Description
Technical field
The present invention relates to a kind of processing garbage leachate air floatation machines, belong to high concentration hard-degraded organic waste water processing equipment
Field.
Background technique
The percolate that domestic waste generates during landfill is high with organic pollutant concentration, ammonia nitrogen concentration is high,
The features such as concentration of heavy metal ion is high, processing difficulty are very big.For dirty containing a large amount of suspended matters and macromolecular mass in Leachate site
The feature for contaminating object, is suitable technology path using air flotation technology.
Traditional common sewage treatment air floatation machine, since the residence time is short, dissolved air water reflux ratio is mismatched, and is not suitable for
In the processing of garbage leachate.
Summary of the invention
The object of the present invention is to provide a kind of processing garbage leachate air floatation machines, can effectively remove coagulation in Leachate site
The suspension colloid generated after reaction, pollutant removal are significant.
The technical solution of the present invention in order to achieve the above objectives is: a kind of processing garbage leachate air floatation machine, including cabinet,
Water inlet, dissolved air release, water inlet distributor, the area Rong Qi baffle, dissolving, air dissolved pump, molten gas connecting tube, return water connecting tube,
Dross skimming baffle, liquid level regulator, slag scraper, slag-discharging device, water outlet repair evacuation port, dissolved air water regulating valve.
Water inlet is located at air bearing box body front, and the Leachate site of coagulant and flocculant is added, is imported into through water inlet
Water inlet distributor.
The clear water that air floatation machine generates is sucked in air dissolved pump by air dissolved pump by return water connecting tube according to reflux ratio (0.3-0.6),
Dissolving is injected after being mixed into air, and after being sufficiently mixed in dissolving, dissolved air release is delivered to by molten gas connecting tube.
It is come into full contact with from water distributor outflow sewage with the dissolved air water flowed out from dissolved air release in the air floatation machine bottom of box, by
Step rises, and crosses the area Rong Qi baffle, realizes mud-water separation, and supernatant dross is scraped by slag scraper and air bearing is discharged into slag-discharging device
Machine, after the clear liquid below dross crosses dross skimming baffle, through liquid level regulator overflow to air bearing box body rear portion, finally by going out
Air floatation machine is discharged in the mouth of a river.
Periodically air floatation machine is discharged by maintenance evacuation port in the sludge of bottom of box deposition.
The balance that user can adjust valve regulation dissolved air release by dissolved air water discharges.
Detailed description of the invention
The embodiment of the present invention is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of structural schematic diagram for handling garbage leachate air floatation machine of the present invention.
Wherein: 1-cabinet, 2-water inlets, 3-dissolved air releases, 4-water inlet distributors, the 5-area Rong Qi baffles, 6-
Dissolving, 7-air dissolved pumps, 8-molten gas connecting tubes, 9-return water connecting tubes, 10-dross skimming baffles, 11-liquid level regulators,
12-slag scrapers, 13-slag-discharging devices, 14-water outlets, 15-maintenance evacuation ports, 16-dissolved air water regulating valves.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of processing garbage leachate air floatation machine, including cabinet
1, water inlet 2, dissolved air release 3, water inlet distributor 4, the area Rong Qi baffle 5, dissolving 6, air dissolved pump 7, molten gas connecting tube 8, time
Water connecting tube 9, dross skimming baffle 10, liquid level regulator 11, slag scraper 12, slag-discharging device 13, water outlet 14 repair evacuation port
15, dissolved air water regulating valve 16.
As shown in Figure 1, water inlet 2 is located at 11 front of air bearing box body, the Leachate site of coagulant and flocculant is added,
Water inlet distributor 4 is imported into through water inlet 2.
The clear water that air floatation machine generates sucks air dissolved pump 7 by return water connecting tube 9 by air dissolved pump 7 according to reflux ratio (0.3-0.6)
In, it is mixed into after air and injects dissolving 6, and after being sufficiently mixed in dissolving 6, molten gas is delivered to by molten gas connecting tube 8 and is released
Put device 3.
Sewage is flowed out from water distributor 4 sufficiently to connect with the dissolved air water flowed out from dissolved air release 3 in 1 bottom of air bearing box body
Touching, gradually rises, and crosses the area Rong Qi baffle 5, realizes mud-water separation, and supernatant dross is scraped by slag scraper 12 into slag-discharging device 13
Air floatation machine is discharged, after the clear liquid below dross crosses dross skimming baffle 10, through 11 overflow of liquid level regulator to air bearing box body 1
Finally air floatation machine is discharged by water outlet 14 in rear portion.
Periodically air floatation machine is discharged by maintenance evacuation port 15 in the sludge of bottom of box deposition.
The balance that user can adjust dissolved air release 3 by dissolved air water regulating valve 16 discharges.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
Protection scope, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all include
Within protection scope of the present invention.
