The inner wall of the stripping tube (118) is coated with a smooth coating. A shaking component is provided between the guide tube (119) and the stripping tube (118) so that the stripping tube (118) can peel off the solid impurities adhering to its inner wall by shaking.

9. A wastewater reuse device for landscaping and greening according to claim 8, characterized in that, The jitter component includes: Multiple connecting slots are connected to the upper and lower ends of the guide tube (119). A round-headed rod (121) is slidably connected in the connecting slot. The bottom end of the round-headed rod (121) extends to the bottom of the guide tube (119) and is fixed to the top end of the unloading tube (118). A second spring (122) is fixed between the round-headed rod (121) and the connecting slot. The drive ring (123) is located above the guide tube (119) and is rotatably connected to the inner wall of the pretreatment tank (102). The top of the round-headed rod (121) is spherical and movably fits against the bottom of the drive ring (123). The bottom of the drive ring (123) is fixedly connected with a plurality of downwardly protruding arc-shaped ramps (124) at intervals. The side of the arc-shaped ramp (124) facing the drive ring (123) is an arc-shaped slope. A concave rod (126) is located above the drive ring (123) and fixed to the outer wall of the connecting shaft (106). The concave rod (126) is a U-shaped rod with both ends bent downwards. A mating hole (125) is provided at the top of the drive ring (123) and below the concave rod (126).

10. The method of using a wastewater reuse device for landscaping water conservation according to any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Garden wastewater enters the trumpet pipe (103) through the inlet pipe (101), and then passes through the filter screen (107) to separate larger solid impurities. The treated wastewater then enters the treatment tank (100) through the connecting pipe (127), corrugated pipe (128), and outlet pipe (130). After passing through the sedimentation zone and water purification and disinfection mechanism in the treatment tank (100), it can be discharged through the drain pipe for reuse. Step 2: After cleaning the filter screen ( When solid impurities remain on 107), the electric lifting rod (113) provides downward thrust to the connecting shaft (106), causing the horn tube (103) and the bearing ring (104) to move downward synchronously. When the insertion block (111) on the side wall of the horn tube (103) moves down to the positioning lock groove (120) on the inner wall of the guide tube (119), the insertion block (111) is inserted into the positioning lock groove (120) by the thrust provided by the first spring (112). At the same time, the other end of the insertion block (111) The tube (103) exits through the through hole on the insert (108), thereby keeping the horn tube (103) and guide tube (119) fixed while releasing the locking state between them and the bearing ring (104). This allows the connecting shaft (106) to continue driving the bearing ring (104) to move down to the inside of the unloading tube (118). Once in position, the servo motor (116) starts, and through the meshing transmission action of the drive gear (115) and transmission gear (114), the connecting shaft (106) drives the bearing ring (104) to rotate. The filter screen (107) and the top of the support ring (104) have the same slope. With the centrifugal force generated by the rotation of the support ring (104) and the filter screen (107), the solid impurities remaining on the filter screen (107) can be removed, thus cleaning the filter screen (107). After the support ring (104) rotates to the initial position and stops, the electric lifting rod (113) drives it to rise and reset. The solid impurities fall into the surface of the receiving hood (117) for separate collection.
