Abstract

PURPOSE:To easily seal a generated malodorant and harmful gas by a liquid by flowing a sealing liquid with a low specific gravity into a surface of a liquid substance such as a waste water in an opened condition. CONSTITUTION:In a precipitation separation tank or the like of an ammonia containing waste water treating procedure, NH3 is generated from a charging port 3, a liquid level 1 and a water passage part 4. To a surface of a liquid substance such as said waste water, a nonvolatile liquid such as a liquid paraffin which has a specific gravity lower than that of said liquid substance, low solubility thereagainst and is not reacted chemically therewith is thrown to seal said liquid substance. As a result, the generation of the malodorant and harmful gas such as an ammonia vapor from the liquid surface is eliminated and working enviroment is improved. Moreover, the used fluid paraffin is stable against heat, sunlight or components in the waste liquid and suitable as a sealing liquid because it is harmless and handled easily.
