堆肥腐殖化:非生物学与生物学调控机制概述

Compost Humification:An Overview of Abiotic and Biological Regulatory Mechanisms

堆肥技术是有机固体废弃物处理处置与资源化利用最有效手段之一,涉及诸多复杂的非生物学与生物学反应。本文分别从非生物学及生物学层面阐述了腐殖化进程调控机制。非生物学腐殖酸合成机制涵盖了木质素-蛋白理论、多酚自缩合、多酚-蛋白途径以及美拉德反应。生物学途径包含堆肥进程碳组分的固定、木质纤维素的生物转化、反硝化进程等对腐殖化进程的响应。旨在为堆肥腐殖化进程中腐殖质的合成提供更为全面的技术参考和现状概述。

Composting technology is one of the most effective organic solid waste treatment and disposal and resource utilization,involving many complex non-biological and biological reactions.In this paper,the formation and regulation mechanisms of the humification process are described at the non-biological and biological levels,respectively.The non-biological humic acid synthesis mechanisms include the lignin-protein theory,polyphenol self-condensation,the polyphenol-protein pathway,and the Maillard reaction.Biological pathways include the fixation of carbon fractions,the biotransformation of lignocellulose,denitrification,and other responses to the composting humification process.The aim is to provide a more comprehensive technical reference and overview of the current status of humus synthesis in the compost humification process.
