3.2.3 Response relationship between microbubble size and
Microcystis size
The particle size ratio distribution of adhered Microcystis and
microbubbles is shown in Fig.6 A). The particle size ratio ofMicrocystis and microbubbles is in the range of
0~4.2. When the ratio of the two is between 0 and 1.2,
with the increase of the ratio, the proportion of
microbubble-Microcystis in this range increases from 0.5% to 22.1%.
When the ratio increases from 1.2 to 4.2, the proportion of
microbubble-Microcystis in this range gradually decreases. With the
ratio exceeding 2.7, the proportion is less than 2%. From the
cumulative percentage, the cumulative ratio in the range of
0.6~1.5 is as high as 63%, and the cumulative curve
rises slowly when the ratio is greater than 1.5. When the size ofMicrocystis is 0.6~1.5 times the size of
microbubbles, Microcystis is easily adhered by microbubbles, and
the adhesion rate is as high as 63%. Among them, the probability of
adhesion is the highest when the ratio is between
0.9~1.2.
