description The invention discloses a continuous pre-treatment device, a pre-treatment method and an emergency treatment method of a pre-polymerization solution, and belongs to the field of pre-polymerization solution pre-treatment. The pretreatment device comprises a batching tank, an intermediate tank, a pre-deoxygenization tank, a deoxygenization packed column, a high-purity nitrogen source, an initiator tank and a reflux oxygenation tank. The treatment method comprises the following steps: deoxidizing through a pre-deoxidizing tank until the oxygen content of a liquid phase reaches 0.3-0.5 ppm, then feeding the liquid phase into a deoxidizing packed column for deep deoxidizing, and finally continuously deoxidizing the pre-polymerized liquid continuously entering the system when the minimum oxygen content reaches 2ppb, thereby meeting the continuity of photo-induced polymerization production. According to the present invention, the pre-deoxidizing tank and the deoxidizing filler column are sequentially combined to car
