Embodiment 1

[0033] The method of utilizing dairy farm manure to produce environment-friendly litter of the present invention comprises the following steps:

[0034] The first step: solid-liquid separation: the cow dung is separated by a solid-liquid separator, and the moisture content of the dung residue after dehydration is about 70%;

[0035] Step 2: Stacking: When the outside temperature is lower than 0°C and the temperature in the pile cannot reach 50°C, add the compound microbial agent to the dung to be fermented at a ratio of 3‰, turn the pile until it is evenly mixed. Stack the dung with the water content adjusted to 50%, and stack it into a long pile with a width of about 1.8 meters and a height of about 1.5 meters. The length can be determined according to the length of the fermentation site;

[0036] Step 3: Fermentation: Ferment the stacked piles of feces. The fermentation process generally goes through stages of heating, high temperature, and cooling. When the temperature reac...

Embodiment 2

[0047] The method of utilizing dairy farm manure to produce environment-friendly litter of the present invention comprises the following steps:

[0048] The first step: solid-liquid separation: the cow dung is separated by a solid-liquid separator, and the moisture content of the dung residue after dehydration is about 70%;

[0049] Step 2: Stacking: Pile up the dung with a moisture content of 60%, and stack it into a long stack with a width of about 1.8 meters and a height of about 1.5 meters. The length can be determined according to the length of the fermentation site;

[0050] Step 3: Fermentation: Ferment the stacked piles of feces. The fermentation process generally goes through stages of heating, high temperature, and cooling. When the temperature reaches 55°C, it starts to turn the pile, and turns it every 2 days;

[0051] Step 4: Indicator control: The fermented cow mattress material is tested for the microbial indicators that cause mastitis in dairy cows, and it can ...

Embodiment 3

[0053] The method of utilizing dairy farm manure to produce environment-friendly litter of the present invention comprises the following steps:

[0054] The first step: solid-liquid separation: the cow dung is separated by a solid-liquid separator, and the moisture content of the dung residue after dehydration is about 70%;

[0055] The second step: stacking: add the compound microbial agent to the dung to be fermented at a ratio of 1‰, turn over the pile until it is evenly mixed. Stack the manure with the moisture content adjusted to 70%, and stack it into a long pile with a width of about 1.8 meters and a height of about 1.5 meters. The length can be determined according to the length of the fermentation site;

[0056] Step 3: Fermentation: Ferment the stacked piles of feces. The fermentation process generally goes through stages of heating, high temperature, and cooling. When the temperature reaches 55°C, it starts to turn the pile, and turns it every 2 days;

Abstract

The invention relates to the fields of animal husbandry environment pollution treatment and waste recycling, and concretely relates to a method for producing an environmentally friendly bedding material by using dairy cattle farm wastes. The method for producing the environmentally friendly bedding material by using cattle farm wastes comprises the following steps: 1, carrying out solid-liquid separation to make the water content of dehydrated night soil of 70% or below; 2, stacking, and maintaining the water content of the night soil in a range of 55-70% in the stacking process; and 3, fermenting the stacked night soil, turning stacked night soil when the temperature in the stacked night soil reaches 55DEG C, carrying out heat insulation for 7d or above when the temperature in the stacked night soil reaches 70DEG C or above, and adjusting the water content of the night soil to 20-35% when the temperature in the stacked night soil decreases to 50DEG C or below in order to obtain the bedding material. The dairy cattle night soil is stacked and fermented, and is recycled as the bedding material, so zero discharge of the dairy cattle night soil is reached, and the comprehensive utilization of the dairy cattle night soil is realized.

Description

technical field [0001] The invention relates to the fields of animal husbandry environmental pollution control and waste recycling, in particular, the invention relates to a method for producing environment-friendly litter by using dairy farm manure. Background technique [0002] In recent years, with the rapid development of intensive dairy farms, the problem of environmental pollution caused by concentrated discharge of cow manure has become increasingly prominent, seriously affecting the sustainable development of the dairy farming industry itself. In response to the environmental pollution problems of the dairy farming industry, the "National Environmental Protection "Twelfth Five-Year Plan" has also formulated clear goals. According to the principles of resource utilization, harmlessness and reduction in the prevention and control of animal husbandry pollution, large-scale animal husbandry across the country will be implemented. The prevention and control of breeding pol...
