为了提高生化池曝气过程中氧的转移率、降低曝气能耗,本文基于微孔曝气清水性能实验研究,通过调整实验过程中的参数,来探讨合适的曝气方式,从而达到节能降耗的目的.实验通过对2种不同类型的微孔曝气器分别在不同的通气量下确定合适的曝气量,在此基础上进行了不同周期的间歇性曝气充氧实验.实验数据表明:当曝气量从1 Nm3/h增大到2.5 Nm3/h时,2种类型的曝气盘均在1.5 Nm3/h处氧的转移率和动力效率达到最大值,即1.5 Nm3/h为本实验连续曝气的最佳曝气量;再在此基础上进行间歇性曝气实验,氧的转移率和氧的动力效率均在间歇性曝气周期为0.1s时达到最大值.分析表明:间歇性曝气方式较连续曝气方式,氧的利用率提高了50％以上,氧的动力效率提高了60％以上,从而大幅度减少了电能的消耗,为活性污泥好氧生化处理系统工艺提供了新的研究思路.“,”To improve the transfer rate of biochemical oxygen tank aeration and reduce the energy consumption,the effects of multi-parameter setting on fine bubble aeration performance is carried out.First,optimal aeration flux is obtained by two fine bubble aerators' tests under continuous aeration condition,and then six different intermittent aeration experiments are conducted.Experimental results show that the best continuous aeration flux is 1.5Nm3/h since the transfer rate of oxygen and the power efficiency of the aerators are highest at 1.5 Nm3/h when the aeration flux is increased from 1 Nm3/h to 2.5 Nm3/h.Second,intermittent aeration on these two aerators are conducted.Results show that,the transfer rate of oxygen and the power efficiency is better than other conditions when the period of intermittent aeration is 0.1 s.The oxygen utilization and power efficiency of intermittent aeration with 0.1 s period increase by more than 50％ and 60％,respectively,those of continuous aeration.Hence,intermittent aeration could reduce the power consumption significantly,and reduce the operating costs of aerator system.It is meaningful for aerobic activated sludge biological treatment system processes.
