Embodiment 1

[0022] Embodiment 1. The preparation method of the composite deodorant of the present embodiment is as follows:

[0023] 1) Take ordinary white ceramic tiles, crush them into a diameter of 1-2mm, wash them with clean water, and dry them at a constant temperature of 110°C for 2 hours, then set aside;

[0024] 2) After the Candida tripicalis CCW-Y3 strain (Candida tripicalis CCW-Y3) was activated on the slant, it was inserted into 2L liquid expansion medium, divided into 4 bottles, and placed on a shaker at 220r / min, at 30 Cultivate at constant temperature for 4 days. Centrifuge at 8000rpm for 25min to harvest bacterial cells and weigh them, transfer and suspend all of them into 80mL basic medium, the number of bacteria is not less than 1×10 10 A / ml order of magnitude, spare;

[0025] 3) Mix the rice bran and the above-mentioned ceramic granules uniformly at a ratio of 1:10, take different weights of ceramic granules and mix them well with different volumes of microbial bacter...

Embodiment 2

[0032] Example 2: Different from Example 1, the carrier of the composite deodorant is natural clinoptilolite from Jinyun, Zhejiang, and the particle size and treatment method are the same as in Example 1. The microorganism on the composite deodorant carrier is Saccharomyces cerevisiae, the cultivation and harvesting method of the bacterial liquid is the same as that of Example 1, and the bacterial cells are 5.65g bacterial cells / kg carrier. Adopt 6 plastic barrels, wherein 3 are as contrast, only have chicken manure, and other 3 are as processing, except chicken manure, also will be housed the dish of composite deodorant on the small iron hook of rubber stopper inside the barrel. All the other are identical with embodiment 1. See Table 2 for the treatment effect.

Embodiment 3

[0035] Embodiment 3: Different from Example 1, the microorganisms on the composite deodorant carrier are the mixed bacterial liquid of Candida tropicalis CCW-Y3 bacterial strain (Candida tripicalis CCW-Y3) and Saccharomyces cerevisiae, and the two kinds of microorganisms are carried out respectively Example 1 carried out the cultivation and harvesting methods of the bacterial liquid, and mixed them at a ratio of 1:1. The total bacterial cells are 6.05g bacterial cells / kg carrier. Dress fresh cow dung 2000g in the plastic bucket, all the other are all identical with embodiment 1. See Table 3 for the treatment effect.

Abstract

The invention discloses a microorganism and porous material composite deodorant and the preparing method, wherein the microorganism is candida tropicalis CCW-Y3 bacterial strain and Saccharomyces cerevisiae with cellular material as the carrier, the mass ratio of microorganism and porous material carrier is 4-6:1000. The invention has the microorganism with high deodorant property on the porous material, which avoids the absorption saturation of the carrier by absorbing the bad smell molecule to the surface with the porous carrier with high deodorant property and disintegrating the bad smell molecule with the microorganism absorbed on the carrier, wherein the composite deodorant is arranged in the ventilating flat dish, and is hanged in the upper space of animal house, breeding house or faecal, the material of the dish is wood, iron or bamboo ware.

Description

technical field [0001] The invention provides a deodorant and its preparation and deodorization method, which relates to a physical adsorption-microbial degradation combined deodorization technology of odor, especially an efficient deodorization technology method and device for odor in livestock and poultry farms . Background technique [0002] With the rapid development of livestock and poultry breeding production, especially the development of large-scale breeding, a large amount of livestock and poultry waste is produced, which has caused the contradiction between the development of livestock and poultry industry and environmental pollution to become increasingly prominent. The pollution of livestock and poultry breeding has become the current continuous It is the third largest source of pollution after industrial pollution and domestic garbage pollution. The most important pollutants in the livestock and poultry breeding industry are feces and urine and the odor they pr...
