Overview
Hebei wastewater treatment plant serves Guan County in Shandong, China, with a population of 44,300. The plant discharges into local waterways under China's national wastewater standards.
The Hebei wastewater treatment plant is located in Guan County, Liaocheng, Shandong Province, China. It serves a population of approximately 44,300, classifying it as a medium-sized municipal facility under China's urban wastewater treatment framework. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge or similar biological processes to meet Class 1A or 1B effluent standards. The plant's treated effluent is discharged into local rivers that ultimately flow into the Bohai Sea via the Hai River system. This watershed supports agricultural irrigation and industrial water use, making effective treatment critical for protecting downstream water quality and aquatic ecosystems in the Bohai Sea basin.
Environmental context
The plant discharges into the Hai River basin, which drains into the Bohai Sea, a semi-enclosed marginal sea with limited water exchange. The region faces challenges from industrial and agricultural runoff, and the plant's nutrient removal helps mitigate eutrophication risks in coastal waters. The Bohai Sea supports fisheries and migratory bird habitats, emphasizing the importance of consistent treatment performance.
