[0033] When the equipment is running, the water supply equipment injects the antibiotic wastewater to be treated into the inner cavity of the aeration shell 21 through one of the input ends of the aeration shell 21, so that the antibiotic wastewater enters the inner cavity of the cylinder body 11 through the first aeration hole 22 and the second aeration hole 26.

The auxiliary catalytic gas includes but is not limited to oxygen or ozone or a mixed gas of oxygen and ozone. After the auxiliary catalytic gas enters the inner cavity of the aeration shell 21, it flows through the first aeration hole 22 and the second aeration hole 26 in sequence into the cylinder body 11, and a large number of microbubbles are generated in the inner cavity of the cylinder body 11.

Moreover, during the rotation of the turntable 25, after the second explosion hole opened on the turntable 25 is completely offset from the first explosion hole opened on the bottom wall of the inner cavity of the cylinder body 11, the first explosion hole is closed, so that the auxiliary catalytic gas injected into the inner cavity of the aeration shell 21 can be released in batches by controlling the rotation of the turntable 25, so that the auxiliary catalytic gas entering the inner cavity of the aeration shell 21 is distributed more evenly in the upper part of the inner cavity of the aeration shell 21, thereby forming denser microbubbles in the inner cavity of the cylinder body 11, enhancing the adsorption efficiency of insoluble antibiotics and tiny particles in the antibiotic wastewater, and preventing the auxiliary catalytic gas located in the inner cavity of the aeration shell 21 from entering the inner cavity of the cylinder body 11 only through part of the first aeration hole 22 and the second aeration hole 26 close to the side of the gas supply device, thereby reducing the capture efficiency of insoluble antibiotics and tiny particles in the antibiotic wastewater.

[0035] Under lightless conditions, a pair of winding modules can control the third motor 55 to drive their reels 52 to rotate synchronously in the forward direction, so that the reel 52 of one winding module reels one end of the feeding belt 3, and the reel 52 of the other winding module releases the feeding belt 3, thereby utilizing the feeding belt 3 to bring the first catalyst stored in the storage box 51 of the other winding module into the antibiotic wastewater stored in the cylinder 11, and the pair of winding modules can adjust the input amount of the first catalyst by controlling the rotation angle of the reel 52, thereby achieving the purpose of degrading the antibiotic wastewater by mixing the first catalyst with the antibiotic wastewater.

[0036] Above, refer to Figures 1 to 6 The present invention describes an antibiotic continuous degradation device based on photocatalysis and light-free synergy according to an embodiment of the present invention, which has the following beneficial effects: 1. The device adds a pair of winding modules and a feeding belt 3, and uses the feeding belt 3 to quantitatively feed the first catalyst into the cylinder 11, so that it undergoes degradation reaction with the antibiotic wastewater under dark conditions, thereby reducing the energy consumption of the device when treating the antibiotic wastewater under dark conditions, and solving the defect of high operating energy consumption when treating the antibiotic wastewater under dark conditions in the prior art; 2. The device adds a feeding belt 3 in the cylinder 11 to form a mesh structure in the inner cavity of the cylinder 11, so that the microbubbles generated in the inner cavity of the cylinder 11 need to pass through the pores of the feeding belt 3 during the floating process, thereby increasing the density of the microbubbles; 3. When the user needs to take out the second catalyst 24 from the cylinder 11, the user can remove the pair of reels 52 of the winding module, hold the pair of reels 52 in hand and lift the feeding belt 3 upwards, and use the feeding belt 3 to fish out the second catalyst 24 floating on the water surface, thereby improving the convenience of using the device.
