中国城市污水处理工程污泥处置技术研究进展

Research progress on sludge treatment technology of urban sewage treatment project in China

随着我国城市化进程的发展,集中污水处理越来越普及,随之而来的是污泥产量的大幅增长。基于我国污泥处置现状,概述了稳定填埋、干化+焚烧+填埋、干化+土地利用、厌氧消化/好氧堆肥+土地利用、干化+热解、烧制+建筑材料等六种处置方法,并分析了各种处置技术的优缺点;最后展望了污泥资源化途径有待深入研究的方面,并提出建设性的意见。

As the development of urbanization in China,centralized sewage treatment is becoming popular.At the same time,the sludge production has increased substantially.According to the current status of sludge disposal in China,this review outlined six disposal methods,including stable landfill,desiccation+incineration+landfill,desicca-tion+land use,anaerobic digestion/aerobic composting+land use,desiccation+pyrolysis,fired+building materials and analyzed the advantages and disadvantages of each disposal technology.Furthermore,some constructive comments were suggested on sludge resource utilization.
