分级分相厌氧消化工艺的研究现状

摘要

厌氧消化是污泥处理的主要途径之一,分级分相厌氧消化工艺因产酸相和产甲烷相的分离而具有一系列的特点和优势.从污泥的停留时间、TOCD的去除率、COD去除率、应用范围等多角度对分级分相厌氧消化工艺进行了系统的分析.对最新的研究成果进行了总结,并对其在未来污泥处理中的应用前景进行了讨论.%As one of the main methods of activated sludge treatment, the staged multiphase anaerobic digestion has several characteristics and advantages due to the separation of its acidogenic and methanogenic phases. A systematic analysis was made on the hydraulic retention time, TOCD removal rate,COD removal rate and application scope of the staged multiphase anaerobic digestion technique. The latest researches were summarized in this paper and its application prospect in sludge treatment was discussed.
