摘要

摘要: 厌氧消化是一种可实现有机固废资源化的生物处理技术，目前主要存在产酸、产甲烷效率低下等问题。研究表明：零价铁（Fe⁰）的添加可有效提升有机固废厌氧消化性能。从Fe⁰对有机固废产酸、产甲烷效率的影响，以及Fe⁰与其他添加剂联合运用的效果等方面，综述Fe⁰在有机固废厌氧消化过程中的应用。Fe⁰对有机固废厌氧消化性能影响的作用机制主要包括降低系统氧化还原电位，腐蚀析氢作用，影响微生物群落，影响关键酶活性。此外，以硫化物、抗生素抗性基因（antibiotic resistance genes，ARGs）为例，阐述了Fe⁰对有机固废厌氧消化过程中污染物的去除作用。指出Fe⁰在有机固废厌氧消化应用过程中存在的问题及挑战，并对未来Fe⁰在有机固废厌氧消化过程中的深入研究问题做出了展望。

Abstract: Anaerobic digestion is a kind of biological treatment technology that can realize the recycling of organic solid waste. But there are main problems such as low efficiency of acid production and methane production at present. Studies showed that the addition of zero valent iron (Fe⁰) could effectively improve the anaerobic digestion performance of organic solid waste. This article reviewed the application of Fe⁰ in the process of anaerobic digestion of organic solid waste from the aspects of the effect of Fe⁰ on the acid production, methane production efficiency of organic solid waste, the combined effect of Fe⁰ and other additives. The mechanism of effect of Fe⁰ on the anaerobic digestion performance of organic solid waste mainly included reducing the system redox potential, corrosive hydrogen evolution, affecting the microbial community, affecting the activity of key enzymes. In addition, taking sulfide and antibiotic resistance genes (ARGs) as an example, the effect of Fe⁰ on removal of pollutants in the process of anaerobic digestion of organic solid waste was described. There are many deficiencies and challenges in the application of Fe⁰ in the anaerobic digestion of organic solid. The future application of Fe⁰ in the anaerobic digestion of organic solid waste was prospected from multiple perspectives.
