3N양돈분뇨 정화공법에서의 공정개선에 의한 악취 저감방안 연구
Abstract
This study pointed out problems on the operation by estimating process efficiency to the 3N-system(quick fermentable treatment process) which occupy plant to treat swine wastewater more than about 30 % in Jeju. And the parts to improve from problems were deduced and introduced those in situ. When the parts to improve from problems were not introduced, the Concentration of H₂S and NH₄ was 5 and 50ppm in the fermenter, respectively. But the concentration of H₂S and NH₃ was shown N.D. and 1~2 ppm in the fermenter after introduction. The concentration of H₂S and NH₃ were measured by 16 and 300 ppm highly in the aeratin tank before improvement, but those were shown N.D. and 0~1 ppm after improvement, respectively. Therefore, it showed possibility which could decrease odor efficiently with low cost by this study in 3N-system.
