有机废弃物处置不当引起的环境污染与潜在资源浪费已引起广泛关注,生物堆肥处理是解决有机废弃物污染与再利用的主要技术手段之一.蚯蚓堆肥和蝇蛆生物转化是废弃物生物处理与利用的两项代表性技术,不仅可将废弃物基质转化为均匀且稳定的类腐殖质化合物,同时收获丰富的虫体蛋白.本文在介绍蚯蚓堆肥和蝇蛆生物转化基本定义与原理的基础上,重点综述了两种技术的工艺过程与机制、影响因素与控制、以及废弃物生物质特性演变规律等;进而阐述了虫体生物量转化、肠道消化分解、生物酶降解、以及微生物区系等多重物理及生化机制共同实现有机废弃物减量化-增值化-稳定化处理的共性与差异,以及工程应用潜力与发展前景.
There is a growing attention on the environmental pollution and loss of potential regeneration of resources due to the poor handling of organic wastes,while earthworm vermicomposting and larvae bioconversion are well-known as two promising bio-technologies for sustainable wastes treatments,where earthworms or housefly larvae are employed to convert the organic wastes into humus like material,together with value-added worm product.Taken earthworm(Eisenia foetida) and housefly larvae(Musca domestica) as model species,this work illustrates fundamental definition and principle,operational process,technical mechanism,main factors,and bio-chemical features of organisms of these two technologies.Integrated with the physical and biochemical mechanisms,processes of biomass conversion,intestinal digestion,enzyme degradation and microflora decomposition are comprehensively reviewed on waste treatments with purposes of waste reduction,value-addition,and stabilization.
