摘要
结合羟基自由基活性氧高级氧化技术处理垃圾渗滤液的工程应用,探讨了化学沉淀-混凝与超声-活性氧氧化联合作用处理垃圾渗滤液的预处理过程,并优化了工艺操作参数,最终使得垃圾渗滤液处理结果为COD总去除率为62% ~ 65%,NH3-N去除率为65%~70%,色度降低96%,并大大消除了臭味,为后续生物处理打下了良好基础.
Based on the application of hydroxyl-radical-activated-oxygen advanced oxidation technology in the treatment of landfill leachate,the synergistic effect of chemical precipitation-coagulation and activated oxygen-ultrasonic oxidation on the pretreatment of landfill leachate is studied.The process operating parameters are also optimized.Under the optimal condition,the total removal rate of COD and NH3-N are 62%-65% and 65%-70%,respectively.The chromaticity can be decreased by 96% and its smell is greatly eliminated.It makes a good foundation for subsequent biological treatment.
