The invention belongs to the technical field of solid waste recycling, and particularly relates to a pretreatment method and device for organochlorosilane waste. The pretreatment method of the organochlorosilane waste, provided by the invention, comprises the following steps: mixing an alkaline waste organic solvent and the organochlorosilane waste in a viscous state, and carrying out a hydrolysis reaction to obtain an organochlorosilane pretreatment solution. According to the method, the alkaline waste organic solvent containing a small amount of water and the viscous-state organochlorosilane waste are mixed for hydrolysis reaction, the speed of the hydrolysis reaction is reduced, the alkaline waste organic solvent can reduce the influence of acid gas generated by the hydrolysis reaction on a system device, and the system device is more environmentally friendly. And the heat value of the obtained organochlorosilane pretreatment liquid is maintained in the treatment process of the waste organic solvent, and o
