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, contact-oxidation pool 3 and the 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 side.Wherein, the water-in (i.e. the water outlet of second pond 5) of biological filter 8 is positioned at top, the water-in (i.e. the water outlet of biological filter 8) of intermediate pool 7 is positioned at bottom, the water outlet (i.e. the water-in in quartz sand filter tank 6) of intermediate pool 7 is positioned at top, and the water outlet (i.e. 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, are integratedly arranged in unified casing 21.
Biological filter 8 of the present invention 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 below filtering basin, above filtrating area, be provided with back washing device; Back washing device comprises the back suction cover 12 be arranged at above filtrate 17, and backwash water pump 13 is fixed on the upper surface of back suction cover 12, and guide shell 14 bottom face connects the outlet of backwash water pump 13; Guide shell 14 top is fixedly connected with the bend pipe 20 of two symmetries, and bend pipe 20 inserts backwash rising pipe 19 respectively, and back suction cover 12, backwash water pump 13, bend pipe 20 can be moved up and down by spring 15 with guide shell 14.
During real work, inject the sanitary sewage of water-in 1 successively through hydrolysis acidification pool 2, contact-oxidation pool 3 and second pond 5, this part is main biochemical reaction region, hydrolysis acidification pool 2 is that the macromole decomposed difficult in sanitary sewage is resolved into easily biochemical small molecules, contact-oxidation pool 3 is removed by oxidation operation easily biochemical for the overwhelming majority, second pond 5 is by remaining particulate matter, colloid, microorganism corpse carries out solid-liquid separation, base sludge 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, clear water storehouse 18 water outlet is from flowing into intermediate pool 7, then enters quartz sand filter tank 6 from intermediate pool 7 overflow, removes fine particle thing, colloid etc. thus meets reuse or emission standard; After the filter in quartz sand filter tank 6, clear water storehouse 18 water outlet is finally discharged by water outlet 11 by disinfection pool 10.
As shown in Figure 1, the water outlet of second pond 5, biological filter 8 is entered from top overflow, now back suction cover 12 is in floating state, current flow through the biofilter material of biological filter 8 from top to bottom, are provided with aerating apparatus bottom biological filter 8, and aerobic bacteria take biofilter material as carrier, be attached to biofilter material surface, the organism flowed through in the sewage of biofilter material 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 current flow through the quartz sand filter media in quartz sand filter tank 6 from top to bottom, filter, main removal fine particle thing and colloid; Finally flow out to disinfection pool 10 from bottom.Because current are all flow through filtrate 17 to filter under self gravitation, thus do not need additionally to arrange lifting water pump, reduce operating power consumption and sound pollution.
After work for some time, the more solid particulate of filtrate 17 trapped inside in biological filter 8 and quartz sand filter tank 6, have impact on filter effect, now starts backwash water pump 13, produce negative pressure instantaneously in back suction cover 12 and decline, its opening is close to above filtrate 17 and aspirates; Under negative pressure state, the dirt particle between filtrate 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 out from flowing through backwash water outlet 16.Filtrate 17 recovers filtration capacity.After backwash completes, backwash water pump 13 is shut down, and in back suction cover 12, negative pressure disappears, and under the effect of spring 15 elastic force, back suction cover 12 lifts and leaves above filtrate 17, proceeds filtration operation.
More than describing is explanation of the invention, and be not the restriction to invention, when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
