蚯蚓堆肥技术在固体废弃物处理中的研究进展OA

Vermicomposting represents a green and energy-efficient biotechnology for organic solid waste treatment,enabling waste reduction,detoxification,and resource recovery via the synergistic degradation by earthworms and microorganisms.This study systematically elucidated the fundamental principles of vermicomposting and its technical superiority over conventional treatment technologies in terms of environmental compatibility,product safety,and greenhouse gas mitigation.A comprehensive review was presented on the performance of vermicomposting in treating diverse organic solid wastes,including livestock manure,crop straw,municipal organic waste,and sewage sludge,with particular emphasis on pretreatment requirements,treatment duration,and key challenges specific to each waste type.The resource utilization value of vermicompost was summarized,covering its roles in enhancing soil fertility,suppressing phytopathogens,remediating heavy metal-contaminated soils,and enabling high-value applications.Furthermore,this review identified the major technical bottlenecks currently limiting the widespread adoption of vermicomposting,including relatively low treatment efficiency,insufficient scalability,high sensitivity to ambient conditions,and residual contaminants such as heavy metals.Finally,future research directions are proposed to provide a systematic reference for advancing the engineering application and industrial deployment of vermicomposting technology.
