摘　　要：通过中试试验对高海拔城市污水的SBBR运行特性进行了研究。试验结果显示:虽然采取了控温和加热措施,但在试验温度范围内仍不能使处理出水达标排放。当温度在10~16℃时,COD去除率达到50%左右,TN和TP去除率均在40%左右;进一步升高温度,污染物去除率逐步提升,其中TN去除率对温度的响应尤为明显。当温度在10~16℃范围内时,系统内微生物活性较低,其增殖现象减弱;随着温度进一步升高,微生物活性及其增殖现象逐渐增强,反应速率也明显加快。Research on the operation characteristics of sequencing biofilm batch reactor（SBBR） for high-altitude urban sewage has been implemented by pilot experiments. The results show that the treated effluent still cannot reach the discharge standard,though measures,including temperature control and heating,have been taken in the range of experimental temperature. When the temperature is in the range of 10-16 ℃,the removing rate of COD is around50%,and the removing rates of TN and TP are around 40%. With the further increase of temperature,the removing rate of pollutants is gradually increased,and the response of TN removing rate to temperature is especially obvious.When the temperature is in the range of 10-16 ℃,the microbial activity in the system is relatively low and the proliferation is weakened. With the further increase of temperature,the microbial activity and the proliferation rate are enhanced and reaction rate is obviously speed up as well.
