Problems solved by technology

[0004] The deodorizing principle of the above deodorants is mainly based on the adsorption of odor molecules or the reaction with odor molecules, and the nitrogen retention effect is very small. With the green and scientific development of animal husbandry, the development and application of compound nitrogen retention deodorants imminent

Embodiment 1

[0022] A nitrogen-preserving and deodorizing agent for the composting of farmed manure, which is obtained by mixing activated biomass supercritical liquefaction residue with carboxymethyl cellulose-coated nano-silver suspension. Wherein, the ratio of biomass supercritical liquefaction residue to carboxymethyl cellulose-coated nano-silver suspension is 50g:4mL.

[0023] Wherein, the preparation method of activated biomass supercritical liquefaction residue comprises the following steps:

[0024] (1) Add pulverized camphor wood chips, ether and sodium carbonate in the high-pressure airtight reactor, the ratio of camphor wood chips, ether and sodium carbonate is 5g: 30mL: 0.03g, carry out liquefaction reaction under nitrogen atmosphere, the liquefaction temperature is 300 ℃, the pressure is 8MPa, and the time is 1h. After the liquefaction is completed, the residue left after filtering off the liquefied oil is the biomass supercritical liquefaction residue;

Abstract

The invention discloses a nitrogen-preserving deodorant applied to composting treatment of livestock manure and application thereof. The nitrogen-preserving deodorant is prepared by mixing activated biomass supercritical liquefaction residue with carboxymethylcellulose-coated nanosilver suspension. When the nitrogen-preserving deodorant is added into the livestock manure, is uniformly stirred and is subjected to high-temperature composting treatment, the volatilization of ammonia gas and the loss of nitrogen in the composting treatment process of the livestock manure can be obviously reduced; the generation of the repugnant substance in the composting process can be reduced; the nitrogen-preserving deodorant is suitably popularized and used in organic fertilizer factories and various farms.

Description

technical field [0001] The invention relates to the purification treatment of the breeding atmospheric environment, in particular to a nitrogen-conserving deodorant for the composting treatment of breeding excrement and its application. Background technique [0002] With the development of large-scale breeding industry in our country, the pollution of poultry and livestock excrement to the surrounding environment is becoming more and more prominent. It is necessary to strengthen the pollution control of poultry and livestock manure in large-scale farms. Livestock manure is rich in a large amount of N and P elements, and it is the best fertilizer resource for crop growth. Therefore, composting livestock manure is the most effective and common treatment method. However, in the process of composting, the loss of nitrogen is relatively serious, and the loss of nitrogen in the initial composting is as high as 70%, which greatly reduces the agricultural value of livestock manure; ...
