The invention discloses a device and method for enhanced treatment of coking wastewater by coupling ultrasonic waves with membrane bioreactors, the device comprises a plurality of groups of membrane bioreactors which are arranged in parallel, the top of each membrane bioreactor is provided with a lifting device with the same width as the membrane bioreactor, and two ultrasonic vibration plates are lifted and placed in the plurality of groups of membrane bioreactors through the lifting devices; the ultrasonic vibration plates emit low-intensity ultrasonic waves through the ultrasonic generator and the wire when the membrane bioreactor operates, so that the two ultrasonic vibration plates work in the multiple groups of membrane bioreactors. According to the invention, the permeability of microbial cell membranes in the membrane bioreactor is improved by using ultrasonic waves, and exchange of intracellular and extracellular substances is accelerated; the secretion and enzyme activity of microbial enzyme in the
