As an embodiment of the invention, one end of the crushing rod 31 close to the elastic three-dimensional filler 2 is uniformly provided with conical pricks 311;
when the device works, when the cleaning ring 3 moves up and down in a reciprocating manner to drive the crushing rod 31 in the cleaning ring 3 to clean the biological membrane bonded on the elastic three-dimensional filler 2, the crushing rod 31 is uniformly provided with the conical pricks 311 at one end close to the elastic three-dimensional filler 2, so that when the crushing rod 31 moves up and down in a reciprocating manner, the conical pricks 311 are continuously contacted with the biological membrane bonded on the elastic three-dimensional filler 2 and pierce and crush the biological membranes bonded with each other, thereby further improving the cleaning effect of the crushing rod 31 on the biological membrane bonded on the elastic three-dimensional filler 2, avoiding the problem that the crushing rod 31 is clamped between the elastic three-dimensional fillers 2 in the cleaning process due to the excessively tight bonding between the biological membranes, so that the cleaning ring 3 stops at a blocked position, the cleaning of the elastic three-dimensional filler 2 cannot be finished, and the sewage treatment effect in the reaction tank 1 is poor.
As an embodiment of the present invention, the crushing rod 31 is made of an elastic material;
when the device works, the cleaning ring 3 reciprocates to drive the crushing rod 31 in the cleaning ring 3 to reciprocate, so that when the crushing rod 31 is in contact with the biological films bonded with each other on the elastic three-dimensional filler 2, the biological films are divided into partial fine fragments under the action of the miniature cone pricks 311 on the crushing rod 31, then the excessively thick biological films bonded on the elastic three-dimensional filler 2 are cleaned under the driving of the reciprocating motion of the crushing rod 31, at the moment, the crushing rod 31 is directly in contact with the excessively thick biological films bonded together, and the crushing rod 31 is made of an elastic material such as a rubber material, so that the crushing rod 31 bends under the action of the external reaction and rebounds, certain vibration is generated on the excessively thick biological films bonded with each other between the elastic three-dimensional fillers 2, the excessively thick biological films bonded between the elastic three-dimensional fillers 2 are further promoted to fall off, the cleaning effect on the elastic three-dimensional fillers 2 is improved, meanwhile, when the crushing rod 31 is in contact with the elastic three-dimensional filler 2 along with the cleaning ring 3, the elastic three-dimensional filler 2 is clamped between the elastic three-dimensional filler 2, and the elastic filler 31 is further prevented from being broken when the elastic rods 31 are broken and the elastic three-dimensional filler 31 is broken materials 31, and the elastic three-dimensional filler 2 is broken when the elastic three-dimensional filler 31 is broken when the elastic three-dimensional filler 2 is broken rod 31 is broken and the elastic three-dimensional filler 2 is broken rod 31 is broken, and the elastic three-dimensional filler is broken rod 31 is further deformed under the elastic three-dimensional filler 2, so that the elastic three-dimensional filler 2 is broken material is broken when the elastic three-dimensional filler 2.
