磁场协同交变脉冲电化学场处理垃圾渗滤液

以自行研制的交变脉冲电源为基础,在自制的磁场-电化学场一体化水处理反应器中,使用铝片为可溶性电极,并同时施加磁场和交变脉冲电解电流,对垃圾渗滤液进行处理.在磁感应强度为0.08 T,脉冲峰值电流密度为5 A/dm2,平均脉冲峰值电压为2.0 V,脉冲电流周期为3 s及处理时间为90 min的工艺条件下,相对于相同电化学条件的单一交变脉冲电絮凝处理,新鲜垃圾渗滤液的COD_Cr与NH₃-N的去除率分别提高了8.41%和6.56%;老龄垃圾渗滤液的COD_Cr与NH₃-N的去除率分别提高了16.01%和7.82%.表明磁场与电化学场的协同作用明显地提高了废水的处理效果. 

The Cooperation of Magnetic Field and Periodic Electrochemistry Field to Degrade Landfill Leachate

In the water treatment reactor of magnetic field and electrochemistry field which was manufactured by the authors themselves, aluminum soluble electrode was used to treat landfill leachate by periodic magnetic field and pulse electrolysis. It is shown that when the maximal instantaneous density is 5 A/dm^2 , cycle for changing the pole is 3 seconds, the intensity of magnetic field is 0.08 T, and the response time is 90 minutes, the degradation effect of magnetic-field cooperation with electric field is better than the single electric field. To the fresh landfill leachate, the removal rate of CODCr and NH3-N improves by 8.41% and 6.56% respectively. To the aged landfill leachate, the removal rate of CODCr and NH3-N improves by 16.01% and 7.82% respectively. The cooperative effect of periodic magnetic field and electrochemistry field distinetly can obviously improve the effect of waster water treatment.
