Overview
Liaoning wastewater treatment plant serves 320,000 people in Huludao, Liaoning, China. It is located within 50 km of the coast, discharging into the Bohai Sea watershed.
The Liaoning wastewater treatment plant is situated in Huludao City, Liaoning Province, China, serving a population of 320,000. The facility is part of the municipal infrastructure for the Longgang District, treating wastewater from the urban area. As a large agglomeration, it plays a key role in protecting local water quality. China's wastewater treatment standards require secondary treatment for urban plants, with stricter nutrient removal in sensitive coastal areas. The plant's designed capacity is 1.00 (likely in 10,000 m³/day), indicating a substantial facility. The plant is expected to meet national discharge standards under the Environmental Protection Law. The treated effluent ultimately reaches the Bohai Sea via local rivers. The Bohai Sea is a semi-enclosed water body with significant ecological and economic importance, supporting fisheries and marine biodiversity. The plant's operation helps reduce nutrient and pollutant loads to this sensitive marine environment.
Environmental context
The plant discharges into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports diverse marine life and is a critical fishing ground. Nutrient pollution from urban runoff and wastewater can cause eutrophication and harmful algal blooms, making advanced treatment important for protecting this ecosystem.
