摘　　要：为了降低能耗和提高废水处理效果,解决臭氧在废水处理方面应用的一些实际问题,探讨了利用液电效应催化臭氧氧化废水的新工艺。用研制的一种小体积,低成本,操作方便,运行可靠的小能量脉冲功率电源进行了液电效应催化臭氧氧化处理活性艳红K2-BP水实验。实验结果表明:对4 L质量浓度200 mg/L活性艳红K2-BP溶液的处理,液电效应催化臭氧氧化比单独臭氧氧化脱色率提高了20个百分点,COD去除率提高了18个百分点;反应60 min后,活性艳红K2-BP吸收光谱的3个特征吸收峰均消失,发色基团及苯环和萘环均被打断。相同条件下脱色率达到90%,液电效应催化臭氧氧化比单独臭氧氧化电能节约41%(6.7Wh),氧气节约44%(24L)。证明此方法可提高臭氧利用率、增强染料脱色效果,减小装置体积,降低处理成本,具有良好的应用前景。In order to overcome the deficiencies in the existing technologies of industrial wastewater treatment such as untrue degradation, secondary pollution, excessive energy loss and high cost, and serve the purpose of saving treatment cost, reducing energy loss and device size and improving treatment effect, a new technology is put forward in this paper. The technology, with great original quality and technological features, is a combination of high voltage pulse discharge and ozone oxidizing. In this technology, hydro-electric effects of force, thermo, sonic and ray generated in high voltage pulse discharge are applied as catalytic method of ozone oxidization in place of UV lamp-house and ultrasonic generator etc. Therefore, an experimental pulsed power source, consisting of four parts, namely the main discharge circuit, the trigger circuit, the control circuit and the electric control part, is developed and designed on the basis of the principles of being small size, low cost, convenient operation and high operational reliability. Of the four parts, the control circuit is designed with reliable EMC, and applies the MCU as the core unit. A complete water treatment experiment apparatus is also developed. Then the pulsed power source is applied in the experiment of dye waste water treatment. The results show that the catalysis of high voltage pulse discharge in ozone oxidization improves the decolorization rate（20%） and the COD removal rate（18 %）. After 60 minutes of reaction, three characteristic absorption peaks disappear, the chromophore group, the benzene ring and the naphthaline ring are completely broken up. When the decolorization rate reaches 90% , 41% electric energy and 44% O2 can be saved. In conclusion, this water treatment method is proved to be able to improve the utilization ratio of ozone, enhance the decolorization effect, shorten the treating time, and reduce the cost.
