Overview
The Hebei wastewater treatment plant serves Zhangjiakou City, Hebei Province, China, with a population of 71,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Huai'an County, Zhangjiakou City, Hebei Province, China. It serves a population of approximately 71,000 people, classifying it as a medium-sized municipal facility in the region. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for various pollutants. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent likely discharges into a local river within the Hai River basin, which flows into the Bohai Sea. This coastal discharge area is ecologically important, supporting fisheries and marine biodiversity, making proper treatment essential to prevent eutrophication and protect downstream aquatic life.
Environmental context
The plant is located inland in Hebei Province, within the Hai River basin. The Hai River system drains into the Bohai Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The downstream environment supports diverse aquatic life and important coastal fisheries, requiring effective wastewater treatment to maintain water quality.
