摘　　要：通过实验确定低温（8~15℃）条件下气提式接触氧化反应器挂膜启动期填料生物膜量SS、生物活性ρ（VSS）/ρ（SS）的具体变化过程,研究反应器在低温8~15℃条件下对生活污水的COD、NH3-N、TP处理效果,并与常温（16~28℃）条件进行对照。结果表明,在低温条件下,气提式接触氧化反应器填料挂膜成功需要18 d,COD、NH3-N、TP去除率平均达到83.1%、69.9%、20.9%;COD、TP的去除效果受温度影响最小,出水除TP外均达标。气提式接触氧化反应器是一种很好的小型低温生活污水处理装置及工艺,对低温环境适应强。In the low temperature （8-15 ℃）, specific changes in biofilm quantity SS, the biological activity of VSS/SS value in start-up process stage of airlift contact oxidation reactor were determined. Treatment effects of reactor at low temperature on domestic wastewater COD, ammonia nitrogen, and TP were compared with normal temperature （16-28℃）. The test results show that, in the low temperature 8-15 ℃, airlift contact oxidation reactor biofilm was success after 18 d, the average removal rate of COD, NH3-N and TP reached 83.1%, 69.9% and 20,9%. The removal effect of COD and TP is affected by temperature minimum; the effluent quality reached the standard except for TP. Airlift contact oxidation reactor is a very good kind of low temperature sewage treatment device and process, and which has low temperature environment adaptability.
