Lower edge is bent towards center water-locator 12, makes scum silica frost be not easy to flee from.The inside of center water-locator 12 is the first reative cell 19, folding
The inside of flowing plate 4 is the second reative cell 13.The bottom of center water-locator 12 is communicated with former pond 1, water inlet pipe by inlet channel
Grug feeding jar 2 and elevator pump 6 are provided with road, grug feeding jar 2 is two, and one of grug feeding jar 2 is used to add aluminium polychloride
(PAC), another grug feeding jar 2 is used to add polyacrylamide (PAM), and Flow-rate adjustment is provided between grug feeding jar 2 and inlet channel
Valve 3, PAC pharmaceutical quantities and PAM pharmaceutical quantities are can adjust by adjusting flow control valve 3.Elevator pump 6 is preferably multiphase flow pump.Center
The bottom of water-locator 12 is communicated with Airfloat pump 17 by aerated conduit.The bottom of pond body 11 is tapered enriched chamber 14, taper
Enriched chamber 14 help to collect and floccule body and discharge, the bottom of pond body 11 is communicated with sludge pump 18, spoil disposal by spoil disposal pipeline
The end of the preferably airlift pump of pump 18, scum pipe 10 and spoil disposal pipeline is communicated to body refuse pond 5.The top of pond body 11 is provided with triangle
Weir effluent trough 9, triangular-notch weir effluent trough 9 are communicated with outlet pipe 16.
The operation principle of the present embodiment is：PAC medicaments and PAM medicaments enter center water-locator 12 with elevator pump 6, and
Raw water in inlet channel and the first reative cell 19 and in former pond 1 is mixed and produces floccule body, and Airfloat pump 17 is aerated, gas
Bubble carries tiny scum silica frost and floccule body enters the second reative cell 13, and scum silica frost gradually moves up, finally will in the presence of Slag Scraping Device 7
Scum silica frost scrapes dreg-inlet hopper 8, then scum silica frost is discharged by scum pipe 10 under gravity.Floccule body enters under flow action and divided
From room 15, under gravity, precipitation enters enriched chamber 14 to floccule body, and the clear water on upper strata then enters three by overflow after separation
Angle weir effluent trough 9, is then discharged by outlet pipe 16.Floccule body after accumulation certain amount, opens sludge pump in enriched chamber 14
