[0057] Example 1: A method for processing human excrement provided by the present invention, refer to figure 1 As shown, it includes the following steps: (1) After removing the human excrement, the liquid in the human excrement is discharged into the original liquid storage tank, and the solid is dehydrated;
[0058] (2) The solid obtained after the step (1) dehydration treatment is crushed, and then evenly filled into the fully enclosed fermentation tank through the distributor for aerobic fermentation; the liquid in the step (1) stock tank is separated from the solid and liquid , After filtration treatment, the supernatant obtained is sterilized and used as liquid fertilizer; the raw material liquid of liquid fertilizer can also be discharged after water treatment;
[0059] (3) After step (2) fermentation, the impurities in the fermented material are sprayed and washed to discharge, and then the material liquid is separated into solid and liquid, and the separated solid material i...
Example Embodiment
[0065] Embodiment 2: In addition to the technical solution disclosed in Embodiment 1, in order to further optimize the present invention, refer to the method flowchart figure 2 As shown, the liquid discharged from the solid after dehydration in the step (1) is discharged into the raw liquid storage tank.
[0066] Further, in the step (2), after the liquid in the raw liquid storage tank is separated from the solid and liquid, the separated solid materials are dehydrated and crushed, and then evenly filled into the fully enclosed fermentation by the distributor for aerobic fermentation , The liquid discharged in the dehydration process enters the original liquid storage tank.
[0067] Further, the filter residue obtained by filtering the liquid in the raw liquid storage tank in the step (2) is dehydrated and crushed, and then enters the fully enclosed fermentation tank through the distributor for aerobic fermentation.
[0068] Further, after the solid-liquid separation and dehydration...

[0093] Embodiment 3: A method for processing human excrement provided by the present invention includes the following steps: (1) After removing the human excrement, the liquid in the human excrement is discharged into a raw liquid storage tank, and the solid is dehydrated;
[0094] (2) The solid obtained after the step (1) dehydration treatment is crushed, and then evenly filled into the fully enclosed fermentation tank through the distributor for aerobic fermentation; the liquid in the step (1) stock tank is separated from the solid and liquid , After filtration, the supernatant obtained is sterilized and used as liquid fertilizer;
[0095] (3) After step (2) fermentation, the impurities in the fermented material are sprayed and washed to discharge, and then the material liquid is separated into solid and liquid, and the separated solid material is subjected to secondary fermentation after dehydration and crushing;
[0096] (4) After the secondary fermentation is finished, the granu...
