摘　　要：流光放电技术是一种新的高级氧化处理技术,能够利用放电产生的高能粒子高效降解污染物。针对印染废水处理,实验建立了一套流光放电水处理系统,利用阵列针-板结构进行流光放电,考察输入电压和反应器功率的关系,分析pH、电压峰值和放电间距等因素对罗丹明B模拟印染废水处理效果的影响。结果表明,酸性条件有利于罗丹明B的降解,电压峰值高、放电间距小,处理效果好。在pH约为1、放电间距为12 mm、电压峰值为13.8 kV时,经过60 min处理,罗丹明B去除率达到90.8%。Streamer discharge is a novel advanced oxidation technology for waste water treatment, and pollutant can be degraded efficiently by the high-energy particle produced in the discharge process. For dyeing wastewater treatment, a streamer discharge waste water treatment system was built, and the streamer was generated by the pin-plate array discharge configuration. The relationship between input voltage and reactor power was investigated, as well as the influences of pH value, peak voltage and distance of pin-plate electrode was discussed, so that the removal efficiency of dyeing wastewater simulated by rhodamine B solution was evaluated. The experimental results showed that, acidity is beneficial for rhodamine B decomposition, and high treatment efficiency was achieved with high peak voltage and small discharge spacing. When the pH value, peak voltage and distance of pin-plate electrode is about l, 12 mm and 13.8 kV, respectively, the removal efficiency of rhodamine B was 90.8 % after 60 min treatment.
