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.
