Technical field
The utility model relates to a kind of sanitary sewage and Industrial Wastewater Treatment equipment, and the biological respinse of particularly a kind of activated sludge process and microbial film phase structure is handled waste fitment.
Background technology
Film biological contact oxidation metallization processes is developed by biological filter and contact aeration oxidation pond and comes, and as far back as the thirties in 20th century, the type of production device occurs in the U.S..Enter the seventies, appearance along with the straight honeycomb pipe filler and the three-dimensional corrugation plastic filler of wide aperture, high specific area, the range of application of biological contact oxidation metallization processes is widened, it not only can be used for handling sanitary sewage, and can be used for handling high concentrated organic wastewater and poisonous and hazardous trade effluent, compare with the other biological treatment process and represented superiority.China began the biological contact oxidation metallization processes is studied in the seventies, and first industrial experimentation device is used for Treating Municipal Sewage, all obviously had been better than activated sludge process aspect treatment effect, power consumption, economic benefit and the management maintenance.A large amount of practices surplus in the of 10 year have subsequently been carried out continuous innovation to aspects such as the kind of the kind of the structure formation of oxidation pond, filler and mounting means, air feeder and arrangement forms.
The biological contact oxidation pond organigram is seen Fig. 3 at present.As seen from the figure, this contact-oxidation pool is made up of parts such as pond body, filler and support, aerating apparatus, Inlet and outlet water device and spoil disposal pipelines.How rounded the pond body is, rectangle or square.Packed height is 3.0～3.5m in the pond, and bottom gas distribution floor height is 0.6～0.7m, and water layer 0.5～0.6m is stablized at the top, and total height is about 4.5～5.0m.Filler can be divided into suspension type filler, floating filler and consolidate three types of shape block fillers.Air feeder is by gas blower air feeder and hydrojet air feeder.The gas blower air feeder is made up of parts such as gas blower, gas pipe line and aerators.Gas blower has two types: Root's blower and multistage centrifugal blower.Aerator is by three types of boring aeration device, turbulent flow type aerator and micro-hole aerators.
Present contact-oxidation pool generally adopts the single flow contact-oxidation pool, be characterized in directly at filler bottom aeration, on filler, produce upward flow, microbial film is subjected to impact, the stirring of air-flow, acceleration comes off, upgrades, make microbial film often keep higher activity, and avoid the generation of latch up phenomenon.But the defective of its existence mainly contains:
1, aerator is contained in below the filler, and maintenance difficult is made troubles in necessary emptying pond to maintenance when the aerator damage needs maintenance to change.
2, deadweight damage filler support because of wet filler takes place in regular meeting during the emptying of pond.
3, to be located at the bottom available depth of aeration tank often be 3～4.5m to the aerating apparatus of this pond shape.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and aerator is easy to maintenance, can strengthen the deep layer shunting outer circulation bio-reactor of reactor significant depth.
The technical solution adopted in the utility model is as follows:
A kind of deep layer shunting outer circulation bio-reactor, it is characterized in that it include between and outer room, carry biomembranous filler and be contained in outer room, the bottom between interior is equipped with jet aerator, interior between and have the slit on the sidewall between the outer room.
Leave the gap between the filler in the described outer room and the outer wall of outer room, be provided with water leg on the outer side wall top of outer room, water leg is communicated with the bottom of outer room by filler and the gap between the outer room outer wall.
Described jet aerator is made up of suction chamber and mixing section, and injector head is positioned at suction chamber, and the sidewall of suction chamber is provided with gas inlet, and mixing section is a tubular cavity, and suction chamber is communicated with an end of mixing section, the bottom between the other end of mixing section is positioned at.
The bottom that described outer room is positioned at the filler below is skewed, and its outside is higher than in the inner part to be located.
The beneficial effects of the utility model have:
Compare with other aeration modes, under identical Fan Equipment and treatment effect condition, the reactor degree of depth can be increased to 7～8m, maximum can reach 9m, can save aeration tank land used 30～40%, and significantly increase bubble and sewage duration of contact, improve the utilization ratio 6～8% of oxygen.
Jet aerator in the utility model is neither a kind of bubble diffusing apparatus, neither a kind of mechanical aeration equipment, but marginal a kind of aerator, utilize the principle of ejector suck air, make ejector eject the mixed solution of air and sewage, sewage is carried out oxygenation and stirring, have simple in structure, movement-less part, nothing wearing and tearing, reduced investment, adopt self-priming aeration can cancel blower fan, thereby abate the noise pollution.

Fig. 3 is the structural representation of present bio-contact oxidation.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, it is made of the utility model 1 and two outer room 2 between interior, 1 both sides between in two outer rooms 2 lay respectively at, carrying biomembranous filler 3 is contained in the outer room 2, partly microorganism grows in filling surface with biomembranous form set, interior between in 1 microorganism grow in the water with the form that the wadding dress suspends.Filler in the outer room 2 adopts specific surface area big, the material that voidage is high, and its surface potential is high more, and wetting ability is good more, and the tack of microorganism is strong more.1 bottom is equipped with jet aerator 4 between interior, as shown in Figure 2, jet aerator 4 is made up of suction chamber 7 and mixing section 8, injector head 9 is positioned at suction chamber 7, the sidewall of suction chamber 7 is provided with gas inlet 10, mixing section 8 is a tubular cavity, and suction chamber 7 is communicated with an end of mixing section 8,1 bottom between the other end of mixing section 8 is positioned at.Between interior 1 and outer room 2 between sidewall on have the slit, air and sewage enter in the suction chamber 7 from the gas inlet 10 and the injector head 9 of jet aerator 4 respectively, between in entering after in suction chamber 7 and mixing section 8, mixing 1, through the intense reaction between interior of the sewage after jet aerator 4 oxygenations, carry out the transfer of oxygen between interior, then sewage again slowly between interior 1 and outer room 2 between slit on the sidewall flow in the outer room 2, fully contact with microbial film with the filler 3 in the outer room 2, by outer room and interior between slit on the sidewall carry out outer circulation, make sewage repeatedly carry out the transmission and the contact process of oxygen repeatedly, help the microbial growth breeding, make pollutants in sewage obtain degraded.The utility model outer room 2 and interior between the slit offered on the sidewall between 1 twice are up and down arranged, slit, top 1 passage that enters outer room 2 that is sewage between interior, slit, its underpart is the passage between in sewage is back to from the outer room bottom, forms the outer circulation fluidised form thus.The mixed solution that refluxes mixes the effect of playing diluting high-concentration sewage with former water, helps water conditioning.
Leave gap 5 between filler in the utility model outer room 2 and the outer wall, and on the outer side wall top of outer room 2 water leg 6 is set, water leg 6 is communicated with the bottom of outer room 2 by filler and the gap 5 between the outer room outer wall.The bottom that outer room 2 is positioned at the filler below is skewed, and its outside is higher than in the inner part to be located, and the water after the processing rises in the water leg 6 through gap 5, and therefrom discharges.
Other undeclared part that the utility model relates to is same as the prior art.
