生物炭作为好氧堆肥添加剂的研究进展
Research progress on biochar as an additive for organic waste composting
摘要
Abstract
Composting and thermochemical conversion are effective ways to revalorize organic waste.Biochar is a carbon-rich material produced by thermochemical conversion with unique physicochemical properties.In recent years,the use of biochar as an additive for composting has become a hot research topic.Numerous scholars have discussed the effects of biochar on the composting process and the underlying mechanisms as well as the potential of co-composted biochar as soil amendment.The aim of this work is to evaluate the effectiveness of biochar as an additive for composting,to clarify the shortcomings of the current studies,and to propose future research directions.Current studies have shown that biochar as an additive for composting could improve the physicochemical properties of compost,enhance microbial activity,promote organic matter degradation and humification,reduce the emission of greenhouse gases and other gaseous pollutants,passivate heavy metals,and reduce the residual of organic pollutants.The performance of modified biochar is superior to pristine biochar.In the future,it is still necessary to analyze how the specific physicochemical properties of biochar(e.g.,particle size,pore structure,etc.)regulate the composting process at the micro-level.Co-composted biochar as soil amendment could improve soil health,but its effects on crop yield and quality are contingent on crop species and biochar rate.A direct comparison of co-composted biochar with biochar,compost,and biochar and compost co-application is still scarce.In addition,current studies are mostly short-term,therefore,the medium-term and long-term effects of co-composted biochar on soil health and crop production need to be further evaluated.关键词
