Problems solved by technology

Existing microbial deodorants have problems such as microbial symbiosis and poor adaptability to different environments, poor degradation of hydrogen sulfide and ammonia, and slow growth and reproduction after spraying and use. It is difficult to achieve the purpose of rapid deodorization, which limits microbial deodorization. Further development of odorants

Abstract

The invention discloses a preparation method of a compound microbial deodorant. The compound microbial deodorant is prepared by inoculating bacterial liquid onto a fermentation medium and mixed fermentation; the bacterial liquid is prepared from lactobacillus zeae, lactobacillus fermentum, saccharomyces cerevisiae, candida ethanolica and bacillus kochii; and compositions of the fermentation mediumare molasses and zeolite powder. According to the preparation method, the lactobacillus zeae and the lactobacillus fermentum are common probiotics in the microbial deodorant, growth and reproductionof putrefactive bacteria in waste after a meal can be inhabitated, while organic acid or other substances produced by the saccharomyces cerevisiae and the candida ethanolica can fix nitrogen to convert the nitrogen into ammonia nitrogen in a form of a mechanical state or a complex state, and thus emission of ammonia is reduced.

Description

technical field [0001] The invention belongs to the technical field of microbes and environmental protection, and in particular relates to a compound microbial deodorant, a preparation method and an application. Background technique [0002] Food waste contains extremely high organic matter and moisture, and it is easy to rot and deteriorate during stacking and transportation and produce foul odors. These gases are caused by the fermentation of spoilage microorganisms. During the natural stacking process of food waste, when there is sufficient oxygen, the organic components such as protein, oil, sugar, etc., are completely degraded by aerobic bacteria to produce irritating gas NH 3 , CO 2 Wait. When oxygen is insufficient, anaerobic bacteria decompose organic matter into incomplete oxidation products such as sulfur-containing compounds such as H 2 S, mercaptans, volatile fatty acids, etc., and nitrogen-containing compounds such as amines, amides, etc., these substances ha...
