摘　　要：随着我国经济的发展,城镇污水处理厂污泥量不断增多,污泥的处理处置以及资源化利用成为当前亟需解决的问题。在对污泥资源化方式进行概述和分类的基础上,从发展历程、应用现状、地域特征等方面对不同污泥处置技术进行对比研究,系统探讨和分析了我国各种污泥资源化处置技术的特点及不足。分析认为,我国污泥资源化处置技术投产项目呈显著上升趋势,同时,各地区由于经济发展的不平衡,呈现东多西少的格局,而浙江、江苏、山东三省远高于其他省份。最后针对我国污泥资源化处置的发展方向提出了建议,以期对污泥资源化的发展有所裨益。With the economic development in China,the amount of urban sewage sludge in the sewage treatment plants is growing significantly,and therefore the treatment,disposal,and resource utilization of the sewage sludge become an urgent problem.In this paper,the ways for resource utilization of the sewage sludge were introduced and classified,and different treatment technologies for the sewage sludge were compared from the aspects of development,current application situation,and regional characteristics.Then,the features and shortages of different treatment technologies for treatment and resource utilization of the sewage sludge in China were discussed and analyzed.The results showed that the projects put into use for the treatment and resource utilization of the sewage sludge in China are increasing.However,due to the uneven economic development in China,the eastern part has more projects than the western part,especially Zhejiang,Jiangsu,and Shandong provinces.Finally,the suggestions for the development of the treatment and resource utilization of the sewage sludge were proposed.
