摘　　要：厨余垃圾堆肥是厨余垃圾资源化处理处置的重要途径之一。通过构建厨余垃圾好氧堆肥和堆肥精筛工程化工艺,分析了厨余垃圾堆肥的减量化效果,评价了厨余垃圾堆肥产品的质量性质。结果表明:厨余垃圾堆肥具有良好的减量化效果,平均减量化率为69.2%;堆肥产品(<6 mm)的有机质质量分数、总养分质量分数和种子发芽指数分别为47.8%,7.9%和71.2%,均优于NY/T 525—2021《有机肥料》标准。研究结果可为厨余垃圾资源化利用及处理处置提供技术参考。Composting kitchen waste is an important way to treat and dispose of kitchen waste as a resource.In this study,the reduction effect of kitchen waste composting was analyzed by constructing the aerobic composting and fine screening engineering process,and the quality characteristics of kitchen waste composting products were evaluated.The results showed that the kitchen waste compost had a good reduction effect,and the average reduction rate was 69.2%.The organic matter mass fraction,total nutrient mass fraction,and seed germination index of compost products(<6 mm)were 47.8%,7.9%and 71.2%,respectively,which were superior to the standard of Organic Fertilizer(NY/T 525-2021).The results of this study could provide a technical reference for resource utilization and the treatment of kitchen waste.
