Embodiment 1

[0029] A pig farm manure treatment method, comprising separating the excrement of pigs into dry manure and manure water, and the dry manure is fermented and used as raw materials for producing organic compound fertilizer and fish feed respectively, and the manure water is divided into two parts for processing, A part of the manure is discharged into the biogas digester for biogas production, and the other part of the manure is sent into the sedimentation tank for sedimentation and disinfection, and the manure is used for cleaning pig houses after sedimentation and disinfection.

[0030] Further, the amount of manure used to produce biogas is preferably set to 3 / 4 of the total amount of manure, and the amount of manure used for precipitation disinfection is preferably set to 1 / 4 of the total amount of manure, wherein the amount of manure used to produce biogas The amount of water and the amount of feces used for sedimentation and disinfection are reasonably allocated according t...

Embodiment 2

[0038] This embodiment is basically the same as the above-mentioned embodiment, the main difference is that the sedimentation tank is divided into a first natural sedimentation tank, a second high-temperature disinfection sedimentation tank and a third cooling sedimentation tank, and the third cooling sedimentation tank is arranged in the second disinfection sedimentation tank Below the pool, the second high-temperature disinfection sedimentation tank is set under the first natural sedimentation tank. The first natural sedimentation tank is used for natural precipitation of feces, and the natural precipitation time is 1 day; the second high-temperature disinfection sedimentation tank is used for natural After the precipitation, the feces are disinfected, and the hot water after high temperature disinfection is sent to the third cooling pool, and the cooled water is used to clean the pig house;

[0039] Yet another preferred implementation manner of this embodiment is that the d...

Embodiment 3

[0041] This embodiment is basically the same as the above-mentioned embodiment, the main difference is that the sedimentation tank is divided into a first natural sedimentation tank, a second high-temperature disinfection sedimentation tank and a third cooling sedimentation tank, and the third cooling sedimentation tank is arranged in the second disinfection sedimentation tank Below the pool, the second high-temperature disinfection sedimentation tank is set under the first natural sedimentation tank. The first natural sedimentation tank is used for natural precipitation of feces, and the natural precipitation time is 3 days; the second high-temperature disinfection sedimentation tank is used for natural After the precipitation, the feces are disinfected, and the hot water after high temperature disinfection is sent to the third cooling pool, and the cooled water is used to clean the pig house;

[0042] Yet another preferred implementation manner of this embodiment is that the ...

Abstract

The invention discloses a manure treatment method in a pig farm. The manure treatment method comprises the following step of: separating the excrement of pigs into dry manure and liquid manure, wherein the dry manure is taken as a raw material for producing organic compound fertilizer and a fish feed respectively after being fermented; and the liquid manure is treated in two parts, one part is discharged into a biogas digester for producing biogas, the other part is sent into a settling pond for settling and disinfecting, and the liquid manure is used for cleaning pigpens after being subjected to settling and disinfecting treatment. The pollution problem caused by waste water of pig manure and urine is effectively solved, the treated pig manure and urine waste water can be applied to various related industries, and greater benefits are brought for farmers.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method for treating pig farm feces. Background technique [0002] With the rapid development of my country's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. If a large amount of pig manure and urine wastewater is not treated properly, the water quality will be affected. Because pig manure and urine contain a large amount of Organic matter and organisms will consume dissolved oxygen in water during decomposition, thereby destroying the ecological balance. For example, when the source of tap water is polluted by pig feces and urine wastewater, the water will contain odor, which will affect people's drinking; second, it will hinder environmental sanitation, because Pig manure will emit a pungent odor, and it is easy to breed mosquitoes and flies, which seriously affects th...
