a migratory corridor for birds and marine species. Coastal waters near Dalian face pressures from urban runoff and industrial activities, making effective wastewater treatment essential for maintaining water quality and protecting aquatic habitats.
