Overview
Liaoning wastewater treatment plant serves Xinglongtai District, Panjin, Liaoning, China, with a population equivalent of 350,000. The facility has a designed capacity of 1.00 unit and operates under China's national wastewater discharge standards.
Liaoning wastewater treatment plant is located in Xinglongtai District, Panjin City, Liaoning Province, China. It serves a population equivalent of 350,000, classifying it as a large agglomeration under Chinese wastewater management guidelines. The facility is situated in the urban area of Panjin, a city known for its petrochemical industry and proximity to the Liaohe River basin. As a large-scale plant, Liaoning is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The plant's designed capacity is 1. Chinese regulations require such facilities to achieve effluent quality suitable for discharge into surface waters or for reuse, with stringent limits on pollutants like COD, BOD, and ammonia nitrogen. The plant's treated effluent likely discharges into the Liaohe River system, which flows into the Bohai Sea. The Liaohe basin supports diverse aquatic life and is an important water resource for agriculture and industry in Liaoning Province. Downstream, the Bohai Sea is a semi-enclosed marginal sea with significant ecological and economic importance, hosting fisheries and shipping routes. Proper treatment at this plant helps protect both the riverine ecosystem and coastal waters from nutrient pollution and industrial contaminants.
Environmental context
The plant's treated effluent likely enters the Liaohe River, which flows southeast into the Bohai Sea. The Liaohe basin is a major agricultural and industrial region in northeastern China, and its waters support diverse fish species and migratory birds. Downstream, the Bohai Sea is a critical marine ecosystem facing eutrophication pressures from nutrient loads; effective wastewater treatment at this plant helps reduce nitrogen and phosphorus inputs, protecting coastal water quality and marine biodiversity.
