Is it feasible to use biogas slurry to flush the pig barn in pig farms with scarce water resources?

Yes, but you should pay attention to the method and not implement it blindly at will.

Specific methods: 1. After simple filtration of biogas slurry in the secondary anaerobic fermentation tank, the pig house is flushed with a sewage pump, and the time of flushing is short, the water is large and the time is short, and the pigs are accustomed to drinking biogas slurry and playing, which has no effect on the pigs, and the time for each lap is less than 1 minute, and finally the biogas slurry and pig manure flow back into the first-class anaerobic fermentation tank together.

2. Use biogas to heat the water to 50 degrees, rinse it with high pressure, and use water below 35 degrees in winter, so that the pig will cause emergency and diarrhea, and the water consumption is less than one-fifth of the conventional flushing, and the time for each lap is dozens of seconds.

3. According to one kilogram per five square meters, the mixed disinfectant is atomized and disinfected with a high-pressure gun, and the temperature of the disinfectant is 38-40 degrees.

Advantages: good cleaning and disinfection effect, no manual dry manure, saving labor, and pigs are very healthy.

Disadvantages: The temperature of the pig house is required to be 20-22 degrees, and the ventilation effect is good, and it cannot be cooled strongly.

Note: The temperature is not enough, the weather is too cold to wash the circle with water; Poor ventilation, slow drying, can not be flushed with water. This method is used in large pig houses, and the advantages of less piglet manure are not obvious.

It should not be appropriate, mainly in terms of hygiene and epidemic prevention.

You can raise pigs with beans on your phone.

There are a lot of pig breeders in it, see what they do.

Hope it helps,

Use water where it is needed, and reduce it where it is not necessary, after all, water is very important, and pigs need a lot of water in the process of growth.

Pig farm water is more serious, try to save, we can install wells in pig farms, try not to use human drinking water, so that the rational use of water resources.

Pay attention to the quality of water when taking and using water. Ensure the safety of drinking water. The disinfection and flushing water of the pig farm is very large, occupying 65% of the total water supply, and the pigsty and manure should be cleaned regularly every day to improve the environment of the pig farm, and the water should be reasonably distributed, otherwise it may cause a great waste of water.

Water is very important to pigs, especially large-scale pig farms, mastering scientific water use methods, can ensure the economic benefits of pig farms, and obtain higher profits.

1.According to the pig farm wastewater treatment 1, pig farm wastewater water quality characteristics and drainage conditions, a high separation section can be set up before the wastewater treatment process, the initial separation of manure and wastewater, reduce the amount of wastewater treatment, generally the separated pig manure and manually removed manure after accumulation and fermentation as organic fertilizer sales. 2.

The separated wastewater flows into the sedimentation tank and the regulating place by itself, and after the wastewater is settled, acidified and balanced, part of the hydrolyzed sludge is removed and discharged into the sludge drying tank. 3.Generally, after the wastewater from the pig farm rises through the pump, it flows into the discharge anaerobic reaction tank and then undergoes first-class biochemical treatment, which will produce biogas, which can be used for power generation, heating, etc.

4.After the wastewater sedimentation sludge and sludge drying, the composting field and the excrement removed by hand are piled up and fermented to become compound fertilizer.

2. Manure treatment of pig farms 1. The return of manure to paddy soil with fertilizer can improve the soil and increase crop yield, which is directly related to the way of returning manure and wastewater to the field and the process of cleaning powder. At present, some countries can use pig water to rinse manure, so that after the manure water is fermented, it can be applied to the soil, plus sowing or mechanical rupture, and pigs are raised by cleaning pig manure, and the manure can be treated by the self-purification ability of the soil, and the soil can purify the manure while absorbing fertilizer, reducing the cost of treatment. 2.

In the process of manure maturity, the general temperature can reach 50 70, which can well kill most of the eggs, weeds, microorganisms, parasites, etc. in the manure.

3. The manure composting method stacks the raw materials mixed on the cement floor, cement tank and plastic film into the shape of a growth strip, with a height of meters and a width of meters, and the length depends on the farm. 4.Manure to biogas power generation can be used to produce gaseous manure wastewater.

Biogas is an anaerobic microorganism that breaks down carbonaceous organic matter in manure and then produces a gas mixture. Biogas can be used as a new source of energy, as fuel, lighting, power generation, etc. The fermented digestate can be used as fertilizer, and the slurry can be discharged directly into the pond for biological treatment.

5.Manure can be used as aquatic plant feed to use organic wastewater, can be planted with aquatic plants such as fine green weed and water hyacinth, generally fine green weed has resistance to medium concentration of feces, gourd has resistance to high concentration of feces, high concentration of organic manure in the water hyacinth pool can play a role in absorption and purification after about 7-8 days.

Watering the ground. Because the wastewater from pig farms is a natural fertilizer, it is the best choice to use it for watering, and it can also save a lot of fertilizer money.

Pig sewage can use its physical gravity or mechanical force to make it go through the grid, sedimentation, filtration, remove suspended solids, impurities, feed residues, pig hair and pig urine and other substances in the sewage, which can be used for irrigation of farmland and green space, enter the fish pond to raise fish, and can also be reused to flush the livestock house when conditions permit.

If it is a pollutant sewage with relatively large particles, the pig farm can use the method of sedimentation, through the early precipitation, and then filtered, which is easy to discharge, and sedimentation is usually the most widely used method of sewage discharge.

Simple, just use the waste water ** machine. The treated water is similar to clean water, and can be directly discharged, irrigated, and fish raised.

Ordinary solar greenhouses, high-standard spring and autumn arches and 500 insect repellent net greenhouses have been built. 4 fully automatic intelligent multi-site solar greenhouses of 15,000 square meters; 10,000 ecological pig farms, 5,000 coastal green ecological pigs, 1 new 500 cubic meters of marshland, with an annual output of 10,000 cubic meters of biogas. The agricultural park produces biogas, which is used as energy to meet the park's daily needs such as lighting, heating, and boiling water.

Biogas slurry and biogas residue are used for the planting of vegetables, flowers and fruit trees in agricultural parks, and biogas slurry is used for liquid fertilizer, which can be sprinkled on the foliage surface and can also be topdressed with water. The swamp residue is used for top dressing in the park and for the precise production of high-quality organic fertilizer, which saves 600,000 won in fertilizer and pesticide energy every year.

The comprehensive utilization of biogas directly links biogas with agricultural production activities, carries out off-season production, improves grass temperature, breeds well, uses biogas to increase warehouse temperature, increases warehouse carbon dioxide concentration, improves crop growth and living conditions, promotes photosynthesis, provides harmless fertilizer, and becomes an important means to develop ecological agriculture and increase enterprise income. The products of biogas fermentation are not only living energy, but also fertilizers, feed, and "quasi-pesticides", which are used for crop soaking, preventing crop diseases and pests, and improving crop yield and quality. Biogas slurry contains a large amount of humic acid and trace elements required by a variety of crops, these nutrients penetrate into the seed coat during the soaking process, are absorbed by the seeds, promote the recovery of the purest seeds and embryos, accelerate the conversion of seed nutrients, sprinkle into the soil after the seeds germinate, and the nutrients absorbed by the seeds are released, which are used by the seeds and seedlings to promote growth and improve resistance.

Biogas slurry is anaerobic fermentation, there are no parasite eggs and harmful hospital microorganisms, so the biogas slurry is rich in nutrients, and the safe biogas slurry can not only feed pigs, but also improve the economic benefits of pig farming. A kind of biogas slurry contained in it is called bacillus, which can parasitize in the intestines of pigs, and at the same time make many digestive enzymes to promote the decomposition of fiber in the feedThe biogas slurry produced by the swamp for more than 1 month of normal gas production can be used to feed the biogas slurry to pigs, and the biogas slurry must produce normal gas after 1 month after the large exchange before it can be used.

The color of the biogas slurry should be dark brown and there should be no smell of manure.

Swamps cannot be used with dead animals and pesticides, and domestic water cannot be accessed. When collecting the slurry, be careful to throw away the debris and leave the upper layer of green slurry. The biogas slurry is usually fed to pigs for 2 months above 20 kg, the effect is better, and the weight gain is obvious.

Do not feed piglets less than 2 months old or piglets weighing less than 20 kg at 2 months of age. The gastrointestinal adaptation is not good, but it grows slowly. Farrowing sows are best not to be fed biogas slurry during lactation.

The feed biogas slurry is relatively fixed and cannot be changed at will, so as not to cause stress reactions such as diarrhea. In summer, there is a little smell of ammonia in the biogas slurry, which can diffuse for 15 20min, allowing the ammonia to escape and feed, but if it is left for too long, it is easy to get infected with bacteria.

Biogas slurry biogas residue pig technology is the use of biogas slurry biogas residue as additives for pig raising technology, this natural additive, can speed up the growth of pigs, and after the verification of the agricultural sector, so that the pigs fed, all indicators are qualified, the meat is delicious, so we can rest assured that we can use this technology to raise pigs.

Increasing biogas slurry in feed can enhance the pig's appetite, make the fur shiny, reduce diseases, and gain weight quickly. When raising pigs with biogas slurry, take out an appropriate amount of middle layer biogas slurry from the outlet of the biogas digester with a manure spoon and other containers, put it in the feed and stir. The amount of biogas slurry added should be divided into three stages according to the conditions of pigs.

When the concentration of biogas slurry is too large, the amount of biogas slurry used should be reduced. It is strictly forbidden to use the biogas slurry in the normal fermentation of biogas, and the sows should be fed less biogas slurry after weaning, and also pay attention to deworming.

Because these substances can be turned into methane, and fertilizers can be produced, the cost is low.

The biogas slurry and biogas residue must be very nutritious, not too single, and the town can also be filled with biogas slurry in the water, and it is often sterilized and disinfected, and there are regular insect repellents, and the temperature should also be suitable.

Choose a good breed of pigs, choose good feed for feeding, maintain good ventilation, timely disinfection and sterilization, feed a little life support hormone, ensure sufficient sunlight, timely file jujube vaccine, and observe the growth and development of pigs.

Pig farm wastewater is usually separated by certain chemical reactions to effectively remove pollutants from the wastewater.

This wastewater is separated by chemical reaction and mass transfer, and after precipitation, it is eradicated by employees.

Pig farm wastewater generally removes pollutants from wastewater through chemical reactions.

Pig farm wastewater is separated by mass transfer through certain chemical reactions, which effectively removes contaminants from the wastewater.
