  • 摘要: 针对课题组自主研发的环形推流反应器,采用校园学生宿舍生活污水作为原水,研究了持续稳定运行的条件下,反应器在夏季(高温)和冬季(低温)时对污染物的去除效果。结果表明,实验条件下,与夏季相比低温段系统COD、TN、NH3-N和TP的去除率分别降低了1.39%、7.40%、4.91%和4.78%。系统活性污泥的脱氢酶活性随着温度的下降也有降低,低温时好氧区、厌氧区和缺氧区的平均DHA分别是高温时的62%、82%和73%,反应器污染物去除效果与活性污泥脱氢酶活性具有一定相关性。
    Abstract: The removal effects of pollutants in summer (high temperature) and winter (low temperature) of the circular plug-flow reactor using the campus sewage as the raw water were studied.The experimental results demonstrate that comparing with the results in summer,the removal rate of COD,TN,NH3-N and TP in the system decreased by 1.39%,7.40%,4.91% and 4.78%,respectively in winter.Meanwhile,with the temperature decreasing,the average value of dehydrogenase activity (DHA) of activated sludge also declined.Comparing with the value in high temperature,the average value of DHA in aerobic,anaerobic and anoxic zones of the reactor at low temperatures decreased by 62%,82% and 73%,respectively.The obvious correlation can be seen between the removal efficiency of pollutants with the circular plug-flow reactor and DHA of activated sludge.
