Abstract

The utility model relates to a three-dimensional combined type biofilm carrier. The three-dimensional combined type biofilm carrier comprises a hollow sphere, a floating frame, hook rails and film bags, wherein the hollow sphere is fixedly connected above the floating frame, the hook rails are connected below the floating frame, the film bags are hooked on each hook rail at equal intervals, and the film bags in one shape are hooked on one hook rail; the floating frame can be formed by rolling by adopting a light material or adopts an independent plate distributed with holes; each film bag can be a reticular body or be made by wrapping a flexible material at the periphery of one support; the three-dimensional combined type biofilm carrier is arranged in waste water, the whole three-dimensional combined type biofilm carrier is suspended in water by virtue of the floating frame, most of the hollow sphere is in water, the floating frame is also in water under the action of the gravity of the hook rails, and the hook rails and the film bags on the hook rails are in deep water; the three-dimensional combined type biofilm carrier is high in capacity, biofims can be formed on the hollow sphere, the floating frame, the hook rails and the film bags respectively, the quantity of the biofilms is high, biofilm culturing distribution is wide and uniform, and the three-dimensional combined type biofilm carrier is easy to replace.

Description

A kind of stereo assembled biofilm carrier

Technical field

The utility model relates to a kind of by the biomembrance process biomembranous carrier of growing in process of disposing of sewage, and belongs to biofilm carrier technical field.

Background technology

Biofilm carrier in biomembrance process wastewater treatment process for microorganism provides the stable environment of perching and breeding.The main biofilm carrier adopting has plastics or frp honeycomb shape, spherical or three-dimensional wavy carrier etc., and these carrier surfaces are smooth, and microbial film adheres to rate variance, easily aging, and often easily produces and stop up in actual use.Also have the carrier that adopts soft fiber or half soft fiber, these carriers are undesirable at flow-shape, easily tied together by microbial film cat, produce balling phenomenon, its effective surface area is greatly reduced, and then produce anaerobism phenomenon in the inside of balling, affect treatment effect.Existing biofilm carrier structure and shape are all more single, and the scale of construction is little, and biofilm amount is few, and need a large amount of uses or string to hang over together and use, complex operation, replacing is wasted time and energy.

Also occurred at present the spherical suspending carrier being made up of inside and outside double-deck spheroid, claimed again porous rotary spherical suspending carrier, outside is hollow fish netted spheroid, and inside is spinning ball.But this carrier can only be suspended in water surface, can not form microbial film in the depths of water body.Because filling ball spherome surface is smooth, centre of sphere segment space is little, is unfavorable for biomembranous formation, has limited the diffusion of water pollutant to spheroid inside, affects water treatment effect simultaneously.

Summary of the invention

The scale of construction that the utility model exists for biofilm carrier in existing sewage disposal is less than normal, biofilm is single and change the deficiencies such as loaded down with trivial details, and to provide that a kind of scale of construction is large, biofilm distributes wide, change easy stereo assembled biofilm carrier.

Stereo assembled biofilm carrier of the present utility model, by the following technical solutions:

This biofilm carrier, comprises hollow out ball, scaffold, peg and film bag, hollow out ball be fixedly connected on scaffold above, be connected with peg below scaffold, on every peg, all compartment of terrain hangs with film bag, has a kind of film bag of shape on a peg.

Scaffold can adopt light material rolling, or adopts the pertusate only plate that distributes.

Film bag can be reticulate body or make at the periphery of support parcel flexible materials.Film bag shape on every peg is all different.

Above-mentioned biofilm carrier is placed in waste water, by scaffold, whole carrier is suspended in water body, hollow out ball major part in water, under the gravity of peg scaffold also in water, peg and on film bag in water body depths, formed the biofilm carrier of the large scale of construction.

The utility model has formed the biofilm carrier of upper, middle and lower solid by hollow out ball, scaffold and peg, increased the scale of construction of biofilm carrier, all can form microbial film on hollow out ball, scaffold, peg and film bag, biofilm biomass is large, biofilm distributes wide, and is evenly distributed, and to change convenient simultaneously.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, hollow out ball, 2, scaffold, 3, peg, 4. film bag.

Embodiment

The structure of stereo assembled biofilm carrier of the present utility model as shown in Figure 1, comprise hollow out ball 1, scaffold 2, peg 3 and film bag 4, hollow out ball 1 be fixedly connected on scaffold 2 above, below scaffold 2, be connected with peg 3, peg 3 is uniform below scaffold 2, and on each peg 3, all compartment of terrain hangs with film bag 4.By scaffold 2, whole carrier is suspended in water body.Scaffold 2 can adopt light material (as bamboo pole, tree branches or plastics tubing etc.) rolling, if adopt an only plate, hole will distribute on it.Film bag 4 can be the reticulate body of plastics, or wraps up or be wound around the flexible materialss such as nylon, bolting silk, terylene, non-woven fabrics, 3 D filter cloth in the periphery of a support and make.On every peg 3, have a kind of film bag 4 of shape, namely the shape of the film bag 4 on every peg 3 is all different, and film bag shape on same peg 3 is identical, and distribution can make microbial film be more evenly distributed like this.The shape of film bag 4 can be the different shapes such as trilateral, spherical, cylindrical, oval, hexagon, rhombus or Pear-Shaped.

Above-mentioned biofilm carrier has formed the biofilm carrier of upper, middle and lower solid by hollow out ball 1, scaffold 2 and peg 3, be placed in waste water, due to the effect of scaffold 2, entirety is bubbled through the water column, hollow out ball 1 major part is in water, under the gravity of peg 3, scaffold 2 is also in water, peg 3 and on film bag 4 in water body depths.Like this, the scale of construction of whole biofilm carrier is large, all can form microbial film on hollow out ball 1, scaffold 2, peg 3 and film bag 4, and biofilm biomass is large, and biofilm distributes wide, and is evenly distributed, and is convenient to change simultaneously.

Claims

1. a stereo assembled biofilm carrier, it is characterized in that: comprise hollow out ball, scaffold, peg and film bag, hollow out ball be fixedly connected on scaffold above, be connected with peg below scaffold, on every peg, all compartment of terrain hangs with film bag, has a kind of film bag of shape on a peg.

2. stereo assembled biofilm carrier according to claim 1, is characterized in that: described film bag is reticulate body or makes at the periphery of support parcel flexible materials.
