An embodiment of the present invention relates to a filter which is included in a system which is mounted on a building or the like and treats and recycles rain water. Provided is the filter for treating and recycling rain water, the filter comprising: a rain water inflow portion (10) via which rain water is introduced from the outside thereof; a flow distribution device (640) which evenly distributes the introduced rain water; activated carbon filter units (610) which are disposed on one side of the flow distribution device (640) to be connected thereto, and filter out impurities included in the introduced rain water; red clay ball filter units (620) which are disposed on one sides of the activated carbon filter units (610), and filter rain water, having passed through the activated carbon filter units (610), again by using filters including porous red clay balls; hydroxyapatite (HAp) filter units (630) which are disposed on one sides of the red clay ball filter units (620), and filter out bacteria and microorganisms remaining in rain water having passed through the red clay ball filter units (620) by adsorbing the bacteria and the microorganisms; an ultraviolet (UV) lamp unit (650) which is disposed on one sides of the hydroxyapatite (HAp) filters (630), and eliminates microorganism remaining in rain water having passed through the hydroxyapatite (HAp) filters (630); and solenoid valves (660) which are disposed between the activated carbon filter units (610) and the red clay ball filter units (620), and control flow of a fluid inside a system for treating and recycling rain water in opposite directions. |
