The invention relates to the technical field of screw vacuum pumps, and discloses a screw vacuum pump silencing assembly which comprises a silencing shell, one side of the top of the silencing shell is communicated with a first air inlet pipe, one end of the silencing shell is communicated with a second air inlet pipe, the bottom of one end of the silencing shell is communicated with a liquid drainage pipe, and the other end of the silencing shell is communicated with an air outlet pipe. A partition plate is fixedly connected to the inner side of the silencing shell, and a one-way pipe is embedded into the partition plate, so that the problems that according to an existing silencing device, holes are formed outside a pipeline, noise can be released through the holes, the sound pressure in the pipe is reduced, reflection and propagation of the noise in the pipe can be reduced, and the silencing effect is achieved are solved; and moreover, the turbulence effect can be introduced to weaken propagation and energy
