摘　　要：本文旨在探究在不同处理模式下园林废弃物的无害化处理效果,为园林废弃物的无害化处理及资源化利用提供有效途径。堆体设置CK(园林废弃物)、T1(园林废弃物+尿素+红糖+有机肥腐熟剂)、T2(园林废弃物+尿素+红糖+园林废弃物降解复合菌剂+稻糠粉)的三种处理。在好氧发酵过程中,通过对温度、碳氮比、发芽率、发芽指数、重金属含量、杂草种子灭活等参数测定。发现T2处理通过高温好氧发酵,对病原菌、杂草种子等进行了较为彻底的无害化处理,发酵后的产物在完成腐熟过程后已经实现了无害化的标准,这一成果为园林废弃物进行无害化处理及其资源化利用提供了一种参考性的依据。This study aims to investigate the harmless treatment efficiency of garden waste under different processing modes,providing effective approaches for its safe disposal and resource utilization.Three treatments were established:CK(garden waste only),T1(garden waste+urea+brown sugar+organic fertilizer decomposing agent),and T2(garden waste+urea+brown sugar+composite microbial inoculum for garden waste degradation+rice bran powder).During aerobic fermentation,parameters including temperature,carbon-to-nitrogen ratio,germination rate,germination index,heavy metal content,and weed seed inactivation were measured.Results demonstrated that T2 treatment achieved thorough harmless treatment of pathogens and weed seeds through high-temperature aerobic fermentation.The fermented product met harmless treatment standards after complete maturation,providing a referential basis for safe disposal and resource utilization of garden waste.
