Pond is aerated port 13-12, and biochemistry pool is aerated the lower part case 13-1 connection biochemistry pool aeration cavity 13-11 and is equipped with biochemistry pool aeration tube
13-2, biochemistry pool aeration tube 13-2 are connected with biochemistry pool aeration pump 13-3；Disinfected-decolorized pond 5 is equipped with the artificial dispensing port of disinfectant
With ozone generator 14；The connection of 2 lower part of conditioning tank is equipped with sewage pipe 15, and sewage pipe 15 is equipped with blowdown valve 15-1；In conditioning tank 2
It is additionally provided with filtering grid 16, sewage enters after conditioning tank 2 flows into biochemistry pool 3 by filtering grid 16 again.Ozone generator 14
Model is preferably MTS-CFG-50A.
At work, sewage flows into conditioning tank 2 by water inlet pipe 1, by filtering grid 16, by the biggish impurity mistake of volume
Filter is gradually gathered in the other side of filtering grid 16 in 2 side initial filter sewage of conditioning tank.When initial filter sewage level reaches certain height
Biochemistry pool 3 is flowed into after degree.Meanwhile sewage is constantly assembled in conditioning tank 2, the partial sludge in sewage can gradually be deposited in adjusting
2 bottom of pond.When sludge settling for a period of time after, open blowdown valve 15-1, so that sludge and partial impurities is passed through sewage pipe 15 and be discharged.
After initial filter sewage enters biochemistry pool 3, biochemistry pool aeration pump 13-3 is opened, and put into biological bacteria, make gas successively
Port 13-12 is aerated by biochemistry pool aeration tube 13-2, aeration cavity 13-11 and biochemistry pool and enters biochemistry pool 3, to initial filter sewage
It is aerated, and is sufficiently mixed biological bacteria with initial filter sewage, and oxygen needed for providing enough reactions to biological bacteria, given birth to
Change combined sewage.Biological bacteria by after the substance biochemical reaction in sewage to COD, BOD5, SS, TP, NH in sewage3- N, TN etc. are real
Now effective removal.Biochemical combined sewage is continuously increased, and after its liquid level reach a certain height, flows into membrane biological reaction pond 4, into
Row filtering, resulting drainage of crossing are evacuated to disinfected-decolorized pond 5.Drainage has been served as into investment disinfectant and ozone behind disinfected-decolorized pond 5
Generator 14 carries out disinfection fade treatment to drainage investment disinfectant is crossed.It is resulting after disinfected-decolorized processing to handle water well
It is discharged finally by outlet pipe 6.
Embodiment 4
To advanced optimizing for embodiment 3, as shown in Figure 8-9, embodiment 4 and the difference of embodiment 3 are, are located at film
The gas collection gas tube 8-3 of vertical direction is equipped with flexible pipeline section 8-31 in biological reaction pool 4, and its outer cover is equipped with flexible protection
Mesh enclosure 17, the pipeline section 8-31 that stretches are located in flexible protection net 17, and flexible 17 bottom end of protection net is fixed at membrane biological reaction
4 bottom surface of pond, flexible 17 top of protection net are fixedly connected on gas collection gas tube 8-3；Flexible pipeline section 8-31 is bellows, by can
It shrinks highdensity material to be made, material is preferably thermoplastic polyurethane elastomer rubber (TPU).Elevator is used at work
When structure, if without gas in driving air bag 10, the pipeline section 8-31 that stretches is contraction state with flexible protection net 17；Conversely, flexible
Pipeline section 8-31 and flexible protection net 17 are to draw high state.Flexible protection net 17 plays protection to flexible pipeline section 8-31 and makees
With.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
