摘　　要：去除水体磷酸盐对于控制富营养化现象具有重要作用,吸附法因其效率高、成本低、易操作及污染小等优点而被广泛应用,且改性生物炭对磷酸盐具有更强吸附能力。本综述基于国内外关于改性生物炭吸附水体磷酸盐的研究,总结了常见生物炭制备方法,及对经物理法、化学法、生物法改性后的生物炭性能比较,揭示了不同方法制备改性生物炭在吸附水体磷酸盐实验中的实际效果差异特征。最后针对性的介绍了以藻类、木质素与秸秆三类代表性生物材料制备生物炭采用的最佳改性方案,以期为后续研究及应用提供方向与理论支撑。The removal of phosphate from water bodies plays an important role in controlling the phenomenon of eutrophication,and the adsorption method is widely used because of its advantages of high efficiency,low cost,easy operation,and low pollution.Moreover,modified biochar has a stronger adsorption capacity for phosphate.Based on the domestic and international studies on the adsorption of phosphate by modified biochar,this review summarizes the common preparation methods of biochar and compares the properties of biochar modified by physical,chemical,and biological methods,revealing the characteristics of the differences in the actual effects of modified biochar adsorption of phosphate in water experiments.Finally,the preparation of biochar from three representative biomaterials,algae,lignin,and straw,and the best modification plan were introduced,to provide direction and theoretical support for subsequent research and application.
