Overview
Hebei wastewater treatment plant serves Dongshang Village in Lincheng County, Hebei, China, with a population of 32,800. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Dongshang Village, Lincheng County, Hebei Province, China. It serves a population of approximately 32,800 people, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline for plants of this scale. For sensitive water bodies, tertiary treatment may be mandated. It is expected to meet national effluent standards. The plant discharges treated wastewater into local watercourses that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The Hai River system supports agricultural irrigation and industrial water use in the region, making proper treatment essential for protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant's treated effluent enters local streams within the Hai River basin, a major water system in northern China that flows into the Bohai Sea. The region faces challenges from industrial and agricultural runoff, and the plant's discharge contributes to the overall water quality of the basin. The downstream environment includes estuarine habitats that support diverse aquatic life, including migratory fish species. Effective nutrient removal is critical to prevent eutrophication in the Bohai Sea.
Frequently asked questions
The Hebei wastewater treatment plant is located in Dongshang Village, Lincheng County, Hebei Province, China.
The plant serves approximately 32,800 people, classifying it as a medium-sized municipal wastewater facility.
The plant discharges into local watercourses that are part of the Hai River basin, which ultimately flows into the Bohai Sea. Proper treatment helps protect these water bodies from pollution.
The plant operates under China's national discharge standard GB 18918-2002, which sets limits for pollutants like COD, BOD, and nutrients. For plants of this scale, secondary treatment is typically required.
For medium-sized agglomerations in China, secondary biological treatment (e.g., activated sludge) is standard. In sensitive areas, additional nutrient removal may be mandated to protect receiving waters.
