Carry out it is secondary pneumatically supported the reason is that: microbubble and particle complete collision and adhesion process in air bearing reaction tank 5, when the two contacts
Between it is short, cause that bubble wadding body adhesive efficiency is low, bubble wadding body adheres to unstable problem, during steep flocs float, it is easy by
The interference of resistance to water-flow causes purifying water effect undesirable so that microbubble-particle is desorbed.Secondary air-dissolving air-float is carried out, it is micro-
Bubble is adhered to each other with steady particle is just taken off, the bubble wadding body formed at this time, and microbubble is often inside bubble wadding body, and then gas is micro-
Bubble-particle is copolymerized and forms bigger bubble wadding body greatly, and the bubble wadding body air content formed at this time is big, and the bubble wadding body of formation is more tied
Real, microbubble desorption is more stable, and purification of waste water effect is more preferable.
