The invention relates to a method for recovering waste household appliances by harmlessness and reclamation. The method comprises the following steps of: disassembling and classifying waste household appliances; carrying out harmless treatment on CRT glass obtained by classifying in the disassembling and classifying step; treating chlorofluorocarbon (CFC) recovered in the disassembling and classifying step; treating printed circuit boards and metal plastics obtained by classifying in the disassembling and classifying step: firstly, separating out plastics and metal; then carrying out acid leaching on the metal; next, sequentially carrying replacement on leaching liquid to extract Ag, electrolysis to extract Cu and alkali fusion to extract Au; and recovering intermediate products generated in the treatment process. The method can sufficiently and harmlessly treat displays, circuit boards, and the like and sufficiently extract resources such as Hg, Cu, Fe, Sn, Pb, Au, Ag, plastics, trace Cd, and the like. The method avoids new pollutants generated by disposal, and used reagents have no poison and low price, thus the method has good industrial promotional value, better environmental benefit, economic benefit and social benefit and wide development prospect.
