The irradiation rods are circumferentially arranged along the central line of the main aeration pipe.

The aeration branch pipes take the aeration main pipe as the center and are in a radial shape.

And an air inlet valve is arranged on the aeration main pipe.

The utility model has the beneficial effects that: the treatment tank adopts a middle partition wall divided into an aeration tank and a cavitation air flotation tank, an air blower supplies air for an aeration branch pipe and an aeration disc in the aeration tank through an aeration main pipe, an irradiation rod is arranged on a separation plate in a cage type, and a protective cover is arranged on the outer side of the separation plate to prevent suspended matters and the like from falling onto the irradiation rod. In the cavitation air flotation tank, a chain type mud scraper is matched with a slag collection tank to remove floating slag in water. Chemical agents are not needed to be added in the irradiation disinfection process, disinfection byproducts are not generated in the disinfection dosage range, the method is a green and environment-friendly disinfection process, and meanwhile, the phenomena of UV light reactivation and dark reactivation are avoided. The aeration generates micro bubbles, so that the interior of the sewage continuously moves, and suspended matters and the like are not suitable to fall on the surface of the protective cover. Meanwhile, oxygen brought by aeration can react with irradiation and medium water to form high-activity free radicals, so that the disinfection effect is further enhanced, the irradiation intensity can be indirectly reduced, and the cost is greatly saved. Free radicals generated by irradiation and medium water can efficiently kill microorganisms in water, and can also generate chain reaction with other pollutants such as organic matters in water, and pollutants in water can be indiscriminately degraded, so that various water quality indexes of sewage are effectively improved.
