摘　　要：以西安思源学院的生活污水为处理对象,探讨了基于颗粒污泥活性再生的生物造粒流化床污水处理系统相对于传统污水处理工艺在去除效果和经济上的优势。该工艺增加了曝气外筒,这一构造上的改变使得混凝吸附的颗粒污泥在外筒得以再生,同时对有机物与氨氮等具有很好的去除效果,内筒的混凝造粒TP的去除率高达90%以上,内外筒的好氧与缺氧交替的环境对TN的去除率也较高。该工艺具有很好的抗冲击负荷能力,占地少,运行费用合理,特别适合用于分散式污水处理。In this paper, the advantages in removal efficiency and economy of the fluidized pellet system which is based on the activity regeneration of granule sludge were compared to the traditional wastewater treatment studies for the treatment of the domestic wastewater of Xi＇ an Siyuan University. Owing to adding an aerobic column, the activity of granule sludge which is formed in the inner col- umn is regenerated in the outer column, while there is higher removal efficiencies of COD and NH4 - N. The removal efficiency of TP can reach to 90%. The two stages of aerobic column and an- oxic column can be beneficial in the removal of TN. The favorable endurance of shock loading and small footprint and good effluent make fluidized pellet bioreactor（FPB） a good choice for the decentralized treat- ment technology for the small amount of domestic sewage.
