Method for performing pig manure resource treatment by utilizing hermetia illucens

Abstract

The invention discloses a method for performing pig manure resource treatment by utilizing hermetia illucens, belonging to the field of solid waste treatment. The method comprises the following technological steps: (1) mixing pig manure with oilseed meals so as to adjust the water content of pig manure; (2) performing primary fermentation to the mixture by adopting bacillus subtilis, and further fermenting with brewer yeast; (3) feeding black soldier fly Hermetia illucens for raising according to a certain proportion; and (4) after the raising period is finished, collecting the black soldier fly Hermetia illucens and ooze. The method is simple to operate, and fast for pig manure resource treatment process. After conducting the above technological treatment, pig manure and oil seed meals are converted into black soldier fly Hermetia illucens and excreta ooze thereof, the residual tetracycline antibiotics (oxytetracycline, chlorotetracycline and tetracycline) in the pig manure cannot be detected in the black soldier fly Hermetia illucens and ooze. The method not only can solve the problems of pig manure environment pollution, the antibiotics residues, human health damage and the like, but also can provide black soldier fly Hermetia illucens and ooze with rich nutrients for feed and fertilizer industries.

Description

technical field

[0001] The invention belongs to the field of solid waste treatment, in particular to a method for resourceful treatment of pig manure. Background technique

[0002] With the development of animal husbandry production in the direction of modernization, intensification and scale, veterinary drugs play a significant role in reducing animal morbidity and mortality and promoting animal growth. According to reports, about 70% of the total antibiotic production in the world is used in animal husbandry, especially the consumption of tetracycline antibiotics accounts for half of the total antibiotic consumption. A large number of studies have shown that after antibiotics enter the animal body, about 60% to 90% are excreted with the animal feces in the form of drug prototype or primary metabolites. According to reports, in 2010, the discharge of livestock and poultry manure in the country reached 4.5 billion tons. After these manures were applied to farmland as organi...

Examples

Embodiment 1

[0019] Mix 5kg of fresh pig manure and rapeseed meal according to the mass ratio of about 1:1, so that the mass percentage of the water content of the mixture reaches 40%; Inoculate the activated Bacillus subtilis (Bacillus subtilis) culture solution at a ratio of (v / w), ferment at 37°C for 1 day; Proportionally inoculate the activated Saccharomyces cerevisiae (Saccharomycescerevisiae) culture solution, and continue to ferment at 28°C for 5 days; add 1kg of the fermented mixture to 1kg of black soldier fly larvae (Hermetia illucens L.), and raise them at 27°C. China will appropriately add fermentation products depending on the feeding situation of the black soldier fly larvae; the feeding process lasts for about 10 days, when the color of the black soldier fly larvae darkens and the feeding speed slows down, collect the black soldier fly larvae and insect sand. Black soldier fly larvae, insect sand and unfinished feed can be used for feed and fertilizer production respectively...

Embodiment 2

[0021] Mix 5kg of fresh pig manure with cottonseed meal at a mass ratio of about 1.8:1 so that the mass percent of the moisture content of the mixture reaches 50%; v / w) to inoculate the activated Bacillus subtilis (Bacillus subtilis) culture solution, ferment at 37°C for 3 days; then sterilize at 121°C for 15 minutes, cool to room temperature according to the ratio of 10% (v / w) Inoculate the activated Saccharomyces cerevisiae (Saccharomycescerevisiae) culture solution, and continue to ferment for 2 days at 28°C; add 2.5kg of the fermented mixture to 0.5kg of black soldier fly larvae (Hermetia illucens L.), and raise them at 27°C. During the process, fermented products are appropriately added depending on the feeding situation of the black soldier fly larvae; the feeding process lasts for about 10 days, and when the black soldier fly larvae become darker in color and their feeding speed slows down, collect the black soldier fly larvae and insect sand. Black soldier fly larvae, ...

[0023] After mixing 10kg of fresh pig manure and soybean meal according to the mass ratio of about 6.5:1, the mass percentage of the moisture content of the mixture reaches 70%; v / w) to inoculate the activated Bacillus subtilis (Bacillus subtilis) culture solution, ferment at 37°C for 2 days; then sterilize at 121°C for 15 minutes, cool to room temperature according to the ratio of 8% (v / w) Inoculate the activated Saccharomyces cerevisiae (Saccharomycescerevisiae) culture solution, and continue to ferment at 28°C for 3 days; add 1kg of the fermented mixture to 0.5kg of black soldier fly larvae (Hermetia illucens L.), and raise them at 27°C. China will appropriately add fermentation products depending on the feeding situation of the black soldier fly larvae; the feeding process lasts for about 10 days, when the color of the black soldier fly larvae darkens and the feeding speed slows down, collect the black soldier fly larvae and insect sand.
