Abstract
Anaerobically digested sludge contains an agent that causes irreversible inactivation of poliovirus. It has now been shown that the agent responsible for this activity is ammonia. The effect of ammonia on poliovirus appears to be typical for picornaviruses, but reovirus, an enteric virus of another group, is quite resistant to this compound. Because ammonia is not virucidal in its charged state, it expresses significant activity only at pH values greater than 8. Therefore, increasing the pH of sludge should cause rapid inactivation of indigenous picornaviruses.
摘要
厌氧消化污泥中含有一种可导致脊髓灰质炎病毒不可逆失活的物质。现已证明，造成这种活性的物质是氨。氨对脊髓灰质炎病毒的影响似乎是小核糖核酸病毒的典型情况，但呼肠孤病毒，另一类肠道病毒，对这种化合物相当耐受。由于氨在其带电状态下没有杀病毒作用，它仅在pH值大于8时才表现出显著活性。因此，提高污泥的pH值应会导致本地小核糖核酸病毒迅速失活。
