Description
Technical field
The present invention relates to water treatment facilities, especially a kind of water process flotation tank.
Background technology
Air supporting starts from ore dressing flotation technology as a kind of efficient, quick solid-liquid separation technique, it is passed through largely toward water
Intensive microbubble makes it be adhered to each other with impurity, wadding grain, forms whole floating body having a specific gravity smaller than that of water, and make it by buoyancy
The water surface is floated up to, to complete the water purification technology of solid separation.Initially, which it is close to be mainly used for fat, oil, fiber, grease etc.
Degree is less than the removal of the substance of water, and in later stage the 1960s, this technique is pushed away in sewage disposal and drinking water treatment
Extensively, it is widely used to the industry such as oil refining, papermaking, printing and dyeing, electric power, chemical industry, weaving, leather, food, machinery, light industry at present
In the processing of waste water and city domestic sewage and Drinking Water.Different according to the mode for generating bubble, air-float technology is divided into
Be electrolysed (cohesion) air supporting, be aerated air supporting and air-dissolving air-float, wherein pressurized dissolved air flotation technique be the most common technique of water process it
One.
Pressurized dissolved air flotation technique is divided into downflow type air-float technology and counter-current air floating technique at present.Downflow type air-float technology
It is that raw water is made to be contacted in the same direction with dissolved air water in contact chamber by the way of fair current, microbubble is with suspended matter in contact chamber
It moves in the same direction and completes collision and adhesion process.Counter-current air floating technique is to make raw water in contact chamber by the way of adverse current
Inversely contacted with dissolved air water, microbubble and raw water reverse flow, the water outlet of contact chamber bottom, the suspended matter of decline with it is upper
The microbubble risen inversely contacts, and microbubble is made to be collided with suspended matter.In counter-current process, microbubble is effectively touched with suspended matter realization
It hits, the flow dynamic that adhesion process need not be too big, but is in turbulent condition, flow dynamic is big, touches since raw water flows downward
Microbubble after hitting does not adhere well to be formed after stable bubble flco or adherency in raw water counter flow action with suspended matter
Phenomenon is desorbed in lower generation, causes bubble flco that cannot complete floating separation process well, occurs " running alumen ustum ' phenomenon.
However, either using the flotation tank of downflow type air-float technology and counter-current air floating technique, the control to bubble velocity
System is all particularly important.Cross it is slow then so that contact dynamics of the bubble with suspended matter only, it is difficult to suspended matter is combined, it is too fast again
Bubble can be caused to be detached from again with suspended matter, it is difficult to play the purpose of water process.
