Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, integrated domestic sewage treatment device described in the utility model 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.
Biological filter 8 of the present utility model is biofilter material and quartz sand filter media with the filtrating area filtrate 17(in quartz sand filter tank 6 separately) be all positioned at filtering basin below, above filtrating area, be provided with back washing device; Back washing device comprises the back suction cover 12 that is arranged at filtrate 17 tops, and backwash water pump 13 is fixed on the upper surface of back suction cover 12, and guide shell 14 bottom faces connect the outlet of backwash water pump 13; Guide shell 14 tops are fixedly connected with the bend pipe 20 of two symmetries, and bend pipe 20 inserts respectively backwash rising pipe 19, and back suction cover 12, backwash water pump 13, bend pipe 20 can move up and down by spring 15 with guide shell 14.
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 taking 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 to explanation of the present utility model, is not the restriction to utility model, and without prejudice to the utility model spirit in the situation that, the utility model can be done any type of amendment.
