[0059] The lower end of the two filter boxes 4 is fixedly installed with a V-shaped pipe 411. (It should be noted that, because the suspended solids in the wastewater need to be removed, in order to ensure that the wastewater does not flow away directly, the position where the V-shaped pipe 411 is connected to the filter box 4 also needs to be designed to open and close, which has the same structure as the first sealing plate 304, which is used to temporarily prevent the wastewater in the filter box 4 from entering the inside of the V-shaped pipe 411. Therefore, the same structure as the lower end of the triangular pipe 204 needs to be provided on the outside of the V-shaped pipe 411 to throttle the wastewater in the filter box 4, but the specific structure or other structure can be designed and installed by the construction personnel as needed.)

The gap of the RO membrane 609 is very small and can only allow water to pass through, so as to complete the final filtration of the wastewater. It should be noted that when the wastewater is extruded, the extrusion rod 604 blocks the position where the cavity tube 605 and the lower connecting table 505 are connected, and only when the extrusion rod 604 is reset, the cavity tube 605 and the lower connecting table 505 are in a through state, so that the wastewater enters the inside of the cavity tube 605 again.
