Overview
The Hebei wastewater treatment plant serves 140,000 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, Hebei Province, China. It serves a population of approximately 140,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes with biological nutrient removal to meet Class 1A or 1B standards. The plant discharges treated effluent into local waterways that ultimately drain into the Bohai Sea via the Hai River system. The receiving water bodies support agricultural irrigation and industrial use, and the plant plays a key role in protecting downstream water quality in the densely populated North China Plain.
Environmental context
The plant is located in the Hai River basin, which drains into the Bohai Sea. The region faces challenges from industrial and agricultural runoff, and the plant's treated effluent helps reduce nutrient loading in downstream rivers and coastal waters. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it sensitive to eutrophication from upstream pollution.
