Summary:PURPOSE: A method for recovering sericin from the silk refined waste water is provided, therefore the sericin can be easily recovered by adding a high polymer coagulant. CONSTITUTION: The method for recovering sericin comprises the steps of: adjusting pH of the silk refined waste water to 5 to 7; regulating the temperature of the silk refined waste water to less than 40 deg. C; adding 0.5 to 5 ml/l of the high polymer coagulant into the silk refined waste water to coagulate and precipitate sericin; separating the precipitate sericin from the silk refined waste water; and optionally centrifuging the silk refined waste water at 3000 to 5000 rpm for 10 minutes or filtering the silk refined waste water with sieves after adding the high polymer coagulant, in which the high polymer coagulant is selected from the group consisting of polyaluminum chloride, aluminum sulfate, ammonium aluminum sulfate and potassium aluminum sulfate.
