The invention discloses a method and equipment for comprehensive recycling treatment on organic silicon slag slurry. The method comprises the following steps: 1, separating organic silicon slag slurryby using a distiller so as to obtain gas-phase high-boiling residues and solid residues; 2, dissolving the solid residues with an acid, and after dissolution is completed, carrying out filtration andseparation so as to obtain a copper-containing solution and filter residues; 3, washing the filter residues obtained in the step 2, and drying so as to obtain silicon powder; 4, putting zinc powder into the copper-containing solution separated in the step 2 to carry out replacement so as to obtain metallic copper powder; 5, condensing the gas-phase high-boiling residues obtained in the step 1 soas to obtain liquid high-boiling residues, and carrying out catalytic cracking on the liquid high-boiling residues with a catalyst; 6, carrying out fractionation on a gas phase obtained through catalytic cracking in the step 5, and collecting monomethyl trichlorolsilane, dimethyl diclorossilane, trimethylchlorosilane and monomethyl hydrosilane. By adopting the method and the equipment, copper andsilicon resources in organic silicon slag can be effectively recycled, thus being environmental-friendly and economic.
