The invention belongs to the chemical engineering field, in particular relates to a method for preparing ammonium polyvandata with vanadium-containing solution. The method uses the vanadium-containing solution produced with the traditional sodium roasting-water immersing technology as the raw material. First, vanadium combines with added calcium compounds and produces calcium vanadate, which reacts with ammonium bicarbonate and transfers vanadium into the solution but transforms calcium into more insoluble calcium carbonate; the ammonium polyvandata is produced with the separated solution under appropriate pH and heating conditions. After redissolution of calcium vandata, the ammonium bicarbonate containing less than 0.1percent of SUM (Na2O+K2 O) can be obtained. The ammonium bicarbonate can be used for production of vanadium trioxide and vanadium pentoxide with exceedingly low contents of potassium and sodium; and the ammonia content of vanadium-precipitation waste water is only 60percent to 75 percent of vanadium-extraction waste water in traditional technologies. The invention has very promising application prospect.
