Overview
Liaoning wastewater treatment plant serves Beizhen City, Liaoning Province, China, with a population of 83,500. The plant operates under China's national wastewater discharge standards.
The Liaoning wastewater treatment plant is located in Beizhen City, Liaoning Province, China, serving a population of approximately 83,500. It is situated in the southern part of the city, near the village of Nanguan, and plays a key role in managing municipal wastewater for this urban area. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This regulation sets limits on biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients to protect receiving water bodies. The treated effluent likely discharges into a local river system that flows into the Bohai Sea via the Liao River basin. The plant's operation helps reduce pollution loads in downstream waters, supporting aquatic life and water quality in the region.
Environmental context
The plant's effluent likely enters a tributary of the Liao River, which flows into the Bohai Sea. The Liao River basin is an important agricultural and industrial region, and the plant helps mitigate nutrient and organic pollution that could otherwise contribute to eutrophication in coastal waters. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it sensitive to pollutant accumulation.
