Example Embodiment

[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...

Abstract

The invention discloses a method for treating human excrement. The method comprises the steps as follows: (1) a liquid in the human excrement is discharged into an original liquid storage tank, and solids are dehydrated; (2) solids obtained after dehydration treatment in the step (1) are subjected to aerobic fermentation after being crushed; (3) secondary fermentation is performed; (4) materials obtained after the secondary fermentation are used as solid fertilizer. The invention also discloses a system adopting the method. The system comprises impurity removal equipment A, a dewatering deviceA, the original liquid storage tank, a crusher A, a distributor A, a full-closed fermentation tank A, an oxygen generator and the like. The method and the system for treating the human excrement havethe advantages as follows: a complete production process is provided for recycling of human excrement, a scheme is provided for urban emission reduction and sewage treatment plant pressure reduction,waste can be reused, and sustainable development can be realized really.

Description

technical field [0001] The invention belongs to the technical field of ecological environment, and specifically relates to a method and system for treating human excrement. Background technique [0002] Human excrement, excrement and urine are equivalent to farm manure like livestock and poultry manure. Compared with chemical fertilizers, human excrement has the advantages of wide sources, complete nutrients, long-lasting fertilizer effect, ability to improve soil and low cost, and can be used as top dressing and base fertilizer. In the prior art, when human excrement and urine are processed, since human excrement and urine contain a large number of germs, insect eggs and other harmful substances, they will pollute soil, air, water sources and crops, and then spread diseases, causing serious harm to human health. , so they all need to be used after high-temperature composting. [0003] Human excrement has been used for thousands of years in our country's farming civilizati...
