A novel pulse discharge system for water treatment was constructed, which can be easily submerged in water. It consists of a stainless screw bar used as the high voltage electrode, a stainless spiral wire used as the earth electrode, and an air disperser placed under the electrodes. The frequency of discharge was drastically decreased with increase of solution conductivity, and no discharge plasma was observed when the conductivity was1200 μS/cm. The decomposition of indigocarmine and linear alkylbenzene sulfonate (LAS) was also demonstrated with this novel discharge plasma reactor. Inactivation profiles of microorganisms by submerged style pulse discharge system in bubble water were investigated. We have confirmed the inactivation of Escherichia coli and Bacillus subtilis spore by this system.

构建了一种新型的脉冲放电水处理系统。它由用作高压电极的不锈钢螺杆、用作接地电极的不锈钢螺旋线和放置在电极下方的空气分散器组成。随着溶液电导率的增加，放电频率急剧下降，当电导率为1200 μS/cm时，没有观察到放电等离子体。利用这种新型的放电等离子体反应器对靛蓝胭脂红和直链烷基苯磺酸盐（LAS）进行了降解实验。研究了浸没式脉冲放电对气泡水中微生物的灭活特性。我们已经证实了该系统对大肠杆菌和枯草芽孢杆菌孢子的灭活作用。
