摘　　要：废弃物再生生物质炭在改性处理后,比表面积、孔径、孔容积、官能团、疏水性以及微观形貌等都会发生很大变化,作为一种低成本高效吸附剂,在废水处理领域应用广泛。针对近几年的相关文献,介绍了生物质炭通过活化法和复合法改性后在废水处理领域的最新进展;着重分析了改性生物质炭在氮和磷污染废水、重金属污染废水、酚类物质及多环芳烃污染废水、抗生素污染废水及有机染料污染废水领域的应用;最后提出了未来生物质炭废水处理领域的研究方向和发展趋势,以期为生物质炭在废水处理领域的应用提供思路和参考。After waste recycled biochar is modified and treated, the specific surface area, pore size, pore volume,functional group, hydrophobicity and micro morphology will change greatly, as a low-cost and high-efficiency adsorbent, it is widely used in the field of wastewater treatment. In this article, based on the relevant literature in recent years, the latest progress of biochar modified by the activation method and the composite method in the field of wastewater treatment was introduced. The application of modified biochar in the fields of wastewater polluted by nitrogen and phosphorus, wastewater polluted by heavy metals, wastewater polluted by phenols and polycyclic aromatic hydrocarbons, wastewater polluted by antibiotics and wastewater polluted by organic dyes was emphasized.Finally, the research direction and development trend in the field of biochar wastewater treatment in the future were proposed, in order to provide ideas and reference for the application of biochar in the field of wastewater treatment.
