We examined different types of raw sewage sludge treatment, including consolidation, anaerobic mesophilic digestion with subsequent consolidation, and aerobic-thermophilic digestion. Of these, the most efficient reduction in infectious virus titer was achieved by mesophilic digestion with subsequent consolidation, although a pilot-scale aerobic-thermophilic digester was extremely time effective, producing sludges with similarly low virus titers in a small fraction of the time. Although none of the treatments examined consistently produced a sludge with undetectable virus levels, mesophilic digestion alone was found to be particularly unreliable in reducing the levels of infectious virus present in the raw sludge.
我们研究了不同类型的原生污水污泥处理方法，包括浓缩、随后进行浓缩的厌氧中温消化以及好氧高温消化。其中，通过随后进行浓缩的中温消化实现了传染性病毒滴度的最有效降低，尽管中试规模的好氧高温消化器极其节省时间，能在一小部分时间内产生病毒滴度同样低的污泥。虽然所研究的处理方法均未始终如一地产生病毒水平检测不到的污泥，但发现仅中温消化在降低原生污泥中存在的传染性病毒水平方面特别不可靠。
