Hebei Wastewater Treatment Plant, Xianghe County, Langfang

The Hebei wastewater treatment plant is located in Xianghe County, Langfang City, Hebei Province, China. It serves a population of approximately 74,000, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. The facility is situated inland, away from coastal areas, and its operations are part of the broader municipal infrastructure for the region. As a plant serving a medium-sized population, it is expected to meet secondary treatment standards under China's national wastewater discharge regulations. These standards align with the country's Water Pollution Prevention and Control Action Plan, which mandates improved treatment levels for urban wastewater. Typical facilities of this scale employ biological treatment methods such as activated sludge. The plant discharges treated effluent into local water bodies within the Hai River basin, which ultimately drains into the Bohai Sea. The receiving waters support agricultural and industrial uses downstream, and the plant plays a key role in protecting water quality in this densely populated region. Proper treatment helps reduce nutrient and pollutant loads, safeguarding both local ecosystems and the marine environment.

The plant is located in the Hai River basin, a major water system in northern China that flows into the Bohai Sea. The downstream environment includes agricultural areas and urban centers that rely on the river for irrigation and industrial water supply. The Bohai Sea is a semi-enclosed marine body that experiences eutrophication pressures from nutrient runoff, making effective wastewater treatment critical for reducing algal blooms and maintaining aquatic biodiversity.
