摘　　要：采用自主研制的高压灭弧旋转火花隙开关,运用高压脉冲低温等离子技术,考察了峰值电压、初始放电电容、溶液初始pH值及TiO2的添加量对甲基橙模拟废水去除率的影响.实验表明:甲基橙的去除率随峰值电压的增大而增大,能量效率随初始放电电容的增大而提高,且TiO2的添加有效地提高了降解效率.当电源电压为13kV,pH为2时,通气处理10min,甲基橙的去除率可达96%以上.Using high-voltage pulse discharge plasma technology to process methyl orange with self-de- veloped high-pressure are rotating spark gap switch. According to the change of decolorization, the effects of peak voltage, the initial discharge capacity, initial pH value and the added amount of TiO2 on the decol- loration were studied. The results showed that the decoloration rate of methyl orange solution was in- creased with increasing peak voltage. Energy efficiency increased with the increase of the initial discharge capacity increase when the voltage rised to 13 kV, aerated 10 min, the decolorization aboved 96%.
