Problems solved by technology

And when the existing methods are used, the organic fertilizer fermentation process using livestock and poultry manure as raw material is open fermentation. The smell and state of human manure are better than that of livestock and poultry manure. The original process and equipment cannot meet the requirements of human manure.

Embodiment 1

[0057] Embodiment one: a kind of method for processing human excrement provided by the present invention, refer to figure 1 As shown, the following steps are included, (1) after the human excrement is removed, the liquid in the human excrement is discharged into the raw liquid storage tank, and the solid is dehydrated;

[0058] (2) The solid obtained after the dehydration treatment in step (1) is crushed, and then evenly filled into a fully enclosed fermentation tank through a distributor for aerobic fermentation; the liquid in the raw liquid storage tank in step (1) is separated from solid to liquid 1. After filtration, the obtained supernatant is sterilized and used as a liquid fertilizer; the raw material liquid of the liquid fertilizer can also be discharged after water treatment;

[0059] (3) After step (2) is fermented, spray, wash and discharge the sundries in the fermented material, then carry out solid-liquid separation of the feed liquid, and carry out secondary ferm...

Embodiment 2

[0065] Embodiment 2: In addition to the technical solution disclosed in Embodiment 1, in order to further optimize the present invention, the method flow chart refers to figure 2 As shown, in the step (1), the liquid discharged after the solid is dehydrated is discharged into the raw liquid storage tank.

[0066] Further, after the liquid in the raw liquid storage tank in the step (2) is separated from the solid and liquid, the separated solid material is dehydrated and crushed, and then evenly filled into the fully enclosed fermentation via the distributor for aerobic fermentation , The liquid discharged from the dehydration process enters the raw liquid storage tank again.

[0067] Further, in the step (2), the filter residue obtained after filtering the liquid in the raw liquid storage tank is dehydrated and crushed, and then enters a fully enclosed fermentation tank through a distributor for aerobic fermentation.

[0068] Further, after the solid-liquid separation and de...

Embodiment 3

[0093] Embodiment 3: A method for processing human excrement provided by the present invention includes the following steps, (1) after removing impurities from human excrement, the liquid in human excrement is discharged into a raw liquid storage tank, and the solid is dehydrated;

[0094] (2) The solid obtained after the dehydration treatment in step (1) is crushed, and then evenly filled into a fully enclosed fermentation tank through a distributor for aerobic fermentation; the liquid in the raw liquid storage tank in step (1) is separated from solid to liquid 1. After the filtration treatment, the obtained supernatant is sterilized and used as a liquid fertilizer;

[0095] (3) After step (2) is fermented, spray, wash and discharge the sundries in the fermented material, then carry out solid-liquid separation of the feed liquid, and carry out secondary fermentation after the separated solid material is dehydrated and crushed;

[0096] (4) After the secondary fermentation is fi...

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...
