| 摘 要： | 采用铁促电解法处理垃圾填埋场渗滤液;考察了FeSO4浓度、初始pH值、电流(电压)对污染物去除的影响.结果表明,与传统电解氧化降解有机物相比,铁促电解显著提高了有机污染物的去除效率;FeSO4浓度越大,有机物去除效果越高;电解介质合理的初始pH值为3.0～4.0;铁促电解对渗滤液CODCr与NH3-N的去除率分别为68.37%,89.07%,色度和浊度的去除率大于98%.

| Abstract: | Iron promoted electrolysis technique was adopted to treat the landfill leachate and the influence of FeSO4 concentration, initial pH value and electrolytic current (electrolytic voltage) on the removal of contaminants was inspected. The iron promoted electrolysis enhanced markedly the removal efficiency of contaminant, compared with the traditional electrolysis oxidation degradation of organism. The greater the FeSO4 concentration, the higher the removal effect of organism; the reasonable initial pH value of electrolysis medium was 3.0~4.0; the removal efficiencies of leachates CODCr and NH3-N by iron promoted electrolysis were 68.37 % and 89.07% respectively, and the removal efficiency of color and turbidity exceeded 98%. |
