摘　　要：沼液作为可回收利用的农业废弃物资源,其中含有丰富的磷素资源,从沼液中进行磷素等养分的回收不仅具有净化水质的作用,还能实现磷素等养分的回收利用;生物炭具有表面积大且含有丰富的官能团和大量碱性物质和多孔性等独特性质,作为一种新兴的环保型吸附材料用于沼液中磷素的吸附与解吸,且已被广泛应用于环境污染治理。为同类研究及沼液的资源化利用提供参考,介绍了沼液的利用与危害,从生物炭吸附磷的作用机制及其不同影响因素等方面概述了利用生物炭回收沼液中磷素营养的研究进展,对未来研究方向进行了展望。As a recyclable agricultural waste resource,biogas slurry contains abundant phosphorus.Recycling phosphorus and other nutrients from biogas slurry can not only purify water quality,but also realize the recycle and utilization of phosphorus.Biochar has the unique features of great surface area,containing abundant functional group,large amount of alkaline substance and porosity,which is used as a new environmental friendly adsorption material to adsorb and desorb phosphorus in biogas slurry.It has been widely used in management of environment pollution.In order to provide a reference for resource utilization of biogas slurry and similar research,the utilization and hazard of biogas slurry is introduced,the research progress on biochar recycling phosphorus from biogas slurry is reviewed from the effect mechanism and different influencing factors of biochar adsorbing phosphorus,and the future research direction is prospected as well.
