The utility model relates to the field of
water treatment equipment, in particular to a multiphase flow micro-nano air floatation
ultrafiltration device which comprises a
water treatment box body, an equipment area is arranged at the bottom of the
water treatment box body, and a water inlet area, a
flocculation area, a water distribution area, a contact area, an air floatation area and a separation area are sequentially arranged at the top of the water treatment box body from left to right. A multi-phase flow micro-nano bubble generation
system is arranged in the equipment area, a bubble release
pipe is fixedly connected to the bottom of the air floatation area, the multi-phase flow micro-nano bubble generation
system is connected with the air floatation area through the bubble release
pipe, a
slag collection box is fixedly arranged on one side of the water treatment box body and communicates with the separation area, a plurality of
ultrafiltration membrane boxes are fixedly arranged in the separation area, and the
ultrafiltration membrane boxes are communicated with the air floatation area. A
slag scraping mechanism is fixedly arranged at the top of the separation area, a driving mechanism is fixedly arranged at the top of the
slag collecting box, the driving mechanism controls the slag scraping mechanism to operate, and the device has the advantages of being good in air flotation effect, simple in structure and small in occupied area.
