城市污泥处理过程中有机成分的变化

摘要

The organic ingredients should be focused on during treatment and disposal process of municipal sewage sludge, for sludge processing technical route selection is very important. Two kinds of domestic methods for sludge organic ingredients content measurement and organic ingredients classified research are introduced. Transformation of organic ingredients during treatment process of aerobic composting, anaerobic digestion, drying, incineration , hydrothermal treatment are elaborated,including the reaction mechanism of organic ingredients,organic ingredients composition and nature of the product.%有机成分是城市污泥处理处置中需要重点关注的对象,对于污泥处理技术路线的选择十分重要。介绍了我国城市污泥有机成分含量的2种测量方法和有机成分的分类研究,阐述了好氧堆肥、厌氧消化、干化、焚烧、水热处理等污泥处理过程中有机成分的变化,包括有机成分的反应机理,产物中有机成分的组成及性质等。
