[0041] Example 3: Based on Example 2, please refer to Figure 1-Figure 7 The present invention provides a method for treating garden sewage, which comprises the following steps:

[0042] S1: A processor is built into the bottom of the installation barrel 1, and the processor is electrically connected to the motor, the delivery pump, the electric push rod 3 and the liquid level sensor 14, and controls the electric push rod 3 to drive the installation sleeve 6 and the net cylinder 7 to move up and down, and guide the surface garbage into the filter net bag in the net cylinder 7 through the liquid level difference;

[0043] S2: The installation sleeve 6 and the net tube 7 move up and down, and the auxiliary rod 82 moves up and down through the chassis 9, and the auxiliary rod 82 rotates in coordination with the guide head 83 and the guide groove 84, so that the vibration rod 85 contacts the outer wall of the net tube 7 to generate vibration, thereby improving the garbage sinking effect;

[0044] S3: The auxiliary rod 82 rotates to open and close the sealing plate 10 through the opening and closing assembly, so that when the bottom plate 9 moves upward, the sealing plate 10 opens, and the water in the net tube 7 flows into the bottom space of the installation barrel 1; when the bottom plate 9 moves downward, the sealing plate 10 closes, and the water in the bottom space of the installation barrel 1 is squeezed out;

[0045] S4: The medicine in the medicine adding box 11 is delivered to the bottom space of the installation barrel 1 by a delivery pump, and discharged together with the water, so as to treat the sewage and improve the water environment, and the stirring blade 13 is driven by a motor to stir to avoid the deposition of the medicine;

[0046] S5: When the chassis 9 is moving upward, the liquid level inside the installation barrel 1 is sensed by the liquid level sensor 14, so that when it is blocked, the net cylinder 7 can be rotated to remove it and the filter net bag can be replaced.

[0047] Working principle: When using the garden sewage treatment device and the treatment method thereof, first put the filter net bag into the net tube 7, then put the net tube 7 and the installation sleeve 6 into the installation barrel 1, the docking piece 1 51 and the docking piece 2 52 are in a staggered state, and then rotate the net tube 7 and the installation sleeve 6, and turn the docking piece 2 52 into the limit area of ​​the docking piece 1 51. At the same time, the installation barrel 1 is placed in the water area, so that the top of the installation barrel 1 corresponds to the liquid level surface of the water area, and the electric push rod 3 drives the push ring 4 to move up and down, which can drive the net tube 7 and the installation sleeve 6 to move up and down. , using the liquid level difference, the garbage and sewage on the water surface enter the net cylinder 7, and the garbage is filtered through the filter net bag. In this process, the net cylinder 7 drives the auxiliary rod 82 to move up and down through the chassis 9, and under the guidance of the guide head 83 and the guide groove 84, the auxiliary rod 82 is driven to rotate, so that the vibration rod 85 can contact the net cylinder 7 and rotate with its elasticity, so that the vibration rod 85 can be separated from the net cylinder 7 and reset. Through vibration and the impact of water flow, the garbage is washed to the bottom of the filter net bag and accumulated, avoiding premature clogging of the entire filter net bag;

[0048] When the net cylinder 7 moves upward, the rotation of the auxiliary rod 82 drives the movable ring 122 to rotate through the friction force of the guide ring 121, so that the push head 123 is separated from the installation rod 124, and the sealing plate 10 is reset under the action of the elastic telescopic rod 125. At this time, the middle cavity of the chassis 9 is in an open state, and the sewage can flow into the bottom space of the installation barrel 1. When the net cylinder 7 moves downward, on the one hand, the garbage is being processed on the top, and on the other hand, the sealing plate 10 is closed, and the downward movement of the chassis 9 can squeeze out the bottom sewage. The one-way valve setting can prevent external water from entering the bottom space of the installation barrel 1 from the side. In this process, the medicine adding box 11 transports the medicine liquid to the sewage in the bottom space of the installation barrel 1 through the delivery pump to purify the sewage. At the same time, the motor drives the stirring blade 13 to rotate to prevent the medicine liquid from depositing. When blockage occurs, after the net cylinder 7 moves upward, the infiltration speed of the water flow therein slows down, and the liquid level sensor 14 senses the water level change, and a remote signal can be sent through the controller to remind the staff to replace the filter net bag.
