Overview
The Hebei wastewater treatment plant serves Wen'an County in Langfang City, Hebei Province, China, with a population equivalent of 60,000. It 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 approximately 60,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For facilities serving around 60,000 people, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into local waterways that ultimately drain into the Bohai Sea via the Hai River system. The downstream environment supports diverse aquatic life and is an important ecological corridor in the North China Plain, requiring careful management of nutrient and pollutant loads.
Environmental context
The plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird habitats. Nutrient loading from upstream sources can contribute to eutrophication in coastal waters, making effective treatment critical for downstream water quality.
