摘要
厌氧消化是目前国际上常用的污泥生物处理方法,但是传统污泥厌氧消化法存在有机质厌氧转化率低、停留时间长、产气率较低等问题,限制了其应用。文章在分析剩余污泥处理现状的基础上,介绍了预处理技术,投加生物酶促进剂,微生物菌种技术,多种技术耦合,混合基质共消化,分级分相厌氧消化等厌氧消化强化技术类型及其处理效果,以及技术发展趋势,为后续研究提供参考。
Anaerobic digestion is the commonly used biological treatment for excess sludge in the world. However,the traditional method has the problems of low conversion rate of organic matter,long residence time and low gas production rate,which have limited its application. Based on the analysis of the excess sludge treatment status,this paper introduced the pretreatment technology,bio-enzyme promoter techniques,microbial techniques,coupling of different techniques,mixed co-digestions,phase separated anaerobic digestions,and etc. And the trend of these technology development were discussed,providing reference for the follow-up research.
