堆肥过程中腐殖酸的生成演化及应用研究进展

Formation and evolution of humic acid during composting process and its application

腐殖酸是堆肥过程中生成的最具代表性的次生产物,对堆肥的稳定性、腐熟度等性质有重要影响。介绍了堆肥过程中腐殖酸的生成及动态变化,分析了堆肥腐殖酸的结构特性,归纳了堆肥过程中腐殖酸生成机制,并在此基础上探讨了影响堆肥腐殖酸生成演化的主要影响因素,总结了堆肥腐殖酸作为堆肥腐熟度指标、表面活性物质、吸附剂等的应用情况,最后提出了当前堆肥腐殖酸研究中存在的主要问题,并对未来的研究方向进行了展望。

Humic acids （HA）are the most representative secondary products of composting which has significant effect on the properties of compost. Base on the comprehensive literature review, this paper summarized the formation and dynamic change of HA during the composting process,introduced structural evolution of HA and methods that widely used for HA detection. The influencing factors of HA formation were characterized and the application of HA based on its maturity indicating, surfactant and adsorption properties were introduced. Finally, the existing problems in HA research were discussed and additional researches that could benefit HA application were proposed.
