摘要

摘要: 针对好氧颗粒污泥培养速度慢、启动周期长等突出问题,通过综述好氧颗粒污泥的形成机理、颗粒化主要影响参数以及促进颗粒化的方法,发现调整反应器的水力剪切力、沉降时间、有机负荷、饥饿期等参数有利于诱导微生物分泌更多的胞外聚合物(EPS),促进初期微生物聚集体的快速形成,从而缩短好氧颗粒化时间。因此,当前快速颗粒化的方法基本上是基于诱导初期颗粒聚集体快速形成或直接投加聚集体的方法缩短好氧颗粒化时。最后,总结好氧颗粒快速培养过程中存在问题,并提出好氧颗粒污泥形成机理的明晰、好氧颗粒化的标准以及培养指标体系的建立是解决相关问题的关键,以及今后的研究重点。

Abstract: In order to solve the problem of long start-up period of the aerobic granular sludge system, the paper reviewed the forming mechanism, the main affecting factors and the methods to promote aerobic granulation. It was found that inducing microbes to secrete more extracellular polymer (EPS) could promote the rapid formation of initial microbial aggregates, and thus decreased the aerobic granulation time by adjusting the parameters of hydraulic shear force, settling time, organic load and starvation stage of the reactors. Therefore, the current measures of rapid granulation was essentially based on the method of inducing the rapidly forming initial microbe aggregates or directly adding aggregates, to realize the shortening of the time for aerobic granulation. Finally, this paper pointed out the problems existing in the rapid cultivation of aerobic granule, and the key to solve the related problems, and the future research focus is to clarify the formation mechanism of aerobic granule sludge, establish the standard of aerobic granulation and the cultivation indexes system.
