Specific implementation mode
The present invention will be further described by 1-12 below in conjunction with the accompanying drawings：
A kind of MBBR sewage-treatment plants of bionical helical structure include the runner 1 of several adjoinings, the adjacent runner 1
Between connected by transition connection portion with smooth surface, biomembrane is attached to the inner surface and the outer surface of runner 1, described
The inner surface and the outer surface is streamlined smooth surface, the runner 1 in the direction of extension in the shape of a spiral, the stream of several adjoinings
The section in road 1 is symmetrical petal-shaped.When the quantity of runner 1 is 4 or 6 or 8, symmetric graph centered on the petal-shaped
Shape.When the quantity of runner 1 is 5, the petal-shaped is zhou duicheng tuxing.Adjacent 1 spacing of the runner is equal, the spacing
It is divided into 5mm or 7.5mm or 10mm three grades.1 thickness of the runner is 0.35 ± 0.1mm.The spiral helicine screw pitch range
In 40-200mm.
The application has used for reference the structure type of the marine organisms such as coral in the design process, has the characteristics that：
1, cleanliness structure realizes lower resistance to mass tranfer more suitable for treatment fluid
Form is squeezed out relative to traditional straight type, this smooth surface structure itself is more in line with hydromechanical requirement, suitable
Smooth runner design is more smooth and uniform when fluid (water body) and device being made to interact.Avoid traditional MBBR apparatus structures
The closing and barrier effect that upper straight type angle is brought, allow flow uniformly smoothly to flow through apparatus surface, are improving average dress
While surface velocity (the average shear force effect for increasing apparatus surface) set, apparatus surface stops the appropriateness of fluid
Also avoid destruction of the excessive shearing force for biomembrane.
Open outer surface inherently has more excellent mass-transfer performance, in addition rational streamlined smooth surface stream
Road designs, and has rapid raising in terms of the mutual mass transfer with water body compared with traditional form MBBR devices.
The inner surface of screw type MBBR double motor equipments equally has excellent mass-transfer performance, simultaneously because using appropriate
Closure designs, make its microorganism impacted, the unfavorable conditions such as toxicity under the influence of can have and preferably ensure survival rate, formed
Faster recovery capability；In addition, anaerobic environment appropriate can enhance the ability of simultaneous denitrification.
2, rational specific surface area design and runner are reserved
Screw type MBBR double motor equipments have fully considered biomembrane metabolism, newer needs in design, by repeatedly
Experiment determines rational spacing principle, can both ensure maximum effective ratio area, while can also meet biomembrane generation
The minimum flow path demand thanked and fallen off, has reached the harmony of biomembrane quantity and efficiency.
3, effect of mass transmitting is double dynamical
1), the automatic homogenizing of shearing force distribution
During bionical screw type MBBR double motor equipments fluidize movement in water, by its curved-surface structure to flow and air-flow
Cutting shunting function convert it into for whole device surface is orderly, uniform shearing force and during realization by
In appropriate barrier effect it is possible to prevente effectively from the excessive situation of local shear forces occurs.The bionical spiral compared with traditional MBBR devices
The resistance coefficient of type MBBR double motor equipments itself wants smaller, and this flow field uniformly acts in addition, makes its under equal conditions table
Face mean flow rate is higher than traditional MBBR devices, realizes higher mass transfer power.
2), spin motion
Bionical screw type MBBR double motor equipments can allow device in fluid interaction similar to the structure design of propeller
When generate regular spin motion, this spin motion causes the flow shear action on simultaneously even distribution device surface once more, equally
Section 2 power can be provided with the water body regeneration function on promote device surface, the effect of mass transmitting between biomembrane and water body.
4, more stable microbe survival environment
Research shows that certain hydraulic shear effect, is the important external condition of device biofilm and microbe to screen, so
Screw type MBBR double motor equipments are to the homogenization of surface shear forces to the rapid biofilm at its initial stage and the microorganism of runtime
Domestication and screening are all highly beneficial, surface biological film completely unordered hydraulic shear ring when being fluidized relative to traditional MBBR devices
For border, screw type MBBR double motor equipments can give the hydraulic shear of the biomembrane one of its surface attachment uniformly, stable
Environment will have preferably processing activity in the biomembrane that this stabilization is tamed and filtered out under orderly environment.
5, the reduction of use cost
First in terms of effective ratio area, the design of device form technically greatly reduces invalid specific surface area
It generates so that the utilization rate higher of specific surface area, to save due to consumption of raw materials caused by invalid specific surface area；Second,
In the scientific and reasonable width of flow path design of configuration aspects, is realizing reasonable specific surface area maximumlly while avoiding traditional MBBR
Device is in order to pursue merely the raw material of specific surface area and effective consumption.So screw type MBBR double motor equipments utilize effect in raw material
Considerably beyond the MBBR devices of traditional form in terms of rate, to effectively reduce cost of material.
In terms of specific surface area, traditional MBBRT devices specific surface area of runner spacing 3-5mm is 500 ㎡/m3Left and right,
Middle effective ratio area is 370 ㎡/m3Left and right；Per m3Weight 100kg or so, it is double acting according to same runner spacing screw type MBBR
The design of power apparatus, specific surface area are 450 ㎡/m3400 ㎡ of effective ratio area/m3, per m3Weight 90kg is (according to equal unit
Specific surface area consumes the calculating principle of equivalent material) left and right, it is traditional at last by volume to reach equally effective specific surface area dosage
The 92.5% of device is calculated by weight and only needs the 83.25% of conventional apparatus, and saving rate is up to 16.75%, and screw type fills in addition
The rapid promotion in terms of mass-transfer performance is set, synthesis use cost conservative estimation can reduce by 20% or more.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications, these improvements and modifications can also be made
Also it should be regarded as protection scope of the present invention.
