摘要
随着污泥产量的逐年增加,污泥资源化受到了越来越多的关注,其中厌氧消化是当下应用最广泛的技术之一.目前,针对强化污泥厌氧消化效果的研究较多,而涉及污泥有机质对厌氧消化影响的机理研究仍在发展.本文从污泥中占比最高的有机质——蛋白质和多糖入手,讨论了其对厌氧消化过程的影响,并从成分和结构两个角度归纳了对蛋白质和多糖的主要解析技术,其中对于污泥中蛋白质与多糖高级结构的解析方法仍处于起步阶段,这也是限制污泥厌氧消化过程中有机质转化机制研究的因素之一,在未来需要更深入地探索.
With the growing amount of sludge,sludge resource recovery is getting more and more attention.Anaerobic digestion is one of the most common technologies for sludge treatment.Nowadays,research about the enhancement of sludge digestion keeps growing rapidly,while the research about the influence of organic matters in sludge on the anaerobic digestion mechanism is still developing.This review introduces the influence of dominating organic matters in sludge,protein and polysaccharide,on anaerobic digestion,and summarizes the main methods analyzing the content and structure of protein and polysaccharide in sludge.The analytical methods for advanced structure of protein and polysaccharide are still in its infancy,which become one of the limiting factors to study the mechanism of organic matter transformation during anaerobic digestion,and require further exploration in future.
