Overview
Hebei wastewater treatment plant serves Dacheng County in Langfang, Hebei, China, with a population of 32,500. The plant operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Dacheng County, Langfang City, Hebei Province, China. It serves a population of approximately 32,500, placing it in the small-to-medium agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), plants of this scale are typically required to meet Class 1-A or 1-B standards, which mandate biological treatment with nutrient removal. Standard practice for similar facilities in Hebei includes activated sludge processes with secondary treatment. The plant discharges into local waterways that ultimately drain into the Hai River system, which flows into the Bohai Sea. The Hai River basin is a major water resource for northern China and supports agricultural, industrial, and urban uses. The plant plays a role in protecting downstream water quality in this densely populated region.
Environmental context
The plant's treated effluent enters the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Hai River system is heavily regulated due to industrial and agricultural runoff, and the plant helps reduce nutrient and pollutant loads. The Bohai Sea is a semi-enclosed water body with significant ecological importance, supporting fisheries and marine biodiversity.
