Fracturing flowback fluid (FFF) including various kinds of organic pollutants that do harms to people and new treatments are urgently needed. Advanced oxidation processes (AOPs) are suitable methods in consideration with molecular weight, removal cost and efficiency. Here, we summarize the recent studies about AOP treatments towards organic pollutants and discuss the application prospects in treatment of FFF. Immobilization and loading methods of catalysts, evaluation method of degradation of FFF, and continuous treatment process flow are discussed in this review. In conclusion, further studies are urgently needed in aspects of catalyst loading methods, macromolecule organic evaluation methods, industrial process, and pathways of macromolecule organics' decomposition.
压裂返排液（FFF）含有各种对人体有害的有机污染物，因此迫切需要新的处理方法。考虑到分子量、去除成本和效率，高级氧化工艺（AOPs）是合适的方法。在此，我们总结了近期关于AOPs处理有机污染物的研究，并讨论了其在压裂返排液处理中的应用前景。本文综述了催化剂的固定化和负载方法、压裂返排液降解的评价方法以及连续处理工艺流程。总之，在催化剂负载方法、大分子有机物评价方法、工业工艺以及大分子有机物分解途径等方面迫切需要进一步研究。
