| 摘 要： | 采用固定化微生物曝气生物滤池（I-BAF）技术成功处理了模拟垃圾渗滤液,探讨了pH和溶解氧（DO）对系统脱氮性能的影响。结果表明,固定化微生物曝气生物滤池反应系统启动迅速,运行稳定,可以有效去除模拟垃圾渗滤液中的有机物和氨氮,其去除率分别达到97.1%和99.9%。在pH为7.5～8.5之间,DO 4.0 mg/L左右的条件下对模拟垃圾渗滤液中氮的去除最为有利,同步硝化反硝化效率以及总氮去除率均达到最高,分别为96.2%和94.3%。这主要是由于I-BAF系统中大孔载体提供了厌氧-兼氧-好氧的微环境,使硝化和反硝化反应在同一个反应器内发生,共同作用实现模拟垃圾渗滤液中总氮的去除。 |

| Abstract: | A biological treatment with immobilized microorganism was successfully developed in a biological aerated filter(I-BAF) to treat synthetic landfill leachate.The regulatory effects of pH and dissolved oxygen(DO) on nitrogen removal were investigated.It was demonstrated that the I-BAF system started up quickly and it was very efficient for COD and nitrogen removal from synthetic landfill leachate with efficiencies of 97.1% and 99.9%.When pH and DO were controlled at 7.5~8.5 and 4.0 mg/L,respectively,maximum of... |
