The utility model relates to the technical field of biological deodorization, and discloses an efficient intelligent biological deodorization and waste water resource recycling system which comprises a water tank, and a deodorization bin is fixedly installed on the right side of the top end of the water tank. According to the efficient intelligent biological deodorization and waste water resource recycling system, the key problem that traditional biological deodorization waste gas is difficult to uniformly contact with microorganisms is solved by adopting a staggered distribution structure of the filler plates in the deodorization bin, and in a biological filtration link, malodorous gas can uniformly and stably flow between the filler plates, so that the biological deodorization effect is improved. The device effectively avoids the appearance of an area with too fast or too slow flow velocity, enables the gas to be in full contact with microorganisms in the filler, greatly prolongs the retention time of the waste gas, further remarkably improves the decomposition efficiency of the microorganisms on malodorous substances, and can further irradiate the waste gas to achieve the deodorization and sterilization effects due to the design of the ultraviolet lamp. And the deodorization effect is qualitatively improved.

This invention relates to the field of microbial inoculants, and particularly to a compound inoculant for controlling soil-borne diseases in farmland based on endophytic bacteria, and its preparation method. The compound inoculant is composed of a main inoculant, auxiliary inoculants, and a fungicide. The main inoculant includes *Talaromyces sp. strain HBUM07170*, *Rhizobium sp. NXC24*, and *Methylobacterium brachiatum*, while the auxiliary inoculants include *Mycobacterium sp.*, *Caulobacter sp.*, *Penicillium sp.*, and *Pyronema omphalodes*, with each strain having a concentration of not less than 10%. 8 The concentration of CFU / ml is 1:1 (main bacterial agent mixture to auxiliary bacterial agent mixture), and tebuconazole is used as the fungicide. During preparation, each bacterial strain is activated and cultured separately, then mixed according to the specified volume ratio before adding tebuconazole and stirring to dissolve. This invention's compound bacterial agent exhibits synergistic effects among the bacterial strains, effectively antagonizing Fusarium oxysporum, reducing the incidence and mortality of lily wilt, and promoting plant growth. It combines biological control with chemical-assisted antibacterial effects and can be used in the preparation of control formulations for soil-borne diseases in farmland and lily wilt.
