Overview
Liaoning wastewater treatment plant serves Xingcheng, Huludao, Liaoning, China, with a population of 130,000. It operates under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in Xingcheng, a county-level city under Huludao, Liaoning Province, China. It serves a population of 130,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline, with tertiary treatment in sensitive watersheds. For plants serving over 100,000 people, advanced treatment is often mandated to protect receiving waters. The plant's treated effluent likely discharges into local rivers that flow into the Bohai Sea, a semi-enclosed sea with significant ecological importance. The region supports fisheries and marine biodiversity, making proper treatment critical for coastal water quality.
Environmental context
The plant is located within 50 km of the coast, and its treated effluent likely drains into rivers flowing into the Bohai Sea. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it sensitive to nutrient pollution from wastewater. Protecting this marine environment requires effective nutrient removal to prevent eutrophication and maintain healthy aquatic ecosystems.
