【给排水技师论文】摘要:采用电解氧化法对垃圾渗滤液进行深度处理的研究结果表明,电解氧化过程中,nh3-n优先于cod被氧化去除;spr三元电极的处理效果优于dsa二元电极和石墨电极;酸性条件比碱性条件更有利于电解氧化作用对cod及nh3-n的去除;cl-浓度高时,有利于cod及nh3-n被氧化去除。试验得到的适宜电解氧化条件是:ph值为4、cl-浓度为5000mg/l、电流密度为10a/dm2、spr三元电极为阳极、电解时间为4h。当cod及nh3-n浓度分别为693mg/l和263mg/l时,cod去除率为90.6%,nh3-n的去除率为100%。 关键词:垃圾渗滤液 电解氧化 深度处理 中图分类号:x505 文献标识码:a 文章编号:1000-4602(2001)08-0014-04 study on electrolytic oxidation for landfill leachate treatment li xiao-ming,wang min,jiao zhi-kui,chen zhao-yi (dept.of environmental science and engineering,hunan university,changsha 410082,china) abstract:a study on electrolytic oxidation process was made for advanced treatment of landfill leachate. the result shows that in the process of electrolytic oxidation,removal of nh3-n is preferential to that of cod,and the performance of the process by using spr
