Abstract
A method for treating tungsten-containing liquid includes: a coagulation treatment step, in which the tungsten-containing liquid is coagulated using an inorganic coagulant; a solid-liquid separation treatment step, in which the coagulated sludge obtained in the coagulation treatment step is separated into solid and liquid components; and a dewatering treatment step, in which the separated sludge obtained in the solid-liquid separation treatment step is dewatered. The method is characterized by a sludge return step, in which a portion of the separated sludge obtained in the solid-liquid separation treatment step is returned to the coagulation treatment step.
