Embodiment 1

[0029] A method for treating manure in a pig farm, comprising separating pig excrement into dry manure and manure water. The dry manure is fermented and used as raw material for the production of organic compound fertilizer and fish feed. The manure water is processed in two parts, Part of the manure water is discharged into the biogas tank to produce biogas, the other part of the manure water is sent to the sedimentation tank for sedimentation and disinfection, and the manure water is used for cleaning the pig house after sedimentation and disinfection.

[0030] Further, the amount of manure water used for the production of biogas is preferably set to 3 / 4 of the total amount of manure water, and the amount of manure water used for sedimentation and disinfection is preferably set to 1 / 4 of the total amount of manure water. The amount of water and the amount of manure water used for sedimentation and disinfection are reasonably distributed according to the size of the pig farm, and...

Embodiment 2

[0038] This embodiment is basically the same as the above 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. The third cooling sedimentation tank is set in the second disinfection sedimentation tank. Below the tank, the second high-temperature disinfection sedimentation tank is set below the first natural sedimentation tank. The first natural sedimentation tank is used for natural sedimentation of manure water, and the natural sedimentation time is 1 day; the second high-temperature disinfection sedimentation tank is used for natural sedimentation. The sedimented manure water is disinfected, and the hot water after high temperature disinfection is sent to the third cooling tank, and the cooled water is used to clean the pig house;

[0039] Another preferred implementation of this embodiment is that the disinfection tempe...

Embodiment 3

[0041] This embodiment is basically the same as the above 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. The third cooling sedimentation tank is set in the second disinfection sedimentation tank. Below the tank, 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 manure water, and the natural sedimentation time is 3 days; the second high-temperature disinfection sedimentation tank is used for natural sedimentation. The sedimented manure water is disinfected, and the hot water after high temperature disinfection is sent to the third cooling tank, and the cooled water is used to clean the pig house;

[0042] Another preferred implementation of this embodiment is that the disinfection temp...

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 specifically relates to a method for treating manure of a pig farm. Background technique [0002] With the rapid development of the pig industry in China and the continuous expansion of the pig herd, the discharge of pig manure and urine is also increasing sharply. If a large amount of pig manure wastewater is improperly treated, it will affect the water quality. The organic matter and organisms consume dissolved oxygen in the water when decomposed, thereby destroying the ecological balance. For example, when the water source of tap water is polluted by pig manure wastewater, the water will have odor and affect people's drinking; second, it will hinder environmental sanitation. Pig feces and urine will give off a pungent odor, and it is easy to breed mosquitoes and flies, which seriously affects the quality of the living environment of neighboring communities and is harmful to health;...
