农村多源有机固体废弃物协同好氧堆肥技术研究进展OA

The rapid increase of multi-source rural organic solid waste,coupled with disorderly disposal and inefficient treatment,has become a major constraint on rural environmental improvement.Aerobic composting is recognized as an important recycling pathway due to its simplicity and agricultural applicability.However,traditional composting relies on monotonous feedstocks,often resulting in low degradation efficiency and severe nutrient losses.Synergistic co-composting,by integrating physicochemical complementarity of materials with microbial functional interactions,can markedly enhance organic matter degradation and humification while mitigating environmental risks.This review summarizes the sources and characteristics of typical wastes,recent advances in co-composting regarding feedstock formulation,process regulation,and microbial-driven transformations,and elucidates its mechanisms in carbon-nitrogen cycling,lignin degradation,and resistance gene reduction.It further identifies current bottlenecks in raw material heterogeneity,collection and pretreatment,process equipment,pollution control,and management frameworks,and proposes future directions in scientific material matching,process optimization,equipment innovation,standard refinement,and intelligent management.
