Abstract
With under aerator for oxygen supply and mixing, an integrated domestic sewage treatment device consists of an oil and slag separating tank, an adjusting chamber and a SBR biological contact tank. The aerobic nitrification and hypoxic denitrification are realized with no machine room and no voice pollution. The air intake is arranged in the adjusting chamber to reduce the odor spillover. With submersible sewage pump for draining, the device has advantages of simple structure, and table and reliable property. The draining is not influenced by the deep bury of the equipment. The remained sludge is reserved and digested by the oil and slag separating tank, which makes the daily manual operating projects less. The drainage treatment of equipment is capable of achieving the first standard requires of State Standards for Comprehensive Discharge of Wastewater (GB8978-1996).
Description
Technical field
Utility model relates to integrated domestic sewage treatment device, be suitable for especially using, as the sanitary sewage in the less place of the water yields such as village, rural area, holiday village, hotel, Expressway Service or the processing of other kin organic waste waters away from the place of municipal drainage pipeline.
Background technology
At present, known integrated domestic sewage treatment device all adopts the catalytic oxidation treatment process, because the sedimentation effect of second pond is bad, excess sludge is not effectively addressed, cause treatment effect bad, be difficult to the stable requirement that reaches " waste water comprehensive discharge standard " secondary standard (GB8978-1996).And it is pretty troublesome to change filler, can not denitrogenation, and the scope of application is limited to.
Summary of the invention
Utility model is to provide a kind of processing efficiency height, energy denitrogenation, strong to water quality and quantity variation adaptability, operational management is simple, need not to dispose the concrete management personnel, the requirement of " waste water comprehensive discharge standard " primary standard (GB8978-1996) be can stable reach, the sanitary sewage of the less water yield and the treatment facility of kin organic waste water adapted to.
Utility model is established in one with 3 oil removals every slag bath, 1 equalizing tank and 1 SBR biological treatment tank, both can be embedded in undergroundly, also can place vault.
Utility model adopts unique oil removal every slag bath, can effectively block except that foreign material, oil slick and sediment, can store and digest excess sludge again.Select aerator under water for use, can realize aerobic nitrification by aeration, can serve as stirrer again and realize the anoxic denitrification denitrogenation, without machine room, sound pollution useless is arranged at equalizing tank with inlet mouth, and it is excessive also can to reduce stink.Adopt unique water mode of straining, simple structure, stable and reliable for performance, draining is not subjected to the influence of equipment buried depth.Automatically finish biological cultivation process, can be for a long time automatically continuously or intermittent operation, running maintenance is simple.An oil removal of cleaning does not have other artificial operation items every the body refuse of slag bath about half a year.Except that electrical control cubicles, equipment places underground, can afforest or harden in ground.
Description of drawings
Describe the structure and the technical process of equipment in detail below in conjunction with accompanying drawing (equipment sectional view).Constitute housing by glass reinforced plastic or the metal sheet that scribbles impregnating material, impregnating material can adopt resin, epoxy coal asphalt paint or other analogous materials.In housing, be separated out 3 oil removals every slag bath, 1 equalizing tank and 1 SBR biological treatment tank with above-mentioned materials.
Sewage enters oil removal every slag bath (2) by water-in (1), blocks through grid (3) earlier and removes thick foreign material, and oil removal can effectively be blocked except that oil slick and sediment every slag bath (2), and stores and digest the excess sludge of SBR biological treatment tank (14) generation; Water outlet enters equalizing tank (5) through thrust-augmenting nozzle (4) gravity flow, and water inlet submersible sewage pump (8) lifting sewage enters SBR biological treatment tank (14); After SBR biological treatment tank (14) reaches high liquid level, starting under water, aerator (12) carries out aerobic aeration and anoxic stirring, inlet pipe (11) import of aerator (12) under water is located at equalizing tank (5), on inlet pipe (11) pipeline electrically operated valve (9) is housed, when electrically operated valve (9) is opened under water aerator (12) carry out aerobic aeration, electrically operated valve (9) when closing under water aerator (12) carry out anoxic and stir; Aerator (12) carries out stopping after aerobic aeration and anoxic are stirred for some time under water, and SBR biological treatment tank (14) is in the precipitation state; About about 1 hour of SBR biological treatment tank (14) precipitation, pollutants in sewage is fully degraded at SBR biological treatment tank (14), suspended substance is precipitated to be held back, start the draining submersible sewage pump (15) that is arranged on about 1 meter high support (17) at the bottom of SBR biological treatment tank (11) pond, the supernatant liquor of SBR biological treatment tank (14) is through rising pipe (18) standard discharge; After SBR biological treatment tank (14) reached low liquid level, draining submersible sewage pump (15) stopped, and started spoil disposal submersible sewage pump (10), extracted the part excess sludge out and entered oil removal every slag bath (2) storage and digestion through shore pipe (6).
Oil removal is equipped with access opening (16) every slag bath (2), equalizing tank (5) and SBR biological treatment tank (14).Water inlet submersible sewage pump (8), aerator (12), draining submersible sewage pump (15) and spoil disposal submersible sewage pump (10) are equipped with self coupling device (7) under water, are convenient to take out to keep in repair.
Equipment is arranged to automatic cycle when operation, starts or stops periodic duty by the equalizing tank liquid level, all electromechanical equipments according to the program of setting in the automatic control cabinet with limit in relevant liquid level under automatic operation.When equalizing tank reached high liquid level, cycle (phase can be made as 8 hours weekly) starting point timing began, and water inlet submersible sewage pump (8) starts, and moved 1 hour or SBR biological treatment tank (14) stops intake pump when reaching high liquid level; Timing 1 hour aerator (12) under water starts, and moves to stop after 5 hours; Timing 7 hours, draining submersible sewage pump (15) start, and moves 1 hour or SBR biological treatment tank (14) reaches when hanging down liquid level and stops; Timing 1 hour, the electrically operated valve (9) of aerator (12) inlet pipe is opened under water, closes after 4 hours; After the timing 7.9 hours, spoil disposal submersible sewage pump (10) starts, and spoil disposal stopped after 5 minutes.After the timing 8 hours, the cycle timing is made zero, and enters the next cycle of operation (cycle duration and in the cycle each time in stage can shorten or prolong according to practical situation).
The operation condition and SBR biological treatment tank (14) the periodic duty technology of each electromechanical equipment match (referring to SBR biological treatment tank Running Status Table) in cycle, and SBR biological treatment tank (14) is realized the loop cycle of water inlet, aerobic nitrification, anoxic denitrification, precipitation, drainage procedure successively.Equipment moves one or more all after dates, and the equalizing tank liquid level is reduced to low liquid level, and then equipment enters lay-up period, rises to high liquid level until the equalizing tank liquid level, and equipment is the restore cycle operation again.Between lay-up period, aerator (12) started aeration oxygen supply 1 hour every 6 hours under water, to guarantee the activity of active sludge.
