摘要
磷是生命过程中的必需元素,然而现如今世界磷矿资源极度匮乏,同时流失的磷又造成严重的富营养化污染。第一次全国污染源普查技术报告指出,农业源是我国磷排放的首要源头,因此回收农业废水磷素资源具有重要的研究价值。生物碳作为一种经济高效环境友好的新型吸附材料,近年开始用于回收废水中的磷素。本文将通过介绍生物碳性质、影响因素、吸附机理及解磷特性等内容,探讨生物碳回收农业废水中磷素的研究前景。
Phosphorus is an essential element in life.However,the world phosphorus rock resource is increasingly lacking and the flow of the phosphorus to wastewater cause serious eutrophication pollution.The first national pollution source census technical report shows that agriculture is the primary source of phosphorus discharge.Therefore,recovery and reuse of phosphorus from agricultural wastewater is meaningful.Biochar,as a new kind of economic,efficient,and environmental friendly adsorbent,has been used in wastewater treatment for phosphorus recovery.The advances and prospects in phosphorus recovery from agricultural wastewater by biochar adsorption have been reviewed through the analysis of biochar properties,influence factors,adsorption mechanism,and phosphorus release characterics.
