研究了过滤管式Ti/RuO_(2)-IrO_(2)(钌铱)电极对丙烯腈工业废水的电化学降解性能,探究了进水流量、电流密度和氯化钠浓度等对电化学降解效果的影响。降解过程遵循拟一级动力学,最佳的降解动力学常数和能耗分别为0.0529 min^(-1)和1.33 Wh/L。降解90 min后水中氨氮和COD分别去除了77.7%和89.4%。结果表明,过滤管式钌铱电极对丙烯腈工业废水的处理具有可行性和高效性。

This study investigated the electrochemical degradation performance of a tubular filter-type Ti/RuO_(2)-IrO_(2)electrode for treating acrylonitrile industrial wastewater.We examined the influence of factors such as influent flow rate,current density,and sodium chloride concentration on the effectiveness of electrochemical degradation.The degradation process followed pseudo-first-order kinetics,with the optimal degradation rate constant and energy consumption being 0.0529 min-1 and 1.33 Wh/L,respectively.After 90 minutes of degradation,77.7%of ammonia nitrogen and 89.4%of COD were removed from the water.These results demonstrate the feasibility and high efficiency of using the tubular filter-type Ti/RuO_(2)-IrO_(2)electrode for the treatment of acrylonitrile industrial wastewater.
