高压脉冲放电处理垃圾渗滤液的试验研究

Research on Landfill Leachate Treatment by High Voltage Pulse Discharge

采用高压脉冲放电产生的活性自由基处理渗滤液，研究了投加铁屑、电极间距和放电电压对去除垃圾渗滤液中COD和BOD5的影响。在电极形式为尖一尖式、电极间距4—6mm、放电电压36kV-46kV、废水体积71条件下对渗滤液进行放电试验，结果表明：投加铁屑和升高电压可提高COD和BOD5的去除量；在放电电压一定的条件下，存在最佳的电极间距。

The active free radical producing from high voltage pulse discharge was used to treat landfill leachate. The different influences of adding iron and keeping electrode distance and discharge voltage to remove COD and BOD5 are experimented. Under the condition of keeping 4 - 6mm electrode distance and discharge voltage of 24 to 48 KV, the results show that the removal amount of COD and BOD5 will increase with growing voltage and adding iron. There is an optimal electrode distance when keeping the discharge voltage.
