Reuse pool supplies water to using water spot；The top of sterilization pool be equipped with chlorine dioxide feed bin, chlorine dioxide feed bin be equipped with display screen, two
The discharge port of chlorine monoxid feed bin is equipped with the baffle for closing the discharge port, and display screen shows the time when baffle is opened, also
Including backwashing pump, one end of backwashing pump connects sterilization pool, and the other end connects more medium filter, active carbon filter, further includes
The blower being connected with the life contact oxidation pond.The technical solution is provided with backwash structure, can be to filter just
Row backwash is to achieve the effect that clean filter.But normal filtration step need to be suspended when backwashing, sewage purification is will affect and set
Standby day-to-day operation is more suitable as the deep purifying of long periodicity.
Sewage disposal system mentioned by above scheme, has following defects that
One, only setting or not set back purge system, MBR can not effectively be rinsed, easily reduction MBR service life；
Two, by back purge system, reach the cleaning of MBR, greatly reduce the treatment effeciency of sewage-treatment plant, need to open repeatedly
It opens and closes water plug and back purge system, easily reduce the service life of water plug and back purge system.
Therefore, necessary that domestic sewage processing system in the prior art dress is improved.
Summary of the invention
It is an object of the invention to overcome defect existing in the prior art, purifying domestic sewage processing equipment is provided, it is real
Interim membrane biological reaction pond can be rinsed in present membrane biological reaction pond, not influence the normal operation of sewage treatment.
In order to realize the above technical effect, the technical solution of the present invention is as follows: purifying domestic sewage processing equipment, including successively connect

After starting sewage treatment, floating balloon inflation pump is first opened, makes floating air ring 19 full of gas.Sewage pass sequentially through into
After water pipe 1, conditioning tank 2 and biochemistry pool 3 enter membrane biological reaction pond 4, and liquid level touches film biofilter 7, unlatching is drawn water
Pump 7-5.Film biofilter 7 starts to filter work, after sewage is filtered out of membrane biological reaction pond 4 by filter membrane 7-4, successively
Water inlet 7-22, collection water passage 7-21, the cavity 7-11 that catchments, drinking-water pipe 7-3 are flowed through, into processing pond 5 is collected, finally by out
Water pipe 6 is discharged, and completes sewage treatment works.Meanwhile in membrane biological reaction pond 4 liquid level constantly rise, when liquid level touches
After film biofilter 7, since floating air ring 19 is to the Float upward function power of film biofilter 7, make film biofilter 7 with
Liquid level also constantly rises.
Along with the progress that film biofilter 7 filters, impurity screening (cotton-shaped floating material) is made constantly to be gathered in water inlet
On filter membrane 7-4 near 7-22.After having accumulated more impurity screening on filter membrane 7-4, closes floating balloon inflation and pump, in unlatching
Floating air ring aspiration pump, reduces the buoyancy of floating air ring 19, simultaneously because the gravity of mass 20 and film biofilter 7 itself
Effect, moves downward film biofilter 7 along 9 direction of sliding bar.It repeats the above steps, film biofilter 7 can be made to exist
It moves up and down repeatedly in membrane biological reaction pond 4, makes the impurity for being attached to 7 surface of film biofilter by movement drive and water flow
It acts on and falls off, realize the cleaning of film biofilter 7.
Embodiment 2
To advanced optimizing for embodiment 1, as shown in Fig. 4 to 7, embodiment 2 the difference from embodiment 1 is that, film biofiltration
It is fixed with below device 7 and is aerated flusher 8 for the film of flushing membrane biofilter 7.It includes gas collection that film, which is aerated flusher 8,
It is gas collection cavity 8-11 inside disk 8-1, gas collection disk 8-1, the upper surface gas collection disk 8-1 is connected with several collection air column 8-2, collects air column

In work, when needing to clean film biofilter 7, opening flushing air pump 8-4 makes, and extraneous gas passes through collection
Gas gas tube 8-3 successively passes through gas collection cavity 8-11 and gas collection access 8-21, and by the solarization air cap 8-22 on collection air column 8-2 into
Enter membrane biological reaction pond 4.The bubble of generation has certain impact force to the impurity screening on filter membrane 7-4 outer wall, makes to filter
Impurity falls off.When cleaning, floating balloon inflation pump can also be in off state, floating air ring aspiration pump is open state, makes film
Biofilter 7 is gradually reduced.Collection water column 7-2 is gradually arranged in the flowing water gap between collection air column 8-2, with collection water column 7-
Area increase is worn in the 2 flowing water gaps being arranged between collection air column 8-2, the gas of solarization air cap 8-22 discharge is on filter membrane 7-4
The impact force that the impurity screening of attachment has increases, and can accelerate falling off for impurity screening, improves cleaning rate.After the completion of cleaning, open
Floating balloon inflation pump is opened, floating air ring aspiration pump is closed, film biofilter 7 is gradually increasing and rinses dress far from film aeration
8 region is set, the filter contact surface of film biofilter 7 caused by collection air column 8-2 enters is reduced and filters circulating rate
It reduces and reduces.In the process of cleaning, also collection water column 7-2 can be driven to exist along with the repeatedly inflated and deflated of floating air ring 19
It is moved up and down in flowing water gap between collection air column 8-2, washes away bubble more fully to filter membrane 7-4.Filtered
Cheng Zhong, interval are once washed away filter membrane 7-4 in 2-5 minutes, and filter effect is further increased.
In the up and down motion of film biofilter 7, the hose 22 that drinking-water pipe 7-3 is connect with the cavity 7-11 that catchments, meeting
It is shunk with the rising of film biofilter 7, is drawn high with the decline of film biofilter 7, cut down drinking-water pipe 7-3's
Upper and lower displacement.Due to filtering for a long time, need that the micro- of filter membrane surface will be attached to 7 reverse cleaning of film biofilter
Wisp cleaning.Ensure to rinse air pump 8-4 to be in off state, and interlocking lever 10 slides into 9 top of sliding groove, makes film biofiltration
Device 7 is fully located at 8 top of film aeration flusher, closes water pumping valve 7-6 and suction pump 7-5, opens backwash water valve 7-8 and backwash
Water pump 7-9 will collect the processing water back suction in processing pond 5 into film biofilter 7, processing water is made to pass through backwash water pipe 7-7,
Followed by drinking-water pipe 7-3, the cavity 7-11 that catchments, collection water passage 7-21 and water inlet 7-22, enter finally by filter membrane 7-4
Membrane biological reaction pond 4.Using the back flush of processing water, deep clean is carried out to filter membrane 7-4.After completing cleaning, close anti-
Wash water valve 7-8 and backwash water pump 7-9.Such thorough cleaning carries out primary daily.
In this way, the aeration surface flushed filter membrane 7-4 by interval combines daily back flush, it can be maximum
Improve the filter efficiency of filter membrane 7-4.
