随着经济的发展、居民生活水平日渐提高,生活质量越来越好,这导致人们产生的生物质垃圾日渐增多,生物质垃圾对环境的污染已经成为日益严重的问题。我国现阶段垃圾回收方式主要是以下两种:一种是社区聘有专门从事垃圾回收的环保工人,二是以盈利为目的小商贩式回收。这两种回收方式不仅人力物力耗费太多,而且对于环境保护没有起到太大作用。究其原因就是因为人们没有对垃圾进行科学的系统的分类,没有将垃圾资源充分利用。生物质垃圾堆肥与沼气生成技术将大量生物质垃圾充分利用起来实现了资源回收利用与节能环保。技术介绍主要分为堆肥技术介绍和沼气化技术介绍,堆肥技术包含好氧堆肥技术和厌氧堆肥技术,沼气化技术除了传统的沼气池技术外还有垃圾填埋制沼技术。通过对生物质垃圾堆肥与沼气技术的可行性评价,得出该工艺技术切实可行。
With the development of economy, the living standards of residents are getting higher and higher and the quality of life is getting better and better. As a result, people produce more and more biomass wastes and the environmental pollution caused by biomass wastes has become an increasingly serious problem. At present, China’s garbage collection methods are mainly the following two kinds: one is engaged by the community specializing in garbage recycling environmental workers, and second, for the purpose of profit small trader recycling. These two recovery methods not only cost too much manpower and resources, but also do not play a significant role in environmental protection. The reason is because people do not have a systematic and systematic classification of rubbish, and do not make full use of rubbish resources. Biomass waste composting and biogas generation technologies will make full use of a large amount of biomass waste to achieve resource recycling and energy conservation and environmental protection. The introduction of technology is mainly divided into introduction of composting technology and biogasification technology. Composting technology includes aerobic composting technology and anaerobic composting technology. Biogasification technology includes landfill biogas technology in addition to traditional biogas digester technology. Through the feasibility evaluation of biomass waste composting and biogas technology, it is concluded that the technology is feasible.
