Overview
Hebei wastewater treatment plant serves Zhangjiakou, Hebei, China, with a population of 75,000. It operates under China's national wastewater standards for inland facilities.
The Hebei wastewater treatment plant is located in Zhangbei County, Zhangjiakou City, Hebei Province, China. It serves a population of approximately 75,000 people, placing it in the medium-agglomeration category under Chinese wastewater management frameworks. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For inland plants like this, secondary treatment with nutrient removal is typically required to protect local water bodies. The plant discharges into the local watershed, which ultimately drains into the Hai River system and then into the Bohai Sea. The region's semi-arid climate and agricultural land use make proper treatment essential for downstream water quality and ecosystem health.
Environmental context
The plant's treated effluent flows into the Hai River basin, a major water system in northern China that discharges into the Bohai Sea. This watershed supports diverse aquatic life and is used for irrigation, making nutrient and pollutant control critical. The Bohai Sea is a semi-enclosed marine environment sensitive to eutrophication from upstream discharges.
