Problems solved by technology

However, food waste is rich in a large amount of oil. If the food waste is directly used to feed fly maggots and earthworms, it will often cause hypoxia and acidification of the culture medium due to the rich oil in the breeding qualification, resulting in the death of fly maggots and earthworms. Growth or even death, resulting in breeding failure

Embodiment 1

[0022] A method for resource utilization of kitchen waste, comprising the following steps:

[0023] 1) Collection and sorting of food waste: add microbial agent M to the tableware waste when collecting food waste, then remove metal objects and large inorganic particles from the food waste, and centrifuge the cleaned food waste Separation to obtain solid food waste and liquid food waste;

[0024] 2) Food waste treatment: Put solid food waste, ammonified cassava residue and fruit peels in a pulverizer to pulverize, add microbial agent M, and ferment for 5 to 7 days to obtain material A; Garbage and crushed red duckweed are mixed evenly, microbial agent N is added, fermented for 2 to 3 days, and material B is obtained;

[0025] 3) Fly maggot culture: mix material A, material B and fish meal with a mass ratio of 5-10:2-3:1-2 evenly to obtain material C, and lay material C on an egg-collecting plate to collect fly eggs. Adding material A to the maggot breeding pool, adding fly eg...

Abstract

The invention discLoses a method for recycLing kitchen waste, which comprises the foLLowing steps: 1) kitchen waste coLLection and sorting; 2) kitchen waste treatment: the soLid kitchen waste, ammoniated cassava residue and fruit skin are pLaced in a puLverizer, a microbiaL agent M is added, and fermentation is carries out for 5-7 days to obtain a materiaL A; Liquid kitchen waste and red puLverized materiaL are uniformLy mixed, a microbiaL agent N is added, and fermentation is carried out for 2-3 days to obtain a materiaL B; 3) fLy maggots cuLture: the materiaL A, the materiaL B and fish meaLwith a mass ratio of 5-10, 2-3 and 1-2 respectiveLy are mixed homogeneousLy to obtain a materiaL C, the materiaL C is Laid on an egg coLLecting board to coLLect fLy eggs, and the materiaL A and the fLy eggs are added, hatching, continuous breeding, and the fLy maggots and fLy maggots excrement are separated to obtain fLy maggot aduLts; and 4) Earthworm aquacuLture: earthworms are breed with the materiaL A that breeds maggots. The method has the characteristics of high materiaL utiLization rate and deLaying earthworm germpLasm degradation.

Description

technical field [0001] The present invention relates to the technical field of comprehensive recovery and utilization of resource regeneration. More specifically, the invention relates to a method for resource utilization of kitchen waste. Background technique [0002] Kitchen refers to the general term of leftovers, table waste and kitchen scraps. It is the main component of the organic phase in municipal solid waste. Kitchen waste is rich in vitamins, starch, protein, oil, edible fiber, fatty acids, sugar, and salt. It is an ideal raw material for fly maggot and earthworm breeding. However, food waste is rich in a large amount of oil. If food waste is directly used to feed fly maggots and earthworms, the culture medium is often hypoxic and acidified due to the rich oil in the breeding qualification, resulting in the death of fly maggots and earthworms. Growth or even death, resulting in breeding failure. Contents of the invention [0003] An object of the present inve...
