PROBLEM TO BE SOLVED: To provide a contaminant removing apparatus which can enhance coagulation efficiency by providing an air column formation preventive material and further can enhance recovery efficiency by providing a contaminant removing blade. SOLUTION: The contaminant removing apparatus includes a cylindrical outer casing 6 and a swirl flow generating cylinder 7 provided on the lower part within the outer casing 6. A contaminant coagulating cylinder 8 in communication with the swirl flow generating cylinder 7, an intermediate cylinder 9 provided intermediate between the contaminant coagulating cylinder 8 and the outer casing 6, and the outer casing 6 are provided concentrically and triply on the upper part of the swirl flow generating cylinder 7 to constitute continuous flow paths 10, 11. A rod-like air column formation preventive material 12 is provided within the contaminant coagulating cylinder 8. A contaminant removing blade 13 for removing contaminants, which comprises a plurality of blades, is provided on the upper part of the contaminant coagulating cylinder 8 so that the plurality of blades are provided at equal intervals in the direction of the central axis of the contaminant coagulating cylinder 8. A foam separating cylinder 14 for separating foams, which ascend from the contaminant removing blade 13, is provided on the upper part of the contaminant removing blade 13 consecutively from the contaminant removing blade 13.
