蚯蚓在固体废物处理中的应用

Technology of Vermicomposting for Treating Organic Waste

蚯蚓在陆地生态系统中,对有机物的循环、维持生态系统平衡起着重要的作用,蚯蚓堆肥技术是利用蚯蚓与微生物的作用将废弃的有机物转化为有益的腐殖质。作者介绍了蚯蚓堆肥与普通堆肥的区别及蚯蚓堆肥的成份。在有机废物处理中,用蚯蚓堆肥可处理城市生活垃圾、污水厂污泥、造纸厂污泥、禽畜粪及农业废弃物等。堆肥产物可作为土壤改良剂、优质肥料等,分离出来的蚯蚓可作饲料。因此蚯蚓堆肥将废弃的有机物转化为有益的肥料,达到了污染物减量化、资源化、无害化的目标,具有社会的、经济的、环境的意义。

Earthworms play a great role in recycling of organics and system balance in natural land ecosystem. Vermicomposting transform the organic waste to available manure by interaction of microorganisms and earthworms.This paper discusses the difference between common composting and vermicomposting, Vermicomposting can be used to treat organic waste,such as municipal rubbish, sewage and papermill sludge, feces of animals and waste materials during agriculture.The end product can be used as soil organic amendment and better fertilizer,The earthworm can be used as feedstuff for animal or fish.The process of vermicomposting produces better quality manure with reducing,resource and no-harm of waste and is of social,economic and environmental significance.
