Embodiment
For structure, characteristic and effect thereof to the utility model, can have and further understand and be familiar with, lift a preferred embodiment at present, and be described with reference to the accompanying drawings as follows:
Sewage at first passes through flocculation reaction, gets into the described MULTI CONTACT air-floating apparatus of the utility model then, and shown in Fig. 1-2, this MULTI CONTACT air-floating apparatus comprises air flotation pool body and recirculation water air dissolving system.The external side of air flotation pool is provided with the dissolved air water water inlet pipe, sewage water inlet pipe and clear water rising pipe.Laterally be provided with contact reacts district 1, disengaging zone 3, the Rinsing Area 6 that is interconnected successively in the air flotation pool body, Rinsing Area 6 bottoms are provided with return line.3 bottoms, disengaging zone are provided with the perforation header 5 that communicates with Rinsing Area 6.
The recirculation water air dissolving system comprises reflux pump, dissolving, pneupress system (not shown) and the first dissolved air water reliever 2 and the second dissolved air water reliever 4.The inlet of reflux pump is connected with return line; The backflow pump outlet is connected with the water-in of dissolving; Said pneupress system is connected with the inlet mouth of said dissolving; The import of the first dissolved air water reliever 2 and the second dissolved air water reliever 4 is connected with the outlet of the dissolved air water of dissolving, and the first dissolved air water reliever 2 is positioned at 1 bottom, said contact reacts district.The second dissolved air water reliever 4 is positioned at disengaging zone 3.
Be provided with slag scraper and slag chute 7 on the said disengaging zone 3, said slag scraper comprises motor, by said motor-driven sprocket wheel and the traction scraper plate that driven by said sprocket wheel.Slag chute 7 is connected with scum pipe 8.
The implementation process of the utility model is: sewage at first passes through flocculation reaction; Get into contact reacts district 1 through sewage water inlet pipe then; With the backflow dissolved air water of zone of action reaction zone 1 and the microbubble thorough mixing of release thereof; Flco in the sewage is attached to forming air float body on the small bubbles, this air float body rises in contact reacts district 1 gradually, and gets into disengaging zone 3 through the overflow weir overflow that is arranged between zone of action and disengaging zone.After air float body gets into disengaging zone 3, through secondary air supporting, and float to Ji Zhaqu after the water sepn, and blown off to slag chute 7 by slag scraper.Clear water gets into Rinsing Area through being arranged on disengaging zone intermediary perforation header.Clear water part in the Rinsing Area gets into dissolving through reflux pump and carries out recycling, and another part is discharged by the clear water water shoot.
