The invention provides a method for preparing cupric sulfide, copper carbonate and sodium chloride from waste residue copper sludge, which comprises the following steps: blending waste residue copper sludge, which is obtained in the vat grey BG production process, with industrial water to obtain slurry; filtering to obtain cupric sulfide and a filtrate 1; reacting the filtrate 1 with hydrochloric acid to obtain a mixed solution containing cupric chloride, sodium chloride and sodium sulfate, and meanwhile, discharging hydrogen sulfide gas; filtering the mixed solution to obtain a small amount of filter cake impurities and a clear filtrate; carrying out atmospheric distillation on the clear filtrate to remove low-boiling organic impurities, and reacting with calcium chloride to remove sodium sulfate, thereby obtaining a filtrate 3; reacting the filtrate 3 with a sodium carbonate solution to generate copper carbonate precipitate and sodium chloride, and filtering to obtain cupric hydroxide and a filtrate 4; and carrying out reduced pressure distillation on the filtrate 4 to obtain a supersaturated sodium chloride solution, crystallizing sodium chloride, and filtering to obtain sodium chloride and a filtrate 5.
