The present invention combines the nonwoven fabric used for wastewater treatment with a rotating disk, and by rotating the disc nonwoven fabric, the microorganisms activated in the nonwoven fabric are repeatedly contacted between the wastewater and the air. It relates to a combined rotating disk.

Until now, there have been methods of combining nonwoven fabrics at regular intervals and treating them by completely immersing them in the waste water and rotating them with foamed foam foam discs. However, in the former case, the microorganisms are completely immersed in the waste water for a long time. A separate device for oxygen supply was needed. In the latter case, the foam space of the foam plate was small, so it could not be filled with many microorganisms. Therefore, the foam plate had to be largely formed. .

In the present invention, the above-mentioned defects are corrected, and the nonwoven fabric of Invention Patent Application No. 85-479, which is selected by the applicant, is easily formed to a suitable size, and is coupled to the circular structure by a circular body, but the connecting rod is connected to the element element by the wedge. The nonwoven fabric can be easily and firmly coupled to a plurality of support plates that are fully coupled.

The connecting rod 6 is inserted into the insertion hole 5 which is perforated in the element element in a known circular support consisting of a radial bar 3 and a transverse bar 4 connecting the central bar 2 to the mandrel installed on the drive shaft 1. The connecting rod is attached to a central shaft insertion pipe 11 having a nonwoven fabric thickness having a concave end portion 11 'into which the shaft insertion pipe 21 of the other supporting plate 20 is to be inserted at the inner diameter front end. One side support plate 10 having a branch connecting rod 12 attached to the outer wall to which the wedge insertion hole 15 is recessed and the tip outward protrusion 13 can be dislocated inwardly. Insertion pipe 21 having a half length of both support plate spacing to the outer diameter to be inserted into the mouth is attached to the center of both sides, and the other side support plate (20) perforated with the insertion hole 22 of the outer diameter to correspond to the branch connecting rod to the outside of the plate Sandwich the nonwoven fabric with) Penetrate the outward projection in the insertion hole of the other support plate by reducing the outward projection through the insertion hole and the locking ring 23 so that the outward projection is caught by the locking ring, and then presses into the wedge insertion hole as wedges 24 to make the The outward projections are fixed so that the nonwoven fabric is coupled to the entire circular support in such a way that the unexplained reference numeral 7 is a support piece to which power is transmitted as the key 8.

The present invention having the structure as described above includes one side support plate of the support plate for each part of the nonwoven fabric by punching through-holes in accordance with the connecting rods 6 and the branch connecting rods 12 to the nonwoven fabric partially woven to fit the circular body of the power panel. Inserted into the connecting rod (6) and the branch connecting rod (12) of the other side and the other support 20 is inserted into the connecting rod to be adjacent to each other after compressing the tip outward projection (13) of the branch connecting rod (22) the engaging ring (23) Reduction of the outward protrusion 13, which has been compressed by inserting in the c), is coupled to the outward protrusion by the engaging ring, and then the wedge 24 is inserted into the wedge insertion hole 15 concave in the center of the outward protrusion so that the outward protrusion is inward. It is possible to fix the sculpted nonwoven fabric easily and firmly with a partial support plate to the element elements of the circular body support by fixing it completely so as not to shrink. Because no tongue lot of space in the non-woven fabric can be filled with a lot of micro-organisms and which will by the contact of the air with a certain constant rotation of the rotary disc to facilitate the supply of oxygen.

Claims (1)

The connecting rod 6 is inserted into the insertion hole 5 which is perforated in the element element in a known circular support consisting of a radial bar 3 and a transverse bar 4 connecting the central bar 2 to the mandrel installed on the drive shaft 1. The connecting rod is attached with a central shaft insertion pipe 11 having a nonwoven fabric thickness length having a concave end 11 'into which the shaft insertion pipe 21 of the other supporting plate 20 is inserted. One side support plate 10 and a support plate 10 having branch connecting rods 12 cut out of several incisions 14 on the outer wall so that the wedge insertion hole 15 may be recessed and the tip outward protrusion 13 may be coalesced inwardly. Insertion pipe 21 having a half length of the gap between the two support plates in the outer diameter to be inserted into the mouth is attached to the center of both sides, and the other side support plate (20) perforated with the insertion hole 22 of the outer diameter to correspond to the branch connecting rod to the outside of the plate The nonwoven fabric is clamped with a wedge insertion hole (15) to wedge (24). Rotating disk combined with a waste cloth for sewage treatment.
