Overview
Hebei wastewater treatment plant serves 68,000 people in Xiahua Yuan District, Zhangjiakou, Hebei Province, China. The facility operates under national wastewater standards for inland municipal treatment.
The Hebei wastewater treatment plant is located in Xiahua Yuan District, Zhangjiakou City, Hebei Province, China. It serves a population of approximately 68,000 residents, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese municipal plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For agglomerations of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent is discharged into local waterways within the Hai River basin, which ultimately drains into the Bohai Sea. The facility plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Zhangjiakou area.
Environmental context
The plant discharges into the Hai River basin, a major water system in northern China that flows through Hebei Province and Tianjin before reaching the Bohai Sea. The downstream environment supports diverse aquatic life and is used for irrigation, industrial supply, and municipal water. Protecting this watershed from nutrient pollution and pathogens is critical for both ecological health and human use.
