Overview
Liaoning wastewater treatment plant serves Lushunkou District, Liaoning, China, with a designed capacity of 1.00 and a population equivalent of 130,000. The plant discharges treated effluent into local water bodies within 50 km of the coast.
The Liaoning wastewater treatment plant is located in Lushunkou District, Liaoning Province, China, serving a population equivalent of 130,000. The facility is situated in the coastal region of the Liaodong Peninsula, within 50 km of the Bohai Sea. As a medium-to-large agglomeration, the plant plays a key role in managing municipal wastewater for the district. Under China's national wastewater regulations, plants serving over 100,000 people are typically required to meet advanced treatment standards, especially in environmentally sensitive coastal areas. The plant's designed capacity is 1.00 (likely in 10,000 m³/day), indicating a facility sized for the served population. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The treated effluent from the plant ultimately discharges into the Bohai Sea, a semi-enclosed marginal sea that supports diverse marine life and is ecologically sensitive due to limited water exchange. The plant's proximity to the coast underscores the importance of effective nutrient removal to prevent eutrophication and protect coastal ecosystems.
Environmental context
The plant discharges into the Bohai Sea via local rivers and drainage channels. The Bohai Sea is a semi-enclosed water body with limited tidal exchange, making it vulnerable to nutrient pollution and algal blooms. The surrounding watershed includes agricultural and urban areas, contributing to runoff that the plant helps mitigate. Protecting this marine environment requires advanced treatment to reduce nitrogen and phosphorus loads.
Frequently asked questions
The plant is located in Lushunkou District, Liaoning Province, China, near the coast of the Bohai Sea.
The plant serves a population equivalent of 130,000 people in Lushunkou District.
Treated effluent is discharged into local water bodies that flow into the Bohai Sea, a semi-enclosed coastal sea.
The plant must comply with China's GB 18918-2002 discharge standard, which sets limits for pollutants like COD, BOD, nitrogen, and phosphorus. Plants serving over 100,000 people often require advanced treatment.
For agglomerations of this size, Chinese regulations typically mandate secondary treatment with nutrient removal, and often tertiary treatment to meet stricter standards in sensitive coastal areas.
