Problems solved by technology

[0002] At present, the main pig house manure cleaning processes in my country mainly include dry manure cleaning, water soaked manure and mechanical manure scraping board, etc. These manure cleaning processes have their own disadvantages: dry manure wastes labor; water soaked manure is easy to form anaerobic fermentation, and produces a large amount of harmful gases , and waste a lot of water resources, which brings troubles to the follow-up sewage treatment; mechanical manure scraping board is currently an ideal technology for cleaning manure in pig houses, but it has the disadvantage of unclean manure scraping
[0003] At present, my country's pig manure resource utilization mainly includes biogas projects and aerobic composting to produce fertilizers. The disadvantages are that biogas fermentation is affected by seasonal temperatures, and biogas slurry treatment is difficult; Nitrogen loss
[0004] Therefore, it is necessary to find a new manure treatment process to solve the problem of difficult manure treatment in large-scale pig farms

Embodiment Construction

[0023] Such as figure 1 Shown, a kind of method for processing pig farm excrement in fermented bed outside house, specifically:

[0024] (1) Build a fermentation bed outside the pig house. The pig house is connected to the rain and sewage diversion tank, sedimentation tank, and sewage ditch respectively, and the sewage ditch is connected to the fermentation bed through the septic tank; 2 The standard production of each head, the width of the fermentation bed is 4.5-6.5 meters, the length depends on the needs, ranging from tens of meters, the shoulder height is 1.4-1.5 meters, the top height is 2.4-2.5 meters, the wall height is about 1 meter, and the tube spacing is 1 Rice, covered with plastic film, made into a cuboid according to the style of vegetable plastic greenhouses; 2 Effective volume construction of / 100 heads;

[0025] (2) Laying of fermentation materials: Lay the fermentation materials evenly in layers from bottom to top in the order of litter, bacteria, excremen...

Abstract

The invention discloses a method for treating pig farm feces through an outside fermenting bed. The method includes the steps of constructing the fermenting bed outside a pig farm, and uniformly laying fermentation materials on the bottom of the fermenting bed according to the order of a pad material, bacteria, manure and rice bran, corn flour and lees from top to bottom; plowing and harrowing, conducting ventilation, supplementing bacteria at regular intervals according to the quantity of 30 g / m2 on the fermenting bed, and therefore maintaining the high activity of the fermenting bed; collecting feces in the pig farm to a cesspool, uniformly spraying on the pad material of the fermenting bed through a feces management system, making the faces decomposed to form small molecule matter and meanwhile absorbed by profitable strains for growth and reproduction of the bacteria, and changing the manure into an organic fertilizer through the synergistic fermentation of the pad material and feces collection matter. According to the method, the pig farm and the fermenting bed are separated and isolated to avoid mutual effects and eliminate disease transmission potential, and the method has the advantages of easy construction, convenient operation, thorough collection and treatment of feces, and remarkable effects of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the treatment of manure from pig farms, in particular to a method for treating manure from pig farms in an outdoor fermentation bed. Background technique [0002] At present, the main pig house manure cleaning processes in my country mainly include dry manure cleaning, water soaked manure and mechanical manure scraping board, etc. These manure cleaning processes have their own disadvantages: dry manure wastes labor; water soaked manure is easy to form anaerobic fermentation, and produces a large amount of harmful gases , and waste a lot of water resources, which brings troubles for subsequent sewage treatment; mechanical manure scraping board is currently an ideal technology for cleaning manure in pig houses, but it has the disadvantage of unclean manure scraping. [0003] At present, my country's pig manure resource utilization mainly includes biogas projects and aerobic composting to produce fertilizers. The disadvantages are ...
