Zero-pollution dry domestic-animal-fowl raising method and apparatus

Abstract

The present invention discloses a dry livestock poultry raising method with zero pollution and its installation. It includes the following measures: regularly feeding feed, water, cleaning livestock farm and house and excreta treatment, and the described drinking water is an activated water obtained by utilizing general water and making it undergo the process of resonance treatment by means of resonance device capable of transmitting far infrared ray and adding trace elements in it, said livestock farm and house can have raising zone and enclosure for defining raising zone, said raising zone can be divided into rest-moving zone and excretion zone, and the excreta treatment includes decomposition, drying and modification, etc.

Description

technical field [0001] The invention relates to a dry raising method of livestock and poultry, in particular to a pollution-free dry raising method of livestock and poultry. Background technique [0002] In recent years, my country's livestock and poultry breeding industry (such as: duck industry, pig industry, etc.) has gradually entered a large-scale enterprise operation. , especially the pig manure and urine produced by the pig industry has the greatest impact on environmental pollution [0003] In the process of raising pigs, a large amount of water is usually used to directly flush the pig house, thus producing a large amount of pig manure and urine waste water. If the pig manure and urine waste water is not properly treated and directly used or discharged, it will have the following impact on the surrounding environment : [0004] 1.1. Water pollution: [0005] Pig feces and urine contain a large amount of organic matter and organisms. When they decompose, they will ...

AI Technical Summary

Problems solved by technology

[0004] 1.1. Water pollution:

[0005] Pig feces and urine contain a large amount of organic matter and organisms. When decomposed, they will consume dissolved oxygen in the water, resulting in eutrophication of the water body, disrupting the ecological balance, and hindering the normal drainage and flood control functions of the river.

At the same time, the water source of tap water is polluted by pig feces and urine waste water, which will lead to odor in the tap water for drinking

[0006] 2.2. Poison crops and fish:

[0007] If pig manure and urine wastewater is directly mixed into irrigation water or fish pond water, the excess nitrogen contained in it will cause deformed crop growth, reduce yield, and cause fish death

[0008] 3.3. Harm to environmental sanitation:

The feed mainly used to raise livestock and poultry is formulated according to the amount of essential protein required, but when the content of other non-essential protein is too high to be digested by livestock and poultry, these excess proteins will be directly excreted. At this time, when the microorganisms in the pig excrement decompose these residual nitrogen-containing compounds (such as: protein), they will produce unpleasant ammonia gas, causing the entire pig house environment to be filled with an unbearable odor

The poor breeding environment will not only have a negative impact on the growth of livestock and poultry, but will also affect the quality of the surrounding environment and cause complaints from nearby residents

[0017] On the other hand, during the composting and decomposing of pig manure and urine sludge, it is located in an open fermentation tank. During the long-term fermentation process of about three months, the situation of foul odor will inevitably be aggravated, resulting in secondary environmental pollution. Pollution

[0018] 2.2. It is difficult to treat a large amount of pig manure and waste water, which increases the cost of feeding, and the willingness of pig farmers to deal with it is not high:

[0019] It is very difficult to deal with a large amount of pig manure and urine wastewater produced by cleaning pig houses. For large-scale pig farmers, since a considerable amount of pig manure and urine wastewater will be generated, it is absolutely necessary to spend treatment costs to further properly treat pig manure and urine wastewater

However, for small and medium-scale pig farmers, although the amount of pig manure and urine wastewater is relatively small, additional treatment will increase the cost of feeding, and even cause a dilemma that is not economically beneficial. In addition, the site area is insufficient and cannot be used for composting. Therefore, the willingness of small and medium-sized pig farmers to treat pig manure and waste water is relatively low, resulting in an endless stream of incidents of secretly discharging pig manure and waste water and being punished

[0020] 1.3. The composting conditions of pig manure and urine sludge are difficult to control, resulting in too long fermentation time:

[0021] When composting pig manure and urine sludge, if the sludge dehydrator is used or water regulators are added to adjust the water content, it is quite easy to make the pig manure and urine sludge into a paste, so that the water in the composting process is not easy to lose. Prolong the fermentation period and affect the fermentation effect

[0022] Furthermore, pig feces and urine sludge has a high water content and is quite difficult to handle. If the water content is not adjusted properly, resulting in too high water content (above 68%), subsequent air supply will be difficult, and the fermentation temperature can only be maintained at 30-30%. 40 ℃, resulting in relatively prolonged compost fermentation time, etc., and even the pig manure and urine sludge must be cleared out of the fermentation tank several times and exposed to sunlight to maintain the subsequent normal fermentation.

Therefore, due to factors such as difficult control of fermentation conditions, long fermentation period, and the need for manual overturning, a large amount of manpower must be spent on site monitoring and processing, which significantly increases the time-consuming and cumbersome process of composting pig manure and urine sludge
