2. The constructed wetland device for urban runoff filtration treatment according to claim 1, wherein: the filter screen (51) is of a hollow cylindrical structure, and the annular wall and the top wall and the bottom wall are provided with filter holes.
3. The method for using an artificial wetland device for urban runoff filtration treatment according to any one of claims 1-2, characterized by comprising the following steps:
s1, firstly, a round hole (31) of a slag receiving cylinder (3) penetrates through a drain pipe (42) of a drain assembly (4), the slag receiving cylinder (3) is connected with a guide cylinder (21) of a guide assembly (2) through a threaded structure, meanwhile, the slag receiving cylinder (3) is sleeved outside a filter assembly (5), and then the end part of the drain pipe (42) of the drain assembly (4) is fixedly connected with an L-shaped drain pipe (41) through the threaded structure, so that the device can be assembled;
S2, after the assembly is completed, the invention is arranged in the artificial wetland unit, and meanwhile, the water outlet of the L-shaped water outlet pipe (41) extends into the artificial wetland unit, and the guide cylinder (21) and the slag receiving cylinder (3) are positioned in the soil layer of the artificial wetland unit;
S3, the water source of urban runoff flows into the constructed wetland unit, the water source enters between the first volute plate (12), the second volute plate (13) and the third volute plate (14) respectively under the drainage of the drainage component (1), then the water source gathers and flows into the through hole (15), the water source entering the through hole (15) is guided and turned through the spiral water channel (23) of the flow guiding component (2), the originally messy water flow keeps the flow direction consistent, then falls into the slag receiving cylinder (3) under the action of gravity, falls into the interior of the slag receiving cylinder (3), before the water flow impacts the turbine blade (53) of the filtering component (5), the turbine blade (53) is driven to rotate, the turbine blade (53) drives the connecting shaft (52) to rotate, the connecting shaft (52) drives the filter screen (51) to rotate, meanwhile, the water source inside the slag receiving cylinder (3) penetrates through the rotating filter screen (51), the filter screen (51) filters the water source, the filtered water source enters the drain pipe (42), finally the L-shaped drain pipe (41) is discharged into the constructed wetland unit, and the constructed wetland unit is used for reprocessing the filtered water source.
