Embodiment 1

[0023] A method for black soldier fly biodegradation of kitchen waste, comprising the following steps:

[0024] (1) Filter the food waste, sort and remove inorganic debris, and pulverize the sorted food waste. The diameter of the pulverized food waste particles is less than 5mm;

[0025] (2) Evenly mix the pulverized kitchen waste with auxiliary materials to obtain a mixed feed; wherein, the food waste has 80 parts by weight, and the auxiliary materials have 20 parts by weight, and the auxiliary materials are wheat bran powder, straw powder, and oil cake , distiller's grains, and EM bacterial liquid; adjust the humidity of the mixed feed at 60% to 75%;

[0026] (3) Spread the mixed feed in the breeding box, the thickness of the mixed feed is 2cm, insert 3-day-old black soldier fly larvae, use the black soldier fly larvae to feed on the mixed feed, and maintain the breeding temperature at 25-35°C , regularly add mixed feed to the breeding box;

[0027] (4) When the black sold...

Abstract

The invention provides a method using Hermetia illucens L. to biologically degrade kitchen waste. The method includes: the kitchen waste is crushed and mixed with auxiliary materials to obtain mixed feed, the mixed feed is flatly laid into a cultivation box, Hermetia illucens L. larvae are inoculated into the mixed feed, the Hermetia illucens L. larvae eat the mixed feed to treat the kitchen waste, the Hermetia illucens L. larvae and Hermetia illucens L. larva excrement are screened when the Hermetia illucens L. larvae eat up the mixed feed in the cultivation box and are 7-8 days old, the dried Hermetia illucens L. larvae can be used as biological feed, and the excrement can be used as fertilizer after fermentation. The method is efficient, environmentally friendly and high in economic benefits.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for biodegrading kitchen waste by black soldier flies. Background technique [0002] With the improvement of people's living standards, the amount of domestic waste has increased. my country produces nearly 500 million tons of domestic waste every year, of which kitchen waste accounts for about 60% of the total domestic waste. How to dispose of kitchen waste reasonably, efficiently and safely is a problems that people have to face. At present, domestic food waste is generally simply filled up or incinerated, and a small part is treated as compost, and even used as cheap feed for pigs and other livestock. These methods more or less have problems such as large floor area, high treatment cost, low treatment efficiency, and easy to produce secondary pollution. [0003] The black soldier fly is a resource insect widely distributed throughout the ...
