[0025] The effect achieved by the entire embodiment 1 is that when the sewage is disinfected, the sewage is first discharged into the sedimentation tank 4, and the sewage is precipitated in the sedimentation tank 4 for a period of time, so that larger impurities such as sludge in the sewage will gradually settle at the bottom, and then the solenoid valve on the outer surface of the water inlet pipe 5 near the bottom side is opened to connect the water inlet pipe 5 with the sedimentation tank 4. The sedimentation tank 4 is located on the top side of the filter box 3. Under the action of gravity, the sewage will flow downward from multiple through holes evenly opened on the surface of the water inlet pipe 5 into the filter frame 8. The filter frame 8 is provided with multiple layers of filter plates, and the coarse filter screen plate on the top layer will further filter the impurities in the sewage. The fine filter screen is near the middle layer, which further filters the impurities in the sewage. The activated carbon plate is at the bottom layer, which can adsorb the bacteria and some viruses in the activated carbon plate. After being filtered and adsorbed, the sewage is temporarily stored in the filter box 3. The pump body 6 is started, and the pump body 6 will pump the stored sewage outward, and the sewage enters the second disinfection box 202 through the second delivery pipe 7, and flows to the bottom of the second disinfection box 202 along the guide plate 206. The multiple first disinfection lamps 205 are started synchronously, and the first disinfection lamps 205 will emit ultraviolet rays to fully irradiate the sewage overflowing from the guide plate 206, thereby playing a role in preliminary disinfection of the sewage. The sewage at the bottom of the second disinfection box 202 will flow from the first delivery pipe 207 to the outlet pipe 208 under the action of the continuous inflow of sewage pressure. The outer surface of the outlet pipe 208 is an oblate cylinder with a larger cross-section near the top side, and a plurality of through holes are evenly opened on its surface, so that the sewage can flow from the bottom to the bottom of the transition box 209 to avoid the sewage from being directly sprayed upward. When the sewage in the transition box 209 gradually rises until it is higher than the plurality of overflow holes 212, the sewage inside it will be discharged from the plurality of overflow holes 212 on both sides. Mounting blocks 210 are respectively fixed on the tops of the plurality of overflow holes 212 on both sides. When the two mounting blocks 210 are opened, The inner surface of the mounting block 210 is symmetrically provided with second disinfection lamps 211. The plurality of second disinfection lamps 211 will irradiate the overflowing sewage with ultraviolet rays again, so that the viruses and bacteria in the sewage after the initial disinfection will be killed again. The sewage after disinfection will be discharged from the drain pipe arranged on one side of the first disinfection box 201. After the sewage is precipitated and filtered, the plurality of overflow holes 212 arranged on both sides of the guide plate 206 and the transition box 209 cooperate to increase the irradiation time of the sewage, so that the sewage can maintain a slow flow rate and be fully irradiated and disinfected by the ultraviolet light, thereby improving the disinfection effect of the disinfection mechanism of the sewage treatment equipment.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, the guide plate 206 is inclined and located in the middle of the first disinfection box 201 . The rear surface of the second disinfection box 202 is rotatably connected to the rear surface of the box cover 203 via a hinge, and a reflector 204 is provided on the inner top surface of the box cover 203 .

[0027] The effect achieved by the entire embodiment 2 is that, when in use, by arranging a reflector 204 on the inner top surface of the box cover 203, the ultraviolet rays emitted by the multiple first disinfection lamps 205 can be reflected downward, preventing the ultraviolet rays of the multiple first disinfection lamps 205 from diffusing upward, affecting the multiple first disinfection lamps 205 to disinfect and kill sewage, and further improving the disinfection effect of the disinfection mechanism of the sewage treatment equipment.

[0028] Working principle: When the sewage is disinfected, it is first discharged into the sedimentation tank 4. The sewage is precipitated in the sedimentation tank 4 for a period of time, so that larger impurities such as sludge in the sewage will gradually settle at the bottom. Then, the solenoid valve on the outer surface of the water inlet pipe 5 near the bottom is opened to connect the water inlet pipe 5 with the sedimentation tank 4. The sedimentation tank 4 is located on the top side of the filter box 3. Under the action of gravity, the sewage will flow downward from multiple through holes evenly opened on the surface of the water inlet pipe 5 into the filter frame 8. A plurality of filter plates are arranged in the filter frame 8. The coarse filter screen plate on the top layer will further filter the impurities in the sewage. The fine filter screen plate near the middle layer will further filter the impurities in the sewage. The activated carbon is at the bottom layer. The activated carbon plate can adsorb bacteria and some viruses in the activated carbon plate. After being filtered and adsorbed, the sewage is temporarily stored in the filter box 3. The pump body 6 is started, and the pump body 6 will pump the stored sewage outward, and enter the second disinfection box 202 through the second delivery pipe 7, and flow to the bottom of the second disinfection box 202 along the guide plate 206. The multiple first disinfection lamps 205 are started synchronously, and the first disinfection lamps 205 will emit ultraviolet rays to fully irradiate the sewage overflowing on the guide plate 206, which plays a role in preliminary disinfection of the sewage. The sewage at the bottom of the second disinfection box 202 will flow from the first delivery pipe 207 to the outlet pipe 208 under the pressure of the continuously flowing sewage, and the outer surface of the outlet pipe 208 The oblate cylinder with a larger cross-section on one side near the top has multiple through holes evenly opened on its surface, which can make the sewage flow out from bottom to top to the bottom of the transition box 209 to avoid the sewage from directly spraying upward. When the sewage in the transition box 209 gradually rises until it is higher than the multiple overflow holes 212, the sewage inside it will be discharged from the multiple overflow holes 212 on both sides. The tops of the multiple overflow holes 212 on both sides are respectively fixed with mounting blocks 210. The second disinfection lamps 211 symmetrically arranged on the inner surfaces of the two mounting blocks 210 are turned on, and the multiple second disinfection lamps 211 will irradiate the overflowing sewage with ultraviolet rays again, so that the viruses and bacteria in the sewage after the initial disinfection are killed again. The sewage after disinfection will be discharged from the first disinfection lamp. The sewage is discharged through a drain pipe arranged on one side of the poison box 201. After the sewage is precipitated and filtered, it cooperates with the guide plate 206 and the multiple overflow holes 212 arranged on both sides of the transition box 209 to increase the exposure time of the sewage, so that the sewage can maintain a slow flow rate and be fully irradiated and disinfected by the ultraviolet light, thereby improving the disinfection effect of the disinfection mechanism of the sewage treatment equipment. By arranging a reflector 204 on the inner top surface of the box cover 203, the ultraviolet rays emitted by the multiple first disinfection lamps 205 can be reflected downward to prevent the ultraviolet rays of the multiple first disinfection lamps 205 from diffusing upward, affecting the multiple first disinfection lamps 205 from disinfecting and killing the sewage, thereby further improving the disinfection effect of the disinfection mechanism of the sewage treatment equipment.
