Overview
Liaoning wastewater treatment plant serves Benxi County in Liaoning Province, China, with a population equivalent of 99,700. The facility operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Benxi County (Benxi Manchu Autonomous County), Liaoning Province, China, along the Jiben Line in Guanyinge Street. It serves a population equivalent of approximately 99,700, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment as a baseline and tertiary treatment for sensitive receiving waters. Typical plants of this scale in Liaoning employ activated sludge processes with nutrient removal to meet Class 1A or 1B standards. The plant discharges treated effluent into local water bodies within the Liao River basin, which ultimately flows into the Bohai Sea. The downstream environment supports diverse aquatic life and is ecologically sensitive due to industrial and agricultural pressures in the region. Proper treatment is critical to protect water quality in the Liao River system and the Bohai Sea coastal zone.
Environmental context
The plant's receiving water body is part of the Liao River basin, which drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Liao River system supports important fisheries and migratory bird habitats. Effluent discharge must comply with strict nutrient limits to prevent eutrophication in the Bohai Sea, which experiences seasonal algal blooms. The region's cold continental climate affects treatment efficiency, particularly biological processes in winter.
Frequently asked questions

The plant serves a population equivalent of approximately 99,700 people.
The treated effluent is discharged into local water bodies within the Liao River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which requires secondary treatment as a minimum and tertiary treatment for sensitive areas.
Plants of this scale in China commonly use activated sludge processes with biological nutrient removal to meet Class 1A or 1B discharge standards, especially when discharging into ecologically sensitive basins like the Liao River.
