Overview
Liaoning wastewater treatment plant serves Heping District, Shenyang, China, with a population equivalent of 100,000. It operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Heping District, Shenyang, Liaoning Province, China, serving a population equivalent of 100,000. The facility is situated near the Hun River, a tributary of the Liao River system, which ultimately drains into the Bohai Sea. As a plant serving a medium-sized agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. The plant likely employs conventional activated sludge or similar biological treatment processes to meet these standards. The treated effluent is discharged into the Hun River, which flows through Shenyang and joins the Liao River before reaching the Bohai Sea. This water body supports diverse aquatic life and is used for agricultural irrigation downstream. Proper treatment is essential to protect the river's ecological health and the coastal environment of the Bohai Sea.
Environmental context
The plant discharges into the Hun River, a tributary of the Liao River system, which flows into the Bohai Sea. The Liao River basin is an important agricultural and industrial region in northeastern China. The Hun River receives urban runoff and treated wastewater from Shenyang, and its water quality affects downstream ecosystems, including fisheries and wetlands near the Bohai coast. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making effective treatment critical.
