The invention discloses a regeneration method for an arsenic poisoning selective catalytic reduction denitration catalyst. The regeneration method comprises the following four steps of blowing ash, dipping, dipping, and drying and roasting. According to the regeneration method, an arsenic component which can cause SCR (Selective Catalytic Reduction) denitration catalyst poisoning can be effectively removed by using regenerated liquid and active ingredients can be supplemented; an SCR denitration catalyst obtains a certain arsenic poisoning resisting capability; meanwhile, a regeneration process is greatly simplified and the regeneration cost of the SCR denitration catalyst is reduced; with the adoption of the method, the regenerated denitration catalyst can be used for carrying out denitration activity detection and the denitration rate can be up to 80-88%.
