针-板放电等离子体反应器结构参数对甲基橙脱色反应速率常数的影响
Effects of Structure Parameters of Needle-Plate Discharge PlasmaReactor on Reaction Rate Constant of Methyl Orange Decolorization
摘要
Abstract
The needle-plate discharge plasma reactor was used to treat methyl-orange ( MO ) -containing wastewater. The effects of reactor structure parameters on the decolorization reaction rate constant of MO were studied. The experimental results show that the optimum reactor structure parameters are as follows: The discharge anode consists of 5 stainless steel needles in parallel connection with 17 mm of needle space and 2 mm of needle length, the electrode gap is 10 mm, the O2 flow is 0.18 mVh; The cathode is a 20 mesh stainless steel wire mesh work; The dielectric barrier net is set up above the anode using 5-layer stainless steel wire with 15 mm of layer distance. Under these conditions, the simulated MO wastewater with 60 mg/L of initial mass concentration can be decolorized rapidly. The decolorization rate is 97% after treating for 12 min, and the COD removal rate is 41% after treating for 30 min.关键词
