The present invention relates to a filtering apparatus. The filtering apparatus comprises: a first perforated tube which is installed within a collecting well, and through which a plurality of first slits are formed; a second perforated tube which is inserted into the first perforated tube, and through which a plurality of second slits are formed; and a mesh member which is coupled to the second perforated tube while surrounding an outer circumferential surface of the second perforated tube. According to an embodiment of the present invention, an effect is provided in that entering silt or the like can be efficiently blocked via a multi-structure including the first perforated tube, the second perforated tube and the mesh member, thereby ensuring the quality and quantity of filtered water and increasing cost competitiveness compared to a conventional screen structure-based filtering apparatus. |
