摘要:

沼渣是生物质经厌氧消化后产生的固体残渣,也是具有较大应用潜力的二次资源。与填埋、焚烧等传统沼渣处理工艺相比,使用热化学法处理废弃生物质沼渣可更好地实现沼渣中有机物的固定,且制备得到的沼渣生物炭结构稳定、性能优良,能被广泛应用于污染物吸附、催化降解、土壤修复等诸多领域。本文归纳总结了国内外常见的沼渣生物炭制备技术和改性方法,重点介绍了沼渣生物炭的结构、元素组成和理化性质。同时,汇总了现阶段沼渣生物炭的主要资源化应用途径,并对未来沼渣生物炭资源利用的发展方向进行了展望。

Abstract:

Biogas residue was a solid residue produced by anaerobic fermentation of biomass, which was also a secondary resource with great application potential. Compared with the traditional biogas residue treatment process such as landfill and incineration, the use of thermochemical method to treat waste biomass biogas residue could achieve the fixation of organic matter in the biogas residue, and the prepared biogas residue biochar had stable structure and excellent performance, which could be widely used in pollutant adsorption, catalytic degradation, soil remediation and many other fields. This paper summarized the common preparation technologies and modification methods of biogas residue biochar at home and abroad, and focused on the structure, elemental composition and physical and chemical properties of biogas residue biochar. At the same time, the main resource application ways of biogas residue biochar were summarized, and the development direction of biogas residue biochar resource utilization in the future was prospected.

Key words: biogas slag, biomass, waste treatment, adsorbents, catalyst
