Overview
Liaoning wastewater treatment plant serves Shenyang, Liaoning, China, with a population of 1,700,000. It operates under China's national wastewater standards.
The Liaoning wastewater treatment plant is located in Shenyang, the capital of Liaoning province in northeastern China. It serves a large urban population of 1,700,000, making it a major facility in the region's wastewater infrastructure. The plant is situated in the Yuhong district, near the Hun River, which flows through the city. As a large-scale municipal plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving over 1 million people, advanced treatment is typically required to meet Class 1A standards, especially if discharging into sensitive water bodies. Its scale implies a multi-stage system including biological treatment and disinfection. The treated effluent likely discharges into the Hun River, a tributary of the Liao River, which flows into the Bohai Sea. The Liao River basin is ecologically important, supporting diverse aquatic life and providing water for agriculture and industry. The plant plays a critical role in protecting water quality in this densely populated and industrialized region.
Environmental context
The plant discharges into the Hun River, which joins the Liao River before reaching the Bohai Sea. The Liao River basin is a major water system in northeastern China, supporting agriculture, industry, and urban water supplies. Downstream ecosystems include wetlands and estuaries that provide habitat for migratory birds and fish. The Bohai Sea is a semi-enclosed sea with significant ecological and economic importance, and nutrient pollution from upstream sources can contribute to eutrophication and algal blooms.
