Wherein, in the state that the fan 51 pumps out the gas from the decomposition box 1, the gas is treated by photocatalysis by the sterilizing mechanism 52, the odor is absorbed by the deodorizing mechanism 53, the gas is filtered by the filtering mechanism 54, and finally the gas is purified by the negative ion piece 55 and then is discharged; and water generated by garbage decomposition is stored in the water storage tank, so that water recycling is realized, and water resources are saved.

Finally, the present embodiment further includes an outer casing 8 with a hollow interior, the decomposition box 1 is disposed in the outer casing 8, a panel 9 for human-computer interaction is further disposed on the upper portion of the outer casing 8, an opening 81 is disposed at a position corresponding to the inlet 12 on the outer casing 8 and the decomposition box 1, a cover 82 is hinged to the opening 81, and a sealing ring 83 is disposed between the cover 82 and the decomposition box 1; a driving motor 21 for driving the stirring mechanism 2 to rotate is also arranged in the outer shell 8.

In summary, the kitchen waste treatment method comprises the following use processes: in this embodiment, the decomposition process of the kitchen waste is illustrated by the devices shown in fig. 3 to 5:

step A: the kitchen garbage is poured into the decomposition barrel 1 from the inlet 12 of the decomposition barrel 1;

and B: a stirring mechanism 2 in the decomposition barrel 1 is used for stirring the kitchen garbage;

step C-E: the temperature sensor 31 and the humidity sensor 41 monitor the temperature and the humidity in the decomposition barrel 1 in real time, so that the temperature and the humidity in the decomposition barrel 1 are always kept in a preset range; when the temperature sensor 31 monitors that the temperature in the decomposition barrel 1 is lower than a preset value, the control panel 6 controls the heater 32 to heat the decomposition barrel 1; when the humidity sensor 41 detects that the humidity in the decomposition bucket 1 is lower than the preset value, the control board 6 controls the water pump 43 to pump water from the water storage tank 42 and spray water into the decomposition bucket 1 through the water spray opening 44; when the temperature sensor 31 or the humidity sensor 41 monitors that the temperature or the humidity in the decomposition barrel 1 is higher than a preset value, the control panel 6 controls the fan 51 to work, gas is pumped out from the decomposition barrel 1, water vapor in the pumped gas is sterilized by the sterilization system 52 and condensed and then stored in the water storage tank 42, and the rest gas except the water vapor is sterilized by the sterilization system 52, deodorized by the deodorization system 53, filtered by the filtering system 54, and finally purified by the negative ion piece 55 and discharged outwards;

step F: the heater 32 continuously heats the decomposition barrel 1, and kills harmful bacteria, pathogen bacteria and ova at high temperature;

step G: the kitchen garbage is decomposed and converted into organic fertilizer.
