The invention discloses a livestock manure liquid innocent treatment and intelligent fertilizer preparation integrated system, which integrates a manure liquid fermentation system, a fertilizer preparation system and an odor control system, realizes innocent treatment by using a high-temperature composting method, sequentially comprises the steps of gas pumping, primary removal, enrichment, combustion, injection and re-removal, adsorbs water and carbon dioxide by using an adsorption part, and realizes intelligent fertilizer preparation by using a high-temperature composting method. According to the method, the concentration of the odor is enriched, the odor can be repeatedly mixed with oxygen after being pressurized and then combusted, ammonia gas containing the odor is converted into odorless nitrogen, sulfur dioxide is generated after hydrogen sulfide is sufficiently combusted and is adsorbed by the removal part, so that the ammonia gas, the hydrogen sulfide, methane and the like in the fermentation tank ar
