Overview
The Hebei wastewater treatment plant serves Zhangjiakou City in Hebei Province, China, with a population equivalent of 43,300. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in the Wanquan District of Zhangjiakou City, Hebei Province, China. It serves a population equivalent of 43,300, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese municipal plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. Plants of this scale typically employ biological treatment processes such as activated sludge or oxidation ditch to meet Class 1A or 1B standards, depending on the receiving water body's sensitivity. The treated effluent is discharged into local watercourses that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region's semi-arid climate.
Environmental context
The plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird populations. The plant's nutrient removal performance is critical to mitigating eutrophication in downstream waters.
