PROBLEM TO BE SOLVED: To provide a deodorizing equipment for sewage treatment plant and pump yard which contribute to the environmental improvement of a sewage treatment plant and a pump yard by preventing odor from sewage works to a sewage inflow part from entering the sewage treatment plant and the pump yard. SOLUTION: In the deodorizing equipments, a float 4 is floated on the water surface WL of a sewage inflow part 2 of the sewage treatment plant and the pump yard 1, the lower end part 50 of a deodorizing screen 5 which extends in the width direction of the sewage inflow part 2 is attacked to the float 4 and the base end part 51 of the deodorizing screen 5 is attached to a roller 7 and is wound in a roller shape. Further, the roller 7 is freely rotatably held on a feeding/winding means 8 and is subjected to reversal rotation in the feeding direction and winding direction of the deodorizing screen 5 in accordance with a fluctuation of the water surface WL and, thereby, the communication state between a space 10 above the water surface of the sewage treatment plant and pumping plant 1 and a space 11 above the water surface of the sewage inflow part 2 is interrupted.
