The invention can explain its functional principle by the following modes of operation: in the actual use process, sewage is poured into the sedimentation tank 2 through the space between the two extrusion plates 24, and at the moment, due to the arrangement of the filter screen 19, some large-particle substances in the sewage are isolated on the filter screen 19, and the sewage is primarily filtered, so that the large-particle substances are prevented from entering the sedimentation tank 2;
when sewage enters the sedimentation tank 2, the floating plate 16 in the sedimentation tank 2 moves upwards to squeeze the folding air bag 18, so that the flocculant in the folding air bag 18 is pressed into the sedimentation tank 2 through the liquid outlet pipe 17, and other impurities in the sewage are adsorbed into flocculent by the flocculant, so that the flocculent is precipitated (when the sewage is discharged, the floating plate 16 moves downwards, so that the folding air bag 18 can be stretched, the flocculant is replenished into the sewage again, and the next use is convenient), and meanwhile, the quantity of the sprayed flocculant is changed along with the change of the sewage liquid level in the sedimentation tank 2;

Compared with the prior art, the rotary rod 7 rotates to drive the disc 23 and the supporting block 29 to rotate, so that the inner walls at the left side and the right side of the shaking groove 22 are supported to enable the filter screen 19 to shake left and right continuously, water drops adhered to the filter screen 19 can drop quickly through shaking, and the condition that sewage treatment efficiency is reduced due to slow dropping of sewage is avoided;
the left and right movement of the piston 9 generates gas to enter sewage, and bubbles are formed in the sewage to slow down the downward movement speed of the flocculant, so that the flocculant can adsorb more impurities, and the flocculation effect of the flocculant is improved;
through the left-right movement of the piston 9, the two extrusion plates 24 are continuously contacted with or separated from the two conductive plates, so that the two extrusion plates 24 are continuously moved relatively or oppositely to extrude the impurities easy to be coated with water, the water in the impurities easy to be coated with water is extruded, and the waste of water resources is reduced.
