项目摘要

The decomposition of phenol which is one of hardly decomposable organic substances in the water using plasma-ultrasonic hybrid process is investigated. In order to confirm the effect of plasma-ultrasonic hybrid process on the phenol removal, the experiments of phenol removal using pulsed discharge plasma treatment, ultrasonic treatment, and simultaneous treatment of pulsed discharge plasma and ultrasonic are performed. When the gas-liquid interface pulsed discharge plasma is used, the phenol removal efficiency using simultaneous treatment of pulsed discharge plasma and ultrasonic is almost the same as that using pulsed discharge plasma treatment. The phenol is hardly removed using an ultrasonic treatment. On the other hand, when the pulsed discharge plasma in liquid is used, the phenol removal efficiency of simultaneous treatment of pulsed discharge plasma and ultrasonic reaches 78.9% and it is higher by 14.8% than that of pulsed discharge plasma treatment.

研究了等离子体-超声波组合工艺对水中难降解有机物苯酚的降解。为了验证等离子体-超声波复合工艺对苯酚的去除效果，进行了脉冲放电等离子体处理、超声波处理以及脉冲放电等离子体和超声波同时处理苯酚的实验研究。当使用气-液界面脉冲放电等离子体时，使用脉冲放电等离子体和超声的同时处理的苯酚去除效率与使用脉冲放电等离子体处理的苯酚去除效率几乎相同。使用超声波处理几乎不能除去苯酚。另一方面，当使用液体中的脉冲放电等离子体时，脉冲放电等离子体和超声波同时处理的苯酚去除效率达到78.9%，比脉冲放电等离子体处理的苯酚去除效率高14.8%。
