摘　　要：通过中型试验研究,获得了在不同运行参数情况下的活性污泥气浮浓缩过程曲线;提出了污泥浓缩时间在40min左右,并忽略泥水分离时间的结论,同时为气浮浓缩池的构造设计提供了依据。最后,还对试验现象进行了理论分析。A study on thickening waste activated sludge was carried out in a pilot-scale dissolved-air flotation unit. Thickening process curves in different operational parameters were obtained. The results of experiment showed that thickening time is about 40 min. , with sludge water separation time omited. Basis of design dissolved-air flotation thickener and some experimenal phe-nomina are also explained in this paper.
