The present invention relates to a microorganism contact material and its treatment structure of the sewage treatment apparatus, and more particularly, to attach the microorganism to the surface in order to be oxidatively decomposed by the activity of the microorganism in the sewage flowing into the sewage treatment apparatus of the purification facility. It relates to a microbial contact material and its installation structure of the sewage treatment apparatus to purify the sewage more effectively by forming a microbial membrane to form a microbial membrane to repeatedly contact the organic material.

In general, the contact oxidation treatment method, which is one of the sewage treatment methods, fills a contact material such as a fibrous structure or a coiled structure or a simple curved plate contacted in an aeration tank to induce adhesion of microorganisms to the contact material surface. By repeatedly contacting the organic material in the influent with the oxide film formed on the ash surface, the microorganism oxidizes and decomposes the organic material to purify the sewage.

However, the contact area inducing the attachment of microorganisms thus occupies a large proportion of the sewage purification ability. Such contact materials must have a large surface area per unit volume in terms of contact efficiency of drainage, and a large porosity in order for the drainage to flow well. In addition, it should be easy to attach microorganisms, and it should be shaped so that closure does not occur by attachment sludge, and satisfy the condition that resistance should be small by load and swirl flow.

However, although many types of contact materials are currently being developed and sold, there are problems in that it is difficult to satisfy the above conditions.

In addition, in the construction for filling the contact member of the simple flat plate into the aeration tank, conventionally attaches and connects the contact material by using a special adhesive material, and as such an installation structure for fixing the attached contact material by using an external frame such as an angle and a channel. do.

However, there is a cost burden because expensive adhesives are used, and importantly, since the installed contact materials are submerged for a long time, the adhesive materials easily decay, and the connection parts of the contact materials fall, so repair or replacement is required. There is a lot of trouble.

Therefore, the present invention has been devised to solve the above-mentioned closed end, and satisfies the condition of the contact material by arranging the particle diameter or spacing of the contact material in the same manner, and connects and fixes the contact material using a sus bar. The purpose is to reduce the time and cost of installation and installation time, and to maintain robustness at all times.

The present invention for achieving the above object is filled in the aeration tank of the sewage treatment apparatus to induce the attachment of microorganisms to form a microbial membrane to repeatedly contact the organics to oxidatively decompose the organics by the activity of the microorganisms, A cup-shaped protrusion formed to be submerged, a cap-shaped protrusion formed on the upper surface opposite thereto, and a plurality of T-shaped grooves having a plurality of contact members formed at regular intervals on a plate-shaped body are laminated to form holes between the stacked areas. Inserting a suss bar and fixedly contact the contact material, it is an installation structure for coupling both ends of the sus bar with the outer frame.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment of the present invention as follows.

1 is a view of a contact member according to the present invention (a) is a plan view, (b) is a front view, (c) is a side view.

FIG. 2 is a sectional view taken along the line A-A of FIG. 1 (a), and FIG. 3 is a sectional view showing the installation state of the present invention.

As shown in Figs. 1 to 3, the present invention has a cup-shaped protrusion 11 which is formed to be light and narrow at regular intervals, and is formed to the left and right and protrudes in a planar structure that is staggered back and forth, and transversely at a position between the cap-shaped protrusions. Thus, a smaller upper and lower cap-shaped protrusion 12 is formed in the plate-shaped main body 10, and T-shaped grooves 13 are formed at regular intervals on the upper and lower surfaces of the main body so as to have a wavy cross-sectional structure.

On the other hand, at a predetermined interval in the circumferential direction of the cup-shaped protrusion 11, the grooves 15 in the height direction are provided with protrusions 16 on the inner side thereof to form contact materials.

And the installation structure of this is as shown in Figure 3 by punching the hole 14 in the laminated structure in which the cup-like protrusions and the cap-shaped protrusions (11, 12) abut each of the plurality of contact materials described above, It is composed of a structure in which the contact materials laminated left and right or up and down are tightly fixed by coupling to an external frame such as an angle or a channel. In the figure, reference numeral 31 denotes a PVC F / B for supporting between the ends of the laminated contact materials.

Looking at the effect of the present invention as described above are as follows.

The factors governing the retention amount of the microbial membrane formed per unit volume of the contact material are expressed in specific surface area, and the porosity is used to determine the retention capacity of the microbial membrane and whether the drainage flows smoothly.

Therefore, a large value of specific surface area and porosity implies that the formation width of the microbial membrane on the contact surface increases, and as a result, the retention capacity of the microbial membrane increases, resulting in a balanced maintenance of the microbial membrane. Less water resistance is an important factor in wastewater purification.

As shown in Figs. 1 to 3, the shapes formed on the contact member are arranged at regular intervals and particle diameters, so that the specific surface area is increased and the value of the porosity is increased.

In addition, as described above, the shape and form of the contact material are arranged at regular intervals and particle diameters, so that the growth and peeling of the microbial film on the surface of the contact material are maintained in a balanced manner, thereby making the adhesion of the microorganisms by having a strength of about 60㎏ / ㎡ required for the contact material. No buckling occurs, and the distance between the contact material and the contact material is maintained at a distance of about 87 mm, thereby maintaining the speed generated in the laminated contact material at 5-6 m / min to reduce the resistance of the swirl flow. To smooth the flow of water.

In addition, as shown in FIG. 3, after the contact members are laminated and connected in the horizontal or vertical direction, the sub rods 20 are inserted through the holes 14 formed in the contact members to tightly fix the contact members, and both ends of the sub rods are fixed. While being coupled to the outer frame 30 to support the load of the contact member 10 in which the microbial film is formed.

On the other hand, the grooves and protrusions 15 and 16 of the contact member have an action of maintaining the adhesion of microorganisms and sludge oxidatively decomposed.

As described above, the present invention satisfies the conditions of the contact materials by arranging the particle diameters or intervals of the contact materials in the same manner, and saves working time because the fixed contact is made by using a sustain rod without using expensive adhesive materials when constructing the adhesive materials. Not only the work is easy, but the construction cost is saved and the robustness can be maintained for a long time.
