摘　　要：磷是引起水体富营养化、藻类爆发的主要控制因素,从水中去除磷是控制水体富营养化的一项重要举措。本文综述了用农业废弃物作为吸附剂去除水体中磷的研究进展。研究发现为提高磷的去除效率,需要对农业废弃物进行改性。吸附剂不同和改性方法不同,吸附机理和影响吸附效率的因素也不同。采用农业废弃物去除水中的磷具有成本低、吸附材料易得、去除效率高、能对磷进行回收、不会对环境产生影响等优点。Phosphorus is the main control factor to cause eutrophication and algae bloom of water body,and then phosphorus removal from water body is an important measure to control water eutrophication. The research progress that taking the agricultural residues as the absorbents for removing phosphorus from water body is reviewed herein. The research finds out that the modification is necessary to be made on the agricultural residues for enhancing the removal efficiency. For different absorbents and modifying methods,the absorption mechanism and the factors affecting the adsorbing efficiency are different as well. Removing phosphorus from water body with the agricultural residues has the merits,such as lower cost,accessible absorbing materials,higher removal efficiency,available recollection of phosphorus,without environment impact,etc.
