Description

TECHNICAL FIELD

[0001] The present application relates to the field of livestock breeding waste fermentation, and in particular, relates to a livestock breeding waste anaerobic fermentation harmless treatment device and method. BACKGROUND

[0002] Livestock farming is a production department that uses the physiological functions of animals such as domesticated animals or wild animals such as deer, musk deer, foxes, minks, otters, and quails to obtain animal products or work animals. While earning income, many people ignore the disposal of livestock waste, which has led to a deteriorating environment and even the spread of some diseases and viruses, causing great harm. In livestock breeding, animals produce a large amount of excrement, which can be used as fertilizer and other materials after fermentation treatment, and can be used for biogas. Biogas fermentation, also known as anaerobic digestion or anaerobic fermentation, is a process in which organic matter such as human and animal excrement, straw, and weeds is decomposed and metabolized by various microorganisms under certain moisture, temperature, and anaerobic conditions, ultimately forming a flammable gas mixture of methane and carbon dioxide. The biogas fermentation system is based on the principle of biogas fermentation and aims to produce energy, ultimately achieving the comprehensive utilization of biogas, biogas slurry, and biogas residue.

[0003] At present, when livestock breeding waste is subjected to anaerobic fermentation, the waste and microbial inoculum need to be simultaneously put into the fermentation tank for mixing reaction and fermentation treatment. However, workers generally first put a large amount of waste into the fermentation tank and then continue to put in the appropriate amount of microbial inoculum, so the waste and microbial inoculum will accumulate together and cannot be quickly mixed together for reaction and fermentation.
