Problems solved by technology

[0003] Sanitary landfill has the largest treatment capacity, relatively low operating costs, relatively simple process, and low investment. It is the final digestion method for residues produced by other treatment methods. The requirements are high, and water and air pollution cannot be completely solved; the incineration method has a high degree of reduction, the calorific value of garbage can be utilized, the degree of ground harmlessness is high, the land occupation is small, and the capacity reduction is large, up to 70-80%. This method requires large investment, high operating costs, hig

Embodiment 1

[0020] The sorted kitchen waste was collected in a paper bag. After coarse crushing, an appropriate amount of auxiliary materials was added and stirred evenly to prepare compost. The material formula of the compost was shown in Table 1. Pour the culture material into the corresponding container, the height of the culture material is 4cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material. Hatch into black soldier fly larvae. Black soldier fly eggs hatched into larvae on the 2nd day and began to feed on compost. On the 4th day, set a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of black soldier fly larvae. After 20 to 30 days, the black soldier fly larvae have reached the mature state, and they climbed out of the compost and fell into a larger container. The compost turned dark brown, the material was loose, and the odor was reduced. It was dried to make bio-o...

Embodiment 2

[0024] The sorted kitchen waste was collected in paper bags, and after coarse crushing, an appropriate amount of auxiliary materials was added and stirred evenly to prepare compost. The material formula of compost was shown in Table 2. Pour the culture material into the corresponding container, the height of the culture material is 6cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material. The egg density is: 0.6g black soldier fly eggs / kg culture material. Hatch into black soldier fly larvae. Black soldier fly eggs hatched into larvae on the 2nd day and began to feed on compost. On the 4th day, set a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of black soldier fly larvae. After 20 to 30 days, the black soldier fly larvae have reached the mature state, and they climbed out of the compost and fell into a larger container. The compost turned dark brown, the mate...

Embodiment 3

[0029] The sorted kitchen waste was collected in paper bags, and after coarse crushing, an appropriate amount of auxiliary materials was added and stirred evenly to prepare a compost. The material formula of the compost is shown in Table 3. Pour the culture material into the corresponding container, the height of the culture material is 8cm, and insert an appropriate amount of black soldier fly eggs on the surface of the culture material. The egg density is: 1g black soldier fly eggs / kg culture material, and hatch at 35°C after the eggs are inoculated. Become a black soldier fly larva. Black soldier fly eggs hatched into larvae on the 2nd day and began to feed on compost. On the 4th day, set a larger container outside the culture container, and sprinkle dry rice bran powder in it to facilitate the collection of black soldier fly larvae. After 20 to 30 days, the black soldier fly larvae have reached the mature state, and they climbed out of the compost and fell into a larger c...

Abstract

The invention belongs to the field of environmental protection, relating to a method for processing food waste by using black soldier fly larvae and comprising the following steps: coarse crushing the food waste and then adding auxiliary materials to obtain culture materials for the black soldier fly larvae; and grafting black soldier fly spawn on the surface of the culture materials for the black soldier fly larvae so that the larvae hatched by the black soldier fly spawn acquires the culture materials for the black soldier fly larvae, thereby processing and cleaning the food waste. Before the black soldier fly larvae ages, a polypide collecting container is externally connected to the area for piling up the culture materials for the black soldier fly larvae and is filled with dry rice bran powder so as to guide to collect the aged black soldier fly larvae; and the rest of the processed culture materials for the black solider fly larvae is dried and then prepared into microbial organic fertilizer. The invention has strong processing capability, rapid processing speed compared with the common compost, the processing period is 4-5 days; after being processed, the volume of the food waste is reduced by 10-30%, the peculiar smell of the waste is lightened; and the invention can obtain excellent microbial organic fertilizer and insect bioprotein at the same time.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a method for removing garbage, in particular to a method for treating kitchen garbage by using black soldier fly larvae. Background technique [0002] Kitchen waste accounts for about 40-50% of the total amount of urban waste. If it is stored for a long time, it will breed germs, mosquitoes, and cockroaches, increase kitchen odor, and affect the health of residents and the home environment. Food waste is a difficult point in municipal solid waste disposal. At present, the main treatment methods of urban food waste are sanitary landfill and incineration, and a small part is treated by composting. [0003] Sanitary landfill has the largest treatment capacity, relatively low operating costs, relatively simple process, and low investment. It is the final digestion method for residues produced by other treatment methods. The requirements are high, and water and air pollution can...
