Abstract

The invention relates to a device for removing malodor of sewage which is arranged underground of edge of urban road and used for leading underground drainage, and providing clean city environment. The device is provided with a malodor removing tower for sucking malodor air in the sewage and discharging the malodor air to atmosphere, a discharging fan and a filtering core for removing the malodor are arranged in the malodor removing tower, so that the malodor of the sewage is filtered when passing through the malodor removing tower, a unidirectional damper for draining rainwater is arranged on a access opening of the sewage, and an aeration part capable of adjusting opening degree is formed on the unidirectional damper. The invention can removes malodor generated by the sewage through the malodor removing tower and avoids the malodor from dispersing in atmospheric environment through the access opening of the sewage. The outside of the malodor removing tower can be used as poster board and municipal propaganda column, thereby improving urban environment.

Description

technical field [0001] The invention relates to a deodorizing device, in particular to a sewer stench removal device for removing stench from a sewer arranged underground at the edge of a city street and diverting underground drainage to provide a clean urban environment. Background technique [0002] figure 1 is the schematic diagram of the section of the existing sewer, such as figure 1 As shown, the sewer 10 is provided with a manhole 11 . There are sewers underground on the side of the city streets. On the sewers where domestic sewage is diverted to the sewage treatment plant, manholes are provided at regular intervals on the sewers to allow rainwater or cleaning water on the ground surface to flow in. However, if the domestic sewage flowing into the sewer is stagnant, it tends to become rancid in summer, and emits a bad smell through the manhole, which brings discomfort to people and has a negative impact on the environment. [0003] In order to prevent the odor from...
