description The invention discloses a method for producing silver chloride and bismuth nitrate from a mercury-containing waste liquid. The method comprises feeding a waste mercury catalyst into a seal-type distiller, carrying out distillation so that mercuric chloride is directly sublimated to form gas and is cooled to form a liquid, carrying out a reaction process on the mercuric chloride solution and the silver nitrate solution to obtain a silver nitrate precipitate-mercury nitrate mixed solution, carrying out enclosed pumping filtration to obtain silver chloride filter cake, carrying out washing, drying, crushing and packaging to obtain a silver chloride product, further processing the clear mercury nitrate solution, carrying out a reaction process on the mercury nitrate solution and a bismuth hydroxide emulsion to produce a mercuric oxide precipitate-bismuth nitrate mixed solution, filtering the mixed solution to obtain mercuric oxide filter cake, carrying out washing, spin-drying, drying, crushing and packaging to o
