Problems solved by technology

[0006] The method disclosed in CN101889629A can effectively deal with sorted kitchen waste. However, the implementation of garbage classification in China is poor at present. Most areas have not effectively classified garbage. The food waste has complex components and various forms of impurities. The pre-treated kitchen waste has high water content, high oil content and high salt content, as well as excessive waste tableware, plastics, paper towels, fruit peels, fruit cores and other sundries, which restrict the use of black soldier fly larvae to treat food waste industry. The main factors of application

Embodiment 1

[0043] After further dehydration, the desalinated food waste and auxiliary materials are prepared at a dry mass ratio of 1:0.1 to make bright-spotted flat-horned soldier fly feed with a moisture content of 50wt%. 40 parts, 30 parts of pig manure, and 1 part of quicklime are mixed evenly and stacked for no less than 3 days, then add 3 parts of biogas sludge, 4 parts of EM stock solution with a pH value of 5, and the number of viable bacteria not less than 500 million / ml. Finally, it is covered with a plastic film and fermented for 10 days. Lay flat-horned soldier fly feeding material, and inoculate 4-day soldier fly larvae with an inoculation density of 6000 / kg dry feed. After inoculation, feed in batches. Feed once a day and turn over once a day. The amount of feed is based on the feeding situation of the larvae. After 10 days of feeding, about 40% of the larvae will stop feeding when they turn black. Soldier flies leave the feed by themselves, enter the worm body collection ...

Embodiment 2

[0045]After further dehydration, the desalinated food waste and auxiliary materials are made into bright-spotted flat-horned soldier fly feed with a moisture content of 60wt% at a dry mass ratio of 1:0.5; the auxiliary materials are 35 parts of edible fungus residues by quality, straw powder 30 parts, 20 parts of poultry manure, and 2 parts of quicklime are mixed evenly and stacked for no less than 3 days, then add 2 parts of biogas sludge, 3 parts of EM stock solution with a pH value of 4, and the number of viable bacteria is not less than 500 million / ml. Finally, it is covered with a plastic film and fermented for 20 days. Flat-lay the soldier fly feeding material, and inoculate the soldier fly larvae for 5 days according to the inoculation density of 7000 / kg dry feed. After inoculation, feed in batches. Feed once a day and turn over once a day. The amount of feed depends on the feeding situation of the larvae. After 8 days of feeding, about 40% of the larvae turn black and ...

Embodiment 3

[0047] After further dehydration of the desalted kitchen waste, the dry mass ratio of 1:1 with auxiliary materials is used to make bright-spotted flat-horned soldier fly feed with a water content of 75wt%. 20 parts, 10 parts of pig manure and poultry manure, 3 parts of quicklime, mixed evenly and stacked for no less than 3 days, add 1 part of biogas sludge, EM stock solution with a pH value of 3 and a viable count of not less than 500 million / ml After the two parts are mixed, they are covered with plastic film and fermented for 30 days. Flat-lay the soldier fly feeding material, and inoculate the soldier fly larvae for 6 days according to the inoculation density of 8000 / kg dry feed. After inoculation, feed in batches, once a day and turn over once a day. The amount of feed is based on the feeding situation of the larvae. After 7 days of feeding, about 40% of the larvae turn black and stop feeding. Soldier flies leave the feed by themselves, enter the worm body collection cont...

Abstract

A kitchen garbage treatment method comprises the following steps of: sorting collected kitchen garbage, and after separating coarse solid substances, obtaining sorted kitchen garbage; further classifying the separated coarse solid substances, after breaking starch, celluloses, protein and lipid substances, merging the broken substances into the sorted kitchen garbage so as to obtain broken kitchen garbage, and carrying out burning treatment on remaining materials in the coarse solid substances; separating grease out of the broken kitchen garbage so as to obtain degreased kitchen garbage; treating the degreased kitchen garbage by a membrane filtration device so as to obtain desalted kitchen garbage; further dehydrating the desalted kitchen garbage, adding auxiliary materials, and making a hermertia illucens(L.) feed of which the water content is 50-75wt%; and inoculating hermertia illucens(L.) larvae, and supplying the hermertia illucens(L.) feed to the hermertia illucens(L.) larvae to eat, thereby treating and clearing away the kitchen garbage. The hermertia illucens(L.) larvae are used as feed or grease is extracted from the hermertia illucens(L.) larvae for making biodiesel, and remaining residues are used for making organic fertilizers.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a garbage removal treatment method, in particular to a kitchen garbage treatment method. Background technique [0002] Kitchen waste, commonly known as swill, also known as swill and swill, is the domestic waste formed by residents in the process of daily consumption. It is easy to rot and deteriorate, emits foul smell, and spreads bacteria and viruses. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, waste tableware, plastics, paper towels, fruit peels, fruit stones and other mixed solids. From the chemical composition, there are starch, cellulose, protein, lipid and inorganic salt. The main characteristics of food waste are rich in organic matter, high in water content, and perishable. If it is stored for a long time, it will breed bacteria, mosquitoes, and cockroaches, and increase ki...
