摘要:The effects of mechanical agitation on the stripping of attached-growth bio-film from ceramic particles were studied under the conditions of different agitating speeds and durations. The results indicated that the stripping efficiency of bio-film was increased with the increase of agitating speed. The highest stripping efficiencies at the low, middle and high speeds of 300, 600 and 1200 rpm/min were 16.8, 27.4 and 48.8% respectively. The increase of agitating duration can increase the stripping efficiency of bio-film. However, as the duration exceeded 90 minutes, the increase of stripping efficiency for three speeds shows no obvious change. The variation of mass fraction of small floc and the productivity of polysaccharide and protein in suspension revealed that mechanical agitation also gave rise to the release of extra-polymer substance and the disaggregation of the stripped bio-film at the time of improving the stripping efficiency of bio-film.
