Embodiment 1

[0058] Such as figure 1 As shown, the embodiment of the present invention provides a method for combined treatment of dead pigs and pig manure, which is suitable for harmless and resourceful treatment of animal carcasses and manure in large-scale farming, especially for large-scale pig farms Sick and dead pigs are mixed with pig manure for ultra-high temperature composting.

[0059] The steps of the joint processing method include:

[0060] In step S1, the sick and dead pigs are crushed into uniform particles by a crusher.

[0061] Step S2, mixing the sick and dead pig particles crushed in step S1 with the drained pig manure to obtain a mixture of sick and dead pigs and pig manure.

[0062] Step S3, according to the water content and C / N ratio of the mixed material obtained in step S2, add an appropriate amount of auxiliary materials to the mixed material to adjust the water content and C / N ratio of the mixed material.

[0063] Step S4, inoculating the ultra-high-temperatur...

Embodiment approach

[0071] In one embodiment, all the mixed materials are put into the reaction tank 1 for composting reaction, and are completely taken out after the fermentation is completed. The height of the pile is controlled within the range of 2.0m~2.5m. The internal temperature of the pile exceeds 80°C within 1.0~2.0d after the start of the reaction, and the duration of the internal temperature of the pile at 80°C~90°C exceeds 7d, or even reaches 10~12d, the cycle of the whole composting reaction is 20~24d. The organic fertilizer obtained after 20 days of composting reaction meets the requirements of the national standard "Organic Fertilizer NY525-2021".

[0072] One embodiment, the mixed material is put into the reaction tank 1 from the upper part, after the composting fermentation reaction, it is discharged from the bottom of the reaction tank 1 in turn, and when the reacted organic fertilizer product is discharged, it is supplemented from the top of the reaction tank 1 at the same time...

Embodiment 2

[0077] Such as figure 2 As shown, this embodiment provides a reaction tank 1, which is suitable for the composting and fermentation reaction of dead pigs and pig manure.

[0078] Such as figure 2 As shown, the reaction tank 1 includes a tank body 11, an aeration device and the like. Wherein, the upper part of the tank body 11 is open, and the mixed material is put into the tank body 11 through the upper opening, and the tank body 11 is used for accommodating the mixed material for composting fermentation reaction. One side of the tank body 1 is provided with a sealed and fitted door panel (not shown in the figure), which can be opened to facilitate the discharge of materials after the fermentation is completed. The upper opening of the tank body 11 can be provided with a cover and an exhaust pipe, so as to facilitate the collection of waste gas produced by fermentation for deodorization.

[0079] The aeration device includes an aeration fan 2 and several aeration pipes 21...

Abstract

The invention provides a combined treatment method for pigs died of illness and pig manure, and aims to overcome the defects and defects in the existing treatment process of the pigs died of illness, the method comprises the following steps: step S1, crushing the pigs died of illness into uniform particles; s2, mixing the crushed particles of the dead pigs with pig manure to obtain a mixed material; s3, auxiliary materials are added into the mixed material, and the water content and the C / N ratio of the mixed material are adjusted; step S4, inoculating an ultra-high-temperature microbial inoculum into the mixed material treated in the step S3, and uniformly mixing the mixed material and the ultra-high-temperature microbial inoculum; and S5, putting the inoculated mixed material in the step S4 into a reaction tank, and carrying out a composting reaction to obtain an organic fertilizer crude product after the reaction. The method is short in treatment period, low in equipment investment, low in treatment cost, high in pile body temperature, high in decomposition degree, free of secondary fermentation treatment and good in reduction and harmless treatment effect.

Description

technical field [0001] The invention belongs to the technical field of agriculture, animal husbandry and breeding, and in particular relates to a combined treatment method of dead pigs and pig manure. Background technique [0002] Pork is the most important meat food in my country, and pig breeding occupies a large proportion in my country's animal husbandry production, accounting for about 51% of the total output value of animal husbandry. Correspondingly, pig manure occupies the largest share in my country's livestock and poultry pollution. The annual production of pig manure is about 1.8 billion tons, accounting for 47% of the total livestock and poultry manure. If these pig manures are not properly treated, it will cause environmental problems and pose a threat to human health. [0003] In the production process of pig farms, pigs will inevitably die due to diseases, epidemics, etc., and the mortality rate is 5% to 10%. Since the introduction of African swine fever int...
