DRAINAGE SYSTEM EQUIPMENT FOR REDUCING ODOR IN WATERFALL SEWER PIPE

摘要

The purpose of the present invention is to provide a drainage system for reducing the stench of a sewer pipe having a head/stepped portion capable of creating a pleasant environment by physically reducing the diffusion of hydrogen sulfide in the sewer pipe having a head or a stepped portion through the head or the stepped portion and removing the displeasure caused by the stench, and preventing an explosion caused by gas that accumulated in a manhole. To achieve this purpose, the present invention is to provide a drainage system for reducing the stench of the sewer pipe having the head/stepped portion comprising: a pipe body wherein sewage flows in; a sewage inflow pipe which is connected and formed on a wall of a side higher than the bottom of the pipe body; and a dripping water prevention unit which is placed on the front side of the sewage inflow pipe and guides the flowed sewage to the lower side of the pipe body.
