摘要
为了提高液相放电等离子体技术产生的活性自由基浓度,提出液相放电等离子体与臭氧联用技术处理KN-B染料废水。该联用技术相对于单一技术在处理KN-B染料废水90 min后脱色率提高26.4%,COD去除率提高22.4%。液相放电等离子体技术单独使用以及与臭氧联用处理KN-B染料废水的降解反应均符合一级动力学特征。通过测定联用方法与单一方法产生.OH相对浓度,表明联用方法提高了.OH的浓度,具有很好的协同性。
In order to increase the production of hydroxyl radical （· OH） concentration by hquid-phase discharge plasma, the method of coupling liquid-phase discharge plasma and ozone is proposed. The dyeing wastewater of KN-B is degraded by the coupling method and the single method. Compared with the single method, the coupling method has a high decoloration rate and the COD removal rate. After 90 min, the decoloration rate and the COD removal rate increase respectively by 26.4% ,22.4%. The KN-B degradation by the coupling method and the single method accords with the first-order kinetics. The · OH concentration is increased by the coupling method. The cooperative analysis of the coupling technique is proved by measuring the relative · OH concentration with the different methods.
