为探索超声协同电化学氧化的最优试验条件,以实现低耗、高效降解污染物,提出了电化学氧化-超声协同电化学氧化的新型两段式降解工艺,将其应用于甲基橙染料废水的降解.结果表明,经过lh的电化学氧化后,氧化电流效率较低,此时选择超声协同电化学氧化对甲基橙溶液进行矿化.用此两段式工艺降解4h后,甲基橙溶液的TOC去除率达到94.3%,而在相同时间内单独电化学氧化和超声协同电化学氧化TOC去除率分别为76.1%和95.6%.在达到相同TOC去除率的情况下,两段式降解过程的能耗小于超声协同电化学降解的能耗.由此可见,此新型的两段式超声电化学组合降解工艺成功实现了甲基橙溶液的高效、低耗的降解处理.为染料废水的降解提供一种崭新的研究思路.
