Composite microbial preparation for deodorization

Abstract

The invention discloses a composite microbial preparation for deodorization. The preparation is prepared from streptococcus thermophilus, pseudomonas putida, rhodopseudomonas palustris, bacillus pumilus, lactobacillus acidophilus and trichoderma viride. According to the invention, through the good synergistic effect of various harmless microorganisms, the fermentation and decomposition of odor arepromoted, the generated malodorous gases such as NH3 and H2S are absorbed and degraded, the malodorous gases are eliminated, and the production of the malodorous gases is fundamentally solved; due tothe fact that the microbial deodorizer achieves the purpose of deodorization by decomposing and converting odor through microorganisms, the cost is low, the deodorization effect is good, and more nitrogen nutrients can be reserved.

Description

technical field [0001] The invention relates to the related field of compound microbial preparations, in particular to a compound microbial preparation for deodorization. Background technique [0002] The stench emitted in the air is mainly composed of acid-based odor represented by lower fatty acids, alkali-based odor represented by ammonia, and sulfur-based odor represented by mercaptans. At present, the conventional methods for removing stench mainly include: chemical method, Physical methods, biological methods, etc., and chemical methods use deodorants and fragrances to reduce odors. The use of chemical deodorants cannot completely remove odor source substances, and the deodorization effect is not sufficient and thorough. The fragrances used at the same time Sometimes because the masking fragrance is too strong, it will bring unpleasant odors. The physical method uses absorbents to absorb the odorous substances into the micropores of the absorbent. However, once the abs...

[0002] The stench emitted in the air is mainly composed of acid-based odor represented by lower fatty acids, alkali-based odor represented by ammonia, and sulfur-based odor represented by mercaptans. At present, the conventional methods for removing stench mainly include: chemical method, Physical methods, biological methods, etc., and chemical methods use deodorants and fragrances to reduce odors. The use of chemical deodorants cannot completely remove odor source substances, and the deodorization effect is not sufficient and thorough. The fragrances used at the same time Sometimes because the masking fragrance is too strong, it will bring unpleasant odors. The physical method uses absorbents to absorb the odorous substances into the micropores of the absorbent. However, once the absorbent absorbs the odorous substances, it is difficult to desorb and cannot be reused and difficult to handle. , causing secondary pollution to the environment. The biological method mainly digests and decomposes the odor source substances through the biological metabolic process of microorganisms and related enzymes. This method uses mild conditions, eliminates the odor source substances thoroughly, and will not cause secondary pollution to the environment

[0003] The use of microorganisms as deodorants is a worldwide trend in harmless garbage, resource treatment and sewage treatment. It is also a major technological breakthrough in the field of environmental protection in my country. Phagocytosis and decomposition have the deodorizing effect of treating both symptoms and root causes. However, although the microbial deodorants on the domestic market can relieve the stench of organic waste to varying degrees, the effect is not ideal, and the production process is relatively cumbersome.
