厌氧消化外源添加剂研究进展

RESEARCH PROGRESS ON EXOGENOUS ADDITIVES FOR ANAEROBIC DIGESTION

向厌氧消化系统中引入外源添加剂可提高厌氧消化系统性能,在快速启动、降低抑制作用、提高发酵效率、改善过程稳定性等方面发挥积极作用。近年来,有关厌氧消化添加剂的研究得到了迅速发展。综述了8类厌氧消化添加剂(微生物、酶、微量元素、纳米材料、吸附剂、导电材料、灰分和气体)的研究进展,重点讨论其在厌氧消化中的作用效果及作用机理,图像化呈现了各类添加剂在厌氧系统中的作用方式,讨论了添加剂使用需要关注的关键问题,并指明了目前的研究不足和未来的研究方向,旨在为厌氧消化添加剂的深入研究和应用提供重要参考。

Introducing exogenous additives into the anaerobic digestion system can improve the performance of the anaerobic digestion system and play a positive role in rapid start-up,reducing inhibition,improving fermentation efficiency,and improving process stability.In recent years,research on anaerobic digestion additives has developed rapidly.This paper reviews the research progress of eight kinds of anaerobic digestion additives(microorganisms,enzymes,trace elements,nanomaterials,adsorbents,conductive materials,ash,and gas).It focuses on discussing their effects and mechanisms in anaerobic digestion.This paper graphically presents the action modes of various additives in the anaerobic system,discusses the fundamental problems that need to be paid attention to in the use of additives,and points out the current research deficiencies and future research directions,aiming at providing essential references for the in-depth research and application of anaerobic digestion additives.
