The present invention relates to a biofilm carrier filled in a microbial reaction tank for treating sewage and wastewater or a microbial culture tank for producing pharmaceuticals and food.

Biofilm carriers are made in a shape that increases the specific surface area in order to increase the adhesion of microorganisms. In general, it is made of various materials and forms such as ciliated or loofah using synthetic resin, foam such as polyurethane or foamed sponge using waste tire, and plate-like carrier fixed with thick cloth using synthetic fibers. Ciliary or scrubber-type carriers have high adhesion of microorganisms but are not easily detachable, which causes anaerobic internalization, and complementary sponge-type carriers are small in size and excellent in many aspects such as fluidity and desorption ability of microorganisms. However, the wear resistance is weak and has a short lifespan. In addition, in the case of the plate-type fixed to the reaction tank or the culture tank there was a problem that the surface resistance due to the inhibition of the flow and agitation of the weight and fluid by the growth of the attached microorganisms.

Accordingly, the present invention provides a floating semi-fixed microorganism carrier unit having a large specific surface area of a carrier, high durability, excellent desorption ability of microorganisms, and not interfering with the flow and mixing of the fluid in the tank, and easy to install and maintain. There is a purpose.

In order to achieve the above object, the microorganism attachment carrier unit according to the present invention is a microorganism carrier unit for attaching and growing microorganisms, the microorganism attachment group including a plurality of microorganism attachment materials in the form of a membrane to which microorganisms are attached and the microorganism attachment It includes a sealed air bag connected to the ash group to float the group of microbial adhesives on the surface, wherein the microbial adhesive group is arranged in a form in which a plurality of microbial adhesives are stacked on each other with a predetermined interval between the adhesives Arranged and fixed in a row, the carrier unit includes a plurality of microbial attachment groups, wherein the plurality of microbial attachment groups are connected to each other in a row and fixed, and the air bag is selected from the plurality of biological attachment groups. Characterized in that it is connected to only one of the groups of microbial attachments located at both ends All.

In the above-mentioned carrier unit for microorganism attachment according to the present invention, the microorganism attachment material is a nonwoven fabric.

Hereinafter, the present invention will be described in more detail.

The carrier material used in the present invention is a woven or non-woven fabric made of synthetic fibers, and any material can be used if it is advantageous for adhesion growth of microorganisms such as ciliated protruding ciliary layer on the surface, sponge form of polyurethane material or porous ceramic. It is irrelevant. However, a thin film-shaped nonwoven fabric having excellent strength and abrasion resistance, non-toxicity, high permeability, light weight, and high microbial adhesion is most preferred. A group of microbial attachment materials in which nonwoven membranes are arranged in a stacked form in order to widen the specific surface area of the nonwoven fabric, but the membranes are arranged in a line so as to be spaced apart from each other with a predetermined space therebetween so that biofilms formed between the nonwoven fabrics are not anaeroded. Configure 40.

Connecting a plurality of microbial attachment groups 40 as described above, but connected vertically with a flexible ring (7), and only one of the microbial attachment groups located at both ends of the plurality of microbial attachment groups are connected. By connecting the sealed air bag 5 of plastic material, the group of microbial attachment materials connected to the air bag 5 is floated on the surface of the water, and the remaining group of microbial attachment materials is submerged in water. The microorganism attachment carrier units 50 configured as described above are filled in a plurality of tanks so that the positional movement between the groups of microorganism attachment materials can be flowed left and right only by the flow of the fluid, so that smooth agitation and local stagnation of the fluid are achieved. To facilitate the desorption of microorganisms. Carrier unit according to the present invention is configured by connecting vertically by using a flexible material connecting ring to adjust the height by separating or combining the group of microorganism attachment material according to the size and depth of the tank from the water surface.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. However, the scope of the present invention is not limited thereto.

1 is an exploded assembly view of a carrier unit according to the present invention. The microorganism attachment material 1 acts as a carrier for the floating or adhesion growth of microorganisms. The microorganism attachment material 1 is a thin or rectangular film having a width and length of 8 cm to 30 cm or a rectangle and a thickness of 0.5 mm to 12 mm. The material is a woven or non-woven fabric made of synthetic fibers, and any material may be used as long as it is advantageous for the growth of microorganisms such as a ciliated layer protruding from the surface of the ciliated layer, a sponge form of polyurethane material, or a porous ceramic.

The microorganisms are attached to the surface of the microorganism attachment material 1 by dividing the multiple layers of microorganism adhesion material 1 at regular intervals but separating each microbial adhesion material 1 with a tube tube 2 so as not to overlap. When growing, it serves to prevent the microbial adherents (1) overlap with each other by the flow of fluid to anaerobic, and passing the fixed rod (3) through the microbial adherents (1) and the knot tube (2) Fixed to the porous fixing plate 4 is configured to play a role of preventing the microbial adhesion material 1 from twisting. The microorganism attachment group 40 composed of the microorganism attachment material 1, the node tube 2, the fixing rod 3, and the fixing plate 4 is empty to allow the microbial reaction tank and the culture tank to float on the surface of the microbial reaction tank and the culture tank. Using a sealed air bag (5) of plastic material, and using a fixing band (6) to fix the air bag (5) to the porous fixing plate (4), according to the depth of the tank microorganism attachment group (40) A connecting ring 7 is attached to the fixing plate 4 to separate or connect the whole carrier unit 50.

FIG. 2 is a perspective view showing a carrier unit 50 to which the microbial attachment group 40 of FIG. 1 is connected in plural. FIG. 2 is a microbial attachment group 10 and a microbial attachment group submerged in water. 20) and the connection state 30 of the group of microorganism attachment materials. Each group of microbial attachment materials 20 is positioned vertically downward by the weight of the microorganisms in the water.

FIG. 3 is a schematic view showing an embodiment of a tank in which the carrier unit 50 of FIG. 2 is installed. The unit 50 may be formed by adding or removing a group of microorganism attachment materials 40 according to the depth of the tank. The height of the can be adjusted, and fills 20% to 50% of the volume or length of the tank from the surface of the water does not sink to the bottom of the tank, if filled in the aeration tank, bubbles generated through the diffuser 100, and anaerobic tank if installed in the stirring device Since the carrier unit 50 flows in the left and right directions by the 200, smooth agitation is achieved and no local congestion occurs.

Floating semi-fixed biofilm carrier unit of the present invention is excellent in the desorption of microorganisms because it flows according to the flow of the fluid in the tank, and the specific surface area is wide by fixing the microbial contact materials do not overlap multiple layers, the adhesion of microorganisms It can maintain high concentration of microorganisms, so it can be used in microbial reaction tanks of sewage and wastewater treatment facilities or industrial wastewater treatment facilities where the impact of microorganisms from load fluctuations is severe. Can be used.

In addition, this unit is floating type, so it is easy to install and manage, adjust the length of the unit according to the height of the tank, prevent local congestion when stirring, and durability and easy removal of microorganisms. Then there is an effect that can reduce the cost of the carrier.
