Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, not do under the situation of opposite explanation, the noun of locality of use is normally indicated the direction shown in the Figure of description like " upper and lower, left and right ".
The utility model provides a kind of biofilm carrier; Wherein, This biofilm carrier comprises being the four-prism face 1 of a for H, the bottom surface length of side highly; The a plurality of difference of this four-prism face 1 set inside along its length with the corrugated division plate of width, two sides of each said division plate are connected with two relative opposite side respectively.
The inside of the four-prism face 1 of the biofilm carrier of the utility model is divided into the space of a plurality of spaces through corrugated division plate; This division plate is distinguished along its length and width; And two sides of division plate connect respectively at two relative opposite side, that is to say that the length of division plate equals the foursquare length of side.Because there is the space of a plurality of such separations in carrier inside, makes biofilm carrier have good voidage, help gas and water passes through.
Need to prove that this division plate is a waviness, so not only increased the specific surface area of biofilm carrier, strengthened load quantity of microorganism, help improving biochemical reaction rate.
In addition, four seamed edges of four-prism face 1 can adopt fillet, and are as depicted in figs. 1 and 2, avoided biofilm carrier to have sharp corner like this, help the impact of buffer fluid.
Through technique scheme, the biofilm carrier of the utility model comprises the four-prism face and is arranged on this cylinder inner and be the spatial division plate at a plurality of intervals with the cylinder internal separation.Through said structure, make this biofilm carrier have ideal voidage, venting capability and mistake water-based ability, and increased the specific surface area of this biofilm carrier, strengthened the load of microorganisms amount of unit volume carrier, improved the volumetric loading of biological reaction tank.
Preferably, said first division plate 21 and second division plate 22 of broad ways along its length is provided with respectively equally spacedly.
Because in the utility model, the length direction and the width of four-prism face 1 are respectively arranged with division plate, therefore preferably, second division plate 22 of first division plate 21 along its length and broad ways is provided with respectively equally spacedly.Like this, all equate in the four-prism face 1 inner a plurality of spaces that form, thereby make that the fluid that passes through biofilm carrier is more even, help the speed of biomembranous growth and biochemical reaction.
Preferably, said first division plate 21 equates with the quantity of said second division plate 22.
Through first division plate 21 and second division plate 22 that equal amount is set in the four-prism face 1 of biofilm carrier, make to be divided into a plurality of square cylinder space in the four-prism face 1.
Preferably, the surface of said square cylinder 1 and/or said division plate is smooth or has projection.
In the utility model, the surface of said square cylinder 1 and/or said division plate can be for smooth or have a projection.And projection also can adopt various ways, for example saw-toothed projections, circular arc projection or corrugated protrusions etc.In addition, square cylinder 1 can have the different surface characteristic with division plate, and in preferred implementation as shown in Figure 2, square cylinder 1 all adopts the surface with projection with said division plate.
Such format surface can suitably increase the specific surface area of biofilm carrier as required.And also can play good shock absorption, thereby make the microbial film on biofilm carrier surface be difficult for running off for impact force of water flow.
Preferably, the thickness of said tetragon cylinder 1 and said division plate is 0.05mm-3mm, and the height of said tetragon cylinder 1 and bottom surface length of side ratio H/a are 0.2-1.5.Preferably, said first division plate (21) and said second division plate (22) are 1-10.
More than the given an example size and the structural parameter of preferred implementation of biofilm carrier of the utility model are preferably selected the manufacturing dimension of biofilm carrier in above-mentioned scope, can obtain wastewater treatment efficiency preferably.But the utility model is not limited to this, can make according to actual needs.
Preferably, the proportion of said biofilm carrier is 0.90-0.99.Because the biofilm carrier of the utility model need be suspended in the water usually, the material of therefore selecting proportion to be slightly less than water is made, thereby makes this biofilm carrier to be suspended in the sewage preferably.Usually, the biofilm carrier of the utility model is selected organic polymer material, generally adopts materials such as Vilaterm or Vestolen PP 7052.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
