Overview
The Hebei wastewater treatment plant serves Xuanhua District, Zhangjiakou, Hebei Province, China, with a population equivalent of 250,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Xuanhua District, Zhangjiakou City, Hebei Province, China. It serves a population of approximately 250,000, classifying it as a large-scale municipal facility within the region's wastewater infrastructure. As a plant serving over 150,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Facilities of this scale typically employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent 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, and its ecological health is critical for the region's water security and the marine environment of the Bohai Sea.
Environmental context
The plant's treated effluent enters the local drainage network within the Hai River basin, which flows eastward into the Bohai Sea. The Hai River system is heavily regulated due to industrial and agricultural pressures, and the Bohai Sea receives significant nutrient loads from multiple rivers, contributing to eutrophication and algal blooms. The plant's discharge must comply with stringent nutrient limits to protect downstream water quality and marine ecosystems.
