A kind of pig breeding feces and urine removal process

Abstract

The invention provides a removing process for manure and urine during live pig breeding. The process comprises the following steps: drinking water is provided by adopting a bowl-type water-saving water drinker; the ground surface of a pig house uses a manure leaking plate, and the lower side of the manure leaking plate is provided with a manure tank; the manure tank comprises a scraping channel and a urine guiding pipe; the scraping channel is inclined from the edge to the middle part, has a slope degree of 25-45 degrees and forms a funnel shape, and the bottom of the center of the scraping channel is provided with the urine guiding pipe; the surface of the scraping channel is treated by an anti-slip agent, and has a friction coefficient of 0.8-0.9; and the contact part of a manure scraping plate with the scraping channel employs a rubber material, and has a width of 1-3 cm. According to the removing process for the manure and urine during the live pig breeding provided by the invention, nutrient ingredients in manure are maintained, and the nutrient ingredients do not flow to urine; excrement quantity is not increased, and subsequent treatment costs are low; and the microclimate environment in the pig house is maintained, humidity is reduced, odor is reduced, and health of live pigs is facilitated.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a process for removing excrement and urine from pig breeding. Background technique [0002] The rapid development of the large-scale pig farming industry has solved the problem of ensuring the supply of pork non-staple food for urban and rural residents, but the discharge of feces and sewage from large-scale pig farms has also caused serious pollution to the rural environment. In order to solve the problem of feces and sewage discharge reduction in large-scale pig farms, the traditional cleaning methods for pig farms generally use manual feces removal, which is labor-intensive, expensive, and has poor cleaning effects. Generally, it can only reduce emissions by 40%-50% ; If the water-soaked excrement cleaning management mode of the leaking excrement floor is adopted, it can only reduce the discharge of fecal sewage, but cannot reduce the total amount of organic pollutants.

Problems solved by technology

One is flushing with water first and then post-processing, washing out excrement and urine together. The amount of excrement and rinsing water is large, and subsequent biochemical treatment or farmland digestion is generally used, and the cost of post-processing is high.

One is the same-bed fermentation method. The problem is that the fermentation bed needs to be turned regularly, and the "dead bed" must be prevented. The cost of the fermentation bed is high, and toxic and harmful gases will be generated when the bed is turned, which will affect the health of the pigs above the bed.

[0006] The above method of separating wet and dry feces and urine has a slope that is too small, and urine and feces cannot be separated well due to the water storage property of the feces itself. Fluid drainage is not smooth
