Overview
The Liaoning wastewater treatment plant serves Beipiao City in Liaoning Province, China, with a population equivalent of 200,000. It operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Beipiao City, Chaoyang, Liaoning Province, China. It serves a population equivalent of 200,000, classifying it as a large agglomeration under Chinese wastewater management frameworks. The plant is situated inland, away from coastal areas, and its operations are integral to the region's water infrastructure. As a large-scale facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Regulatory requirements for this population tier typically involve biological treatment and disinfection. The plant discharges into local water bodies that ultimately drain into the Liao River basin, a major watershed in northeastern China. The Liao River flows into the Bohai Sea, supporting diverse aquatic life and providing water for agriculture and industry. Effective treatment at this plant helps protect downstream ecosystems and water quality.
Environmental context
The plant's treated effluent likely enters the Liao River system, which flows through Liaoning Province and discharges into the Bohai Sea. The Liao River basin supports important fisheries and agricultural irrigation, making nutrient and pollutant control critical. The Bohai Sea is a semi-enclosed water body with limited water exchange, requiring stringent discharge standards to prevent eutrophication and protect marine biodiversity.
Frequently asked questions
The plant is located in Beipiao City, Chaoyang, Liaoning Province, China, along Liang San Road.
The plant serves a population equivalent of 200,000, classifying it as a large-scale municipal facility.
The plant discharges treated effluent into local waterways that are part of the Liao River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's GB 18918-2002 standard, which requires secondary treatment with nutrient removal for large agglomerations to protect sensitive water bodies.
For a plant of this scale, typical treatment includes primary sedimentation, biological treatment (e. g. , activated sludge), and disinfection, often with advanced nutrient removal to meet Class 1A or 1B discharge limits.
