The present invention will be further explained with reference to the accompanying drawing.
Such as attached drawing 1, a kind of small-sized villages and small towns sewage treatment integral modular device, including water inlet pipe 5, biochemical reaction tank 6,
Sedimentation basin 13, runing rest, outlet pipe 11, aeration element 1, packing component 2, spoil disposal channel and driving equipment；It is described biochemical anti-
It answers pond 6 to share same pool wall with sedimentation basin 13 to be disposed adjacent, which offers returned sludge respectively from the bottom to top
Mouth and water outlet；The central rotating shaft of the driving equipment and runing rest is drivingly connected, and the runing rest is set up by shaft
On biochemical reaction tank 6, the runing rest be successively uniformly distributed by inner ring to outer ring be provided with distinguish with horizontal plane it is parallel
Packing component 2 and aeration element 1；The water inlet pipe 5 and spoil disposal channel are connected to biochemical reaction tank 6 respectively, the outlet pipe 11
It is connected to sedimentation basin 13.
Big feature is fluctuated for domestic sewage in rural areas water quality and water, biochemical reaction tank uses based on biofilm,
Process route supplemented by activated sludge process, therefore, in rotating body, packing component 2 has biggish half compared to aeration element 1
Diameter.
The runing rest is circular configuration, including support frame structure, fixation member 4 and shaft 15, support frame as described above knot
Structure includes several and is uniformly distributed the support column 3 being connected in shaft 15, and the fixation member 4 is circular ring shape frame, and uniform
The support column 3 of distribution is fixedly connected.
Such as attached drawing 2, the driving equipment includes motor 17 and transmission mechanism 16, the motor 17 by transmission mechanism 16 with
Shaft 15 is drivingly connected, driving runing rest rotation, to drive aeration element 1 and packing component 2 with shaft 15 for center of circle rotation
Turn.Wherein, seal assembly 14 guarantees shaft 15 and the good leakproofness of biochemical reaction tank 6.
Such as attached drawing 3,4 and 5, the aeration element 1 is with the cylinder-like structure for running through a v notch v, with the support column
3 are vertically arranged；Central angle corresponding to the v notch v of the aeration element 1It is 5~40 °；The bar shaped of the aeration element 1
The opening direction of notch is 90~125 ° with central angle θ folded by corresponding support column 3；The both ends of the notch of the aeration element 1,
Distribution is provided with laciniation along its length；The lateral wall of the aeration element 1 is provided with several thin along circular arc direction
Groove is stitched, is mutually perpendicular between the fine crack groove and v notch v.
Such as attached drawing 6, the packing component 2 includes fixing axle 18 and disc 19, and for the ease of installation, the disc 19 is divided
For several fanning strips, each fanning strip forms a module along 18 direction of fixing axle.
Such as attached drawing 1,13 bottom of sedimentation basin is inclined plate 10, and the tilt angle of the inclined plate 10 is 10~30 °.Be conducive to
Clarifier sludge flows back into biochemical reaction tank 6 along inclined plate 10 from returned sludge mouth certainly due to gravity after sinking.
Such as attached drawing 1, the upper and lower end of the water outlet is respectively equipped with deflector 9, and bootable biochemical reaction tank water outlet is along heavy
Shallow lake pond transversal cross-section is uniformly distributed.The tilt angle of the deflector 9 is greater than or equal to the tilt angle of inclined plate 10.It can prevent from giving birth to
Change reaction tank 6 and is discharged the sludge washed away on inclined plate 10.
The spoil disposal channel that 6 bottom of biochemical reaction tank is equipped with includes gate valve 7 and sludge pipe 8, due to the lower dirt of biofilm
Mud yield, 6 base sludge of biochemical reaction tank can periodically turn on gate valve 7 and be discharged by sludge pipe 8.In addition, sludge pipe 8 also doubles as
Dump pipe when biochemical reaction tank 6 needs to overhaul, can discharge sewage in pond by sludge pipe 8.
A kind of small-sized villages and small towns sewage treatment integral modular device working principle of the invention is as described below:
Sewage enters biochemical reaction tank 6 from water inlet pipe 5, and dirty Organic substance in water can pass through biomembrane in biochemical reaction tank 6
Method and activated sludge process removal.
Aeration element is carried from biochemical reaction tank into aeration element during Periodic Rotating, by sewage, aeration
Element notches guarantee that sewage can be flowed out from aeration element notch in rotation process with the fixed angle of support column, the sawtooth of notch
Structure guarantees that the sewage of overflow is cut into several threads, and the thread cut has biggish water flow specific surface area, passes through
Drop is so that sewage is oxygenated；In addition to this, slow velocity of rotation makes remaining thread along aeration element surface
The flowing of fine crack groove, extends its aerial exposure duration；Furthermore the thread through saw cut is by aeration element surface fine crack
Groove is further cut, and water flow specific surface area further increases, and improves the oxygenation capacity of sewage.
After the sewage overflow that aeration element carries is complete, air, partial air quilt after rotating are full of inside aeration element
It brings into aeration tank；With the continuation of rotation, air is constantly compressed in aeration element, and the increase of pressure promotes compressed air
Middle oxygen and the sewage entered in aeration element are accelerated in two phase-contact surface mass transfer velocities；With further rotation, aeration element
When notch turns to compressed air edge, compressed air starts to overflow from indentation, there, and the laciniation of notch cuts air
At several tiny bubbles, the mass transfer effect of bubble and water is enhanced；At the same time, the bubble constantly risen makes biochemical reaction tank
Interior sewage is further stirred.
Rotary aerating system periodically rotates, and can guarantee that sewage is sufficiently stirred in biochemical reaction tank, favorably
It is sufficiently spread in dirty water oxygen, improves aeration effect.Packing component uses the biological rotating disk of scaled down version, is conducive to biology
The ventilation of turntable, also replacement easy to disassemble, meanwhile, avoid the problems such as falling off in use using flexible filler.
Treated, and sewage is shared the water outlet under pool wall and enters sedimentation basin 13 under the guidance of deflector 9, contains mud
Sewage sludge in 13 uphill process of sedimentation basin sinks due to gravity, reflux of the sludge of sinking through inclined plate 10 and shared pool wall
Sludge mouth is back to biochemical reaction tank 6 certainly, and under the rotational agitation of the aeration element 1 and packing component 2 in biochemical reaction tank
It reenters in biochemical reaction tank 6 and is mixed with sewage.Primary water after precipitating in sedimentation basin 13 passes through overflow weir 12 and outlet pipe
11 discharges.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
