High-concentration odor biological treatment device

The utility model discloses a biological treater for high-concentration odor, which relates to the field of biological purification and comprises an odor treatment box, a liquid storage reaction layer is arranged at the bottom end in the odor treatment box, a second isolation plate is arranged between the liquid storage reaction layer and an odor purification layer for separation, and the bottom end of the second isolation plate is connected with a connecting frame. A reaction device is mounted at the bottom end of the connecting frame, and a bottom end supporting frame is arranged at the bottom end of the odor treatment box. When the odor input pipe inputs odor, the output cylinder connected with one side of the odor input pipe can expand the gas transmission range, meshes are formed in the surface of the output cylinder, when the odor is output from the meshes, the water pump pumps reaction liquid into the liquid spraying layer at the moment, the liquid spraying head sprays vaporific liquid to react with th
