Technical scheme: in order to solve above-mentioned technical problem, a kind of Novel sewage of the present invention
Process air-flotation system, it includes cesspool, agitating device, cavitation machine, slag-scraper and clear
Pond, they are linked in sequence successively, are provided with filler between described cavitation machine and slag-scraper
Formula dissolving, described agitating device, cavitation machine and slag-scraper respectively all with electric controller phase
Even, described cavitation machine is provided with the first sewage draining exit, described slag-scraper is provided with second row
Dirty mouth, described slag-scraper includes ejector, molten gas flow distribution plate and scum board, described ejector
Being located at bottom slag-scraper, described scum board is located at slag-scraper top, described molten gas flow distribution plate
It is located between ejector and scum board.
It is provided with liquid level detection device on described slag-scraper top.
It is provided with weir flow groove between described slag-scraper and clear water reserviors.
Described liquid level detection device is connected with electric controller.
Beneficial effect: compared with prior art, its remarkable advantage is the present invention: the present invention is overall
Operate steadily reliable, use electric controller so that it is integrated automation runs, improve work effect
Rate, uses material filling type dissolving, considerably increases gas and water contact area, improve gas and water
Mass transfer effect, so that molten gas efficiency reaches more than 97%, uses liquid level detector, improves control
