Biological deodorization device and deodorization method Technical Field The invention belongs to the technical field of waste gas treatment, and particularly relates to a biological deodorization device and a deodorization method. Background Malodor treatment in sewage treatment plants, in particular to the development of efficient biological deodorization devices. The deodorizing methods adopted in the sewage plants at present can be roughly classified into a physical method, a chemical method and a biological method. The most widely used malodor control method for urban sewage treatment plants is a biological method. The patent CN218741160U discloses a deodorizing device for sewage treatment, which comprises a spray tower main body, a fixed bracket, a filling material tray and a filling material tray, wherein the fixed bracket is annular and welded on the inner wall of the spray tower main body, the filling material tray is placed on the fixed bracket, a plurality of annularly distributed supporting legs are embedded at the lower end part of the filling material tray, embedded rotating beads are arranged at the lower end part of any supporting leg in a rotating way, the supporting legs extend into the fixed bracket, the rotating beads are in rolling connection with the fixed bracket, and the filling material tray controllably rotates on the fixed bracket through the rotating beads rolling on the fixed bracket. In the deodorizing device for sewage treatment that this scheme provided, the filler tray can rotate, consequently has higher flexibility, ensures that operating personnel can touch each region on the filler tray, consequently at the in-process of packing, can be more even, and deodorizing effect can be better. However, as a traditional odor control treatment device for sewage treatment plants, the biological filter tower is easy to generate acidic substances in the treatment of malodorous substances such as methyl mercaptan, and the acidic substances are easy to acidify a filler layer, and the acidized filler is easy to compact the filler, so that the structure and the void ratio of the filler layer are changed by acidification. In the actual operation process, the wind resistance of the biological filler layer of the biological deodorization device at unit height is related to the air bed flow rate, the filler void ratio and the like, and the air bed flow rate is too high or the filler void ratio is too small to increase the filler wind resistance at unit height, so that the air flow distribution is influenced, and the collection effect of the whole odor collection system and the treatment efficiency of the odor treatment device are further influenced. There are studies on sharing the supporting force of the bottom filler to the filler above through the floating supporting mechanism, reducing the compaction effect and improving the odor treatment effect. The biological deodorizing device of charcoal filler is given like patent CN113181761A, and the biological deodorizing device of charcoal filler includes spray module, filler module, circulation module and pipeline of giving vent to anger, and spray module, filler module and circulation module are independent module, spray module, filler module and circulation module stack and form the trickle filter tower, spray module setting is the humidification of filler module at the top of filler module, and circulation module setting is collected the liquid that filler module dripped in the bottom of filler module and is provided the spray liquid for spraying the module. According to the scheme, the plurality of floating supporting mechanisms are arranged in the filler module, so that the supporting force of the bottom carbonaceous filler to the carbonaceous filler above can be shared, the compaction effect is reduced, and the odor treatment effect is improved. However, only changing the effect of the supporting mechanism on packing compaction is limited, how to provide a biological deodorizing device to improve the porosity of the packing and prolong the service life of the packing through the arrangement of the internal mechanism is a problem to be solved by the person skilled in the art. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a biological deodorization device and a deodorization method, wherein the biological deodorization device comprises a bearing component and a dispersing component, a tray moves along a spiral track to drive a filler layer to rotate, and simultaneously drives a deflector rod and a shifting fork of the dispersing component to rotate, and the filler layer is shifted to loosen a compacted part of the filler layer again, so that the void ratio of the filler layer is improved, and the service life of filler in the filler layer is prolonged. In a first aspect, the invention provides a biological deodorization device, comprising a tower body, wherein the top of the tower body is provided wit
