The invention discloses a beta-CD/waste polyester electrostatic spinning composite nanofiber membrane and a preparation method and application thereof.A CWP spinning solution and a beta-CD solution are placed at the two ends of a receiving roller of an electrostatic spinning machine respectively for opposite spraying, the beta-CD/CWP nanofiber composite membrane of a honeycomb structure is prepared, the porosity of the beta-CD/CWP nanofiber composite membrane is high, beta-CD is of a bowl-shaped structure, and the beta-CD/CWP nanofiber composite membrane is not prone to deformation. The special structures are favorable for reducing the filtering resistance and improving the removal of particulate matters PM and volatile organic gases COFs in the oil smoke, so that excellent comprehensive filtering performance is obtained. 90% of the real oil fume purification performance (gt; 90%) of the composite membrane is tested by adopting an oil fume detection system; the performance is far higher than that of commercia
