효소복합체가 양돈슬러리 및 돈사 악취발생에 미치는 영향

Abstract

This study was carried out to investigate the effect of enzyme complex on odor emission from swine slurry and the process of making swine liquid manure. Ammonia and hydrogen sulfide concentrations were significantly decreased by using the enzyme complex of liter per ton level of liquid swine slurry in the manure storage tank according to the time. Characteristics of liquid swine slurry were affected by the enzyme complex, total nitrogen and ammonia nitrogen contents were reduced compare with control. Ammonia and hydrogen sulfide concentrations in the finishing pig building and offensive odor compound on the boundary line of swine farm were significantly decreased by spraying in swine finishing building. In conclusion, the results obtained from this study suggest that using the enzyme complex of liter per ton level of liquid swine slurry for making liquid swine manure may improve the quality of swine liquid fertilizer and reduce odor emission. Also farm scale enzyme complex treatment may improve air quality in finishing pig building and deduce offensive odor compound of swine farm.
