生物流化床法处理含酚废水的研究

Research on Phenol Wastewater Treatment in Biological Fluidized Bed

含酚废水的存在,对环境造成了愈来愈严重的危害。本文拟通过实际处理试验,进一步探讨含酚废水的生物处理技术及生物流化床法处理含酚废水的有关特性。 1 试验概况试验采用三相生物流化床,装置系统如图1所示。柱体以有机玻璃圆管制成,内径5.5cm,有效高度205cm;载体为粒状活性炭,平均粒径0.49mm,密度1.548g/cm_3,填充量500g。柱体侧面由下而上设六处采样口,以定期进行采样测定。试验废水以工业苯酚添加适量营养成份配制而成。以铬法测COD。

Based on experimental observations and measurements, this paper analyses in detail the coating of the carriers, the relationship between loa-ding and removal efficiency, the response to the shocking of toxious organi-sation phenol and the character of longitudinal distribution in fluidized bed. It proves further the practicableness and advantage of biological flui-dized bed for phenol wastewater treatment.
