本文讨论了在大型沼气厂中处理奶牛粪便的卫生设施的卫生优势。浆液样品采集自日本北海道的两个高温沼气厂（55°C）和两个中温沼气厂（38°C）。在两个嗜热沼气厂中，厌氧消化 (AD) 后的浆液中均未发现可检测到的产气大肠杆菌和肠球菌数量。然而，在两个中温沼气厂中，即使在厌氧消化后，在浆液中也检测到了大肠杆菌和肠球菌的活数量。在嗜温消化过程中，浆液中产气大肠杆菌和肠球菌的平均减少时间（T90）值分别为 13.3 天和 16.7 天。
The paper deals with the hygienic advantages of sanitation to treat dairy manure in full‐scale biogas plants. The slurry samples were collected from two thermophilic biogas plants (55°C) and two mesophilic biogas plants (38°C) in Hokkaido Japan. A detectable number ofColi‐aerogenesgroup andEnterococcusin the slurries after anaerobic digestion (AD) could not be found in either thermophilic biogas plants. However, in both mesophilic biogas plants the viable numbers ofColi‐aerogenesgroup andEnterococcuswere detected in the slurries even after anaerobic digestion. The mean decimation reduction time (T90) values of theColi‐aerogenesgroup andEnterococcusin the slurries during mesophilic digestion were 13.3 days and 16.7 days, respectively.
