摘要: |
水环境中的抗生素污染问题已成为当前环境保护领域的重大挑战之一,这类污染物不仅会引起严重的水生生物生态毒性效应,破坏水生态系统的平衡,还可能会诱导产生抗性基因,对生态安全造成严重的风险和潜在威胁。高级氧化技术因其具有对抗生素的高效降解能力而备受关注,这一技术通过产生强氧化性的自由基,快速氧化分解抗生素,从而达到去除抗生素的目的。近年来,该技术已经被广泛研究并逐步应用于含抗生素废水处理中。然而在高级氧化降解过程中,抗生素因不完全降解和矿化会产生大量中间产物,这些中间产物的生态毒性不容忽视,其可能同样会对水生生态系统造成负面影响。关于中间产物的生态毒性研究是本领域的科研热点,也是关乎高级氧化技术安全性应用的关键。系统总结并分类对比各典型高级氧化技术降解抗生素的机制和技术特点,重点介绍抗生素高级氧化降解产物的生态毒性研究进展,并系统分析该方向研究未来发展趋势。 |

Abstract: |
The issue of antibiotic pollution in aquatic environments has become one of the major challenges in the field of environmental protection. These pollutants not only cause serious ecological toxicity effects on aquatic organisms, disrupting the balance of aquatic ecosystems, but may also induce the production of resistance genes, posing serious risks and potential threats to ecological safety. Advanced oxidation technology has attracted much attention due to its efficient degradation ability of antibiotics. This technology generates strong oxidizing free radicals, rapidly oxidizes and decomposes antibiotic components, thereby achieving the goal of removing antibiotics. In recent years, this technology has been widely studied and gradually applied in practical application of antibiotic-containing wastewater treatment. However, in the process of advanced oxidative degradation, antibiotics produce a large number of intermediate products due to incomplete degradation and mineralization. The ecological toxicity of these intermediate products cannot be ignored, as they may also have negative impacts on aquatic ecosystems. The research on the ecotoxicity of intermediate products is a hot topic in this field, and it is also crucial for the safe application of advanced oxidation technologies in the future. This article systematically summarizes and categorizes the mechanisms and technical characteristics of various typical advanced oxidation technologies for degrading antibiotics.It focuses on introducing the research progress on the ecological toxicity of antibiotic advanced oxidation degradation products, and systematically analyzes the future development trends in this research direction. |
