There are mainly two problems: on the one hand, the content of available carbohydrate and protein of the separated solid residue is low, and the proportion of the available carbohydrate and protein does not meet the requirement of the fast growth of the hermetia illucens, so that the yield of the hermetia illucens is low in a certain period, and the proportion of nutritional ingredients in a complex component system of the wet garbage solid residue does not meet the actual growth requirement of the hermetia illucens; on the other hand, wet garbage sorting solid slag contains more fibers, fabrics and the like, cannot be directly utilized by hermetia illucens, and is easy to cause agglomeration, so that the separation effect of end worm and excrement is poor.

The raw materials used in the following examples of the invention are all obtained by treatment in a kitchen waste terminal disposal facility in Shanghai city.
The invention provides a method for culturing hermetia illucens by utilizing wet garbage to sort and fix residues, which comprises the following steps: the method mainly comprises 5 key units, namely a raw material pretreatment unit, a raw material compounding unit, a hermetia illucens egg hatching unit, a hermetia illucens larva breeding unit and a hermetia illucens manure screening unit.
Firstly, raw material pretreatment: heating wet garbage sorting solid slag at 70-80 ℃ for 15-25min, and controlling the particle size of the materials below 4mm by using a grinding crusher; in theory, the same effect can be achieved by heating the wet garbage sorting solid slag under the above conditions, but in the following examples of the present invention, the heating temperature is preferably controlled at 75 ℃ and the time is preferably controlled at 20min for the sake of parameter difference, which results in failure to perform the singleness comparison. Similarly, the grain diameter is controlled to be 3mm.
Secondly, compounding cultivation raw materials: the material for raising the hermetia illucens is required to be controlled by three factors, (1) the water content: the water content of the culture raw materials is controlled to be 70-78%, the water content of the crushed wheat bran can be reduced, and the water content of the kitchen waste slurry is improved by utilizing the slurry of the kitchen waste slurry; preferably 75%; (2) a nutrient component: the nutrient component is non-fibrous carbohydrate content and protein content up to 40% or more of dry weight, non-fibrous carbohydrate=1- (neutral washing fiber + crude protein + crude fat + crude ash); (3) the ratio of the nutrient components is as follows: the non-fibrous carbohydrate content is controlled to be 1-2 times the protein content. In the wet garbage sorting solid slag, the content of non-fibrous carbohydrate is 10-20% and the content of protein is 20-30%, so that 10-20% of non-fibrous carbohydrate can be added to control the dosage relationship between the non-fibrous carbohydrate and protein, such as oat bran, brown rice waste and the like;
thirdly, an insect egg hatching stage: strictly controlling the temperature of the growing environment to 28-32 ℃ and the humidity to be less than 80%, and laying eggs above the hatching matrix according to the ratio of 1g eggs to 150g matrix by using the nutrients obtained in the second step as the hatching matrix, wherein the hatching time is 2-3 days, so as to obtain the 1-year-old black soldier fly larvae; in theory, the temperature and humidity are controlled to meet the cultivation conditions within a limited range, but in order to avoid that the parameter difference leads to the failure of the singleness comparison, the temperature is preferably controlled to 30 ℃ and the humidity is preferably controlled to 75% in the incubation stage according to the following examples of the invention.
Fourthly, raising hermetia illucens: the breeding stage is divided into 1-3-year-old larvae and 3-to-5-year-old larvae. The breeding stage of the 1-3-year-old insects is as follows: and (3) uniformly pouring the residual matrixes in the step (III) into a 1# cultivation device, adding the fresh cultivation raw materials prepared in the step (II) into the rest part to complement, controlling the thickness of the pavement of the nutrients to be 5-8cm, and keeping the mass ratio of the eggs to the nutrients to be 1:1500 for 3 days to obtain the black soldier fly 3-year larva. The temperature of the cultivation environment is controlled at 26-30 ℃, the humidity is less than 80%, the 1# cultivation device is provided with a breathable bag made of terylene, and the gaps of terylene are 60-80 meshes. The 3-5-year larva breeding stage is as follows: pouring the 1# cultivating box into a 2# cultivating device, supplementing the fresh cultivating raw material prepared in the second step, controlling the spreading thickness of the raw material to be 5-8cm, controlling the mass ratio of eggs to materials to be 1:15000, cultivating for 4 days to obtain 5-year old insects, controlling the environmental temperature to be 26-30 ℃, controlling the humidity to be less than 80%, and selecting a breathable bag made of terylene in the 2# cultivating device, wherein the gaps of the terylene are 60-80 meshes. Theoretically, the same effect can be achieved as long as the cultivation is performed under the conditions, but in order to ensure that the parameter difference can not be singly compared, in the following embodiment of the invention, the temperature of the cultivation environment is controlled at 30 ℃ and the humidity is controlled at 75% in the 3-year larva cultivation stage of the hermetia illucens; and in the breeding stage of the black soldier fly 5-year larvae, the temperature of the breeding environment is controlled at 30 ℃, and the humidity is controlled at 75%. In the cultivation process of the hermetia illucens in the following embodiment, terylene air-permeable bags with 60-80 meshes are selected as the cultivation devices.
And step 5, the 2# cultivation box reaching the 5-instar insect stage in the step four is separated by utilizing a two-stage rotary screen and a winnowing device to separate the insect manure. Particularly, the two-stage vibrating screens are respectively used for screening and selecting the undersize to obtain the insect manure, the undersize fresh insects and fiber impurities are obtained by utilizing the 8mm particle size to screen the undersize, and the undersize is incorporated into the insect manure; and (3) separating the undersize with the particle size of 8mm by utilizing specific gravity winnowing to obtain heavy fresh insects and light fiber impurities.
