| 摘 要： | 采用填埋垃圾上层间歇曝气充氧或渗滤液回流前经好氧、硝化反应器处理的方式,营造生物反应器填埋场系统内生物脱氮环境,研究了其中生活垃圾原位脱氮的性能.结果表明,在填埋垃圾稳定化过程中,88%以上的含氮化合物以渗滤液的形式溶出.填埋垃圾上层间歇曝气充氧或渗滤液经好氧、硝化反应器处理后回流的生物反应器填埋场系统对渗滤液总氮的处理效果较好,实验结束时,渗滤液总氮量仅为对照填埋场的28.7%和14.3%.

| Abstract: | By means of intermittent aeration at the top of landfilled refuse or an aerobic nitrifying reactor using treated leachate recirculation,the environment for nitrogen removal in bioreactor landfill systems were constructed to study the performance of in Situ nitrogen removal from municipal refuse.The results showed that 88% of nitrogenous compound was released in the form of leachate during landfill stabilization.The nitrogen removal efficiency was good in the bioreactor landfill systems with intermittent aeration at the top of landfilled refuse or an aerobic nitrifying reactor using treated leachate recirculation,where the total nitrogen in leachate was only 28.7% and 14.3% of the control landfill at the end of the experiment. |
