微藻处理含抗生素类废水研究进展

Research progress on treatment of antibiotic-containing wastewater by microalgae

随着抗生素的广泛应用,含抗生素类废水的处理问题已然迫在眉睫。微藻技术已被证实具有降解抗生素污染物的潜力,现已被行业学者广泛研究。微藻作为混合营养型生物,可以通过吸收CO_(2)和营养物质来合成糖类、蛋白质和脂质等化合物,现已被证实具有降解污染物的潜力。综述了利用微藻处理含抗生素废水的传统方法和新型方法、多种方法协同处理的效果及其优劣势。探讨了处理后微藻的生物质合成情况、抗生素的降解机制并比较了这些机制的贡献。最后总结了目前利用微藻处理含抗生素类废水的不足并且阐明了后续需重点关注的研究方向,以期为日后微藻处理抗生素进一步规模化发展和资源化利用打下基础。

With the wide application of antibiotics,the treatment problem of wastewater containing antibiotics is al⁃ready imminent.Microalgae technology has been proved to have the potential to degrade antibiotic pollutants,and has been widely studied by industry scholars.As mixotrophic organisms,microalgae can synthesize compounds such as sugars,proteins and lipids by absorbing CO_(2) and nutrients,which have been confirmed to have the potential to de⁃grade pollutants.This paper summarizes the results of the traditional and new methods of microalgae and various methods.The biomass synthesis of treated microalgae,the mechanisms of antibiotic degradation were explored and the contributions of these mechanisms were compared.Finally,the shortage of microalgae treatment of antibioticcontaining wastewater is summarized and the following research direction should be clarified,in order to lay a foun⁃dation for the further large-scale development and resource utilization of microalgae treatment in the future.
