Biological deodorizing method for modularized treatment of large-air volume odor and device

The invention provides a biological deodorizing method for modularized treatment of large-air volume odor and a device. The device comprises a microbial filter tank, wherein the microbial filter tankis provided with an odor gas inlet and a purified gas outlet, a large gas distribution area and a microbial treatment mechanism are arranged in the microbial filter tank, the microbial treatment mechanism comprises a microbial treatment unit and a small gas distribution area, and the small gas distribution area is communicated with the large gas distribution area. The biological deodorizing devicefurther comprises a spraying mechanism for spraying the microbial treatment unit. According to the method and the device, the problem in design and construction of a biological deodorizing system fortreatment of large-air volume odor, particularly odor with the blast volume of 100,000 cubic meters per hour, problem in uniformity of gas distribution in treatment of the large-air volume odor and problem of failure caused by
