Problems solved by technology

This method has a lot of equipment and complex operation, and if the living area of ​​livestock and poultry is not cleaned for a long time, it is easy to cause diseases of livestock and poultry
The existing technology also uses elevated net beds to breed livestock and poultry. The lower part of ordinary elevated net beds is the place for feces collection, which is likely to cause stench in the breeding warehouse, and the hygienic conditions cannot be guaranteed, which increases the risk of livestock and poultry infection

Embodiment 1

[0058] About 12 tons of high-concentration organic wastewater and manure are discharged from a pig farm in a certain base every day, and about 8 tons of wastewater are sprayed by the spray unit to the fermentation pile. The hog breeding period is 6 months. After the hogs are slaughtered, the organic litter is transferred to the fermentation pile, and the elevated mesh bed 210 is washed. Pig farm sewage mainly includes pig urine and a small amount of flushing water. Its main characteristics are: high concentration of organic matter, high suspended solids, deep color, and a large number of bacteria. Due to the large amount of animal excrement, NH 3 - High N concentration (300mg / L). Pollutants in sewage mainly exist in the form of dissolved carbohydrates, which make the sewage show a high BOD 5 (3600mg / L), COD cr (8000mg / L) and chromaticity, etc. The pollutants have good biodegradability. In addition, the sewage contains a large amount of nutrients such as N and P. The TP conce...

Embodiment 2

[0064] The basic content of this embodiment is the same as that of Embodiment 1, and the difference is that: in this embodiment, no machine bedding material is laid on the elevated net bed 210, and the excrement of livestock and poultry falls from the elevated net bed 210 to the collection unit 300, and then Realize solid-liquid separation. The feces of the collection unit 300 are collected to the fermentation layer 400 by a manure hanging machine, and the solid waste of livestock and poultry is composted in the fermentation layer 400, and at the same time, the fermentation liquid of the fermentation device is sprayed on the feces. When cultivating for 30 days, foul smell appeared in the cultivating area 200 domain of the elevated net bed 210.

Embodiment 3

[0066] The basic content of this embodiment is the same as that of Embodiment 1, the difference being that: in this embodiment, the elevated net bed 210 is laid with machine padding, and the laying thickness is 20 cm. No water collection unit is provided between the elevated net bed 210 and the fermentation layer 400 , that is, the culture wastewater almost all leaks down to the fermentation layer 400 . Because domestic pigs have the habit of fixed-point excretion, the breeding wastewater is concentrated in a certain area of ​​the fermentation layer 400, resulting in excessive logistics humidity in this area, which affects fermentation; at the same time, the fermentation of materials in other areas of the fermentation layer 400 is not complete, affecting the overall fermentation efficiency .

Abstract

The invention belongs to the field of breeding waste treatment, and particularly relates to a livestock and poultry waste circulating system based on organic padding and an operation method of the livestock and poultry waste circulating system. A breeding bin of the fermentation system comprises an elevated net bed, a fermentation layer and a sewage blending layer, wherein organic padding is arranged on the elevated net bed, and the elevated net bed is used for providing a living space for livestock and poultry; the fermentation layer is used for fermenting solid wastes generated by the elevated net bed; a collecting unit of the sewage blending layer is located below the elevated net bed and used for collecting breeding wastewater and conveying the breeding wastewater to a fermentation device through a pipeline; a spraying unit is connected with the fermentation device through a spraying pipe, and the spraying unit is positioned right above the fermentation layer and can spray the fermentation layer. Breeding, solid-liquid separation, sewage treatment and solid waste treatment are integrated, so that the number of equipment and the occupied area of a plant are greatly reduced, the disease infection rate of livestock and poultry is reduced, and reduction, recycling and energy regeneration of livestock and poultry wastes are achieved.

Description

technical field [0001] The invention belongs to the field of breeding waste treatment, and more specifically relates to a livestock and poultry waste circulation system based on organic litter and an operating method thereof. Background technique [0002] With the continuous improvement of my country's economic level, the animal husbandry industry has developed rapidly, but at the same time as the animal husbandry industry has flourished, a large amount of livestock and poultry waste has also been produced, which has become the main source of agricultural non-point source pollution in my country, and the environmental pollution problems caused by it are also increasing. increasingly severe. Therefore, the resource utilization of livestock and poultry waste, the construction of a livestock and poultry waste treatment system and the construction of a sustainable development system of agricultural and animal husbandry cycles have become a top priority in our country. [0003] A...
