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, high water content of food waste, and low calorific value, which will easily lead to difficult incineration, extremely poor economy, difficult tail gas treatment, and easy to form secondary pollution; the reduction and volume reduction of composting The effect is obvious, and it has good adaptability to food waste with high water content, which is conducive to the harmlessness of waste, but its operation and management level is high, and the advanced equipment and technology have a great impact on the technical effect, and the utilization of resources and calorific value low rate, slow processing

Embodiment 1

[0021] 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 larvae of the palm fly on the surface of the culture material, and the insertion density is: 0.2g larvae of the palm fly / kg culture material Maggots were cultured at 30°C. On the 4th day, a larger container was placed outside the culture container, and dry rice bran powder was sprinkled into it, so as to facilitate the collection of the palm fly maggot. After 4 to 5 days, the brown-tailed fly maggots 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-orga...

Embodiment 2

[0025] 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 larvae of the palm fly on the surface of the culture material. Cultivate the larvae of the palm fly larvae. On the 4th day, a larger container was placed outside the culture container, and dry rice bran powder was sprinkled into it, so as to facilitate the collection of the palm fly maggot. After 4 to 5 days, the brown-tailed fly maggots 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-organic fertilizer. .

Embodiment 3

[0030] 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 larvae of the palm fly on the surface of the culture material. Cultivate the larvae of the palm fly larvae. On the 4th day, a larger container was placed outside the culture container, and dry rice bran powder was sprinkled into it, so as to facilitate the collection of the palm fly maggot. After 4 to 5 days, the brown-tailed fly maggots 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-organic fertilizer. .

Abstract

The invention belongs to the field of environmental protection and relates to a method for treating restaurant and kitchen garbage by utilizing maggots of boettcherisca peregrine, which comprises the following steps: adding auxiliary materials after coarse crushing of the restaurant and kitchen garbage, obtaining a compost for the maggots of the boettcherisca peregrine, further inoculating larvaeof the maggots of the boettcherisca peregrine on the surface of the compost for the maggots of the boettcherisca peregrine, obtaining a feeding compost for the maggots of the boettcherisca peregrine and treating and clearing the garbage. A polypide collecting container is connected at the outside of a stacking region of the compost for the maggots of the boettcherisca peregrine before aging of the larvae of the boettcherisca peregrine, and dry rice bran powder is arranged in the polypide collecting container for guiding the collection of the aged maggots of the boettcherisca peregrine. The residual treated compost for the maggots of the boettcherisca peregrine is prepared into a biological organic fertilizer after drying, the method has strong treatment capacity and faster treatment speedin comparison with an ordinary manure, and the treatment cycle is 4-5 days; the capacity of the food garbage is reduced by 10-30% after the treatment, and the peculiar smell of the food garbage is reduced; and the method can obtain the high-quality biological organic fertilizer and high-quality insect bioprotein while treating the garbage.

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 utilizing the maggots of the palm-tailed hemp fly maggot. 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 ...
