Abstract

application/pdf<br />The paper deals with the hygienic advantages of sanitation to treat dairy manure in full-scale biogas plants. Slurry samples were collected from two thermophilic biogas plants (55ºC) and two mesophilic biogas plants (38ºC) in Hokkaido, Japan. The detectable number of Coli-aerogenes group and Enterococcus in the slurries after anaerobic digestion could not be found in both thermophilic biogas plants. In both mesophilic biogas plants, however, the viable numbers of Coli-aerogenes group and Enterococcus were detected in the slurries even after anaerobic digestion. The mean decimation reduction time (T90) values of Coli-aerogenes group and Enterococcus in the slurries during mesophilic digestion were 13.3 d and 16.7 d, respectively.<br />2009年帯広農村開発教育国際セミナーシンポジウム「農畜産物生産と地球環境に関する持続的開発のための教育」報告書
