Abstract
The utility model discloses a kind of floating stuffing for sewage treatment, which is enclosed by two Loadings On Hemispherical Shells, is obtained spherical floating stuffing, is filled with soft fixed filler in spherical floating stuffing；Spherical floating stuffing surface is equipped with multiple fish ridges, is additionally provided with striated structure on spherical floating stuffing.The utility model floating stuffing surface is equipped with fish ridge, under hydraulic blow, can effectively function as " lodicule " effect, improve the structural behaviour of filler entirety, and not only the shock resistance of raising filler, makes filler uniform force, and filler be not easy to accumulate it is agglomerating；In addition, the utility model floating stuffing uses detachable splicing structure, it is easily changed, soft-filler is filled with inside filler, combined type loads the biofilm biomass that can be further improved filler；Finally, the utility model floating stuffing is in chondritic, mutual collision area is reduced while improving packing specific area, improves biofilm stability.
Description
Technical field
The utility model relates to a kind of floating stuffings for sewage treatment, belong to sewage treatment field.
Background technique
Currently, conventional suspension formula filler that there are resistances is big, be easy to conglomeration, vulnerable to waterpower flow the disadvantages of, thus sternly
Carrier surface forming biofilm property is constrained again.It is especially poor in mixing effect, under the biggish operating condition of mixed flow resistance, biomembrane and water body processed
Effective contact area will also be greatly reduced, sewage hardly results in efficient process.And on this basis, it is used in MBBR technique
Floating stuffing the shortcomings that overcoming suspension type filler, but be limited to water currents, filler is easily impacted discharge outlet, thus point
From difficulty, treatment effeciency is low.So developing a kind of floating stuffing for sewage treatment is particularly important.Chinese patent
CN201410115695.8 discloses a kind of sewage treatment filler, which is made of fixing piece, distribution support and packing element,
The design of " umbrella " type distribution supporter increases the specific surface area of filler, further increases the adhesion amount of microorganism.But it should
Filler belongs to soft fixed filler, is easy accumulation conglomeration, is unfavorable for later period biofilm.Chinese patent CN201510535104.7 is disclosed
A kind of novel domestic sewage handles filler, which is made of composite bushing, porous aggregate, careless cage filler and aeration tube.Its
The composite material of hard polyvinyl chloride and polyacrylic resin can form integrated compound surface layer on main structure surface, to reach
Rapid biofilm effect.But due to using compound pipe sleeve, the case where later period will appear blocking, biological film properties are influenced.Therefore,
For the deficiencies in the prior art, a kind of exploitation of the floating stuffing for sewage treatment is necessary.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of floating stuffing for sewage treatment, which is filled out
Material uses chondritic, and multiple fish ridges are arranged in chondritic surface, it is made to improve packing specific area and shock resistance
Mutual collision area is also reduced while performance, to improve the biofilm stability of filler.
In order to solve the above technical problems, technical solution used by the utility model is as follows:
A kind of floating stuffing for sewage treatment, the floating stuffing are enclosed by two Loadings On Hemispherical Shells, obtain ball
Shape floating stuffing, spherical floating stuffing is interior to be filled with soft fixed filler；It is carinate convex that spherical floating stuffing surface is equipped with multiple fishes
It rises, fish ridge is linearly arranged；Multiple striated structures are also distributed on spherical floating stuffing, striated structure is evenly distributed on
Filler surface.
Further preferably, the fish ridge is polypropylene fish ridge.
Further preferably, filler surface is evenly distributed with the fish ridge of 8 linear shape arrangements.
Further preferably, two Loadings On Hemispherical Shells are connected with each other by hasp and holding groove.
Compared with prior art, technical solutions of the utility model have the beneficial effect that
The utility model floating stuffing surface is equipped with fish ridge structure, under hydraulic blow, can effectively function as " lodicule " work
With the structural behaviour of improvement filler entirety not only improves the shock resistance of filler, makes filler uniform force, and filler is not
It easily accumulates agglomerating；In addition, the utility model floating stuffing uses detachable splicing structure, it is easily changed, filling inside filler
There is soft-filler, combined type loads the biofilm biomass that can be further improved filler；Finally, the utility model floating stuffing is in ball
Shape structure reduces mutual collision area while improving packing specific area, improves biofilm stability.
Detailed description of the invention
Fig. 1 is the top view of the utility model floating stuffing；
Fig. 2 is the overlap joint schematic diagram of two Loadings On Hemispherical Shells；
Fig. 3 is the structural schematic diagram of soft fixed filler in Loadings On Hemispherical Shell.
Specific embodiment
Technical solutions of the utility model are further described with reference to the accompanying drawing.
As shown in Figures 1 to 3, the utility model is used for the floating stuffing of sewage treatment, and the floating stuffing 7 is by two hemispherical Shells
Body 5 encloses, and obtains spherical floating stuffing, and two Loadings On Hemispherical Shells 5 pass through hasp 2 and the mutually overlap joint company of fixation of holding groove 3
It connects, hasp 2 is embedded in holding groove 3, and mutual cooperation is fixedly connected, and it is built-in that this detachable connection type is conveniently replaceable shell
The soft-filler 6 filled out, spherical floating stuffing is interior to be filled with soft fixed filler 6, and soft fixed filler 6 is acrylic fibers material；It is spherical
Floating stuffing surface is equipped with multiple fish ridges 4, and fish ridge 4 is evenly distributed on whole filler surface, fish ridge 4
Linear arrangement, fish ridge 4 are polypropylene fish ridge, and fish ridge 4 can be used for optimizing filler in sewage
Hydraulics avoid filler accumulation agglomerating；It is additionally provided with striated structure 1 on spherical floating stuffing 7, striated structure 1 can allow microorganism
It is substantially adhered on internal soft-filler 6 by gap between striped.
Loadings On Hemispherical Shell 5 is that corrosion-resistant hydrophilic material polypropylene is prepared, and is loaded inside spherical floating stuffing 7 soft
Filler 6, combined type filling can be further improved filler entirety biofilm biomass；Spherical 7 surface of floating stuffing is equipped with fish ridge structure
4, fish ridge structure 4 makes floating stuffing have very strong hydrodynamics characteristic in water, and external force resistance impact strength is high；Function simultaneously
Property water wetted material enables the higher micropopulation of floating stuffing surface deposition activity, and biofilm effect is good, anti-shock loading energy
Power is strong, is not easy to plug.
The utility model floating stuffing is applied in sewage treatment, the removal rate of the COD and BOD of sewage are stablized 70%
Between~85%, filler service life is long, and replacement is easy, and reuse rate is high.
