摘要 厌氧消化技术是污泥稳定化和资源化处理的常用技术,能够实现有机物的减量化、无害化,还能回收宝贵的能源物质—甲烷。随着城市化进程加快及城市污水处理量增加,污泥产量也在大幅增加,同时,面临全球性的能源危机以及国家环保法规的相继出台,厌氧消化将具有更广阔的应用前景。主要从预处理方法、宏介体投加及微生物群落结构3个方面,概述了厌氧消化技术目前研究现状,并分析了不同的预处理方法及宏介体投加对厌氧消化过程的影响。

Abstract :Anaerobic digestion technology is the most prevalent for sludge stabilization and resource treatment, which can realize the reduction and innocuity of organic matter, and recover valuable energy substance--methane. With the acceleration of urbanization and the increase of municipal sewage treatment capacity, sludge production is also increasing significantly. Meanwhile, in the face of global energy crisis and the introduction of national environmental protection laws and regulations, anaerobic digestion will have a broader application prospect. The present research status of anaerobic digestion technology was summarized from three aspects, pretreatment method, macro copula dosage and microbial community structure, the effects of different pretreatment methods and macro copula dosing on anaerobic digestion were analyzed.
