Overview
Liaoning wastewater treatment plant serves 220,000 people in Shahekou District, Dalian, Liaoning Province, China. Located within 50 km of the coast, it discharges into the Yellow Sea via local waterways.
The Liaoning wastewater treatment plant is located in Shahekou District, Dalian, Liaoning Province, China, serving a population of 220,000. The facility is situated near the Malan River fitness trail in the Xinghai Bay area, a coastal urban zone. As a medium-to-large agglomeration, it plays a key role in managing municipal wastewater for this part of Dalian. Chinese wastewater treatment plants of this scale typically employ secondary or advanced treatment processes to meet national discharge standards. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a significant infrastructure investment. China's national wastewater regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set strict limits on effluent quality. The plant's treated effluent ultimately reaches the Yellow Sea via the Malan River and Dalian Bay. The Yellow Sea is a semi-enclosed marginal sea with important fisheries and marine biodiversity. The plant's proximity to the coast (within 50 km) means its discharge can influence coastal water quality, making effective treatment critical for protecting marine ecosystems and recreational waters.
Environmental context
The plant discharges into the Malan River, which flows through Dalian into Dalian Bay and then the Yellow Sea. The Yellow Sea supports diverse marine life, including fisheries and migratory species. Coastal waters near Dalian are used for aquaculture and recreation, so nutrient and pollutant control from wastewater is essential to prevent eutrophication and maintain water quality.
