摘　　要：实验改进了一种新的简易反应器,该反应器的主要特点是没有搅拌器,通过曝气来混合活性污泥和污水。通过连续曝气和间歇曝气对生活污水的处理结果进行对比分析,从而探究不需要搅拌装置处理生活污水的可行性,以及确定本反应器的最佳曝气/停曝组合,并将节约的电能量化到经济数字上,以便为本装置的推广,尤其是在广大农村地区的使用提供可靠的理论依据。This experiment improved a new simple reactor that is different from the traditional sewage treatment device, the main feature is lack of agitator and making activated sludge and sewage mixed by aeration. The treatment effect of continuous aeration and intermittent aeration was compared to discuss the feasibility of domestic sewage treatment without agitator, and de- termine the best group of aeration/static aeration for this reactor. The saved electric energy was quantified as the economic fig- ure, which can provide reliable theoretical basis for promotion of the device, especially in rural areas.
