Abstract

The invention relates to the technical field of garbage treatment, and particularly discloses a method for treating human food waste by using stratiomyidae insects. The method comprises the followingsteps of step 1, sorting the food waste, removing inorganic impurities in the food waste, and carrying out solid-liquid separation; step 2, crushing and sieving the solid waste material after solid-liquid separation, then flatly laying the crushed and sieved solid waste material in a breeding tank, and then inoculating stratiomyiid larvae (Hermetia or Ptecticus) of 2-5 days old into the breeding tank; step 3, culturing the stratiomyiid larvae in the breeding tank for 6-10 days under the environment with the environment temperature of 22-35 DEG C and the air humidity of 60%-90%; step 4, using aheating or vibration sieving method to sieve the stratiomyiid larvae, residual materials and the stratiomyiid larvae excrement; and step 5, serving the separated stratiomyiid larvae as living proteinfeed to be applied to aquaculture or/and livestock and poultry breeding. The defects in the prior art are overcome, a large amount of food waste can be treated by using Hermetia insects, the economicbenefit is high, the production cost is low, and the double goals of ecological civilization construction and economic construction can be achieved.

Example Embodiment

[0022] Example 1
[0023] A method for disposing of human food wastes by utilizing the waterfly insects of the present invention, comprising the following steps:
[0024] (1) Take 180g of moist wheat bran (squeeze by hand without dripping water) and put it in a 300mL PVC container, and sprinkle 80-120g of newly collected eggs of Hermetia or Ptecticus on the surface according to the processing needs. , and then sprinkle 0.5cm thick dry wheat bran on the surface, and cultivate at 30°C RH=60% for 7-9 days to obtain water horsefly larvae for treatment;
[0025] (2) Sort the food waste, remove the inorganic impurities and then carry out solid-liquid separation, keep the water content at 55%-95%, and take the solid waste part for use;
[0026] (3) pulverize the solid waste after 1 ton of solid-liquid separation to a particle size of less than 10mm, lay it flat in the breeding tank after sieving, and the thickness of the solid waste spread on the bottom of the breeding tank is 15cm, and then insert into the breeding tank 80g soldier fly larvae hatched from soldier fly eggs;
[0027] (4) Cultivate the water horsefly larvae in the culturing tank for 6-10 days at an ambient temperature of 22-35°C and an air humidity of 60%-90%;
[0028] (5) use the method of heating or vibrating sieving to pass through the water horsefly larvae and residual material and water horse fly larvae excrement cultivated in step 3, wherein use the method of heating or vibrating sieving to pass through the water horsefly larvae and residual material and water cultivated in step 3 feces of horsefly larvae;
[0029] (6) The separated water flies larvae are used as live protein feeds in aquaculture or/and livestock and poultry breeding, or as dry protein feeds for aquatic products or/and livestock and poultry breeding through drying treatment, the separated residues and water flies The larvae feces are naturally cooled and then over-decomposed to obtain organic fertilizer.
[0030] After testing, according to the method of this embodiment, 240kg of larvae and 471kg of organic fertilizer (including 283kg of insect sand and 188kg of untreated kitchen waste) can be obtained for each ton of pretreated kitchen waste.

Example Embodiment

[0031] Example 2
[0032] The materials and preparation process are basically the same as those of Example 1, except that the cultivating tank of each ton of solid waste is connected with 120 g of water horse fly larvae hatched from the water horse fly eggs.
[0033] After testing, according to the method of this embodiment, 320kg of larvae and 487kg of organic fertilizer (including 385kg of insect sand and 102kg of untreated kitchen waste) can be obtained for each ton of pretreated kitchen waste.

Example Embodiment

[0034] Example 3
[0035] The material and preparation technique of Example 1 are basically the same, and the only difference is that at first the solid waste of 5cm thick is laid flat in the culturing tank, and then the soldier fly larvae hatched from 80g of water horsefly eggs are inserted into the culturing tank, and the cultured On the third and fourth days, 5 cm thick solid waste was added respectively.
[0036] After testing, according to the method of this embodiment, 210kg of larvae and 448kg of organic fertilizer (including 247kg of insect sand and 201kg of untreated kitchen waste) can be obtained for each ton of pretreated kitchen waste.
