Further improvement as technique scheme:
Described back washing device comprises the back suction cover that is arranged at filtrate top, and backwash water pump is fixed on the upper surface of back suction cover, and guide shell bottom face connects backwash water pump outlet; Guide shell top is fixedly connected with bend pipe, and bend pipe inserts respectively backwash rising pipe, and back suction cover, backwash water pump, bend pipe and guide shell can move up and down by spring.
Described hydrolysis acidification pool, contact-oxidation pool, second pond, biological filter, intermediate pool and quartz sand filter tank are close to successively, integrated being arranged in a unified casing.
In described casing, be also provided with sludge sump and Ventilator Room.
Beneficial effect of the present invention is as follows:
The present invention is by being integrated into tank type biological filter and tank type strainer in preorder treatment facility, form integrated treatment facility, make current each functional zone of naturally flowing through from top to bottom, without lift pump is additionally set, biological filter and filtrating area are without the pipeline that valve and connection are set, consistence and the globality of equipment are fully guaranteed, can carry out rapidly scene installs, also carry out easily buried, reduce floor space, simplified control mode, reduced work energy consumption and sound pollution, be conducive to form the standard prod of modularization, mass.
Filtrating area is arranged on filtering basin below by the present invention, above filtrating area, is provided with the back washing device of back suction cover, can automatically carry out backwash to filtrate in time, to recover the filter effect of filtrate after work for some time.This is simple and compact for structure, and after directly using, the water purification in road can carry out backwash, thereby without the required water source of complicated back suction pipeline and backwash is set; And can carry out in the intervals of business backwash, and after finishing, backwash can resume work immediately, guarantee the continuity of work.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, integrated domestic sewage treatment device of the present invention comprises the hydrolysis acidification pool 2, the contact-oxidation pool 3 and second pond 5 that are linked in sequence, road after the water outlet of second pond 5, be disposed with biological filter 8, intermediate pool 7 and quartz sand filter tank 6, the water outlet in quartz sand filter tank 6 is finally discharged by water outlet 11 by disinfection pool 10, and Ventilator Room 9 is positioned at disinfection pool 10 1 sides.Wherein, the water-in (being the water outlet of second pond 5) of biological filter 8 is positioned at top, the water-in (being the water outlet of biological filter 8) of intermediate pool 7 is positioned at bottom, the water outlet (being the water-in in quartz sand filter tank 6) of intermediate pool 7 is positioned at top, and the water outlet (being the water-in of disinfection pool 10) in quartz sand filter tank 6 is positioned at bottom.Hydrolysis acidification pool 2, contact-oxidation pool 3, second pond 5, sludge sump 4, biological filter 8, intermediate pool 7 are close to successively with quartz sand filter tank 6 and Ventilator Room 9, integrated being arranged in unified casing 21.
When real work, the sanitary sewage that injects water-in 1 passes through hydrolysis acidification pool 2 successively, contact-oxidation pool 3 and second pond 5, this part is main biochemical reaction region, hydrolysis acidification pool 2 is the small molecules that the difficult macromole decomposing in sanitary sewage resolved into easy biochemistry, contact-oxidation pool 3 is by the easily oxidation operation removal of biochemistry of the overwhelming majority, second pond 5 is by remaining particulate matter, colloid, microorganism corpse carries out solid-liquid separation, bottom mud is promoted to sludge sump 4 by air-lift device, supernatant liquor gravity flow enters biological filter 8, biological filter 8 is to the further biochemical treatment of remaining organism, impel organic pollutant up to standard.After the filter of biological filter 8,18 water outlets of clear water storehouse, from flowing into intermediate pool 7, then enter quartz sand filter tank 6 from intermediate pool 7 overflows, meet reuse or emission standard thereby remove fine particle thing, colloid etc.; After the filter in quartz sand filter tank 6,18 water outlets of clear water storehouse are finally discharged by water outlet 11 by disinfection pool 10.
As shown in Figure 1, the water outlet of second pond 5, enter biological filter 8 from top overflow, now back suction cover 12 is in floating state, flow through the from top to bottom biofilter material of biological filter 8 of current, 8 bottoms, biological filter are provided with aerating apparatus, and aerobic bacteria is take biofilter material as carrier, be attached to biofilter material surface, the organism in the sewage of the biofilter material of flowing through is removed by aerobic bacteria; Then water outlet enters intermediate pool 7 from bottom.The water outlet of intermediate pool 7 enters quartz sand filter tank 6 from top overflow, and flow through the from top to bottom quartz sand filter media in quartz sand filter tank 6 of current, filters, and mainly removes fine particle thing and colloid; Finally flow out to disinfection pool 10 from bottom.Because current are all that the filtrate 17 of flowing through under self gravitation filters, thereby do not need lifting water pump is additionally set, reduced work energy consumption and sound pollution.
After work for some time, filtrate 17 trapped inside in biological filter 8 and quartz sand filter tank 6 more solid particulate, affected filter effect, now start backwash water pump 13, interior moment of back suction cover 12 produces negative pressure and declines, and its opening is close to filtrate 17 tops and aspirates; Under negative pressure state, the dirt particle that filtrate is 17 is all inhaled into back suction cover 12 and guide shell 14, and is expelled to backwash rising pipe 19 by bend pipe 20 and flows automatically and flow out by backwash water outlet 16.Filtrate 17 recovers filtration capacity.After backwash completes, backwash water pump 13 is shut down, and the interior negative pressure of back suction cover 12 disappears, and under spring 15 elastic force effects, back suction cover 12 lifts and leaves filtrate 17 tops, proceeds filtration operation.
More than describing is explanation of the invention, is not the restriction to invention, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
