| 摘 要： | 采用自制的针一筒电极脉冲高压放电装置进行水中高压放电诱导产生H2O2和O3的实验,研究了电极间距,放电电压,放电时间,放电方式曝气条件等因素对诱导产生H2O2和O3的影响,同时对放电过程能耗及其效率进行了研究.结果表明:电极间距和放电时间对产生H2O2和O2的浓度有较大影响,放电电压和放电方式影响不大.曝气条件下进行高压放电时,水中会产生NO2ˉ,NO2ˉ等阴离子,水体系pH降低,电导率增大.放电过程能量有效利用率为88.3%.

| Abstract: | The experiment of producing of H2O2 and O3 through pulsed high voltage discharge in water was carried out by meants of a home-made apparatus with two electrodes of needle and ballon shape.The effect of some conditions such as the gap of electrodes,the voltage,the discharge time,water treatment style and the exposed treatment on the producing ofH2O2 and O3were studied.The results showed out that the gap of electrodes and the discharge time had a marked influence on the H2O2 and O3 concentrations in water,but... |
