The motor is connected with stirrer paddle by a rotary shaft, and the aeration tank bottom is provided with aeration tube, the aeration tube external one
Air blower.
After opening air blower, the gas distributing pipeline of aeration tank bottom starts to supply, and the bubble of formation is by micro- in activated sludge
Bio-absorbable, while also improve the dissolved oxygen of waste water.The power supply of mixer is then turned on, control electric current, regulates rotation blade
Rotating speed, blade rotation produces very big motive force, and this motive force is promoted below blade to activity more than aeration tank bottom
Sludge, flow downward, after encountering aeration tank bottom plate, then to surrounding diffusion, eventually arrive at aeration tank topmost surface.Pass through aeration tank
Blade stirring inside the pipeline gas distribution of bottom and aeration tank, the region sludge that can not be touched to aeration tube gas distribution, is had
The agitation of effect, solve in aeration tank and aeration dead angle occur, form sludgd deposition region and anaerobism occurs so that sludge blackening,
It is smelly.
On the basis of using above-mentioned technical proposal, the utility model can also use technical scheme further below：
The mixer is installed on above aeration tank by the way that screw is detachable, and the mixer is provided with two and two stirrings
Machine is symmetrical arranged, and is fully stirred so that the sludge in pond body reaches.Meanwhile it is detachably connected convenient installation, maintenance and changes.
It is connected between the collecting-tank and aeration tank with the first pipeline, the first pipeline one end is connected with collecting-tank bottom,
The other end is passed through in aeration tank above aeration tank；Elevator pump is additionally provided with first pipeline.
The aeration tank and the top of sedimentation basin are equipped with effluent trough.
It is connected between the aeration tank and sedimentation basin with the second pipeline, the effluent trough phase of the second pipeline one end and aeration tank
Even, the other end is passed through in sedimentation basin.
The effluent trough of the sedimentation basin is also associated with outlet pipe.
The sedimentation basin bottom of pond is provided with the sludge pipe being passed through in aeration tank, and the sludge pipe is provided with sludge reflux pump,
To carry out secondary use.
The utility model has the advantages that：
1. without more technological processes are produced, simply original traditional aeration tank is added and this enters, only needed
To be goed deep into an aeration tank motor installed above by power transmission shaft below the liquid level of aeration tank, with turning inside aeration tank
Dynamic blade is connected.And mixing plant is easy for installation, maintenance and maintenance are simple, alleviate worker and aeration tank base sludge is entered
The workload of row recoil.
2. the electric current of stirring motor can be adjusted, rational electric current number can be set, reaches optimal velocity of rotation, makes
To stir dynamics in aeration tank moderate, the zoogloea of aeration tank activated sludge will not be destroyed because rotating speed is too fast.
3. in relatively low aeration quantity, the subregion in aeration tank has sludgd deposition.After stirring, can compared with
Under low dissolved oxygen, keep the sludge in aeration tank persistently to turn over and gush, improve muddy water Combination character.
4. the rotation for rotating blade is passed through in the region below aeration tube, after producing downward thrust so that be aerated bottom
Sludge can be disturbed in time, the problem of efficiently solving the deposition of aeration tank bottom.
Brief description of the drawings：
Fig. 1 is a kind of structural representation of the aeration pool device of band stirring of the utility model.
Wherein, collecting-tank 1, aeration tank 2, sedimentation basin 3, elevator pump 4, sludge reflux pump 5, air blower 6, outlet pipe 7 are electronic
Machine 8, rotary shaft 9, stirring blade 10, aeration tube 11.
Embodiment
With reference to accompanying drawing, a kind of aeration pool device of band stirring provided by the utility model is described further.
As shown in figure 1, a kind of aeration pool device of band stirring, including successively with the collecting-tank 1 of pipeline connection, aeration tank 2,
Sedimentation basin 3.
It is connected between collecting-tank 1 and aeration tank 2 with the first pipeline, the first pipeline one end is connected with the bottom of collecting-tank 1, separately
One end is passed through above aeration tank 2 in aeration tank 2, and elevator pump 4 is additionally provided with the first pipeline.
It is connected between aeration tank 2 and sedimentation basin 3 with the second pipeline, the effluent trough phase of the second pipeline one end and aeration tank 2
Even, the other end is passed through in sedimentation basin 3.The outside of aeration tank 2 has air blower 6 to connect aeration tube 11 by pipeline, pacifies above aeration tank
Equipped with motor 8, motor 8 connects stirrer paddle 10 by rotary shaft 9.
The effluent trough of sedimentation basin 3 is also associated with outlet pipe 7, and sludge reflux pump 5 is arranged at the bottom of sedimentation basin 3.
Carrying out practically method is as follows：
1）It is in collecting-tank 1 that industrial wastewater is quenched uniformly, industrial wastewater is delivered to by aeration tank 2 by elevator pump 4；
2）Industrial wastewater is thoroughly mixed in aeration tank 2, and the aeration tube 11 of bottom is connected with air blower 6, aeration tube
11 the insides spray air, are sufficiently contacted and reacted with the mud mixture in aeration tank 2；
3）Exported by the air quantity of air blower 6, control the dissolved oxygen in aeration tank 2, and the aeration degree of aeration tank 2.
When the aeration quantity in aeration tank 2 is smaller, it may appear that the sedimentation of sludge, stirring dynamics are inadequate.When the aeration quantity in aeration tank 2 compared with
When big, it may appear that the overexposure phenomenon of sludge, influence the water outlet of sedimentation basin 3 band mud below.When being run at aeration tank 2, Ke Yi
In the case of low air quantity, using agitating function, accomplish that the sludge of aeration tank 2 is not in substantial amounts of sedimentation, avoid that work can not have been exposed
The phenomenon of property sludge；
4）The motor 8 above aeration tank 2 is opened, drives stirrer paddle 10 to rotate by power transmission shaft 9, stirrer paddle 10 produces
Raw downward motive force, the sludge for disturbing bottom are dug upwards；
5）Mud mixture in aeration tank 2, sedimentation basin 3 is flow to by pipeline, mud-water separation is carried out in sedimentation basin 3, on
Clear liquid is outside the remover of outlet pipe 7.The activated sludge of the bottom of sedimentation basin 3, a part are used as excess sludge, are delivered to mud processing
Equipment, another part are delivered to aeration tank 2 as returned sludge with sludge reflux pump 5.
Embodiment one, to verify the validity of the device, the plant running half a year, treatment effect is evaluated.
In operation, the activated sludge concentration of aeration tank 2 will not be reduced gradually, and sludge concentration is also from original for aeration tank 2
1.5mg/L brings up to 2.1mg/L, and sludge concentration remains that this is horizontal.The dissolved oxygen change of aeration tank 2 is little, former
First aeration tank 2, the morning are dissolved in 0.61 or so, and the air quantity of a regulation air blower 8, the dissolving in afternoon will be increased to 3.20
Left and right, human users are frequent, are difficult to control again.The present dissolving of aeration tank 2 maintains essentially in 1.50 or so, moreover, air blower 8
Air quantity do not have to frequently adjustment.SV30 in aeration tank 2 is also reduced to current 45%, the character of activated sludge from original 85%
It is obviously improved, substantially increases the ability of the biochemical degradation industrial wastewater of aeration tank 2.
Embodiment above is only the preferred embodiment of this creation, all in this wound not to limit this creation
