The second processing component 30 includes a second tank 31 and at least two sets of guide pipes 32. The second tank 31 is placed in the second accommodating space. Both ends of the two sets of guide pipes 32 are respectively connected to the first tank 21 and the second tank 31, and the connection positions of the two sets of guide pipes 32 correspond to the positions of the first stirring rack 231 and the second stirring rack 232.

[0031] According to the technical solution of this embodiment, a wastewater treatment device includes: a cabinet 10, a first treatment component 20, and a second treatment component 30.

The filter structure 22 includes a first filter screen 221 and a second filter screen 222, both disposed within the first tank 21. The first filter screen 221 performs primary filtration, and the second filter screen 222 performs secondary filtration. The first stirring structure 23 includes a first stirring frame 231 and a second stirring frame 232. The first stirring frame 231 is located above the first filter screen 221 and can stir the impurities filtered out in the primary filtration and provide centrifugal force. The second stirring frame 232 is located above the second filter screen 222 and can stir the impurities filtered out in the secondary filtration and provide centrifugal force. The second processing component 30 includes a second tank 31 and at least two sets of guide pipes 32. The second tank 31 is placed within a second accommodating space. Both ends of the two sets of guide pipes 32 are connected to the first tank 21 and the second tank 31, respectively, and the connection points of the two sets of guide pipes 32 correspond to the positions of the first stirring frame 231 and the second stirring frame 232. Therefore, the two sets of guide pipes 32 can guide the impurities filtered out in the first tank 21 through primary and secondary filtration to the second tank 31, preventing the filtered impurities from accumulating in the first tank 21 and thus not affecting the flow rate of the wastewater. The technical solution of this embodiment effectively solves the problem in the prior art where filtered impurities affect the flow rate of wastewater.

[0034] It should be noted that the second stirring rack 232 and the first stirring rack 231 have the same structure and the same connection method. The difference is that the interval between the multiple connecting rods of the second stirring rack 232 is smaller. The purpose of this setting is to provide a larger and more stable centrifugal force, which makes it easier to throw the impurities filtered out in the second stage into the second set of guide pipes 32.
