The invention discloses a temporary culture purification system which comprises a frame body. A plurality of temporary culture rooms formed by partition plates are distributed inside the frame body in an array mode. A top plate is laid on the upper portion of the frame body. A platform further comprises an auxiliary platform. The auxiliary platform comprises an auxiliary platform floating plate. A plurality of air bags are arranged on the outer edge of the auxiliary platform floating plate. The lower portion of the auxiliary platform floating plate is connected with an immersible pump through a pipeline. A filter is arranged at the end of a water inlet of the immersible pump. The outlet end of the immersible pump is communicated with a main water pipe arranged inside the frame body through a connecting pipeline. A power source supplying electric energy to the immersible pump is further arranged on the auxiliary platform floating plate. A plurality of branch pipes are connected to the main water pipe. Each branch pipe is located inside one temporary culture room. A plurality of water outlets are formed in the sections, inside the temporary culture rooms, of the branch pipes. Valves are arranged on the main water pipe and the branch pipes. A valve cover plate is arranged on the top plate and the valves are located below the valve cover plate.
