The present invention relates to a noise reduction device of a blastpipe for sewage and wastewater. In a sewage and wastewater treating device, a blastpipe used for supplying high-pressure air required for treating sewage and wastewater to the inside of an aeration tank and a bioreactor is improved and modified, wherein a noise, generated while high-pressure air remaining inside the blastpipe when the blastpipe is opened and closed is discharged into the atmosphere, can be reduced. Therefore, a cause of complaint filing caused by a noise from field operators and residents living in the neighborhood, can be fundamentally removed. |
