Equipment for emission reduction of poultry and livestock excrement fermentation odor and deodorization method

Abstract

The invention provides equipment for emission reduction of poultry and livestock excrement fermentation odor and a deodorization method. The deodorization equipment comprises a throwing and turning machine device, a pressurization pump machine and a spraying device positioned on the throwing and turning machine device, wherein the spraying device comprises a low-position spraying mechanism and a high-position spraying mechanism; the low-position spraying mechanism comprises a low-position conveying pipeline, a first spray head and a low-position storage tank provided with first deodorization liquid; the first deodorization liquid contains solid-state citric acid, 75 to 85 percent of liquid lactic acid and water; the high-position spraying mechanism comprises a high-position conveying pipeline, a second spray head and a high-position storage tank provided with second deodorization liquid; the second deodorization liquid comprises bacillus pumilus, bacillus nubbi anaerobes, thiobacillusdenitrificans, enterococcus faecalis and short-process nitrifying bacteria. According to the method, a chemical method and a biological method are used for performing chemical neutralization on the released odor and the functional microbial conversion; the goal of reducing the quantity of the odor released into the environment is achieved; the deodorization rate is high.

Description

technical field [0001] The invention relates to the field of harmless treatment of livestock and poultry waste, in particular to equipment and a deodorization method for reducing emission of odor from fermentation of livestock and poultry manure. Background technique [0002] Composting is one of the effective methods for the harmless treatment of livestock and poultry manure, and it is widely used in the treatment of livestock and poultry manure. The biggest problem facing composting is the odor produced by composting, which not only affects the surrounding environment, but also reduces fertility. Therefore, deodorization is an important process of composting. Compost deodorization is mainly achieved through three steps, which are source emission reduction, process emission reduction and terminal treatment. At present, the relevant deodorization process mainly focuses on the two stages of source emission reduction and terminal treatment, and the process of odor process emi...

Problems solved by technology

The three deodorization methods have their own advantages in terms of odor removal. At the same time, they also have certain disadvantages, such as: chemical reaction method: that is, use sterilizing or disinfecting chemicals to kill bacteria or carry out detoxification with pen excrement and urine. Chemical reactions are used to deodorize, such as trichloroisocyanate, strong acid, strong alkali, etc. Although the deodorizing effect is good, it is harmful to humans and animals, and strict procedures must be followed when deodorizing; although biological deodorization methods can be very good Deodorization, but when a variety of bacteria are used together, some bacteria will be difficult to grow due to unsuitable fermentation conditions and insufficient competitiveness during mixed culture. Applied to deodorization work

[0005] In view of the fact that there is currently no process emission reduction equipment and related technical processes for the composting odor of livestock and poultry manure, those skilled in the art hope to combine chemical and biological methods to prepare a composting odor that can achieve odor emission reduction in the concentrated release stage. Equipment and establish relevant process standards to achieve efficient emission reduction of important odor source substances in the composting process, so as to make up for the shortcomings of existing technology processes
