Overview
Liaoning wastewater treatment plant serves Huanren Manchu Autonomous County in Liaoning Province, China, with a population equivalent of 100,000. The facility operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Huanren Manchu Autonomous County, Benxi City, Liaoning Province, China. It serves a population of approximately 100,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant of this scale, it is expected to comply with 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. Typical plants in this region employ activated sludge processes to meet Class 1A or 1B effluent standards. The plant discharges into local watercourses that ultimately drain into the Yalu River system, which flows into the Yellow Sea. This watershed supports diverse aquatic life and is an important ecological corridor in northeastern China. The plant's operation is critical for protecting downstream water quality and maintaining the ecological health of the region's rivers and coastal waters.
Environmental context
The plant's treated effluent enters local streams that feed into the Hun River, a tributary of the Yalu River, which forms the border between China and North Korea before emptying into the Yellow Sea. This watershed supports diverse aquatic species and provides water for agriculture and communities downstream. The plant's discharge must meet stringent standards to protect the ecological integrity of this transboundary river system and the marine environment of the Yellow Sea.
