摘要： A method for recovering a lithium bromide absorption liquid from a waste lithium bromide absorption liquid is provided to prepare a recycled absorption liquid with a level of at least 99% compared with a new absorption liquid by eliminating copper, potassium and iron presenting in the waste absorption liquid, and removing ammonium ions, sulfate ions and suspended solids from the waste absorption liquid. A method for recovering a lithium bromide absorption liquid from a waste lithium bromide absorption liquid comprises the steps of: (a) stationing a waste lithium bromide absorption liquid(1) and injecting a coagulant into the waste lithium bromide absorption liquid to remove inorganic impurities from the waste lithium bromide absorption liquid; (b) allowing a filter(4) to filter the waste lithium bromide absorption liquid having the inorganic impurities removed therefrom to eliminate suspended impurities of at least 5 mum from the waste lithium bromide absorption liquid; (c) concentrating the waste lithium bromide absorption liquid having the suspended impurities eliminated therefrom; and (d) injecting a corrosion inhibitor into the concentrated absorption liquid, adjusting pH of the absorption liquid, and eliminating suspended impurities of at least 1 mum from the pH-adjusted absorption liquid using a filter(7).
