Zusammenfassung:	The present invention relates to the field of chemical engineering, and specifically relates to a method using highly concentrated vanadium solution for manufacturing ammonium polyvanadate. The invention addresses the issues of the prior art including the limitation of using only a low concentration vanadium solution to perform vanadium precipitation, long manufacturing process, high production cost, and the like. Provided is a method using a highly concentrated vanadium solution for vanadium precipitation with a low production cost and high vanadium precipitation efficiency. The method comprises: adjusting the highly concentrated vanadium solution to a suitable temperature and pH, adding an ammonium salt, then slowly adding a powdered material comprising vanadium into the solution to perform a reaction, and obtaining the ammonium polyvanadate after the reaction is complete. The technical solution effectively addresses the issue of vanadium precipitation with a highly concentrated vanadium solution, and can i
