Overview
The Hebei wastewater treatment plant serves Zhangjiakou City, Hebei Province, China, with a population of 39,700. It operates under China's national wastewater standards.
The Hebei wastewater treatment plant is located in Chicheng County, Zhangjiakou City, Hebei Province, China. It serves a population of approximately 39,700, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations require secondary treatment for urban plants of this scale, with effluent standards set by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Typical plants serving this population size employ biological treatment methods such as activated sludge or sequencing batch reactors. The plant discharges treated wastewater into local water bodies within the Hai River basin, which ultimately drains into the Bohai Sea. Proper treatment is essential to protect downstream aquatic ecosystems and support water quality in this region, which faces challenges from industrial and agricultural runoff.
Environmental context
The plant is located in the Hai River basin, which drains into the Bohai Sea. The receiving water body is likely a tributary of the Yongding River or a local stream. The downstream environment supports diverse aquatic life and is important for regional water supply and irrigation. Effective treatment helps mitigate nutrient loading and pollution in this ecologically sensitive watershed.
