The present invention provides a method of recycling a hydrogen sulfide remover, which is characterized by including the steps of : mixing yellow soil powder including iron oxide (Fe_2O_3), aluminum oxide (Al_2O_3) and silicon oxide (SiO_2), limonite including protein, carbohydrate and fat, and water and extruding the resultant mixture to prepare a hydrogen sulfide remover in a pellet shape; mixing the hydrogen sulfide remover with an object from which hydrogen sulfide is to be removed, to absorb hydrogen sulfide; collecting the hydrogen sulfide remover on which hydrogen sulfide be absorbed, to pulverize the hydrogen sulfide remover; neutralizing and recycling the hydrogen sulfide remover pulverized in a powder state; and drying the recycled hydrogen sulfide remover and supplementing yellow soil powder to prepare a hydrogen sulfide remover, wherein the iron oxide (Fe_2O_3) is included in 40 to 65% by weight. Accordingly, hydrogen sulfide that is a main cause of odor among domestic pollution can be effectively absorbed to be removed. A hydrogen sulfide remover includes yellow soil powder as a main ingredient, thereby removing, and also ammonia, oil, and phosphorus can be removed due to porosity, thereby effectively treating livestock excretion. In addition, a hydrogen sulfide remover can be prepared simply at low cost, and hydrogen sulfide remover on which hydrogen sulfide is adsorbed, can be recycled to be used.(AA) Adsorptive powder of hydrogen sulfide(BB) Concentration (mg/l)(CC) Time (min)COPYRIGHT KIPO 2014
