Problems solved by technology

At present, the main treatment methods of urban food waste are sanitary landfill and incineration. The treatment capacity of sanitary landfill is large, the treatment address is limited, and the area is relatively large; when incineration is used, due to the high water content of food waste, the calorific value If it is too low, it will easily lead to difficult incineration, extremely poor economy, difficult tail gas treatment, and easy to form secondary pollution

Embodiment 1

[0025] (1) Separate the grease, water and solid matter in the food waste, and then sort the obtained solid matter (that is, the food waste solid residue), and remove large solid matter (large bone, etc.), Plastics (plastic disposable gloves, plastic cling film, plastic straws, etc.), wooden impurities (napkins, toothpicks, etc.), and then the food waste solid residue is crushed,

[0026] (2) drying the cyanobacteria salvaged from natural water bodies at 50°C, and crushing them to 40 meshes,

[0027] (3) 1 ton of solid slag of kitchen waste obtained in step (1) is mixed with cyanobacteria powder gained in 8 kilograms of steps (2) to fully obtain a mixture of kitchen waste, and the resulting mixture is kept at a constant temperature of 25° C. Evenly tiled indoors with a humidity of 65% RH, the laying height is 25cm, and the laying area is 4m 2 ,

[0028] (4) 90g (about 10,000 eggs in 1g) black soldier fly larvae were hatched for 5 days to obtain black soldier fly larvae whose ...

Embodiment 2

[0039] (1) Collect the leaves that fall from the sycamore tree in November and crush these leaves;

[0040] (2) drying the cyanobacteria salvaged from natural water bodies at 50°C, and crushing them to 40 meshes,

[0041] (3) 1 ton of pulverized leaves obtained in step (1) is fully mixed with 13 kilograms of blue-green algae powder obtained in step (2), and the resulting mixture is evenly mixed in a room with constant temperature of 25° C. and constant humidity of 65% RH. The ground is naturally tiled, and the tiled area is 120m 2 ,

[0042] (4) 90g (about 10,000 eggs in 1g) black soldier fly larvae were hatched for 5 days to obtain black soldier fly larvae whose individual volume was the size of a grain of rice, and all these black soldier fly larvae were spread evenly to the step (3 ) on the upper surface of the mixture obtained,

[0043] Persistent observation found that these black soldier fly larvae will eat the mixture of leaf fragments, so that the leaf fragments wil...

Abstract

The invention belongs to the technical field of organic waste treatment, and particularly relates to an organic waste biological treatment ecological cycle comprehensive resource utilization method and application. The method includes the steps: firstly, sufficiently mixing organic waste and blue-green algae; secondly, hatching black water fly eggs into larvae to be inoculated into mixture, separating materials and larvae after the mixture is treated for a period of time, taking the separated young black water fly larvae as feed of shellfishes, and taking treated materials after materials andlarvae separation as organic fertilizers.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment, and in particular relates to a comprehensive utilization method and application of organic waste biological treatment ecological cycle resource utilization. Background technique [0002] Kitchen waste accounts for about 40-50% of the total amount of urban waste, and it is easy to breed germs, mosquitoes, and cockroaches, increase odor, and affect the environment and the health of residents. At present, the main treatment methods of urban food waste are sanitary landfill and incineration. The treatment capacity of sanitary landfill is large, the treatment address is limited, and the area is relatively large; when incineration is used, due to the high water content of food waste, the calorific value If it is too low, it will easily lead to difficulty in incineration, extremely poor economy, difficult tail gas treatment, and easy to form secondary pollution. [0003] The scientific ...
