摘要 采用中温(35℃)两相厌氧消化工艺处理初沉污泥与剩余污泥的混合样(1∶1),以实现污泥的稳定化。结果表明,在水力停留时间约为10 d、有机负荷为2.75 kgVS/(m^3·d)时,对TCOD的去除率可达46%,对VS的去除率为41%;产甲烷相反应器的最大比产甲烷活性为0.19LCH4/(gVS·d),并保持相对稳定;两相反应器内污泥的比脱氢酶活性都出现了增长,并维持在25~32μgINTF/(mgVS·h)之间;经消化后污泥的沉降性和脱水性变差。 The mesophilic(35 ℃) two-phase anaerobic digestion(TPAD) process was used to treat mixed sludge from primary sedimentation and secondary sedimentation tanks(1 ∶1) to realize sludge stabilization.The results show that when HRT is about 10 days and organic loading rate is 2.75 kgVS/(m^3·d),the removal rates of TCOD and VS are 46% and 41% respectively.The maximal specific methanogenic activity(SMA) of methanogenic phase reactor is 0.19 LCH4/(gVS·d) and keeps stable.The specific dehydrogenase activity(INT-DHA) of sludge in the two-phase reactor is increased,maintaining within the range of 25 to 32 μgINTF/(mgVS·h).The settleability and dewaterability of sludge become poorer after the digestion.
