摘　　要：采用序批式生物膜反应器对生活污水的一级出水进行了脱氮处理,探究该装置对化学需氧量(COD)、氨氮和硝酸盐氮的去除性能及其对温度、pH和溶解氧等环境因素的影响。结果表明:该装置可完成快速启动过程,且最终出水的COD、氨氮去除能力达到了88.24%±3.63%、80.17%±10.54%,硝酸盐氮的最终出水量仅为(2.40±0.43) mg/L,说明该装置拥有良好的COD和氮去除能力。该装置的主要环境限制因素为温度,其他因素(pH和溶解氧)设定均较为合理,可促进该装置脱氮。Sequencing batch biofilm reactor has been adopted for denitrogenation treatment of primary effluent of domestic sewage,it is explored effects of the device on chemical oxygen demand,the remove performance of ammonia nitrogen,temperature,pH value,dissolved oxygen and the other environmental factors.Results show:Quick start can be finished by the device,and the final removal results of COD,ammoina nitrogen out of the water can reach to 88.24%±3.63%,80.17%±10.54%,the amount of nitrate nitrogen out of the water only was(2.40±0.43)mg/L,it illustrated the device has good removal ability for COD and nitrogen.Main environmental limiting factor of the device is temperature,the setting of the other factors(pH and dissolved oxygen)are all more reasonable,it can promote denitrogenation of the device.
