Overview
Hebei wastewater treatment plant serves 85,000 people in Zhangjiakou, Hebei, China. It is an inland facility operating under China's national wastewater standards.
The Hebei wastewater treatment plant is located in the Dongxingyuan area of Yu County, within Zhangjiakou City, Hebei Province, China. The facility serves a population of approximately 85,000, placing it in the medium-scale category for Chinese municipal wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water's sensitivity. For plants serving populations of this size, secondary biological treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially if discharging into sensitive water bodies. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into a local river or stream within the Hai River basin. This basin ultimately drains into the Bohai Sea, supporting agricultural and urban water uses along its course. The facility plays a key role in protecting local water quality and downstream ecosystems.
Environmental context
The plant's treated effluent likely enters a tributary of the Yongding River, part of the larger Hai River system that flows into the Bohai Sea near Tianjin. The Hai River basin is heavily utilized for agriculture and industry, making nutrient and pollutant control critical to prevent eutrophication in the Bohai Sea. The plant's inland location reduces direct marine impact, but its discharge affects freshwater habitats and downstream coastal zones.
