A filtering and sedimentation method for water resource ecological environment treatment, based on the filtering and sedimentation device for water resource ecological environment treatment described in claims 1-8, characterized in that, The method steps include the following: S1. Liquid inlet: The water source to be treated is connected to the upper end of the liquid inlet pipe (41), and introduced into the upper fixed frame (11) and the inside of the device body (1). The water source is initially precipitated inside the device body (1); S2, automatic filtration and sedimentation: starting the drive motor (51) to drive the drive shaft (58) and the drive gear (52) to rotate, so that the fixed plate (581) and the clamping plate (582) drive the adsorption filter plate (59) to flip, adsorbing harmful substances in the water, improving the water quality, and filtering and purifying larger particles and suspended solids through the multiple filter holes inside the filter bottom plate (6) and gradually settling to the sedimentation tank (13) at the bottom; S3, extended sedimentation: the driving gear (52) drives the fixed gear (54) and the rotating rod (56) to rotate through the transmission gear belt (53), and the multi-leaf filter cartridge (57) on the rotating rod (56) rotates accordingly, filtering the water source. The treated water source enters the extended sedimentation tank (2) for secondary sedimentation, and the fine particles and suspended matter in the water source further settle to the bottom; S4. Sediment discharge: When the sediment accumulates to a certain extent, the baffle plate 1 (132) and the sealing plate 1 (131) at the front end of the sedimentation tank (13) are opened to clean and discharge the sediment. After completion, the baffle plate 1 (132) and the sealing plate 1 (131) are closed to ensure that the sedimentation tank (13) is in a sealed state; Open the baffle plate 2 (221) and the sealing plate 2 (222) inside the sedimentation tube (22) to clean and discharge the sediment, and after completion, close the baffle plate 2 (221) and the sealing plate 2 (222) to ensure that the sedimentation tube (22) is in a sealed state; S5. Water collection: The water source after sedimentation and filtration is discharged through the liquid outlet pipe (3) and the treated water source is collected into a designated container or pipeline.
