Skill.Concurrent air floatation machine generally comprises flocculation tank, contact chamber and separate tank.Sewage is introduced into flocculation tank and flocculation
Agent is sufficiently mixed generation flocculation reaction, Nian Jie with minute bubbles completion in dissolved air water subsequently into contact chamber, forms edge after bubble flco
The inclined-plane set between contact chamber and reaction tank enters separate tank and floats up to liquid level, forms scum silica frost and excludes.Bubble exists with particle
Collision and adhesion process, microbubble and the sewage co-flow flowed up, contact of the bubble with suspended matter are completed in contact chamber
Time is shorter, and the adhesion effect of bubble is poor, particularly when the relatively more and looser flco feelings of Oil in Sewage Water or suspended particulate
Condition.
Counter-current air floating device generally sets up level-one contact chamber, wherein upward microbubble and the raw water to flow downward carry out
The flowing of opposite direction, the suspended matter of decline are inversely contacted with the bubble risen, bubble is adhered to suspended matter, during micro- gas
Bubble can complete good collision process with particulate matter, but due to the downward flow force effect of raw water, microbubble cannot with particle
Adhesion is formed well occurs desorption phenomenon under the action of raw water out-phase flow force after stable bubble flco, or adhesion,
The bubble flco of formation cannot complete floating separation process well.
