The electro-Fenton (EF) disintegration using iron electrodes was performed for the pretreatment of waste activated sludge (WAS). The effect of this electro-chemical pretreatment on anaerobic digestion (AD) performance and microbial population structure was studied. An improvement of biodegradability and bioaccessibility of organic matter was demonstrated. AD of pretreated WAS in an up-flow anaerobic sludge blanket reactor (UASB) resulted to an increase of biogas production by 60 % compared to control reactor without disintegration. PCR-DGGE and real-time qPCR analyses showed that the high abundance of bacteria and the coexistence of Coprothermobacter in the UASB digestate fed with disintegrated sample established a stable bacterial association which is in line with the AD performance. Besides, the increased number of methanogens along the process allowed the improvement of methane production in comparison to control reactor.

使用铁电极进行电芬顿（EF）分解用于废活性污泥（WAS）的预处理。研究了这种电化学预处理对厌氧消化 (AD) 性能和微生物种群结构的影响。证明了有机物质的生物降解性和生物可及性的改进。与未分解的对照反应器相比，在上流式厌氧污泥层反应器 (UASB) 中预处理 WAS 的 AD 导致沼气产量增加 60%。PCR-DGGE 和实时 qPCR 分析表明，在用崩解样品喂养的 UASB 消化物中细菌的高丰度和 Coprothermobacter 的共存建立了稳定的细菌关联，这与 AD 性能一致。除了，
