Technical Field

The invention relates to the technical field of garbage treatment, and particularly belongs to a method for treating human food waste by using hermetia illucens.

Background

With the increase of the disposable income of people, the requirements of people on food are higher and higher, various net vegetable distribution services are more and more popular, and food other than dinner is also selected by people with the increase of the disposable income, and accordingly, the food is a large amount of kitchen waste, overdue food, food factory waste, farmer market waste and the like. The classification of waste provides convenience for the disposal of such waste materials, but how to treat them in an efficient, rational, safe and eco-friendly manner remains an issue that has to be addressed in terms of environmental protection. At present, the waste treatment method mainly comprises an incineration method, a compression landfill method and a microbial fermentation method, wherein the former two methods pollute the environment, occupy large land area and have longer time period.

The hermetidae insects are widely distributed in the world, larvae of Hermetia illucens and Ptecticus insects in the hermeticus are saprophagic, and the decayed animal and plant residues, animal wastes and the like are eaten, so that the hermetidae insects have the advantages of large food intake, short life history and the like, can efficiently convert food wastes and complete material circulation. The larvae can survive for 8 days on the water bottom without rotting as aquaculture feed, the excessively fed larvae can not be wasted due to death and rotting, a large amount of labor cost can be saved, and the larvae can also be used as a safe animal protein source. Therefore, the use of Hermetia illucens Hermetia or Ptecticus insects for the disposal of food waste is of great significance for ecological environment construction.

Disclosure of Invention

The invention aims to provide a method for treating human food waste by using Hermetia illucens, which overcomes the defects of the prior art, can finish large-scale treatment of food waste by using Hermetia illucens and Ptecticus insects in Hermetia illucens, has high economic benefit, low production cost and ecological environment friendliness, and can realize the dual targets of ecological civilization construction and economic construction.

In order to solve the problems, the technical scheme adopted by the invention is as follows:

a method of disposing of human food waste with hermetia insects, comprising the steps of:

step one, waste treatment: sorting the food waste, removing inorganic impurities in the food waste, then carrying out solid-liquid separation, and taking a solid waste part for later use;

step two, larva inoculation: crushing and sieving the solid waste obtained after solid-liquid separation in the step one, then flatly paving the solid waste in a culture tank, and then inoculating 2-5-day-old soldier fly larvae into the culture tank;

step three, larva culture: culturing the soldier fly larvae in the culture tank in the step two for 6-10 days in an environment with the ambient temperature of 22-35 ℃ and the air humidity of 60% -90%;

step four, larva separation: using a heating or vibrating sieving method to culture the soldier fly larvae and the residual material which are cultured in the step three and the dung of the soldier fly larvae;

step five, larva processing: the separated stratiomyiid larvae are used as living protein feed to be applied to aquatic products or/and livestock and poultry cultivation, or are used as dry protein feed for the aquatic products or/and livestock and poultry cultivation through drying treatment.

Further, the water content of the solid waste after the solid-liquid separation in the step one is 55-95%.

Further, the particle size of the solid waste crushed in the second step is less than 10 mm.

Further, the thickness of the solid waste laid on the bottom of the culture tank in the second step is less than or equal to 15 cm.

Further, the soldier fly larvae in the second step are larvae of Hermetia illucens or Ptecticus, and the inoculation density of the soldier fly larvae is 80-120g of soldier fly eggs per ton of solid waste.

Further, the heating temperature for separating the stratiomyiid larvae in the fourth step is 40-55 ℃.

And further, naturally cooling the residual materials separated in the fifth step and the excrements of the hermetia illucens larvae, and performing decomposition treatment to obtain the organic fertilizer.

Compared with the prior art, the invention has the following implementation effects:

according to the method for treating the human food waste by using the stratiomyiidae insects, disclosed by the invention, a large amount of food waste can be treated by using the stratiomyiidae insects, the source of the food waste is not required, other auxiliary materials are not required to be added, multiple feeding is not required after larvae are fed once, the method is simple and efficient, the produced larva living bodies can be used as aquatic products and ornamental fish feed and can be used as animal protein additives after being preserved in a water body for a long time or being heated and crushed by microwaves, excrement and residual materials can be used as organic fertilizers, and the labor cost is saved while the high-efficiency large-amount recycling of the food waste is realized.

The method for treating the human food waste by using the stratiomyiidae insects has the advantages of high economic benefit, low production cost and environmental friendliness, and can realize double targets of ecological civilization construction and economic construction.
