Problems solved by technology

In some microbial solid deodorizing products, there are only a single type of bacteria, which can only help to ripen the feces or mix them in cat litter, and the filler melamine formaldehyde resin and other components cannot be naturally degraded, which has caused new pollution on the contrary.
In addition, because there is no multi-layer slow-release structure, the onset time is relatively short

Embodiment 1

[0064] Layer-by-layer slow-release biological deodorant in the biological deodorant of the present invention and its preparation and use method

[0065] In this example, the layer-by-layer slow-release biological deodorant uses five kinds of mixed bacteria to absorb and degrade odorous gas molecules, and the ingredients include active bacteria, glucose, corn starch, compressible starch, degradable water-soluble film and activated carbon. The layer-by-layer slow-release biological deodorant particle structure is as follows: figure 1 As shown, there are three areas in the cross-section of the layer-by-layer slow-release biological deodorant particles, which are separated by two layers of degradable water-soluble films 3, the filling 2 is embedded with a variety of active bacteria 1 and during the filling of the adsorbent, the filling 2 is composed of Glucose, corn starch, and compressible starch are composed together.

[0088] In the biological deodorant of the present invention, the coated biological deodorant and its preparation and use method

[0089] The particle structure of coated biodeodorant is as follows: image 3 As shown, there is only one area in the cross-section of the coated biological deodorant particle, and the microporous filter membrane 4 wraps the filler 2, and the filler 2 is embedded with a variety of active bacteria 1 and adsorbents, wherein the filler 2 is composed of nutrients and viscose. The mixture is composed together, and the microporous filter membrane 4 is covered with small holes, and the pore diameter is less than 1 μm.

[0090] 1. Coated biological deodorant

[0091] Coat the particle surface with a microporous membrane without the need for a degradable water-soluble membrane in the particle. In the water body, the active bacteria are activated by water, use the glucose in the particles to reproduce rapidly, absorb and decompose pollutants in the water bod...

Abstract

The invention discloses a biological deodorant utilizing microbial metabolism and a preparation method thereof, and relates to the technical field of deodorants. The biological deodorant comprises thefollowing main raw materials: a deodorant, nutritional agents, an adsorbent and an adhesive, and the deodorant is frozen active bacteria of deodorizing microorganisms; the nutritional agents and theadhesive jointly form a filler of the biological deodorant particles; the filler is sued for embedding the frozen active bacteria and the adsorbent, and fixing to obtain a granular product; the nutritional agents include general nutritional agents and long-term nutritional agents. According to the invention, various active strains are utilized to metabolize odor molecules, a multi-layer slow-release structure is provided, and the efficient adsorption effect of activated carbon is matched, so that the odor can be removed more quickly, durably, efficiently, conveniently and environmentally friendly.

Description

technical field [0001] The invention relates to the field of deodorants, in particular to a biological deodorant utilizing microbial metabolism and a preparation method thereof. Background technique [0002] Gases such as hydrogen sulfide, ammonia, putrescine, and skatole in feces and urine volatilize to produce odors. These odors often exist in various places, persist, and are difficult to eliminate. Living and working in a smelly environment for a long time is harmful to people's emotions and health; the smell of the cat litter box will make pet cats unwilling to go to the toilet at a fixed point, resulting in disorderly urine; the smell of public places will affect the use, and Detrimental to the appearance of the city. At present, various methods can be used for this kind of odor, such as activated carbon adsorption, aroma masking, frequent cleaning, biological enzymatic hydrolysis, green plant absorption, etc., but these treatment methods have some disadvantages, such ...
