Overview
Liaoning wastewater treatment plant serves Fuxin City, Liaoning Province, China, with a population equivalent of 600,000. The facility operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Xiyuan Subdistrict, Xihe District, Fuxin City, Liaoning Province, China. It serves a population of approximately 600,000, classifying it as a large-scale municipal facility within the region. The plant is situated inland, away from coastal areas, and its operations are integral to managing urban wastewater in this industrial and residential area. As a large agglomeration serving over 600,000 people, 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 potential nutrient removal for sensitive water bodies. Facilities of this scale typically employ biological treatment methods such as activated sludge or A2O processes to achieve required effluent quality. The treated effluent is discharged into local waterways within the Xihe River system, which ultimately flows into the Liao River basin. The Liao River is a major watercourse in northeastern China, draining into the Bohai Sea. The plant plays a critical role in protecting downstream aquatic ecosystems and supporting water quality in the region, which faces challenges from industrial and agricultural runoff.
Environmental context
The plant discharges into the Xihe River, a tributary of the Liao River system. The Liao River basin is a vital water resource in Liaoning Province, supporting agriculture, industry, and urban centers. Downstream, the river flows into the Bohai Sea, a semi-enclosed sea with significant ecological importance. The region's watershed faces pressures from industrial pollution and seasonal water scarcity, making effective wastewater treatment essential for maintaining aquatic biodiversity and preventing eutrophication in coastal waters.
Frequently asked questions
The plant is located in Xiyuan Subdistrict, Xihe District, Fuxin City, Liaoning Province, China.
The plant serves approximately 600,000 people, making it a large-scale municipal facility.
The plant discharges into the Xihe River, a tributary of the Liao River, which flows into the Bohai Sea. It helps protect the Liao River basin and downstream coastal waters.
The plant operates under China's GB 18918-2002 standard, which sets discharge limits for municipal wastewater. Large plants like this typically require secondary treatment and may need advanced nutrient removal to protect sensitive water bodies.
For a plant of this scale in China, common treatment processes include activated sludge, A2O (anaerobic-anoxic-oxic), or oxidation ditch systems, often with disinfection and sometimes tertiary filtration to meet strict effluent standards.
