Embodiment 1

[0024] A deodorizing composition for the treatment of farmed excrement, comprising the following components in mass percent:

[0025] Activated biomass supercritical liquefaction residue 55%, activated carbon 15%, bran 15%, calcium acetate 15%.

[0026] Wherein, the preparation method of activated biomass supercritical liquefaction residue comprises the following steps:

[0027] (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 deodorization composition used for processing breeding dung and an application thereof. The deodorization composition is prepared from, by mass, 40%-55% of activated biomass supercritical liquidation residue, 15%-25% of activated carbon, 10%-15% of bran and 10%-15% of organic calcium. The deodorization composition can reduce the production of repugnant substances in an animal dung compost process, and the composition is suitable for usage and popularization in organic fertilizer factories and all large farms.

Description

technical field [0001] The invention relates to purification treatment of breeding atmospheric environment, in particular to a deodorizing composition for treating breeding manure and its application. Background technique [0002] With the development of my country's large-scale breeding industry, the pollution problems brought by farms to the surrounding environment have become more prominent. The odor emitted by livestock and poultry is the same as the manure that causes environmental problems. The volatile odor components contained in the excrement of livestock and poultry itself or released during storage include amines, sulfur-containing compounds, nitrogen-containing compounds, etc. These harmful gases are serious hazards, which will reduce the immunity of livestock to diseases, increase the cost of breeding industry, and affect the health of farmers and surrounding residents. In addition, malodorous gases entering the atmosphere may also form acid rain, causing serio...
