循环流化床污泥焚烧一体化工艺的研究与应用

采用焚烧技术处理污泥,并最大限度地利用污泥中的能量,可以彻底实现污泥的无害化、减量化以及资源化。在此提出一种循环流化床污泥无害化焚烧一体化技术工艺,可以实现含水率75%的污泥不添加辅助燃料,能量实现自持平衡,以350t/d污泥处理工程为例,介绍工艺的主要流程特点以及技术经济性分析。

STUDY ON APPLICATION OF INTEGRATED PROCESS OF SEWAGE SLUDGE ON CIRCULATING FLUIDIZED BED INCINERATION

The volume of sewage sludge can be reduced and will become harmless, whose energy can be utilized by incineration of sewage sludge.In this paper,the integrated process of sewage sludge on circulating fluidized bed incineration is presented.The self-sustaining energy balance can be realized as the water fraction of sewage sludge is not more than 75%.The 350 t/d treatment capacity of sewage sludge is taken as an example for analysis.The process characteristic and techno-economy are presented.
