Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of high-performance bio fluidized-bed, comprise outer case, dividing plate, flow deflector and the screen plate 15 with filter opening are installed in outer case.Outer case inside is separated into oxygen-starved area 1, single filter district 2, aerobic zone 3, cascade filtration district 4 and settling region 5 by dividing plate, flow deflector and screen plate 15 successively.Outer case can be cuboid, and outer case can have the outer shrouding matching piece steel stiffening web of polylith to be spliced.Outer case is provided with wastewater inlet and treated water outlet.
Oxygen-starved area 1 is enclosed by the inwall of outer case and a dividing plate 81 and forms, and dividing plate 81 can be a rectangular plate, and four corners connect respectively at outer case inside, to reach object outer case interior separation being become several region.
Be provided with filler unit 6 and water distributor 7 in oxygen-starved area 1, the lower end of filler unit 6 communicates with the outlet of water distributor 7, and upper end communicates with single filter district 2.The hypoxia device of oxygen-starved area 1 is filler and stuffing frame composition, and filler can be semi soft packing.
One end of water distributor 7 is connected with wastewater inlet, the other end runs through the lower end that filler unit 6 stretches into filler unit 6, make sewage first after the lower end of filler unit 6 is by filler unit 6, from the upper end of filler unit 6, namely the upper end of outer case enters single filter district 2.Can be communicated with single filter district 2 by pipeline in the cavity of filler unit 6 upper end, also can by a passage be offered by the dividing plate 81 between single filter district 2.
In oxygen-starved area 1, need sewage to be processed first this water distributor 7 sends into the bottom of outer case, then after by the filler unit 6 in the middle part of outer case, enters single filter district 2 above outer case.The mode of this backflow, layout structure seems compacter.
Single filter district 2 and oxygen-starved area 1 are separated by dividing plate 81, are provided with flow deflector 91 between single filter district 2 and aerobic zone 3, and flow deflector 91 is provided with circulation road 10.Namely the region that dividing plate 81 and flow deflector 91 surround defines single filter district 2.Be provided with first level filtering device 11 in single filter district 2, the filtering outlet of first level filtering device 11 communicates with circulation road 10.First level filtering device 11 comprises screen plate 15, and screen plate 15 is fixed between dividing plate 81 and flow deflector 91, and screen plate 15 is placed with filtering material, and screen plate 15 is played a supporting role, and filtering material can be the primary filter materials such as pebbles.
The sewage entered from oxygen-starved area 1 is above outer case, and therefore first level filtering device 11 also can be arranged on outer case inner upper position, and the filtering surface of first level filtering device 11 is directly communicated with the outlet of oxygen-starved area 1.Water body after filtering enters aerobic zone 3 from the circulation road 10 below screen plate 15.
Install the flow deflector 92 with circulation road 10 between aerobic zone 3 and cascade filtration district 4, aerobic zone 3 is enclosed by flow deflector 91 and flow deflector 92 and forms.The bottom of aerobic zone 3 is provided with aerating apparatus; Be provided with filler above aerating apparatus, filler can be suspension ball filler, can as the carrier of active bio mud.Aerating apparatus is made up of aeration tube 12 and aeration tube support 13, and aeration tube support 13 is arranged on bottom outer case, and aeration tube 12 is provided with pore, is arranged on aeration tube support 13.Aeration tube 12, for providing sufficient oxygen in aerobic zone 3, makes active bio mud can purify sewage.
Be provided with dividing plate 82 between cascade filtration district 4 and settling region 5, cascade filtration district 4 is enclosed by dividing plate 82 and flow deflector 92 and forms.Be provided with two-stage filter 14 in cascade filtration district 4, two-stage filter 14 can be identical with first level filtering device 11.The purge outlet of two-stage filter 14 communicates with the settler entrance of settling region 5.The process water flowed out from aerobic zone 3 enters below the screen plate 15 of two-stage filter 14, from lower to upper after filtering material, then enter settling region 5.
The settler outlet of settling region 5 communicates with the water port of outer case.Settler comprises connecting tube 16, perpendicular stream cylinder 17 and filling body 18, and connecting tube 16 is arranged on the top of settling region 5, connects the purge outlet of two-stage filter 14 and the upper port of perpendicular stream cylinder 17.Perpendicular stream cylinder 17 runs through filling body 18 and stretches into outer case lower end and communicate with the water-in of filling body 18, and the water outlet of filling body 18 communicates with water port.The filler that filling body 18 comprises filler support 20 and is arranged on filler support 20; Filler is suspension ball filler.Enter the process water of settling region 5 first above filling body 18, flow into below settling region 5 through perpendicular stream cylinder 17, flow out from the low side of perpendicular stream cylinder 17, be provided with two pieces of swash plates 19 below the bottom end outlet of perpendicular stream cylinder 17, swash plate 19 can be conducive to mud and form backflow in bottom.Process water from bottom to top through filling body 18, outer case is discharged in draining face then above filling body 18, completes scavenging process.
This biological fluidized bed is by suspension of biofilm in water, and microbial film is attached on filler, under aeration bubbles and waterpower promote, upper and lower loopy moving in water, microbial film on carrier fully contacts with oxygen with waste water, quick adsorption organism in water body of degrading, thus waste water is purified.Internal recycle biological moving bed improves the shortcomings of static bed biomembrane method and the deficiency of BMBR, increase filler useful area, in use have without blocking, water distribution even etc. a little.This fluidized-bed, compared with activated sludge process and BMBR, has the advantages such as efficient, compact, easy operation, excess sludge production be low, makes outlet effect more desirable.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
