Overview
Liaoning wastewater treatment plant serves Shenyang, Liaoning, China, with a population of 180,000. It operates under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in the Hunnan District of Shenyang, the capital of Liaoning Province in northeastern China. It serves an estimated population of 180,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants serving this population tier are typically required to achieve at least secondary treatment, with more stringent Class 1A or 1B standards in environmentally sensitive areas. The regulatory framework ensures a baseline level of pollutant removal. The treated effluent is discharged into the local water system within the Liao River basin, which ultimately flows into the Bohai Sea. The plant plays a key role in protecting downstream water quality in a region characterized by heavy industrial activity and urban development.
Environmental context
The plant discharges into the Liao River basin, which drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The downstream environment supports diverse aquatic life and is an important fishing ground. The region faces challenges from industrial pollution and urban runoff, making effective wastewater treatment critical for maintaining ecological balance and protecting coastal water quality.
