摘要
采用模拟污水,通过厌氧-好氧交替过程研究了活性污泥生物除磷过程。在实验过程中,通过周期性通入空气和氮气的实验方法,采用气升式环流反应器和普通鼓泡塔进行对比,在研究反应器的传质性能的基础上,进一步对反应器内的活性污泥形态和生物除磷性能进行了观察和测定。实验表明,相对于普通鼓泡塔,动态气升式环流反应器对活性污泥的生物除磷过程有明显的强化作用,磷的去除率提高了30%。
The anaerobic\|aerobic process of biological phosphorus removal of activated sludge is studied by simulating sewage.In the experiment,the process of biological phosphorus removal and morphology of activated sludge are investigated based on the study of mass transport process in airlifted loop reactor and bubbling reactor by passing air and nitrogen periodically.The results show that the airlifted loop reactor is more effective in the process of biological phosphorus removal than bubbling reactor,and the phosphorus removal efficiency increased 30%.
