Overview
The Hebei wastewater treatment plant serves 160,000 people in Bazhou, Langfang, Hebei, China. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Bazhou, a county-level city under Langfang prefecture in Hebei Province, China. The facility serves a population of approximately 160,000, placing it in the medium-to-large 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), set effluent limits based on receiving water sensitivity. The population served suggests a capacity in the range of 40,000 to 60,000 cubic meters per day. The plant discharges treated effluent into local waterways that ultimately drain into the Bohai Sea via the Hai River system. The Hai River basin is a major water system in northern China, supporting agriculture, industry, and urban water supply. The plant's operation is critical for protecting downstream water quality and the ecological health of the Bohai Sea coastal zone.
Environmental context
The Hebei plant's treated effluent flows into the Hai River basin, which drains into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea is ecologically sensitive, supporting diverse marine life including fisheries and migratory bird habitats. The Hai River system receives urban and industrial discharges from multiple cities, making nutrient and pollutant management crucial to prevent eutrophication and hypoxia in the coastal zone.
