Overview
Liaoning wastewater treatment plant serves Chaoyang, Liaoning, China, with a population of 168,000. It operates under China's national wastewater standards for urban agglomerations.
The Liaoning wastewater treatment plant is located in Xingyuan Subdistrict, Lingyuan City, Chaoyang, Liaoning Province, China. It serves a population of approximately 168,000, classifying it as a medium-to-large urban agglomeration under Chinese wastewater management frameworks. As a plant serving over 100,000 people, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). Regulatory requirements for this scale typically include biological treatment and nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Liao River basin, which flows into the Bohai Sea. The receiving water body supports aquatic ecosystems and is subject to China's water quality standards for surface waters.
Environmental context
The plant's treated effluent enters local streams within the Liao River basin, which flows eastward into the Bohai Sea. This coastal sea is ecologically sensitive, supporting fisheries and migratory bird habitats. The region's semi-arid climate means water resources are limited, making effective wastewater treatment critical for maintaining downstream water quality and ecosystem health.
