Further, the packing component includes several discs and fixing axle, and several disc holdings are parallel to each other
Even to be arranged, the fixing axle is arranged through several disc centers, and the packing component lock is fixed with corresponding support column,
The fixing axle and packing component lock connection setting, make the fixing axle keep vertical fixed with corresponding support column.
Further, it is rectangular rod-like structure that the fixing axle, which is section, and the section of the packing component lock is side
Shape, the fixing axle and packing component lock agree with fixation.
A kind of rotary compound bio type sewage water treatment method, specific as follows:
Sewage is so continuous that enter in reactive tank from water inlet pipe, the certain density activated sludge of inoculation in reactive tank；
Aeration element is aerated and is stirred to sewage in reactive tank, is carried out Aerobic Process for Treatment for activated sludge and is provided oxygen:
In one rotation period, aeration element is internal first to fill water, and is carried over the water surface with the rotation of runing rest, due to exposing
Central angle θ folded by the opening direction and support column of the notch of gas element immobilizes, and rotation process notch is with respect in aeration element
The water surface constantly reduces, and the inside of aeration element carries water constantly from notch overflow；
Notch is laciniation, overflow water can be cut into several thin water flows, the thin water flow of a part is in falling process
Several tiny drops that complete are interrupted, drop is oxygenated in falling process；The thin water flow of another part is due to runing rest
With slower velocity of rotation, is flowed along on the outside of aeration element with the fine crack groove of notch vertical connection, extend it in air
In exposure duration, then, thread can be flowed along outside fine crack groove, and thin water flow is further cut thinner water flow,
And the water surface is finally dropped to, thin water flow is disconnected in falling process falls the drop to be formed and is oxygenated；
Runing rest constantly rotates, and after aeration element carrying water overflow is complete, air is full of inside aeration element, then quilt
Below band upstream face；
As the water level in aeration element constantly rises, air in aeration element is caused constantly to be compressed, air and water exist
Two phase-contact surface oxygen transfer speed are accelerated；
When the notch of aeration element is rotated to compressed air edge, air starts constantly to overflow, the sawtooth through notch both ends
Form several tiny bubbles after the cutting of shape structure, bubble in uphill process with the continuous mass transfer of water, meanwhile, it is countless to rise
Bubble constantly becomes larger in journey, and aeration pool inner water obtains to be stirred to a certain extent；
After compressed air drains in aeration element, inner filling water, at this point, aeration element, close to the water surface, one is complete
Rotation period terminate；
At the same time, packing component provides good biomembrane attachment condition, as runing rest drives packing component to turn
It is dynamic, the degradable a part of organic matter of the biomembrane of attachment；
Sewage is entered next after activated sludge process and biofilm processing by the spilling of overflow weir 6 and outlet pipe 7
Cell processing；The amount of activated sludge that treatment process generates can be discharged with the biomembrane to fall off by spoil disposal channel.
The utility model has the advantages that (1) aeration element is carried from aeration tank into aeration element during Periodic Rotating, by water,
Aeration element notch guarantees that water energy is flowed out from aeration element notch in rotation process with the fixed angle of support rod, the saw of notch
Toothing guarantees that the water of overflow is cut into several threads, and the thread cut has biggish water flow specific surface area, passes through
Drop is oxygenated；In addition to this, slow velocity of rotation makes remaining thread along the fine crack groove on aeration element surface
Flowing, extends its aerial exposure duration；Furthermore the thread through saw cut is further cut by aeration element surface fine crack
It cuts, water flow specific surface area further increases, and improves the oxygenation capacity of water.(2) after the water overflow that aeration element carries is complete, aeration element
Inside is full of air, which is brought into aeration tank after rotating；With the continuation of rotation, air quilt in aeration element
It is constantly compressed, the increase of pressure promotes the water in compressed air in oxygen and entrance aeration element in two phase-contact surface mass transfer velocities
Accelerate；With further rotation, when aeration element notch turns to compressed air edge, compressed air starts to overflow from indentation, there
Out, air is cut into several tiny bubbles by the laciniation of notch, enhances the mass transfer effect of bubble and water；It is same with this
When, the bubble constantly risen stirs aeration pool inner water further.(3) rotary aerating system periodically revolves
Turn, can guarantee that being aerated pool inner water is sufficiently stirred, and is conducive to water oxygen and is sufficiently spread, improves aeration effect.(4)
Packing component uses the biological rotating disk of scaled down version, is conducive to the ventilation of biological rotating disk, also replacement easy to disassemble, meanwhile, it avoids
The problems such as being fallen off in use using flexible filler.
