摘要
生物质炭是生物质在缺氧条件下热解产生的富碳物质。因其具有孔隙结构发达、独特的表面性质和较强的吸附能力等特性,已成为有机废弃物好氧堆肥研究的热点。文章介绍了生物质炭的结构特点,综述了添加生物质炭对好氧堆肥的理化性质、有害气体排放、堆肥品质及重金属等方面的研究进展,着重讨论了堆肥过程中添加生物质炭对氮素持留的作用和可能的调控措施,并对今后生物质炭在堆肥系统中的应用进行了展望。
Biochar is a carbon-enriched material produced from biomassunder partial or complete exclusion of oxygen.Biochare has been paid more attention during the aerobic composting process because of well- developed structure,unique surface property and stronger absorption ability. This study introduced the structure characteristics of biochar,overviewed the impact of adding biochar on composting process including physicochemical property,noxious gas emission,compost quality and heavy metal content,summarized the effect of biochar on nitrogen transformation and the possible control measures in the composting process,and then discussed the application direction of biochar in compost system in the future.
