Method for processing utensil rubbish by Chrysomya megacephala maggot and material formula

Abstract

The invention belongs to the field of environmental protection, relating to a method for processing utensil rubbishes by Chrysomya megacephala maggot. The method comprises the following steps: after the utensil rubbishes are coarsely crushed, auxiliary materials are added to obtain a Chrysomya megacephala maggot culture material; Chrysomya megacephala ovum is accessed on the surface of the Chrysomya megacephala maggot culture material; the larvae incubated by the Chrysomya megacephala maggot eat and decompose the culture material to process and clear the utensil rubbishes. Before the Chrysomya megacephala larvae are aged, the outer part of Chrysomya megacephala maggot culture material stacking area is connected with a polypide collection container in which dried rice bran powder is arranged for guiding and collecting aged Chrysomya megacephala maggot. Residual processed Chrysomya megacephala maggot culture material is dried and processed into an organic fertilizer. The method of the invention has strong processing capability and higher processing speed than common compost; the processing period is 4-5 days; after processed, the capacity of the utensil rubbishes is reduced by 10-30%, and a peculiar smell is reduced; high-quality organic fertilizer and high-quality insect biologic protein are obtained while processing the utensil rubbishes.

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 the golden 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 water and air pollution canno...

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
