Method of treating waste solution of non-silver halide light-sensitive material.

摘要

Disclosed is a method of separating a waste solution of a non-silver halide light-sensitive material into liquid and solid comprising the steps of: adding at least one of a neutralizer and a flocculant to the waste solution under stirring to precipitate solid, subjecting the mixture to centrifugal filtration to separate it into filtrate and the precipitated solid, and concentrating the filtrate by heating to further separate it into liquid and solid, by which solid and liquid can be separated sufficiently. <IMAGE>
