Enzyme deodorant, and preparation method and applications thereof

Abstract

The invention discloses an enzyme deodorant, and more specifically provides a high-efficiency enzyme deodorant used for livestock and poultry excrement. Problems of the prior art that biological deodorant raw material extraction technology is complex, cost is high, and deodorant effect is achieved slowly, are solved. The enzyme deodorant comprises a horseradish peroxidase donator, an electron acceptor, and an adsorbent; the horseradish peroxidase donator can be selected from horseradish peroxidase and / or horseradish plant materials; the electron acceptor can be selected from peroxides such as calcium peroxide, or sodium percarbonate, or a mixture of calcium peroxide and sodium percarbonate; and the adsorbent can be selected from dried wheat bran, rice bran, wood chip, straw powder, and a mixture of dried wheat bran, rice bran, wood chip, and straw powder. The invention also provides a preparation method of the enzyme deodorant, and applications of the enzyme deodorant in livestock and poultry excrement deodorization treatment. The raw materials, including the horseradish peroxidase donator, of the enzyme deodorant are easily available, are convenient for processing and preparation, and are low in cost; the enzyme deodorant is specifically used for livestock and poultry excrement deodorization treatment; deodorization effect is achieved quickly; and no secondary pollution is caused.

Description

technical field [0001] The invention relates to a deodorant, in particular to an enzyme agent for deodorizing livestock and poultry manure, a preparation method and application thereof, and belongs to the field of environmental bioengineering. Background technique [0002] The output value of my country's livestock and poultry breeding industry has now accounted for 34% of the total agricultural output value. In some fast-growing areas, the income of the breeding industry has accounted for more than 40% of farmers' income. While the development of the breeding industry has improved people's living standards and ensured a stable supply of livestock and poultry products in urban and rural areas, it has also caused increasingly serious environmental problems. The manure produced by the breeding industry not only pollutes water bodies and soil, but also causes serious odor pollution to the air in surrounding areas due to the decomposition of livestock and poultry manure. Odor is...

Problems solved by technology

[0003] At present, livestock and poultry manure deodorants are mainly divided into two categories: chemical deodorants and biological deodorants. Although chemical deodorants have the characteristics of strong pertinence and quick effect, because of their singleness in the removal of malodorous gases, When it encounters complex malodorous gas components, its deodorizing effect will be greatly reduced, and at the same time, the cost of use is high, and it is easy to cause secondary pollution to the environment. The application range of chemical deodorants is small

Biological deodorants mainly include microbial agents made of plant extracts or compound preparations mixed with plant extracts or essences and microbial agents. Among them, plant extracts are mostly extracted from expensive materials such as Chinese herbal medicines. The process is complicated and the cost is high; while the deodorizing effect of the microbial agent is slow, it is difficult to play a role in a short time. At the same time, whether the microorganisms inserted in the agent can grow in pig manure is also a factor affecting the deodorizing effect
