In a 22-month study, viruses were detected in 84% (62/74) of raw, 53% (19/36) of anaerobically digested, and 39% (11/28) of lagoon-dried sludge samples. Lagoon sludge contained detectable viruses (reovirus and enterovirus groups) even after 8 months of retention. Because of such prolonged virus survival in sludge, care must be taken in its disposal or utilization.
在一项为期22个月的研究中,在84%(62/74)的原生污泥、53%(19/36)的厌氧消化污泥和39%(11/28)的泻湖干化污泥样本中检测到病毒。即使在泻湖污泥留存8个月后,仍含有可检测到的病毒(呼肠孤病毒和肠道病毒组)。由于病毒在污泥中存活时间如此之长,因此在污泥的处置或利用过程中必须格外小心。
