Embodiment 1

[0013] A preparation method of an activated carbon deodorant, in a mixed solution containing 0.03% of ferrous chloride, 0.02% of zinc sulfate, and 3% of glucose, the number of bacteria inserted is basically the same (all are 10 3 ~10 4 pcs / ml) of Bacillus subtilis and Aspergillus rhizogenes to obtain a mixed bacterial solution, the sum of the bacterial counts of Bacillus subtilis and Aspergillus rhizogenes in the mixed bacterial solution is 10 6 ~10 7 1 / ml; then add 0.2 grams of activated carbon particles with a particle size of 10 to 30 meshes per ml of the mixed bacterial solution, soak for 10 to 30 minutes; after soaking, take out the activated carbon particles and drain for 5 to 10 minutes to obtain an activated carbon deodorant.

Embodiment 2

[0015] Basically the same as Example 1, the difference is that the mass percent concentration of ferrous chloride is 0.01%, the mass percent concentration of zinc sulfate is 0.05%, the mass percent concentration of glucose is 2%, and the Bacillus subtilis of the access is and Aspergillus rhizogenes are replaced by Bacillus subtilis, and the bacterial count of Bacillus subtilis in the mixed bacterial solution is 10 6 ~10 7 pcs / ml.

Embodiment 3

[0017] Basically the same as Example 1, the difference is that the mass percentage concentration of ferrous chloride is 0.05%, the mass percentage concentration of zinc sulfate is 0.01%, the mass percentage concentration of glucose is 5%, and the Bacillus subtilis of the access is and Aspergillus rhizogenes are replaced by yeast, and the number of yeast in the mixed bacterial solution is 10 6 ~10 7 pcs / ml.

Abstract

The invention discloses a preparation method for an active carbon deodorant and application of the active carbon deodorant in removal of fish meal processing odor. The preparation method comprises the following steps of: inoculating at least one of bacillus subtilis, yeast, bacillus natto and rhizopus into a mixed solution containing ferrous chloride, zinc sulfate and glucose, adding active carbon particles with the particle size of 10-30 meshes, soaking for 10 to 30 minutes, taking the active carbon particles out, and draining for 5 to 10 minutes to obtain the active carbon deodorant. The ferrous chloride, the zinc sulfate, the glucose and microorganisms are adsorbed in the active carbon deodorant, the ferrous chloride, the zinc sulfate and the glucose contribute to growth and reproduction of the microorganism and have synergism for deodorizing; the microorganisms can degrade odor adsorbed by the active carbon particles, so that the effect of adsorbing the odor is good, the adsorbed odor can be degraded, and a problem that the active carbon is required to be replaced or desorbed after adsorption saturation is solved; meanwhile, a problem of secondary pollution during desorption of the active carbon is solved, and the active carbon deodorant has the deodorizing rate of over 99 percent when applied to removing the fish meal processing odor.

Description

technical field [0001] The invention relates to a deodorant, in particular to a preparation method of an activated carbon deodorant and an application for removing odor from fish meal processing. Background technique [0002] In the process of fish meal processing, affected by the decay of raw material organisms, a large amount of unpleasant odor gases such as sulfur and organic amines will be produced in the whole high-temperature cooking and drying process. At present, the methods of treating malodorous gas include: burning malodorous gas, oxidizing malodorous gas by oxidant, removing malodorous gas by ozone or ultraviolet rays, adsorbing malodorous gas by activated carbon, and degrading malodorous gas by microorganisms. For example, the publication number is CN101385864, the invention patent application titled as medium deodorant, deodorant manufacturing method and application, discloses the preparation of deodorant which uses activated carbon as base material and adheres...
