Fig. 2 is the top view of the utility model；

Fig. 3 is the side view of the utility model.

Specific embodiment:

Further details of elaboration is made to the utility model with reference to the accompanying drawing.

Refering to fig. 1 to Fig. 3, sewage treatment unit, including cabinet, the bottom of box is equipped with chassis 91, is used for and placement The ground of cabinet is isolated, and aeration cabinet 2, settling tank 3 and the water storage tank 4 separated by partition 1 is equipped in the cabinet；Cabinet 2 is aerated to have There is sewage inlet 21, a flushing water inlet 25 can connect sewage inlet pipe by sewage inlet 21, place in aeration cabinet 2 Active sludge bacteria (figure is not marked)；Many-sided ball built in settling tank 3 (schemes not mark) filler, is disposed with biomembrane on the many-sided ball； The one oxygenation pipe of the connection of water storage tank 4, oxygenation pipe are accessed from 4 top ventilation mouth 41 of water storage tank；The aeration cabinet 2, settling tank 3 and Water storage tank 4 is equipped with corresponding respective valve 22,31,42, and collects and 5 row of being connected to of an emptying pump after valve 22,31,42 Put mouth 6.

In actual use, electric cabinet 92 can be used, switch control is carried out to each pump housing, oxygenation pipe, emptying pump 5 etc..

In the present invention, the activated sludge bacteria placed in the aeration cabinet 2 is agglomerating to be formed as flocculence is with viscous Property wadding body adsorb organic substance.Organic substance is cleared up under conditions of oxygenation becomes harmless carbon dioxide and water, it is living simultaneously Property sludge bacteria is bred and is cultivated.

The settling tank 3 is because being full of biomembrane on filler many-sided ball, aeration waste water is when flowing through object filming, organic substance quilt Further clearing up the sludge settling object accumulated in settling tank 3 at harmless carbon dioxide and water and showy fine slag can be by Above settling tank 3 be equipped with aeration cabinet 2 communicate stripping reflux pipe 32 send back to aeration cabinet 2 in, flow back it is bigger so that treated Water quality is more stable.The stripping reflux pipe 32 provides power by air pump 93.

Treated sewage supernatant flows into the water storage tank 4, and again through being oxygenated in water storage tank 4, deep oxidation is simultaneously Deposit is in water storage tank 4, and emptying pump 5 starts after liquid level attains to a high place, and soiling solution is discharged, such as liquid superelevation, then alarm sound.

Further, as the improvement to embodiment, the valve set by aeration cabinet 2, settling tank 3 and water storage tank 4 is come together in One macerator pump 23 is released after the crushing of macerator pump 23 by mud discharging mouth 24.Lead to back in addition, being equipped in 24 side of mud discharging mouth It is aerated the circulation line 94 of cabinet 2, circulation line 94 is controlled by a pipe valve 95.

It is aerated cabinet 2, settling tank 3 and water storage tank 4 after used a period of time, openable valve 22,31,42, through crushing Sediment in 23 three cabinets of extraction of pump is given off by mud discharging mouth 24 after crushed.It can play the role of maintenance device.

Further, as the improvement to embodiment, a membrane module 7 is additionally provided between the emptying pump 5 and discharge outlet 6, The membrane module 7 is external MBR film.It is directly entered in membrane tube by the supernatant that emptying pump 5 is got, under the driving of pressure Carry out UF membrane.

The side of the membrane module 7 is additionally provided with film and rinses water inlet 71.

Further, as the improvement to embodiment, a ultraviolet light is additionally provided between the membrane module 7 and discharge outlet 6 and is disappeared Malicious sterilizer 8 is connected, and the ultraviolet sterilizing device 8 is made of body, ultraviolet germicidal lamp.By 7 film process of membrane module Water afterwards enters ultraviolet sterilizing device 8 by water inlet, is flowed through with certain speed from ultraviolet sterilizing device 8, ultraviolet Line bactericidal lamp generates high-intensitive ultraviolet light, is irradiated to the water body flowed through, when bacterium, germ and other sick bodies in water body When receiving the ultraviolet light irradiation of doses, intercrescence maincenter DNA internal structure is destroyed, thus make individual death, thus Achieve the purpose that water disinfection.
