Problems solved by technology

At present, waste treatment methods mainly include incineration, compressed landfill, and microbial fermentation. The former two pollute the environment and occupy a large area of ​​land, while the latter takes a long time.

Embodiment 1

[0023] A method of utilizing Soldieridae insects to dispose of human food waste according to the present invention comprises the following steps:

[0024] (1) Take 180g of moist wheat bran (squeezed by hand without dripping water) and put it in a 300mL PVC container, and sprinkle 80-120g of freshly collected eggs of Hermetia or Ptecticus on the surface according to the treatment requirements , and then sprinkle 0.5cm thick dry wheat bran on the surface, and cultivate it for 7-9 days at 30° C. RH=60%, to obtain soldier fly larvae for treatment;

[0025] (2) Sorting the food waste, removing the inorganic impurities and then separating the solid from the liquid, keeping the water content at 55%-95%, and taking the solid waste for later use;

[0026] (3) Crush 1 ton of solid waste after solid-liquid separation to a particle size of less than 10 mm, and spread it in the breeding tank after sieving. The thickness of the solid waste laid on the bottom of the breeding tank is 15 cm, a...

Embodiment 2

[0032] The materials and preparation process are basically the same as in Example 1, except that 120 g of soldier fly larvae hatched from soldier fly eggs are inserted into the breeding tank for each ton of solid waste.

[0033] After testing, according to the method of this embodiment, 320kg of larvae can be obtained for every ton of pretreated kitchen waste, and 487kg of organic fertilizer (wherein 385kg of worm sand and 102kg of unprocessed kitchen waste).

Embodiment 3

[0035] The materials and preparation process are basically the same as those in Example 1, except that the solid waste with a thickness of 5 cm is tiled first in the culture tank, and then 80 g of soldier fly larvae hatched from soldier fly eggs are inserted into the culture tank, and the cultivated On the third and fourth days, 5 cm thick solid waste was added respectively.

[0036] After testing, according to the method of the present embodiment, 210kg of larvae can be obtained for every ton of pretreated kitchen waste, and 448kg of organic fertilizer (247kg of worm sand and 201kg of unprocessed kitchen waste).

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.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a method for disposing of human food waste by using Soldieridae insects. Background technique [0002] With the increase of people's disposable income, people's requirements for food are getting higher and higher, and various clean food delivery services are becoming more and more popular. What follows is a large amount of kitchen waste, expired food, waste from food factories and waste from farmers' markets. Garbage classification provides convenience for the disposal of these wastes, but how to deal with these wastes in an efficient, reasonable, safe, and eco-friendly way is still a problem that environmental protection has to find a way to solve. At present, waste treatment methods mainly include incineration, compressed landfill, and microbial fermentation. The former two pollute the environment and occupy a large area of ​​land, while the latter takes a long time. ...
