Biological odour removal device

The embodiment of the utility model discloses biological odour removal device, the foul smell is through setting up in the air inlet entering of casing bottom, with contact of mixed liquid and the quilt including microbial?community and nutrient solution it absorbs to mix liquid, microbial?community is decomposed into the odorless material with the foul smell, the foul smell is set up porous biofilm carrier ball absorption on the biofilm carrier board through the biofilm carrier board, fills and further will in the microbial?community of biofilm carrier ball the foul smell decomposes, spray the net to the biofilm carrier ball sprays mixed liquid, mix liquid and remain the foul smell and fully contact, will it decomposes to remain the foul smell. At above -mentioned in -process, the foul smell process biological odour removal device's multilevel processing mixes the circulation flow of liquid moreover and guarantees microbial?community is in the high activity state all the time, effectively improves the treatm
