化学修饰生物吸附剂处理重金属废水的研究进展

Research Progress of Chemically Modified Biosorbent for Heavy Metal Wastewater Treatment

工业的快速发展产生了大量的重金属废水,由于重金属具有不可降解性,导致其在环境中不断累积,对人类和环境健康造成严重影响。在众多处理重金属废水的方法中,生物吸附法因具有反应条件温和、可同时处理多种重金属离子的优点而被广泛应用。但单一生物吸附剂往往无法满足对目标金属离子的高效去除,因此需要对其进行化学修饰以获得更高效的生物吸附剂。分析了重金属废水的特性,归纳总结了化学修饰生物吸附剂的方法,综述了经化学修饰后生物吸附剂处理重金属废水的研究现状,为化学修饰生物材料的进一步发展提供参考。

The rapid development of industry has generated a large amount of heavy metal wastewater,and the non-degradability of heavy metals has led to their continuous accumulation in the environment,causing serious impacts on human and environmental health.Among the many methods for treating heavy metal wastewater,the biosorption method is widely used because of the advantages of mild reaction conditions and the ability to treat a variety of heavy metal ions at the same time.However,a single biosorbent is often not able to meet the high efficiency removal of the target metal ions,therefore it needs to be chemically modified in order to obtain a more efficient biosorbent.The study analyzes the characteristics of heavy metal wastewater,summarizes the methods of chemically modified biosorbents,and focuses on the current research status of chemically modified biosorbents for treating heavy metal wastewater,so as to provide reference for the further development of chemically modified biomaterials.
