Two limit rods 36 and a reciprocating screw 34 are horizontally arranged inside the wastewater treatment tank 1 along the length direction, and the reciprocating screw 34 is located between the two limit rods 36;

[0031] The stirring mechanism 3 includes a moving block 31, a bearing 32 and a stirring blade 33. The stirring blade 33 is loaded with a photocatalyst. The stirring shaft of the stirring blade 33 is vertically arranged. The bearing 32 is sleeved at the bottom of the stirring shaft of the stirring blade 33 to form a stirring blade assembly.

The two groups of plug rods 39 inside the mounting block 37 are acted upon by the rebound force of the first spring 40, so that the plug rod 39 is plugged into the slots on both sides of the positioning groove 38, thereby fixing the mounting block 37 inside the positioning groove 38, making it convenient to disassemble and install the components for cleaning, and convenient to use.

[0035] When in use, the top plug-in block 44 is plugged into the installation groove 43 opened inside the lighting frame 42 through the ultraviolet lamp 45, and the ultraviolet lamp 45 is fixed inside the installation groove 43 through the connecting blocks 46 arranged on both sides of the ultraviolet lamp 45. The electric push rod 41 is fixed on the top of the moving block 31.

The fixing block 49 is adapted to the connecting block 46, and the fixing block 49 is plugged into the connecting block 46.

[0037] When in use, the interior of the connecting block 46 and the exterior of the fixing block 49 are both arc-shaped, and the connecting block 46 and the fixing block 49 are adapted to each other. After the connecting block 46 is plugged into the interior of the lighting frame 42, the fixing block 49 will be plugged into the interior of the connecting block 46, thereby fixing the plug-in block 44. The operation is simple and quick, and it is convenient to install and disassemble, and easy to use.

[0038] Furthermore, two groups of guide rods 50 are fixedly connected inside the operating groove 47, and the push plate 48 is arranged outside the guide rod 50, and the push plate 48 is slidably connected to the guide rod 50. The push plate 48 slides outside the guide rod 50 arranged inside the operating groove 47 under force, and the stability of the movement of the push plate 48 is improved by the guide rod 50, which is convenient to use.

[0040] In this embodiment, the servo motor 35 drives the reciprocating screw 34 to rotate inside the wastewater treatment tank 1, so that the moving block 31 is forced to reciprocate inside the wastewater treatment tank 1, and the moving block 31 drives the multiple groups of bearings 32 set on both sides to move, and the bearings 32 drive the stirring blades 33 to move, and the stirring blades 33 set inside the bearings 32 are in contact with the water body, so that the stirring blades 33 rotate inside the bearings 32, and the stirring blades are impacted by the incoming water flow and rotate (in a small range), so that the organic matter in the wastewater is fully contacted with the photocatalyst on the stirring blades, and the photocatalyst can also be added to the wastewater treatment tank 1, further improving the efficiency of wastewater treatment. However, when the stirring speed is too fast, the photocatalyst on the stirring blade is impacted by the water flow, and the added photocatalyst is over-dispersed in the reaction system, which may cause the scattering and reflection of light on the catalyst surface to increase, and reduce the photocatalytic efficiency. Therefore, this embodiment optimizes the structure of the stirring mechanism so that the stirring blades are slightly stirred.

[0041] When in use, the treated water inside the wastewater treatment tank 1 can be conveniently discharged through the set drain port 2, and the drain port 2 is sealed by the sealing plug 21, which is convenient for the use of the wastewater treatment tank 1.
