Deodorant special for large-scale pig farm and application of deodorant

Abstract

The invention discloses a deodorant special for a large-scale pig farm and application of the deodorant. The deodorant is prepared from a lactobacillus Raman culture, an ovoid bifidobacterium culture,a bifidobacterium longum culture, an intermediate streptococcus culture, a propionibacterium freudenreichii culture, an aspergillus itaconicus culture and a filamentous fungus fungicide; by adding the lactobacillus Raman culture, the ovoid bifidobacterium culture, the bifidobacterium longum culture, the intermediate streptococcus culture, the propionibacterium freudenreichii culture, the aspergillus aconitum culture and the filamentous fungus fungicide into a brown sugar water solution of which the concentration is 6 to 10 percent, the concentration of a lactobacillus Raman strain is up to 10<5> to 10<7> per ml, the concentration of an ovoid bifidobacterium strain is up to 10<6> to 10<8> per ml, the concentration of a bifidobacterium longum strain is up to 10<4> to 10<6> per ml, the concentration of an intermediate streptococcus strain is up to 10<7> to 10<9> per ml, the concentration of a propionibacterium freudenreichii strain is up to 10<4> to 10<8> per ml, the concentration of anaspergillus itaconicus strain is up to 10<4> to 10<7> per ml and the concentration of a filamentous fungus strain is up to 10<6> to 10<9> per ml. According to the deodorant disclosed by the invention,a live pig breeding house is treated through a spraying way, foul gaseous matters such as ammonia gas, hydrogen sulfide, methane, indole, volatile fatty acid, mercaptan can be fundamentally and quickly degraded, and adverse effects on health of live pigs cannot be generated.

Description

technical field [0001] The invention relates to a deodorant, in particular to a special deodorant for large-scale pig farms and its application, and belongs to the technical field of environmental protection. Background technique [0002] With the super-scale development of the pig breeding industry, the pollution of pig excrement to the surrounding environment of the farm is becoming more and more serious. A considerable part of the pig farm emits a very bad smell, which seriously pollutes the living environment of the surrounding residents. So far, 160 volatile components have been identified from feces. More than 80 kinds of nitrogen-containing compounds were also found in feces and urine, 10 of which were related to foul smell. In addition, ammonia, SO2, NO2, amines and amino acid derivatives will be produced during the fermentation process of feces and urine. Although there is little correlation between ammonia and manure odor, a large number of studies have shown tha...

Problems solved by technology

Although there is little correlation between ammonia and manure odor, a large number of studies have shown that high ambient ammonia concentrations can affect animal performance and health, with decreased feed intake and daily gain, increased incidence of pneumonia, and increased sexual maturity. put off

[0003] At present, the main methods used to treat the malodorous gas in pig farms are: absorption method, adsorption method, oxidation method, combustion method, etc., but there are problems such as low treatment efficiency, inconvenient operation, and easy to produce secondary pollution.

Deodorization by microorganisms is a relatively cutting-edge method in recent years. It is mainly divided into two forms: animal in vivo regulation and in vitro regulation. Digestion and absorption, reduce the generation of odor, but the deodorization effect is not obvious, and the microorganisms may have antibiotic resistance genes, disturbing the normal animal microflora

The form of in vitro regulation mainly focuses on the screening of a single deodorizing bacteria strain and the detection of deodorizing effect, while the composition of malodorous gas is complex and the effect is not obvious
