摘　　要：为研究电压对采用三维电极处处理TNT废水的影响比较了三维电极电解法和二维电极电解法处理TNT废水的效果,考察了采用三维电极电解法时不同槽电压对电解效果的影响,并对电解机理作了初步探讨.实验表明,极板间距为4cm、电动搅拌器转速250r/min、电解时间为2h时,最佳的电解槽电压为15V,此工艺条件下的CODCr、TOC的去除率分别为77.6%、62.7%。In order to study the effect of voltage on the treatment of TNT wastewater by three-dimensional electrolysis method, compared to the different result of TNT wastewater treatment by two-dimensional method and three-dimensional method. The effect of different voltage on degradation by three-dimensional electrolysis method was inspected.The experiment of three-dimensional electrolytic reactor treating TNT wastewater shows that the removal rate of TNT and CODCr are about 77.6 % and 62.7 %, respectively when voltage is 15 V, the distance of the electrodes is 4 cm, mixing rate is 250 r/min, electrolytic time is 2 h.
