Problems solved by technology

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

[0027] Such as figure 1 Shown utilizes the method for processing kitchen waste of black soldier fly, and described method comprises the following steps:

[0028] The first step is pretreatment of food waste, filtering, sorting, crushing and stacking of food waste;

[0029] The specific operation steps are as follows:

[0030] 1) Weighing. After the kitchen waste is transported into the site by the transport vehicle, it is weighed and recorded by the electronic truck scale, and then transported to the designated position in the receiving room, and the garbage in the vehicle is discharged into the receiving hopper;

[0031] 2) Filtration and sorting, first use the conveyor to transport the food waste in the receiving hopper to the three-phase separator, and conduct preliminary separation of grease, water and solid substances in the food waste; then sort and remove large-diameter solid debris;

[0032] 3) Crushing and stacking, first convey the cleaned food waste to the pulver...

Abstract

The invention discloses a method for treating kitchen waste by using hermetia illucens. The method comprises the following steps: step 1, kitchen waste pretreatment: filtering, sorting, crushing and stacking the kitchen waste; step 2, larva inoculation: flatly laying the pretreated kitchen waste in a waste treatment box, and then inoculating larvae hatched by hermetia illucens eggs into the kitchen waste; and step 3, material and larva separation: collecting and separating mature larvae of the hermetia illucens after breeding treatment and material residues. According to the method for treating the kitchen waste by using the hermetia illucens, the consumption capacity of the kitchen waste is high, the treatment period of the kitchen waste is shortened, breeding of the hermetia illucens larvae is facilitated, and the hermetia illucens larvae can stably and rapidly grow.

Description

technical field [0001] The invention relates to a method for treating kitchen garbage by using black soldier flies, and belongs to the technical field of kitchen garbage treatment. Background technique [0002] Food 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. At present, the main treatment methods of urban kitchen waste are sanitary landfill and incineration, and a small part is treated by composting. 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 b...
