Biofilm medium 5 is mounted on 4.
The centre position of framework 1 is equipped with montant, and rack 8, the top pond edge of biological contact oxidation pond 11 are equipped on montant
On motor 6 and gear 7 are installed, gear 7 is intermeshed with rack 8,6 drive gear 7 of motor rotation after, gear 7 can drive
Rack 8 is moved upwardly or downwardly with supporting rack.The both sides frame of framework 1 is equipped with multiple pulleys 10, biological contact oxidation pond
11 pool wall corresponding position is equipped with sliding rail 9, and pulley 10 is embedded in sliding rail 9, when supporting rack moves up and down, sliding rail 9 and pulley 10
Cooperation the movement of supporting rack can be oriented to and be limited.Control cabinet can also be set outside biological contact oxidation pond 11, used
In the rotation of control motor 6.
As shown in Fig. 2, biological contact oxidation pond 11 includes three independent regions, passing through passageway between two neighboring region
12 separate, and biofilm formation device has been provided independently from each region.
As shown in figure 3, multiple filler assemblies 4 are equably suspended on nylon rope.
As shown in figure 4, the circle that filler assembly 4 includes first thin slice of circle 41 that is disposed over and is arranged below
Centre bore 43 is equipped on two thin slices 42, the first thin slice 41 and the second thin slice 42, nylon rope may pass through the centre bore 43 by filler
Component 4 is connected in series with.The lower surface of first thin slice 41 is equipped with the first connecting pole 44 for extending downwardly, the second thin slice 42 it is upper
Surface is equipped with the second connecting pole 45 upwardly extended, and the first connecting pole 44 is solid cylinder, and the second connecting pole 45 is open circles
Cylinder, the first connecting pole 44 may be inserted into the hollow-core construction of the second connecting pole 45, to realize the first thin slice 41 and the second thin slice
42 connection.First connecting pole 44 and the second connecting pole 45 include six, and are distributed in M shape, every second connecting pole 45
Periphery tying-up two biofilm media 5.
Under normal operating conditions, the supporting rack bottom of biofilm formation device is directly placed into the bottom of pond of biological contact oxidation pond 11,
The biofilm medium 5 being articulated on supporting rack is sunk in water, microorganism can on biofilm medium 5 apposition growth, and with being passed through
Bio-contact oxidation reaction occurs for the oxygen contact in sewage, reaches purpose of purifying the water quality.
When damage, which occurs, in biofilm medium 5 to need repairing or replace, by the start-stop button being manually operated on control cabinet, make
Motor 6 is rotated with moving gear 7, and the pulley 10 in framework 1 slides on sliding rail 9, so as to promote supporting rack, is facilitated and is taken out biofilm Jie
Matter, and can realize separate repair in subregional or replacement；After the completion of repair or replacement, operation button makes motor 6 anti-
Turn, under the action of gear 7 and rack 8, supporting rack declines, until sewage did not had the top of supporting rack gradually, biofilm medium 5 is complete
Portion is immersed in sewage, continues to purify sewage.
Pass through the explanation to the utility model biofilm formation device and multiple embodiments of sewage disposal device, it can be seen that this reality
At least there is one or more of with novel biofilm formation device and sewage disposal device embodiment：
1st, supporting rack can move up and down relative to biological contact oxidation pond, on the one hand in repair or replacement, pass through liter
The biofilm medium or filler assembly of damage can be repaired or replaced by playing supporting rack, be not required to emptying biological contact oxidation pond
In sewage, it is not required that lower pond operation, sewage disposal device can continue to run with, and flexibility is high, and security risk is small, reduces
Labor intensity saves the cost for cultivating aerobic bacteria again, and can improve sewage treating efficiency；On the other hand, pass through liter
Descending branch support can observe the upgrowth situation of microorganism, technique can be adjusted in time when there are abnormal conditions in time, enhancing
The existence of microorganism and purification of water quality ability；
2nd, by motor, gear and rack, the raising and lowering for realizing supporting rack can be facilitated；
3rd, by sliding rail and pulley, the movement that can make supporting rack is more smooth, and can to the movement of supporting rack into
Row is oriented to and limiting；
4th, filler assembly uses the stereochemical structure of two thin slices composition, and packing specific area is big, can inhabit and carry for biology
For larger space, make more geomicrobes can be with apposition growth, thus higher concentration in biological contact oxidation pond can be maintained
Biomass；The high porosity and stereochemical structure of filler assembly can be such that waste water more easily enters inside filler assembly and be given birth to
Object contact oxidation, while but also the biomembrane normally to come off is relatively easily flowed out from filler assembly with water, reduce
The probability of occurrence that filler blocks；
5th, the filler assembly formed using two thin slices can be cut and stopped to bubble, play aerated limited device
Effect, increase the residence time of bubble and the surface area of gas-liquid contact, improve the absorbability of oxygen.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
