The rapid development of modern industries is accompanied with the aggravating water heavy metal pollution, which poses a potential threat to the aquatic environment and the health of local populations. As an efficient and economical adsorbent, biochar demonstrates the adsorption capacity for heavy metal ions and its adsorption capacity is significantly enhanced after modification. Therefore, biochar can effectively mitigate environmental pollution. By reviewing the existing studies, we summarize the modification methods of biochar, compare the advantages and disadvantages of physical, biological, and chemical modification methods, analyze the effects of modification on the adsorption capacity of biochar for heavy metal ions, and expound the modification mechanism of biochar. On this basis, this article puts forward the future research directions of the application of biochar in treating coexisting pollutants, aiming to provide a reference for the application of biochar in the purification of heavy metal-containing wastewater.
现代工业的快速发展伴随着水体重金属污染的加剧，这对水生环境和当地居民的健康构成了潜在威胁。作为一种高效且经济的吸附剂，生物炭展现出对重金属离子的吸附能力，并且在改性后其吸附能力显著增强。因此，生物炭能够有效减轻环境污染。通过回顾现有研究，我们总结了生物炭的改性方法，比较了物理、生物和化学改性方法的优缺点，分析了改性对生物炭吸附重金属离子能力的影响，并阐述了生物炭的改性机理。在此基础上，本文提出了生物炭在处理共存污染物方面应用的未来研究方向，旨在为生物炭在含重金属废水净化中的应用提供参考。
