摘　　要：利用冬天的低温条件,考察了15℃、20℃、25℃与自然温度对PAC-MBR的影响,试验结果表明,膜污染速率随着温度的下降呈现加剧趋势,15℃与自然温度的TMP之差随膜污染的增加而逐渐减少,而20℃和25℃与自然温度TMP之差均随着运行时间而增加;加温后的PAC-MBR上清液COD明显高于自然温度下的上清液COD,但是经过膜过滤后,出水COD相差无几,20℃和25℃的上清液氨氮明显低于自然温度,而出水则无明显规律。温度对微生物,特别是后生动物的种类和数量影响并不显著。Based on low temperature condition, influence on membrane bio-reactor with powder activate carbon (PAC-MBR) is studied under different, temperature. 15℃、20℃、25℃ and normal temperature respectively. The experiment shows that as the temperature drops the membrane fouling rate is raised rapidly. TMP difference between 15℃ and normal temperature lessens with membrane fouling increase. However those of 20℃ and 25℃ accelerate as membrane fouling increases. The COD value of liquid in reactor under higher temperature is distinctly higher than that in normal temperature, but there is a little difference among the effluents. The ammonia-nitrogen removal rate is sharply lower in 20℃ and 25℃ than that in the normal temperature. However, the ammonia-nitrogen of effluents is not apparent. The effects of temperature on the varieties and number of microbe are not obvious, particularly to metazoan.
