[0054] As another specific solution, the structure shown below is provided.

[0055] In this embodiment, the processing device is similar to the above scheme, mainly including an ozone generation metering system 24, an ozone contact reaction system 23, a water inlet system 21, and an exhaust gas absorption system 22.

[0056] The ozone generation and metering system 24 includes: an integrated ozone generator 18, an ozone concentration meter 19, and a gas flow meter 20; the ozone contact reaction system 23 includes: a square stainless steel base 1, a water inlet pipe 2, an air inlet pipe 3, a drain pipe 4, a check valve 5, a drain valve 6, an aeration head 7, an inner reaction column 8, an outer reaction column 9, a catalyst support perforated plate 10, a sealing ring 11, a flange 12, a top overflow port 13, a top cover sealing ring 14, a top cover 15, a top water outlet 16, and an exhaust pipe 17. The water inlet system 21 includes: a water inlet pipe 2, a stainless steel filter screen for the water inlet pipe 2, and a water pump.

[0057] The square stainless steel base 1 serves as the support for the ozone contact reactor. The bottoms of the inner and outer reaction columns 9 are welded to this stainless steel base via argon arc welding. The interfaces of the water inlet pipe 2, air inlet pipe 3, and drain pipe 4 are connected to the stainless steel base via argon arc welding. The water inlet pipe 2, air inlet pipe 3, drain pipe 4, check valve 5, and drain valve 6 are all made of PVC and are connected via heat fusion.

[0063] After the reaction is complete, the remaining gas in the device is discharged into the tail gas absorption device through the tail gas collection pipe.

[0064] The principle of the catalytic oxidation of small micro-black and odorous water bodies by ozone is as follows:

[0065] By virtue of the strong oxidizing property of ozone and the catalytic action of the catalyst, part of the ozone is decomposed into oxygen free radicals and hydroxyl free radicals, which have extremely strong oxidizing capacity and can decompose organic pollutants into relatively simple, harmless molecules and ions. This helps to improve the water quality of the water body and reduce the odor.

[0066] Based on any of the above devices, specific experimental embodiments are provided.
