Abstract:为提高臭氧降解和脱色染料废水的效果,通过沿面放电臭氧生成一废水处理一体化反应器降解偶氮染料废水研究了供电电源类型、放电电压、放电反应器内注入的气体组分及流量、废水电导率、催化剂等因素对染料降解的影响。研究结果表明:同50Hz工频电源相比,在相同的输入功率下,高频电源降解偶氮染料效果更快;沿面放电反应器内注入的气体成分影响染料降解率,注入氧气时,甲基红降解率最高,注入氮气时,甲基红几乎没有降解;注入气体流量影响气相和液相臭氧浓度及染料废水的湍流度,进而影响甲基红的降解率;废水电导率对甲基红降解影响不大;二氧化钛添加量影响甲基红的降解,染料降解初期,适量的二氧化钛有利于甲基红的降解。
