Pig manure management

What management technology can be used in the pig dung disposal system?

Our pig manure organic fertilizer making line provides organic fertilizer fermentation techniques. The conversion of pig dung to organic fertilizer is of great significance. Livestock and poultry manure is a traditional Chinese high-quality organic fertilizer. Increasing the application of organic fertilizers can reduce the amount of chemical fertilizers used, improve the soil structure, and significantly improve the quality of agricultural products. It is an important measure to promote the sustainable development of agriculture and the production of pollution-free agricultural products. It can not only effectively solve the environmental pollution problem of intensive livestock and poultry farms, prevent and control agricultural non-point source pollution, and realize clean production of animal husbandry, but also produce high-quality organic fertilizer products, promote the process of organic fertilizer industrialization, and realize the sustainable development of ecological agriculture to reach the region. The organic combination and coordinated development of “aquaculture” and “cropping industry” promotes a virtuous cycle of agricultural waste treatment and utilization.

Natural composting fermentation pig manure is piled in a fermentation tank, covered with straw, and after a long period of natural anaerobic fermentation (some up to several years), it is directly applied to the ground during the fertilization season. This method has been widely used in small farms in remote areas. The main reasons are: first, the small farm is located in a remote area, far away from residential areas, and the area is vast. Second, the natural composted and fermented fertilizer is used nearby in the small farm, not far away. However, most intensive livestock and poultry farms in China are concentrated in the suburbs of cities, very close to residential areas, and there is no large amount of land around to absorb the continuous production of pig manure.

The drying method is to spread pig manure evenly on the field and use solar energy for natural drying. The method has low investment and low cost, but it covers a large area, has serious environmental pollution, and has a lot of fertilizer nutrient loss. It is also difficult to produce normally in rainy and snowy seasons, and it is difficult for the product to meet the requirements of harmlessness. The method is suitable for the treatment of scattered livestock and poultry manure by livestock and poultry farms, but is not suitable for intensive livestock and poultry farms to process large and concentrated livestock and poultry manure.

The direct rapid drying method is a rapid processing method that uses high-temperature hot flue gas to directly dry and sterilize pig manure, and control the moisture content of the product below the safe storage moisture. The direct rapid drying method has the advantages of rapid processing, simple operation, good product quality, free from climate restrictions and continuous production. It was widely used in the fecal treatment of intensive chicken farms in the 1990s. However, this method has high energy consumption, and improper treatment of the drying tail gas is likely to cause secondary pollution. Therefore, when the moisture content of livestock manure is high or in areas where coal resources are scarce and environmental protection requirements are high, its usability is restricted.

Biogas anaerobic fermentation method uses pig manure from livestock farms as raw materials. In the biogas fermentation device, under the condition of isolating oxygen, through the action of microorganisms, the carbon element is finally decomposed into combustible gas (biogas). The biogas anaerobic fermentation method is suitable for the treatment of liquid livestock and poultry manure from the intensive livestock and poultry farms using the water flushing (or blister) manure removal process.

Production Process of Small Pig Manure Production Line

1. The production process: fermentation pool on the yeast – evenly into the bacterium agent – turn heap fermentation, fermentation 12-15 days — – points screen – crushing – premixed – (granules) packaging for sale
2. Fermentation process of small pig manure organic fertilizer production line
The production line process of pig manure organic fertilizer is mainly to mix the organic national waste with auxiliary materials (plant straw, etc.) and microbial fermentation agent with water content less than 50%, and make it fully mature, sterilize, deodorize and remove water through continuous aerobic fermentation. The moisture content of the decomposed pig manure is generally in the range of 30-35%. After screening , it can be directly used for granulation to produce spherical organic fertilizer, or further drying to produce powdered organic fertilizer.
3. Granulation process of small pig manure organic fertilizer production line
The pig manure organic fertilizer granulation process manufacturing line is mainly to screen the organic waste about 30-35% of fermented and mature water containing stars, granulate and dry to prepare round granular organic fertilizer, add functional bacteria to produce bio-organic fertilizer, and add nitrogen, phosphorus and potassium (the total nutrient imitation content is less than 15%) to produce organic fertilizer.

How to effectively compost the pig dung from pig farms?

The pig manure turning machine is characterized by saving a lot of manpower and material resources engineering, making the scale of fertilizer production more flexible, especially suitable for converting agricultural waste, stored manure and organic household garbage into high-quality bio-organic fertilizer.

Advantages of processing machine for pig manure fermentation: The machine is equipped with a high-pressure forced oxygen supply system, which can use the oxygen at the bottom of the tank to evenly supply oxygen to the material, which is convenient for fermentation. The side of the fermentation tank is equipped with a black fixed copper sliding contact electric winding to ensure safety, reliability and durability. The advantages of the pig manure turning machine are thorough turning, long moving distance, short fermentation cycle and strong production capacity.

It is reported that the fermentation cycle is about 1 week, the distance between the pile and the pile can reach about 10 meters, and the annual production capacity can reach 10,000 to 10,000 tons. This machine is widely used in the processing of various livestock and poultry manure, straw, mushroom planting and culture materials, and domestic garbage. The pig waste turning machine has become a forklift’s response tool for turning materials, replacing labor, and is a mainstream product that affects the development trend of the composting industry. It is rapidly multiplying in the family of fertilizer machinery and equipment.

Introduction to the characteristics of the pig manure piler equipment: It adopts a four-wheel walking design, and the rotating knife shaft mounted under the frame implements the mixing, fluffing and shifting of the raw materials of the pile, which can be reversed, forwarded, and turned, and driven by one person. . It can be carried out in an open field or in a workshop. The fertilizer machine for composting pig manure produced by Fertilize Factory Machine Heavy Industry is more suitable for the process requirements and action mechanism of microbial fermentation of fresh chicken manure into fertilizer, and can effectively mix viscous chicken manure with straw powder and microbial preparations.

The pig manure turning machine also effectively prevents the generation of odorous and harmful gases such as amine gas, hydrogen sulfide, and vermicompost during the manure fermentation process. It can produce good bio-organic fertilizer and meet environmental protection requirements. During driving, the whole vehicle rides on the pre-stacked long strip of fertilizer base. The rotating knife shaft hung under the frame performs fluffing, mixing, and shifting of the fertilizer base raw materials. After the vehicle passes, it becomes a new strip. Stack pile. A major technological breakthrough of the pig manure turning machine is the integration of the crushing function of the material in the later stage of fermentation.

How does pig manure contain too much water? How to regulate water content in pig manure fermentation?

When pig manure is used to process organic fertilizer, water is an important parameter for organic fertilizer fermentation. When the water content of pig manure is too large, the fermentation time is long, and when the water content is too low, the temperature of pig manure can not reach the fermentation temperature. According to the situation after mixing, appropriate water or materials should be added to control the water content in 40% – 45%, that is, holding the pig manure with hands without water seepage. So how to adjust the water content in pig manure fermentation?

Microbial life activities need to constantly absorb water from the environment to maintain normal metabolism. Moreover, microorganisms can only absorb soluble nutrients, and the composting

materials softened by water absorption are easy to decompose. Therefore, appropriate moisture content is the necessary condition to maintain the optimal activity of microorganisms and the smooth progress of composting fermentation. When the water content is higher than 80%, the water molecules fill the interior of the particles and overflow to the particle gap, which reduces the pores of the reactor and increases the resistance of gas mass transfer, resulting in local anaerobic of the reactor, inhibiting the activity of aerobic microorganisms, and not conducive to the high temperature aerobic fermentation of materials.

However, the water content should not be lower than 40%. If the water content is too low, it will increase the porosity of the heap, increase the water dispersion loss, and cause water shortage in the heap, which is not conducive to the activity of microorganisms and affect the fermentation. A lot of research results show that the limit moisture content of compost is generally 60% – 80%, and the suitable moisture content is 50% – 60%.

Generally, the moisture content of composting materials (municipal solid waste and agricultural waste) can not reach the required moisture content value. In the process of composting, water, sludge, wet pig manure and other animal manure are generally used to adjust the moisture content. If the moisture content of composting material is too high, crushed crop straw, garbage, sawdust and edible fungus waste chaff can be added to adjust the moisture content.
