The present invention can also have another kind of scheme: the device of iron in a kind of the dewatering, comprise water inlet pipe, rising pipe and purifying vessel, purifying vessel is made of first purifying vessel and second purifying vessel, be provided with membrane separation assemblies and gas distribution pipe in first purifying vessel, rising pipe links to each other with hollow-fibre membrane endoporus in the membrane separation assemblies, and gas distribution pipe is positioned at the below of hollow-fibre membrane; Be provided with aeration tube in second purifying vessel, aeration tube links to each other with gas distribution pipe and communicates with air pump, links to each other with return line with reflux pump between two purifying vessels.
In above-mentioned two kinds of technical schemes, according to actual needs, membrane separation assemblies and gas distribution pipe can have a plurality of.Hollow-fibre membrane can be microfiltration membrane, nanofiltration membrane or ultra-filtration membrane, and its material can be any in polypropylene, polyvinylidene difluoride (PVDF), the polyethylene.
The present invention has following beneficial effect:
1, the combination of aeration assembly and membrane separation assemblies can delay the obstruction of film, and can reduce the concentration of pollutents such as iron in the water, turbidity, organism effectively.
2, water outlet high-quality is stable, and by the adjusting process parameter, applicable to different water sources, the anti impulsion load ability is strong.
3, economized out filtrate and ripening stage thereof, water outlet is quick, is suitable for emergent the use.
4, equipment is small and exquisite, flexible, is fit to very much use under the motor-driven situation.
