The top of the stirring rod 89 is rotatably connected to a support bar 891 through a bearing. The support bar 891 is fixedly connected to the box body 1. By designing the stirring mechanism 8, the sewage can be stirred.

[0022] Please refer to Figure 1 and Figure 2 and Figure 3 and Figure 4 As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the filtering mechanism 9 includes a filter screen 91. The filter screen 91 is slidably sleeved inside the sewage tank 5. A pull rod 92 is fixedly sleeved inside the filter screen 91. The bottom of the pull rod 92 contacts the sewage tank 5. A fixing seat 93 is slidably sleeved on the outside of the pull rod 92. A guide rod 94 is slidably sleeved inside the fixing seat 93. A spring 95 is arranged on the outside of the guide rod 94.

[0023] The specific implementation process of the present utility model is as follows: When in use, sewage is first added into the interior of the sewage tank 5. Under the action of the filter screen 91, the sewage can be filtered. Filtering the sewage can prevent impurities from entering the interior of the device and causing blockages, which will affect the subsequent sewage treatment work. When the sewage enters, the liquid delivery pipe 10 inputs the treatment liquid into the rotating pipe 7. The treatment liquid is sprayed through the spray head 85 and contacts the sewage to carry out treatment. During the treatment process, the output end of the motor 81 drives the first gear 82 and the second gear 83 to rotate, so that the rotating pipe 7 drives the spray head 85 to rotate and spray. At the same time, the rotating pipe 7 drives the third gear 87 to rotate, so that the fourth gear 88 drives the stirring rod 89 to rotate. The stirring rod 89 rotates in the opposite direction to the spray head 85, which can make the contact between the sewage and the treatment liquid more uniform and complete, helping to improve the sewage treatment reaction efficiency. When the sewage reaction is completed, the precipitation and aeration work can be carried out.

[0024] When it is necessary to disassemble the filter screen 91, directly pull up the pull rod 92. The pull rod 92 drives the filter screen 91 to move. At the same time, the pull rod 92 slides relative to the fixed seat 93 and the ball 97. The extrusion of the pull rod 92 on the ball 97 can make the ball 97 drive the slider 96 to move horizontally. The extrusion of the slider 96 on the spring 95 can separate the groove 98 from the ball 97. At this time, continuously moving the pull rod 92 can take out the filter screen 91, which is convenient for the subsequent recovery and treatment of the filtered impurities and the like.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
