By arranging a detachably connected disinfection part in the disinfection shell, the sewage is continuously disinfected, the disinfection sheet can be conveniently replaced, the operation is convenient, and the disinfection effect is good.

[0004] In the process of sewage disinfection, the existing disinfection device can only inject disinfectant from one side, so it is difficult for the disinfectant to be fully mixed into the sewage, resulting in poor disinfection effect on the sewage, and the bacteria and viruses in the sewage cannot be quickly killed. At the same time, the sewage contains a large amount of impurities and sediment, and this part of the sewage with a large impurity content cannot be effectively discharged during the disinfection process, so it is easy to block the pipe of the disinfection device for a long time, thereby reducing the sewage treatment efficiency and being inconvenient for practical use.

[0007] By adopting the above technical solution, the sand and impurities in the sewage are filtered by the filter screen and then precipitated and accumulated inside the disinfection tank. Then, the second motor is turned on to drive the spiral conveying force of the auger to discharge the impurities from the inside of the disinfection tank, thereby filtering the sewage and reducing the risk of the disinfection device being blocked; by driving the stirring rod to rotate around the surface of the filter tank, the second gear on the surface is engaged with the second fixed gear ring, so that the stirring rod can rotate synchronously, thereby improving the stirring effect of the sewage, improving the mixing efficiency of the sewage and the disinfectant inside the disinfection device, and ensuring the disinfection effect.

[0014] The utility model is further configured as follows: an observation window is fixedly connected to one side of the exterior of the disinfection tank.

[0015] The above technical solution makes it easy to observe the sewage treatment status inside the disinfection tank, so that the accumulated impurities can be discharged in time.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The sand and impurities in the sewage are filtered by the filter screen and then precipitated and accumulated inside the disinfection tank. Then the second motor is turned on to drive the spiral conveying force of the auger to discharge them from the inside of the disinfection tank, thereby filtering the sewage and reducing the risk of clogging of the disinfection device.

[0018] 2. By driving the stirring rod to rotate around the surface of the filter tank, the second gear on the surface is engaged with the second fixed gear ring, so that the stirring rod can rotate synchronously, thereby improving the stirring effect of the sewage, improving the mixing efficiency of the sewage and the disinfectant inside the disinfection device, and ensuring the disinfection effect.
