摘要
在静态和动态的条件下采用填充床电极反应器(PBER)对核糖核酸(RNA)生产废水进行了详细研究。静态处理结果证明床层中充填的活性炭具有拓展阳极的能力,能够实现运行进程中的原位再生。以IrO2/Ta2O5/Ti为阳极、10 mm的球状活性炭(GAC)为填料,极板间距为50 mm,在0.5 L/h、0.80 A和1.30 A的条件下进行的动态试验。结果表明,COD的变化均遵循零级反应模式,尤其是当引入"填料电流利用系数"参数后,根据Faraday定律所得的新公式能够较为精确的描述有机物氧化过程中电流效率和电耗的变化趋势。
Ribonucleic acid（RNA） manufacturing wastewater treatment was conducted in detail by a packed-bed electrode reactor（PBER） under static and dynamic conditions for dealing with high salinity organic wastewater.Experimental results at static state revealed that the activated carbon packed between electrodes could effectively expand the anodic area and be in situ regenerated in electric field.At the same time,the dynamic experiments with IrO2/Ta2O5/Ti anodes,10 mm size granular activated carbon（GAC） and inter-electrode gap of 50 mm under operation conditions of 0.5 L/h flow rate and 0.80 A or 1.30 A current illustrated the variation of COD followed zero order kinetics.Further,series of new equation for accurate estimation of average current efficiency and energy consumption were obtained when a new parameter ＂current utilization coefficient on filling＂was introduced into Faraday＇s law.
