Background technology
With the rise of a large amount of carwash factories, the development of various wastewater from car washer recycling equipment is promoted.With regard to current city
All kinds of wastewater from car washer Treatment for Reuse equipment actualities occurred on field see, are mostly simple commonly on filter base, then through MBR
Membrane filtration goes out recycle-water, more impurity is remained on filter membrane and ultimately causes blocked, and general MBR films must change one in about two months
It is secondary and gradually smelly by the water quality of filter membrane, virus, sandworm, greasy dirt are grown, do not reach the desired effect of filtering.
Ozone has very strong oxidisability, must in the degraded sterilization process of disinfection of drinking water and advanced treatment of wastewater
It is few.However, gas-liquid mass transfer efficiency is low, poorly water-soluble turns into limitation ozonization efficiency and less economical main cause, and subtracts
Small ozone bubbles diameter increases the specific surface area that ozone gas are ducked in drink, and is the important means for improving Ozone Gas Mass Transfer Efficiency, because
This, the technology for improving Ozone Gas Mass Transfer Efficiency using microbubble technology has very important position in advanced treatment of wastewater.It is micro-
The bubble that it refers to diameter less than 50 μm that bubble is, compared to the other bubble of grade, microbubble have specific surface area higher and
Internal pressure, can increase with the diminution of bubble diameter, according to Henry rules, the bubble that volume is being shunk its dissolving
The total amount of gas, can increase with the rising of its internal pressure, be crushed as the diameter of bubble constantly shrinks, constantly in water
Dissolving, until bubble is die out, bubble of the diameter less than 50 μm can slowly reduce in water, die out below the water surface, and diameter
Larger bubble can finally be die out with quickly rising and volumetric expansion at gas-water interface.In the process, the micro- gas of ozone
Substantial amounts of free radical is inspired around bubble, and produces HTHP, the germ of absorption is killed, ozone microbubble can in water body
Retain the several months long, fully ensured that purified water water quality continues to stablize constant for a long time.
