Embodiment 1

[0027] Embodiment 1: a kind of treatment device of pig house breeding excrement, such as figure 1 shown. The head end of the device is a solid-liquid separator 1. After the excrement washed out of the pig house is collected, it is separated into solid and liquid by the solid-liquid separator. The liquid outlet of the solid-liquid separator 1 is connected to the liquid storage cylinder 3; the solid outlet of the solid-liquid separator is connected to the carbonization furnace 2, and one side of the carbonization furnace is provided with a combustion furnace 5 that provides heat, and the discharge port of the carbonization furnace is connected to the liquid storage Barrel 3. There are three carbonization furnaces 2, and the three carbonization furnaces are respectively provided with combustion furnaces 5, and the two carbonization furnaces are connected by waste heat pipes 4. There are three liquid storage cylinders corresponding to the carbonization furnace.

Embodiment 2

[0043]Embodiment 2: A kind of treatment device of pig house breeding excrement. The liquid outlet of the solid-liquid separator 1 in this embodiment is connected to the biogas digester, and the biogas slurry outlet of the biogas digester is connected to the liquid storage cylinder. All the other structures are the same as in Example 1.

[0044] The process of this embodiment is as image 3 Shown: On the basis of the treatment process in Example 1, in step 2, the liquid matter is first transported to the biogas digester, and the liquid matter after fermentation treatment in the biogas digester is then transported to the liquid storage cylinder. The biogas mud in the biogas digester is used as the binder for granulation in step 5, and the fertility components in the biogas mud are fully utilized. All the other steps are the same as in Example 1.

Abstract

The invention relates to a livestock manure harmless treatment technology, and solves the problems of large quantity and great disposal difficulty of livestock manure. The technology comprises the steps of: 1. flushing a breeding site, and collecting livestock manure; 2. performing solid-liquid separation on the excrement, conveying the liquid to liquid storage cylinders, and transporting solid to a carbonization furnace; 3. conducting solid high temperature carbonization to form a carbonized solid; 4. putting the carbonized solid into liquid storage cylinders, and conducting static adsorption of ammonia nitrogen in the liquid; 5. after adsorption of ammonia nitrogen by the carbonized solid, carrying out crushing granulation to form a granular fertilizer; and 6. drying and sieving the granular fertilizer to form a carbon-based fertilizer finished product. The technology provided by the invention carries out solid-liquid separation on the livestock manure, performs carbonization on the solid, and conducts adsorption on the liquid with the carbonized solid to prepare the carbon-based fertilizer for returning to filed, reduces direct discharge of livestock manure, also reduces water consumption, and saves water resources.

Description

technical field [0001] The invention relates to a waste treatment device, in particular to a process for harmless treatment of poultry manure. Background technique [0002] my country is a big country in poultry and livestock breeding, and the scale of breeding ranks among the top in the world. Especially affected by people's eating habits, the scale of pig breeding in my country is huge, and the amount of poultry and livestock manure produced is large, which has a great impact on the environment. Take pig house breeding as an example: pigs have certain requirements on the breeding environment, especially under the condition of large-scale centralized breeding, the pig house environment needs to be taken care of regularly to avoid illness or even death of farmed pigs. During the breeding process, a large amount of pig manure will be produced in the pig house, which will cause the environment of the pig house to deteriorate. Therefore, it is necessary to wash and clean the ex...
