[0027] In the embodiment, the aeration cavity 110 is arranged on the advanced oxidation tank 100, the rotating frame 210 of the filler mechanism 200 and the ROS aerator 300 are sequentially and vertically spaced in the aeration cavity 110, each filler barrel 220 is arranged on the rotating frame 210 and can rotate with the rotating frame 210, the filler cavity 221 of the filler barrel 220 communicates with the aeration cavity 110 through the water-permeable holes 222, and the iron-carbon filler bodies 230 are arranged in the filler cavity 221, so that the ROS aerator 300 is used to aerate the wastewater, the rotating frame 210 drives the filler barrel 220 to rotate, so that the iron-carbon filler bodies 230 in the filler cavity 221 fully contact with the wastewater, not only the piezoelectric catalysis effect is generated to produce active oxygen to oxidize and decompose the organic pollutants in the wastewater, but also the micro-electrolysis effect of the iron-carbon filler is used to form a micro-battery effect to further efficiently degrade the refractory substances in the wastewater, and the two can efficiently and synergistically oxidize, which can significantly enhance the advanced oxidation effect and improve the degradation capacity of the pollutants, so as to have a better advanced oxidation effect.

[0028] In one embodiment, as Figure 2 and Figure 3As shown, the rotating frame 210 comprises a rotating shaft 211 and a plurality of rotating frames 212, the rotating shaft 211 is rotatably arranged in the aeration cavity 110, each rotating frame 212 is annularly arranged on the rotating shaft 211, and each filler cylinder 220 is arranged in each rotating frame 212. Specifically, the rotating frame 212 is a square frame, each rotating frame 212 is uniformly annularly arranged on the rotating shaft 211, that is, the included angle between each two adjacent rotating frames 212 is equal, and each filler cylinder 220 is arranged in multiple groups, and the filler cylinders 220 in each group are uniformly distributed in a rotating frame 212. In this way, as the rotating shaft 211 rotates, the iron-carbon filler body 230 in the filler cylinder 220 can be more fully contacted with the wastewater, and the micro-electrolysis effect of the iron-carbon filler can be better formed to efficiently degrade the refractory substances in the wastewater through the micro-battery effect.

[0029] In one embodiment, the combined ROS advanced oxidation treatment equipment 10 further comprises a driver arranged on the advanced oxidation tank 100 and drivingly connected with the rotating shaft 211. Specifically, through the driving connection between the driver and the rotating shaft 211, the driver can drive the rotating shaft 211 to rotate in the aeration cavity 110, drive the rotating frame 212 and the filler cylinder 220 on the rotating frame 212 to rotate, and thus drive the rotating frame 210 to rotate in the aeration cavity 110, so that the iron-carbon filler body 230 in the filler cylinder 220 can be fully contacted with the wastewater.

[0030] In one embodiment, the filler cylinder 220 is rotatably arranged in the rotating frame 212. Specifically, by rotating the filler cylinder 220 in the rotating frame 212, the filler cylinder 220 can rotate relative to the rotating frame 212 while rotating in the aeration cavity 110 along with the rotating frame 212, that is, the filler cylinder 220 can rotate relative to the rotating frame 212 under the action of the gas flow generated by the ROS aerator 300, so that the iron-carbon filler body 230 in the filler cylinder 220 can be better contacted with the wastewater, thereby further promoting the micro-electrolysis effect of the iron-carbon filler to form the micro-battery effect and efficiently degrade the refractory substances in the wastewater.

[0031] In one embodiment, a plurality of limiting rings are arranged on the side wall of the filler cavity 221, and each limiting ring is uniformly and spacedly arranged. Specifically, by arranging the limiting rings in the filler cylinder 220, the limiting effect can be achieved, and the iron-carbon filler bodies 230 can be uniformly distributed in the filler cavity 221, so that the iron-carbon filler bodies 230 can be uniformly distributed during the rotation of the filler cylinder 220 in the aeration cavity 110, thereby ensuring that the iron-carbon filler bodies 230 can be more fully contacted with the wastewater.

[0032] In one embodiment, as shown in FIG. 6, the filler cylinder 220 comprises a filler cavity 221 and a plurality of iron-carbon filler bodies 230 arranged in the filler cavity 221. Specifically, the iron-carbon filler body 230 is a cylinder, and the filler cavity 221 is a hollow cylinder, and the iron-carbon filler body 230 is arranged in the filler cavity 221.

Specifically, the aerator disc body 310 is provided with an aeration channel, and the ROS microporous aeration membrane 320 is arranged on the aerator disc body 310 and aligned with one end of the aeration channel. In this way, when pressurized aeration is performed, air can act on the ROS microporous aeration membrane 320 through the aeration channel, and then pass through the ROS microporous aeration membrane 320 to be aerated outward, thereby realizing micro-nano bubble aeration in the aeration cavity 110. The ROS microporous aeration membrane 320 is a polyethylene microporous aeration membrane. Since the polyethylene microporous aeration membrane has the characteristics of high membrane porosity, ultra-large specific surface area, low aeration resistance, near-zero pore size deformation, acid and alkali resistance, and high salt resistance, the airflow fully passing through the polyethylene microporous aeration membrane can produce smaller bubbles, the bubble density in a unit volume is larger, and the distribution is more uniform, the mass transfer coefficient is high, the oxygen transfer efficiency is higher, and piezoelectric catalysis can also occur to produce active oxygen, thereby better oxidizing and decomposing organic pollutants in wastewater.

[0033] In one embodiment, the combined ROS advanced oxidation treatment equipment 10 further comprises: an aeration pump and an aeration pipe, the aeration pump is arranged in the advanced oxidation tank 100, the first end of the aeration pipe is connected with the aeration pump, and the second end of the aeration pipe is connected with the aerator disc body 310. Specifically, by arranging the aeration pump and the aeration pipe, the first end of the aeration pipe is drivenly connected with the aeration pump, and the second end of the aeration pipe is in communication with the aeration channel of the aerator disc body 310, so that the ROS aerator 300 driven by the aeration pump can realize micro-nano bubble aeration in the aeration cavity 110.

[0034] In one embodiment, the width of the water permeable hole 222 near one end of the filler cavity 221 is smaller than the width of the water permeable hole 222 away from the other end of the filler cavity 221. Specifically, by arranging the width of the first end of the water permeable hole 222 to be larger than the width of the second end, not only can the wastewater in the aeration cavity 110 be easily introduced into the filler cavity 221 to contact the iron-carbon filler body 230, but also the iron-carbon filler body 230 can be prevented from being separated from the filler cavity 221 to the aeration cavity 110, so that the iron-carbon filler body 230 can be stably accommodated in the filler cavity 221.

[0035] In one embodiment, as Figure 3As shown, the number of ROS aerators 300 is set to be multiple, and the filler mechanisms 200 are set to be multiple groups. Specifically, each ROS aerator 300 is uniformly distributed at the bottom of the aeration cavity 110, and each group of filler mechanisms 200 is uniformly distributed in the aeration cavity 110. The number of ROS aerators 300 and filler mechanisms 200 can be adjusted according to the aeration demand and the micro-electrolysis demand. In this embodiment, no specific limitation is made, so that the combined ROS advanced oxidation treatment equipment 10 can not only well produce active oxygen through piezocatalysis, but also well form a micro-battery effect through the micro-electrolysis of the iron-carbon filler to efficiently degrade the refractory substances in the wastewater, and has better advanced oxidation effect.
