摘要
近年来,因水体中氮磷化合物含量不断的增加进而出现了水体富营养化现象,水体质量的降低对整个生态系统产生了危害.生物炭具有比表面积大、孔结构发达和官能团丰富等优点,是一种高效、环保的环境修复吸附剂,在去除废水中的无机氮磷等盐类方面有着巨大的应用潜力.本文对生物炭的制备及改性方法、影响吸附氮磷的主要因素和机理进行了简单的综述.
Abstract
In recent years,due to the increasing content of nitrogen and phosphorus compounds in water,water eutrophication has occurred,and the reduction of water quality has caused harm to the whole ecosystem.Biochar has the advantages of large specific surface area,developed pore structure and rich functional groups.It is an efficient and environmentally friendly environmental remediation adsorbent.It has great application potential in removing inorganic nitrogen and phosphorus salts in wastewater.In this paper,the preparation and modification methods of biochar,the main factors and mechanisms affecting the adsorption of nitrogen and phosphorus were briefly reviewed.
