摘　　要：为提高苯酚降解率,实验研究了脉冲电晕放电处理含苯酚废水过程中电极参数、布置方式对苯酚降解率η的影响及各参数间的关系。研究表明,通过峰值电压Up和频率f的优化组合,可获得理想的η;电极间距d和液膜厚度δ对去除效果影响明显;电极布置方式不同则处理效果不同。锥端为正极时溶液pH值和COD变化较明显;锥端为负极时η和溶液电导率σ有明显提高,利于废水的最终净化。The influence of the electrode parameters and arrangement ways on the phenol degradation rate is studied in the article, and the research tests the relationship of these parameters in the process of the pulse corona discharging. The results in this paper shows that the high degradation rate could he got by the optimum combination of voltage and frequency. It is found that the value of the electrode space and thickness of the liquid also takes place a great influence on the degradation rate. There is the best compages between the value of the voltage and frequency, also the electrode space and thickness of the liquid. There is different degradation rate in different electrode arrangement way. The pH and COD value of solution changes much obviously when the awl electrode acts as anode, whereas the degradation rate of phenol and conductivity of the solution increases distinctly when the awl acts as cathode. It is benefit for the finally decontaminate of the waste water. The results in this paper provide experimental reference for degradation of wastewater by the pulse corona discharge. It can also provide academic reference for the amplificatory experimentation of the electrode parameters and arrangement ways.
