Abstract

The invention relates to a harmless amino acid-containing aqueous solution of dead livestock and poultry, which includes the following raw material components: raw meal, concentrated sulfuric acid, water, iron ammonia complex, hydrogen peroxide, formic acid and formaldehyde. Prepared by reaction of ferrous acetate, urea, ammonium carbonate and water. The invention has the advantages of high amino acid content, low odor, no waste water discharge, and reusable water produced by other production processes.

Description

technical field [0001] The invention relates to a harmless amino acid-containing aqueous solution of dead livestock and poultry and a preparation method thereof. Background technique [0002] With the rise of the harmless treatment industry of dead livestock and poultry, the research on the harmless treatment process of dead livestock and poultry has gradually become a hot spot for researchers. The mainstream process for the harmless treatment of sick and dead livestock and poultry is the high-temperature drying treatment process. This process has problems such as high energy consumption, large amount of wastewater, difficult treatment of wastewater, and difficulty in comprehensive utilization of wastewater, which leads to the harmless treatment of existing sick and dead livestock and poultry. The problem of a large amount of waste water is generated, and the problem of waste water treatment in the process of harmless treatment of sick and dead livestock and poultry needs to...
