摘  要:
利用铁改性生物炭从富营养化水体中捕集磷,将其回用于农田,是高效利用生物质、促进磷资源高效利用的有效途径之一.然而,铁改性生物炭对磷的吸附效率受制备方式和水环境的影响极大.为促进富营养化水体磷的捕集效率和再利用,本文总结了国内外铁改性生物炭(Fe-B)的制备方法及其对水体中磷酸盐的吸附性能,阐述了Fe-B对磷的吸附机制,分析了pH值、共存离子、生物炭用量和温度对Fe-B吸附磷酸盐性能的影响,分析了富营养化水体中磷的农田资源化再利用潜力.本研究结果可为富营养化水体磷捕集与资源化再利用提供理论参考.

摘  要:
Using Fe-modified biochar(Fe-B)to capture phosphorus in eutrophic water and then reusing it as a phosphorus fertilizer for agricultural production is a sustainable way to remediate surface water eutrophication and develop agriculture.However,the adsorption efficiency of Fe-modified biochar is influenced by a variety of factors including methods to produce biochar and surface water environment.In this review,we analyze different methods to manufacture Fe-B and their efficacy for phosphate adsorption.Other factors we analyzed include pH value,coexisting ions,biochar application rate,temperature which have shown to affect the capacity of Fe-B to adsorb phosphorus.We also discuss the potential of Fe-B and the phosphorus it adsorbed to be reused as a slow-release phosphorus fertilizer for agricultural production,as well as the perspective of Fe-modified biochar(Fe-B)and its applications.
