摘要
活性污泥法中,曝气效率的高低决定了处理效果和能耗.本文综合分析了国内外的曝气技术的进展、现状和问题,指出了曝气技术的发展方向、无泡曝气的意义及亟待研究的问题.
In activated sludge treatment process, aeration efficiency determines the treatment result and energy consumption.In this article, the author presents a review on the progresses , situation and problems of external and internal aeration technology.Furthermore, the authors introduced the progress of aeration technology,significance of bubbleless aeration and the problems to be researched.
