処理されていたところである。The conventional odor in public toilets is that the tap water usually stored in a tank in the toilet is flushed periodically or each time it is used. In addition, for the treatment of harmful organic solvents having a bad odor such as sulfur oxides in a food factory and an irritating odor in a coating factory, a method is known in which mixed air at the generation site is taken into an exhaust duct and passed through a filter. In the treatment of scattered spray paint, a water curtain or a water filling tank is installed behind or below the object to be coated, and the residual spray paint is dropped onto the water curtain or the water surface and collected together with water. It is fresh.
