【摘要】In order to treat landfill leachate of low C/N ratio economically and effectively ,the shortcut nitrification denitrification process was adopt .Experiment was operated by controlling temperature and DO .And the influence of temperature and DO was analyzed by dynamics .The experiment and analysis results showed that : the optimum DO concentration was 3 mg ? L -1 , the optimum operation temperature was 28 ℃ to shortcut nitrification reaction of low C/N landfill leachate .%为了对低C/N的垃圾渗滤液进行经济、有效的脱氮处理,采用短程硝化反硝化工艺,对温度和DO两个主要影响因素进行了实验分析.从动力学方面,分析了其对短程硝化的影响.研究结果表明:低C/N垃圾渗滤液短程硝化反应的最佳运行DO浓度为3 mg?L -1,最佳运行温度为28℃.
