Abandoned denitration catalyst recycling alkaline-washing solution and method

The invention discloses an abandoned denitration catalyst recycling alkaline-washing solution and method and aims at inventing an abandoned catalyst suitable for treatment and capable of restoring the activity reduced by active phosphorus and arsenic. The abandoned catalyst can be recovered and re-applied to a novel catalyst preparation process, and various performance parameters are equivalent to the performance of an unused novel catalyst. 本发明公开了种废弃脱硝催化剂回收利用碱洗溶液及方法，目的在于发明种适合处理可恢复活性的磷或砷造成的活性下降的废弃催化剂，使其得以回收重新应用到新鲜催化剂的制备工序中，且各项性能参数与未使用的新催化剂性能相当。
