摘　　要：考察了添加腐殖土的SBR工艺处理生活污水的效果,并与传统SBR反应器进行对比。结果表明,腐殖土SBR工艺对有机物、NH4+-N和TP的去除率分别为85%、83%和72%,与传统SBR工艺相比,提高了对有机物的降解速率,且添加腐殖土有助于SND现象的发生,从而提高了对氮的去除率。腐殖土的添加缩短了SBR系统的有机物氧化和氨氮硝化的时间,对于提高处理效率和降低运行费用具有重要意义。The treatment efficiency of domestic sewage by the SBR filled with humus soil was investigated and compared with that by the conventional SBR. The results show that the removal rates of organic matters, NH4^＋-N and TP by the SBR filled with humus soil reach 85% , 83% and 72% respectively. Compared with the conventional SBR, the degradation rate of organic matters is improved, and the addition of humus soil contributes to occurrence of SND, thus the removal rate of NH4^＋- N is increased. The addition of humus soil shortens the oxidation time of organic matters and the nitrification time of NH4^＋-N, which can improve the treatment efficiency and reduce the operation cost.
