Overview
Hebei wastewater treatment plant serves Langfang City, Hebei Province, China, with a population equivalent of 160,000. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Wen'an County, Langfang City, Hebei Province, China. It serves a population equivalent of 160,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant serving over 100,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which typically requires secondary treatment with nutrient removal for facilities of this scale. Regulatory compliance ensures adequate treatment before discharge. The treated effluent likely discharges into local water bodies within the Hai River basin, which ultimately flows into the Bohai Sea. The plant plays a critical role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated North China Plain.
Environmental context
The plant is situated in the Hai River basin, a major water system in northern China that drains into the Bohai Sea. The downstream environment includes agricultural and urban areas, where treated wastewater helps maintain river flow and supports irrigation. The Bohai Sea is a semi-enclosed water body sensitive to nutrient pollution, making effective treatment essential for preventing eutrophication and protecting marine biodiversity.
