基于SR-AOPs处理抗生素废水研究进展

Research progress of antibiotic wastewater treatment based on SR-AOPs

抗生素废水成分、性质复杂,传统处理方法难以有效降解水中抗生素。针对抗生素废水处理难的问题,研究发现使用基于硫酸根自由基(SO_(4)·^(-))的高级氧化技术(SR-AOPs)处理抗生素废水效果很好。系统总结了采用热、光、超声、碱、过渡金属离子、碳材料等方法活化过硫酸盐或亚硫酸盐生成SO_(4)·^(-)处理抗生素废水的效果及其优缺点,指出了将基于SR-AOPs用于抗生素废水处理时有待解决的重要问题,同时提出了基于SR-AOPs在抗生素废水处理方面的未来发展方向。

As the composition and nature of antibiotic wastewater is complex,traditional treatment methods are difficult to effectively degrade antiobiotics in it.Aiming at the difficulty of antibiotic wastewater treatment,the advanced oxidation technology:SR-AOPs based on sulfate free radicals(SO_(4)·^(-))was found to have good treatment efficiency on antibiotic wastewater.The effects,advantages and disadvantages of using heat,light,ultrasound,alkali,transition metal ions,carbon materials and other methods to active persulfate or sulfite so as to generate SO_(4)·^(-)and then to treat antibiotic wastewater,were summarized systematically.The essential problems that need to be solved when using SR-AOPs to treat antibiotic wastewater were pointed out;meanwhile,the future development direction of SR-AOPs in antibiotic wastewater treatment was prospected.
