The material collection assembly includes a right-angle plate 114, a first inclined hopper 115, a second inclined hopper 116, a track plate 117, and a lower pressure frame 118.

[0020] The processing and filtration unit is connected to the sedimentation tank 101; the mesh frame 102 is slidably connected to the sedimentation tank 101 and located on the inner wall of the sedimentation tank 101; the handle bracket 103 is fixedly connected to the mesh frame 102 and located above the mesh frame 102; the support base 104 is fixedly connected to the sedimentation tank 101 and located above the sedimentation tank 101, and the support base 104 is adapted to the handle bracket 103; the filter plate 105 is disposed on the inner wall of the mesh frame 102; and the trapezoidal rod 106 is fixedly connected to the mesh frame 102 and located on the inner wall of the mesh frame 102. Below 102, the mating plate 107 is rotatably connected to the trapezoidal rod 106 and is located on the outer side wall of the trapezoidal rod 106. The mating plate 107 is in contact with the filter plate 105. The aeration tank 108 is disposed on one side of the sedimentation tank 101. The input end of the pump body 109 is connected to the sedimentation tank 101 and is located on one side of the sedimentation tank 101. The output end of the pump body 109 is connected to the aeration tank 108 and is located on one side of the aeration tank 108. The aeration assembly is connected to the aeration tank 108. The material collection assembly is connected to the aeration tank 108.

[0021] In this embodiment, wastewater is poured into the settling tank 101, and flocculant is evenly sprinkled to cause suspended particles and colloids in the wastewater to aggregate into larger flocs and settle downwards. After filtration, the wastewater falls to the bottom of the settling tank 101 and is then pumped into the aeration tank 108 by the pump body 109 for treatment with the aeration assembly. After a period of use, the mesh frame 102 is pulled out using the handle 103, and the fitting plate 107 is rotated to remove the restriction on the filter plate 105, making it easier for workers to clean the filter plate 105 and the mesh frame 102. Then, the fitting plate 107 is flipped in the opposite direction so that it rotates around the trapezoidal rod 106 to limit the filter plate 105, and then the mesh frame 102 is inserted again so that the handle 103 contacts the support base 104. The material collection assembly is used to collect impurities in the aeration tank 108. By collecting flocculent sediment in this way, the workload of workers is reduced and the efficiency and quality of wastewater treatment are improved.

[0023] In this embodiment, the aerator 110 pressurizes air and sends it into the aeration pipe 111, which then distributes the air to each of the aeration heads 112. Finally, the aeration heads 112 release the air into the water in the form of tiny bubbles, thereby achieving the purpose of oxygenating the water and promoting water mixing.

[0024] Furthermore, the connecting pipe 113 is connected to the aeration tank 108 and is located on the outer wall of the aeration tank 108.

[0027] In the embodiment, the rolling sewage mixed impurities pass through the first inclined bucket 115 and the second inclined bucket 116 in turn, respectively filter the impurities contained in the bubbles by using the own holes, and then the right-angle plate 114 is extracted to clean the first inclined bucket 115 and the second inclined bucket 116, so as to avoid the backflow of too many impurities.

[0028] Further, the track plate 117 is fixedly connected with the aeration tank 108 and located at the outer side wall of the aeration tank 108, the lower pressing frame 118 is slidingly connected with the track plate 117 and located at the inner side wall of the track plate 117, and the lower pressing frame 118 is matched with the right-angle plate 114.

[0029] In the embodiment, when the right-angle plate 114 is fixed, the lower pressing frame 118 is pushed to slide in the track plate 117, so as to match the right-angle plate 114 and limit the movement of the right-angle plate 114; when the right-angle plate 114 is cleaned, the lower pressing frame 118 is only needed to be reversely moved, so the structure is simple and convenient for the staff to operate and use.
