城市生物质废物厌氧消化处理可行性分析

Feasibility Analysis of Treating and Recycling Municipal Biomass Waste Using Anaerobic Digestion

城市废物传统的处理方式主要包括卫生填埋、焚烧和堆肥,而近年来,随着城市生活垃圾中生物质废物的增加以及世界能源短缺现象的加剧,具有废物处理和资源回收双重效益的生物质废物厌氧消化技术日益受到世界各国的广泛关注。文章分析了我国城市生物质废物的种类和性质,指出了采用目前的三种传统废物处理方式处理我国城市生物质废物的弊端,并提出了利用厌氧消化技术处理城市生物质废物的适用性,对比分析了上述四种废物处理方式的优缺点,并从政策方向性、技术工艺可靠性、原料和市场稳定性,以及环境、经济和社会效益优良性等多方面对城市生物质废物厌氧消化技术的可行性进行了分析,说明厌氧消化技术必将成为未来生物质废物资源化处理的发展趋势。

There are many traditional municipal solid waste treatment technologies including sanitary landfill,incineration and compost,however,anaerobic digestion is getting more and more attention in recent years since it can both treat waste and recycle resource with the increase of organic content in municipal solid waste and aggravation of energy shortage in the world. Kinds,characters and treatment methods of municipal solid waste and its disadvantages were analyzed,applicability of anaerobic digestion technology for municipal solid waste was proposed. With analysis of advantages and disadvantages,feasibility of treating and recycling municipal biomass waste using anaerobic digestion was analyzed from the perspectives of policy,technology maturation,stability of raw materials,market as well as environmental,economic and social benefits. Anaerobic digestion technology would be a trend of municipal biomass waste treatment in future.
