Overview
Liaoning wastewater treatment plant serves Shenyang, Liaoning, China, with a population of 112,000. It operates under China's national wastewater standards for urban agglomerations.
The Liaoning wastewater treatment plant is located in the Shenbei New District of Shenyang, the capital of Liaoning Province in northeastern China. It serves a population of approximately 112,000, classifying it as a medium-sized urban agglomeration under Chinese regulatory frameworks. The plant is situated in a rapidly urbanizing area, reflecting the region's industrial and residential growth. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate secondary treatment with nutrient removal for plants serving populations over 100,000. The plant is expected to meet these standards, which align with international best practices for protecting water quality. The facility's design capacity and treatment process details are not publicly available, but its scale suggests a conventional activated sludge system or similar technology. The treated effluent from the plant likely discharges into a local waterway within the Liao River basin, which flows into the Bohai Sea. The Liao River system supports diverse aquatic life and is ecologically significant for the region. The plant's operation helps reduce pollution loads in this watershed, contributing to the health of downstream ecosystems and coastal waters.
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 Liao River watershed supports important fisheries and migratory bird habitats. The Bohai Sea is ecologically sensitive due to its shallow depth and limited water exchange, making it vulnerable to nutrient pollution. The plant's treatment helps mitigate eutrophication risks in this coastal environment.
