Method for eliminating food rubbish

Abstract

The invention discloses a method for eliminating food rubbish. The method comprises the following steps of: breaking the food rubbish after being classified, adding auxiliary materials so as to acquire a food rubbish breeding material, putting the food rubbish breeding material in housefly eggs and making the larva hatched from the housefly egg eat the breeding material till the food rubbish is eliminated. The food rubbish breeding material comprises 50 to 90 wt.% of food rubbish, 0 to 40 wt.% of saw dust, 0 to 30 wt.% of rice bran powder, 0 to 30 wt.% of bran, 0 to 40 wt.% of straw powder, 1 to 5 wt.% of yeast powder, 1 to 3 wt.% of EM liquid, 0 to 3 wt.% of baking soda and 0 to 3 wt.% of slaked lime. The food rubbish is eliminated by adding housefly eggs in the food rubbish breeding material and making the larva hatched from the housefly egg eat the breeding material. By performing harmless treatment on the food rubbish by using the housefly maggot, the method of the invention greatly decreases the capacity of the municipal solid waste, the generated housefly maggot biologic protein and the microbial organic fertilizer can realize the recycling of resource and the environment is protected.

Description

technical field [0001] The invention relates to the field of garbage removal, in particular to a method for removing food garbage. Background technique [0002] Urban 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. 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 cannot be completely solved; the incineration method has a high degree of reduction, the ca...

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
