以自行设计的流态化厌氧接触生物滤床反应器，考察了沸石、陶粒两种填料以及活性污泥对于C／N为5．6～12．9的低碳源城市生活污水的厌氧处理过程脱氮除磷的效果的影响，并对影响机理进行了探讨。结果表明：沸石、陶粒和污泥反应器平均COD去除率分别为63．62％、44．50％、26．04％，填料反应器氨氮去除率为40％、总磷去除率可达20％-30％，污泥反应器则为20％和小于10％。填料厌氧生物床优于污泥法，沸石填料优于陶粒填料，沸石材料显示了良好的脱氮除磷特性。“,”Treatment of low carbon source domestic sewage with C/N ratio of 5.6 - 12. 9 by sely-designed anaerobic biological bed reactors was investigated. Two kinds of fillers, such as zeolite and ceramsite had been studied and taking the sludge as a contrast. The experimental results showed that the average COD removal rate of zeolite biological bed reached 63.62% , the ceramsite biological bed＇s 44. 50% and the sludge biological bed＇s 26.04%. The ammonia-nitrogen removal rate of the zeolite biological and ceramsite biological beds could settle at 40%. Total phosphorus removal rate of the zeolite could reach to 20% - 30% , the ceramsite biological bed was 15% - 20% , the sludge was only under 10%. The biomembrane beds is better than the sludge and the filler for zeoliteand is better than ceramsite. Zeolite materials has showed good characteristics on removal of nitrogen and phosphorus.
