In addition, nitrification and denitrification may be smoothly performed by sludge communities existing in layers in the aerobic granular sludge, and solid-liquid separation may be performed in a short amount of time due to the excellent precipitation performance of the granular sludge, thus enabling a smooth post-treatment process.

The present invention relates to a method for recovering vanadium and tungsten from a leach solution of a waste denitrification catalyst, and more specifically, to a method for recovering vanadium and tungsten from a leach solution of a waste denitrification catalyst comprising the steps of: recovering vanadium by adding acid to a leach solution of a waste denitrification catalyst, and then adding a calcium compound, thereby precipitating the vanadium; and, after recovering the vanadium, recovering tungsten by adding acid to the remaining leach solution, and then adding a calcium compound, thereby precipitating the tungsten.

There are a lot of toxic gases in coal combustion exhaust, such as nitrogen dioxide, sulfur dioxide, nitric oxide, CO, etc. which can not be discharged into the atmosphere before going through the exhaust gas cleaner and meeting the emission standards. Tungsten trioxide as co-catalyst to play carrier sintering resistance, anti-alkali metal and sulfur poisoning in SCR denitration catalyst, thus enhances the efficiency of denitrification.
