Deodorized fermentation liquor of excrements of livestocks and preparation method thereof

The invention aims to provide a deodorized fermentation liquor of excrements of livestocks and a preparation method thereof. The deodorized fermentation liquor of excrements of livestocks comprises the following components in percentage by weight as follows: 10-18% of cane molasses, 0.5-1.8% of milt paste, 10-20% of starch, 0.6-1.5% of coprophilous lactobacillus, thermophilic streptococcus, saccharomyces cerevisiae, abnormal Hansenula polymorpha and anaerobic cellulose decomposition bacteria seed liquor, and the balance of purified water. The deodorized fermentation liquor of excrements of livestocks provided by the invention has the beneficial effects that under the high temperature anaerobic condition, cellulose is converted into organic acid and alcohol and then into methane and carbon dioxide by means of the anaerobic cellulose decomposition bacteria, so that odor of excrements of livestocks are thoroughly overcome; strains are skillfully combined with special process fermentation to increase organic matt
