Problems solved by technology

However, the current composting project has always had problems such as serious odor pollution.
A large amount of malodorous gas will be produced in the process of aerobic composting, and the resulting odor pollution problem has become an obstacle to the development of aerobic composting technology. At the same time, the odor can stimulate the human olfactory organs, generally cause unpleasantness or disgust, and damage the human body. healthy

Embodiment 1

[0043] The deodorizing liquid is used in the biological filter tower of the deodorizing system of the composting project.

[0044] The production method of deodorant liquid comprises the following steps:

[0045] The production of compound microbial bacterial agent, the steps are as follows:

[0046] (1) Seed solution culture: Thiobacillus thioparus, Pseudoxanthomonas, Candida utilis and Bacillus sphaericus preserved on the slant Inoculate them in the corresponding liquid medium respectively, the volume of liquid in the triangular flask is 40%, and culture in shake flask at 28°C and 180r / min for 2 days, the number of bacteria reaches 1×10 8 cfu / ml, the seed liquids of 4 kinds of strains were obtained, respectively, the seed liquids of Thiobacillus thiaphulens, the seed liquids of Pseudomonas pseudoxanthomonas, the seed liquids of Candida utilis and the seed liquids of Bacillus sphaericus. The components of the liquid medium are: ① Medium for Candida utilis: 20.0 g of sucrose...

Embodiment 2

[0052] Example 2 The deodorizing liquid is used for odor control in the aerobic high-temperature composting process of chicken manure and mushroom dregs in a composting plant.

[0053] The production of compound microbial bacterial agent, the steps are as follows:

[0054] (1) Seed solution culture: Thiobacillus thioparus, Pseudoxanthomonas, Candida utilis and Bacillus sphaericus preserved on the slant Inoculate them in the corresponding liquid culture medium respectively, the liquid volume in the Erlenmeyer flask is 40%, 30°C, 150r / min shake flask culture for 3 days, the number of bacteria reaches 1×10 8 cfu / ml, the seed liquids of 4 kinds of strains were prepared, namely the seed liquids of Thiobacillus thiaphulens, the seed liquids of Pseudomonas pseudoxanthomonas, the seed liquids of Candida utilis and the seed liquids of Bacillus sphaericus. The components of the liquid medium are: ① Medium for Candida utilis: 25.0 g of sucrose, NaNO 3 5.0g, K 2 HPO 4 1.0g, KCl0.5g, M...

Embodiment 3

[0060] Example 3 The deodorizing liquid is used for odor control in the secondary fermentation (compost aging) process.

[0061] The production method of deodorant liquid comprises the following steps:

[0062]The production of compound microbial bacterial agent, the steps are as follows:

[0063] (1) Seed solution culture: Thiobacillus thioparus, Pseudoxanthomonas, Candida utilis and Bacillus sphaericus preserved on the slant Inoculate them in the corresponding liquid culture medium respectively, the liquid volume in the Erlenmeyer flask is 40%, 28°C, 150r / min shake flask culture for 3 days, the number of bacteria reaches 1×10 8 cfu / ml, the seed liquids of 4 kinds of strains were obtained, respectively, the seed liquids of Thiobacillus thiaphulens, the seed liquids of Pseudomonas pseudoxanthomonas, the seed liquids of Candida utilis and the seed liquids of Bacillus sphaericus. The components of the liquid medium are: ① Medium for Candida utilis: 22.0 g of sucrose, NaNO 3 4...

Abstract

The invention discloses deodorant liquid for high-temperature compost and an application and use method thereof. The deodorant liquid is formed by mixing the following components in percentage by mass: 80-90% of compound microbial agent, 9.5-19.9% of plant extraction liquid and 0.1-0.5% of alkyl glycoside. The use method comprises the following steps: in a biological filter tower, adding 1-5kg of deodorant liquid into each ton of circulating water, and mixing uniformly, wherein the deodorant liquid degrades the odor along with a spray process of the circulating water, and meanwhile, the deodorant liquid is attached to the biological filter material of the biological filter tower to form a biological film to degrade odor; or diluting the deodorant liquid, spraying the diluted deodorant liquid into the compost material, and stirring uniformly. The use method also comprises a step of spraying the diluted deodorant liquid into the surface of the aged compost material and the ambient air. The deodorant liquid disclosed by the invention is simple to prepare, realizes a remarkable deodorant effect, prevents secondary pollution, can be applied to a biological filter tower of an odor treatment system of a compost engineering, and also can be applied to the odor control and degradation of the one-time compost fermentation process and the compost aging process.

Description

technical field [0001] The invention relates to the field of odor treatment, in particular to a deodorizing liquid suitable for high-temperature composting and its application and usage method. Background technique [0002] Aerobic high-temperature composting is an important way to realize the reduction, harmlessness and recycling of organic solid waste. The products formed after composting are rich in humus and certain N, P, and K, which can be used as good soil conditioners and organic fertilizer. However, the current composting project has always had problems such as serious odor pollution. A large amount of malodorous gas will be produced in the process of aerobic composting, and the resulting odor pollution problem has become an obstacle to the development of aerobic composting technology. At the same time, the odor can stimulate the human olfactory organs, generally cause unpleasantness or disgust, and damage the human body. healthy. Therefore, composting projects m...
