摘要
目前,我国大约51.9%的生活垃圾采用填埋处理方式,填埋场占据大量的土地资源,同时也是周边环境的重要污染源。探究垃圾填埋场生化腐殖质的形成机制及其影响因素,可以加速垃圾填埋场腐殖化进程,减少腐殖化时间,同时也降低了腐殖化过程中产生的污染物。本文综述了垃圾填埋场腐殖质形成机制、腐殖质氧化还原机理及其能力、腐殖质形成来源物质的降解机制、无机矿物与微生物耦合促进腐殖质形成机制。发现目前对于垃圾填埋场实际情况下木质纤维素降解关键微生物以及功能酶的研究、无机矿物与微生物耦合促进腐殖质形成机制研究几乎为空白。确定垃圾填埋场木质纤维素降解的关键微生物和功能酶以及揭示无机矿物与微生物耦合促进腐殖质形成机制对于开发垃圾填埋场快速稳定技术具有重要意义。
At present,about 51.9%of domestic waste is treated by landfill that taken up a large amount of soil resources and been major source of pollution for the surroundings in China.Uderstanding the formation mechanism of biochemical humic substance in landfills and its impact factors could be helpful for clarifying the humification process of landfills to reduce the humification time and the pollutants during the process.The formation mechanism of humic substance in landfills,the redox mechanism and ability of humic substance,degradation mechanism of humic substances forming source material,and the mechanism of coupling inorganic minerals and microorganisms to promote humic substance formation were discussed in this paper.The key microorganisms and functional enzymes for lignocellulose degradation in actual landfills,and the mechanism coupling inorganic minerals and microorganisms to promote the formation of humic substance are still limited.It is necessary to develop rapid landfill stabilization technologies based on identifying key microorganisms and functional enzymes for lignocellulose degradation in landfills and revealing the mechanism of coupling inorganic mineral and microorganisms for humic substance formation.
