CAF工艺浓缩剩余活性污泥的可行性研究

Feasibility Study of Thickening Waste Active Sludge by Cavitation Air Flotation

涡凹气浮已广泛应用于工业废水和城市污水的预处理中,但涡凹气浮在污泥处理中尚没有应用。根据课题组两年多在南昌朝阳洲污水处理厂的试验表明,涡凹气浮可用于浓缩城市污水处理厂的剩余活性污泥,特别是低浓度剩余活性污泥的浓缩。

It is widely used in industrial waste water and city sewage treatment by Cavitation Air Rotation. But, it is still not be used in sludge treatment by Cavitation Air Flotation. With the result of the experiment we have done in the Sewage Treatment Plant of Nanchang Chaoyangzhou for more than two years, we know clear that： It is available to thickening waste active sludge especially thicking low concentration waste active,sludge by Cavitation Air Flotation.
