Ecological circulation system for recycling and harmless treatment of livestock and poultry feces

Abstract

The invention discloses an ecological circulatory system for recycling and harmless treatment of livestock and poultry feces. According to the system, firstly, plant lactic acid bacteria are utilized to treat the original livestock and poultry feces, residues of harmful substances in the original livestock and poultry feces are removed, and harmless livestock and poultry feces are obtained; secondly, hermetia illucens eggs are added into the obtained harmless livestock and poultry feces, and hermetia illucens larvae are cultured to obtain hermetia illucens larvae, puparium and larva dungs, wherein the hermetia illucens larvae serve as breeding feed, puparium is prepared into chitin, and the larva dungs serve as organic fertilizer. According to the ecological circulatory system for the recycling and harmless treatment of the livestock and poultry feces, the mode of using the plant lactic acid bacteria to deodorize the livestock and poultry feces at first is put forward for the first time, the residues of the harmful substances in the feces are degraded, the obtained harmless livestock and poultry feces are utilized to culture hermetia illucens, and in this way, the obtained hermetia illucens larvae, puparium and larva dungs are all harmless products.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to an ecological cycle system for resourceful and harmless treatment of livestock and poultry manure. Background technique [0002] At present, in the aquaculture industry of our country, it is common to add additives such as antibiotics and even hormones to the feed in order to reduce the diseases of livestock and poultry during the aquaculture process. Therefore, the meat, poultry and eggs produced The harmful indicators in the food exceed the standard, seriously affecting the safety of food. Simultaneously, the feces of these livestock and poultry also contain many harmful substances, and the practical value of the black soldier flies produced with such feces also has safety problems. Fertilizing fields with such manure also pollutes the soil. After the polluted soil is used for planting crops, the agricultural products produced also have food saf...
