Overview
Liaoning wastewater treatment plant serves 160,000 people in Ganjingzi District, Dalian, Liaoning Province, China. The facility discharges treated effluent into the local watershed near Xiajiahezi.
The Liaoning wastewater treatment plant is located in Ganjingzi District, Dalian, Liaoning Province, China, serving a population of 160,000. The facility is situated in the industrial and urban area of Gexhenbao Street, near Xiajiahezi, and operates under China's national wastewater discharge standards. With a designed capacity of 1.00 (units unspecified), the plant is sized to handle the wastewater from a medium-sized agglomeration. China's wastewater treatment regulations require secondary treatment for urban plants, and facilities serving over 100,000 people typically employ biological treatment processes to meet Class 1A or 1B discharge standards. The plant discharges into the local water system, which flows into the Yellow Sea via the Dalian coastal area. The receiving waters support marine biodiversity and are important for local fisheries and aquaculture. Proper treatment is essential to protect coastal water quality and the ecological health of the Bohai Sea region.
Environmental context
The plant's effluent enters the Xiajiahezi stream, which drains into the Yellow Sea near Dalian. This coastal zone supports diverse marine life, including fish and shellfish populations important for local fisheries. The Bohai Sea, a semi-enclosed water body, faces eutrophication risks from nutrient inputs, making effective nutrient removal at treatment plants critical for maintaining water quality and ecosystem health.
