The present invention relates to a device for measuring the pollution index of a filtration membrane which includes: a raw water supply part (200) supplying raw water to be measured; a plurality of filtration membranes (110, 120, 130) having different filtration properties; a plurality of path lines (21 a, 22a, 23a) connecting the plurality of filtration membranes (110, 120, 130) in parallel to the raw water supply part (200); a plurality of flow measuring parts (310a, 310b, 310c) installed on the outlet sides of the filtration membranes (110, 120, 130) to correspond to the respective filtration membranes (110, 120, 130), and measuring the flow rate of raw water passed through the filtration membranes (110, 120, 130); at least one auxiliary filtration membrane (140a,140b) installed on the inlet side of at least one of the plurality of filtration membranes (110, 120, 130), and having a different filtration characteristic from that of the at least one filtration membrane (110, 120, 130); and a pollution index measuring part (400) measuring the pollution indexes of the filtration membranes (110, 120, 130) on the basis of the flow rates measured by the flow rate measuring parts (310a, 310b, 310c).
