摘要: 以畜禽废水为处理对象，将序批式运行模式应用到好氧三相内循环生物流化床中，考察在不同模式下的处理效果及氮的转化情况。实验结果表明，在室温条件下，进水COD浓度为2 000 mg/L左右，总氮为140 mg/L左右时，保持溶解氧在2～2.5 mg/L，交替好氧/缺氧运行方式处理效果优于单一的好氧/缺氧方式；模式为3 h（曝气）-1.5 h（停曝）-1.5 h（曝气）-1 h（停曝）时系统对总氮和氨氮处理效果最好，总氮去除率达到90%，系统主要脱氮方式为同步硝化反硝化和短程硝化反硝化。

Abstract: The three-phase internal-recycle aerobic biological fluidized bed was applied to treat the livestock wastewater,the removal efficiency and transformation of nitrogen in different modes were researched. At room temperature，the COD, the TN and the dissolved oxygen of influent were kept about 2 000 mg/L，140 mg/L and 2～2.5 mg/L,respectively, the treatment efficiency of an alternative aerobic and anaerobic mode was superior to that of a single aerobic or anaerobic mode.The mode with 3 hours aeration + 1.5 hours anaerobic + 1.5 hours aeration + 1 hour anaerobic had the highest removal rate of TN (about 90%) among the investigated three modes. The main ways for nitrogen removal in SBBR include simultaneous nitrificationdenitrification and the shortcut nitrificationdenitrification.
