| 摘 要： | 利用高压脉冲放电等离子体技术对TNT模拟废水进行降解,研究了放电次数、电极间距、放电电压、电导率对TNT降解效果的影响.结果表明:对TNT的降解率随着放电次数的增加和电压的升高而提高.在放电电压为36kV的条件下,降解率最佳时的电极间距为6mm.电导率的增加会导致放电减弱,对TNT的降解率下降.在放电电压为36kV、电极间距为6mm、初始浓度为50 mg/L的条件下,7L的TNT模拟废水经过300次放电后降解率达87%.经GC/MS分析,废水中的TNT降解彻底,同时有直链烷烃和含苯环类有机物生成. |

| Abstract: | The high voltage pulse discharge plasma technology was used to degrade synthetic TNT wastewater,and the influence of discharge times,electrode distance,discharge voltage and conductivity on the degradation efficiency of TNT were investigated.The results show that TNT degradation rate increases with increasing of discharge times and voltage.When the discharge voltage is 36 kV,the electrode distance for optimal degradation rate is 6 mm.With increasing of conductivity,the discharge effect is weakened,and TNT d... |
