摘　　要：采用有弹性填料ABR和无弹性填料ABR研究不同温度下弹性填料对ABR处理生活污水的影响。结果表明,随着温度的降低,有弹性填料ABR(HABR)与无填料ABR对COD和SS的平均去除率均出现下降,但HABR对COD和SS在各温度下去除率均高于ABR;两组ABR对氮磷的去除率较低,且都随温度下降而降低。弹性填料有助于ABR提高COD和SS的去除率和抗低温性能,对氮和磷的去除率影响较小。Using ABR with elastic filler and ABR without elastic filler,the effect of elastic filler on ABR treatment of domestic sewage were investigated,under different temperatures.The result showed that with the decrease of temperature,the average removal rate of COD and SS decreases with elastic filler ABR(HABR)and non-filled ABR,but the removal rate of COD and SS at each temperature is higher than that of ABR.Group ABR had a low removal rate of nitrogen and phosphorus and both decrease with decreasing temperature.The elastic filler helped the ABR to improve the removal rate and low temperature resistance of COD and SS,and had little effect on total nitrogen and total phosphorus removal rate of ABR.
