[0029] Embodiment 1:

[0030] Combination Figure 2-Figure 5 The fixing assembly 4 includes a block 401 which slides in the top opening of the fixing plate 301. One side of the block 401 passes through the side wall of the fixing plate 301 and is inserted into the opening of the side wall of the annular placement plate 101. A spring 402 is fixed on the other side. The spring 402 is fixed to the inner wall of the fixing plate 301. A push-pull plate 403 is fixed on the top of the block 401. A rubber block 4011 is provided on the fixed side of the block 401. When in use, the push-pull plate 403 is pulled backward to drive the block 401 to move backward, and the spring 402 is compressed to move the fixing plate 301. After 01 is placed on the top of the annular placement plate 101, the push-pull plate 403 is released, and the elastic force of the spring 402 pushes the block 401 forward and enters the opening of the side wall of the annular placement plate 101, and the fixation is completed.

When placing the fixed plate 301, the protrusion 3011 is inserted into the top opening of the annular placement plate 101 to complete the initial positioning. Protrusions 3011 are provided at the bottom of the fixed plate 301, which can achieve precise positioning when placing the fixed plate 301, improve the stability of the device, and prevent the fixed plate 301 from being displaced, which affects the production effect.

[0033] Embodiment 2:

[0034] Combination Figure 1-Figure 2 The water inlet bucket 201 is fixed on the top of the box cover 2 by threaded connection, and a grille 2011 is fixed inside the water inlet bucket 201. The threaded connection between the water inlet bucket 201 and the box cover 2 is simple and firm to use, and has high safety. Fixing the water inlet bucket 201 inside the water inlet bucket 201 can effectively remove large particles and floating objects in the sewage, providing convenience for subsequent treatment. When accumulation affects the movement of water flow, it is only necessary to disassemble the water inlet bucket 201 separately, without dismantling the entire device.

[0035] A water outlet 102 is opened at the lower position of one side of the filter box 1, and a valve 1021 is arranged on the water outlet 102. The water outlet 102 is opened at the bottom of the filter box 1, and the water flow can be collected without adding a pumping device, and the valve 1021 is arranged on the water outlet 102, which can effectively control the release of water flow and improve production safety.

[0036] Embodiment three:

[0037] Combination Figure 2-Figure 4 The first filter element 303 is made of polypropylene, the second filter element 304 is made of activated carbon, and the third filter element 305 is made of ultrafiltration membrane. The polypropylene filter element has a large filtration area and high filtration accuracy, and can effectively remove large particles of impurities, suspended matter, sediment, etc. in sewage. The activated carbon filter element is mainly used to remove organic matter, odor and color in sewage. The activated carbon has strong adsorption performance and can effectively absorb harmful substances in sewage and improve water quality. The ultrafiltration membrane filter element has higher filtration accuracy and can further remove tiny particles, bacteria, viruses, etc. in sewage.

[0038] A handle 307 is fixed on the top of the first filter element 303, the second filter element 304 and the third filter element 305. The handle 307 fixed on the top of the filter element facilitates the subsequent removal of the filter element and collection of filter residues, providing convenience for operation.
