(57) [Summary] [Structure] A deodorizing material mainly composed of a phosphate compound and an iron sulfate salt that make a malodor source non-volatile, and a magnesium compound that makes a non-volatile compound hardly soluble. A deodorizing material in which lime superphosphate, lime superphosphate and the like are used, and magnesium compounds such as magnesium sulfate, magnesium hydroxide, magnesium oxide and magnesium phosphates are used. [Effect] It is possible to effectively remove offensive odors such as livestock excrement, and since the offensive odor source is contained as a sparingly soluble compound, there is no problem of secondary pollution of the environment even if the treated wastewater is discharged, and Since the untreated product from which the bad odor has been removed contains fertilizer components such as nitrogen, phosphoric acid and potassium, this can be effectively used as a slow-release fertilizer. |
