Overview
The Hebei wastewater treatment plant serves Ningjin County in Hebei Province, China, with a population of 189,000. It operates under China's national wastewater regulations.
The Hebei wastewater treatment plant is located in the Dongcheng Industrial Park Community of Ningjin County, Hebei Province, China. It serves a population of approximately 189,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The population served indicates significant infrastructure. The treated effluent is likely discharged into a local waterway within the Hai River basin, which flows into the Bohai Sea. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal environment.
Environmental context
The plant discharges into a tributary of the Hai River system, which ultimately flows into the Bohai Sea. The Hai River basin is a densely populated and industrialized region, making wastewater treatment critical for controlling nutrient and pollutant loads. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it sensitive to eutrophication and algal blooms from upstream discharges.
