摘　　要：水体富营养化问题日益严重,对人类健康和生态系统构成威胁。因此,从水中去除磷成为亟待解决的问题。吸附法因其成熟性和灵活性在众多磷酸盐去除方法中脱颖而出,在众多吸附剂中,生物炭因其稳定性和低廉的制备成本备受关注。然而,天然生物炭吸附能力较差,在复杂的吸附环境中难有良好的表现,因此需要改性以提高其吸附性能。改性生物炭具备高效的吸附性能和低廉的制备成本等优势,已成为去除水中磷酸盐的重要手段之一。生物炭可以通过物理、化学、生物等改性方式以提升生物炭的吸附性能。然而,单一的改性方式往往难以对生物炭的性能提升提供重要。综述了改性生物炭的制备方法、吸附机理和再生应用,探讨了其在实际应用中的潜力及未来研究方向,为水体磷污染治理提供了新的思路和解决方案。The issue of eutrophication in water bodies is becoming increasingly severe,posing threats to human health and ecosystems.Consequently,the removal of phosphorus from water has become an urgent problem to address.Among the various methods for phosphate removal,the adsorption method stands out due to its maturity and flexibility.Biochar,in particular,has garnered attention among many adsorbents because of its stability and low preparation cost.However,natural biochar has poor adsorption capacity and struggles to perform well in complex adsorption environments,necessitating modifications to enhance its adsorption performance.Modified biochar,with its high adsorption efficiency and low preparation cost,has become one of the key means for removing phosphate from water.Biochar can be modified through physical,chemical,and biological methods to enhance its adsorption performance.However,a single modification method often fails to significantly improve the performance of biochar.This paper reviews the preparation methods,adsorption mechanisms,and regeneration applications of modified biochar,discussing its potential in practical applications and future research directions and providing new ideas and solutions for phosphorus pollution control in water bodies.
