What is the role of sewage treatment in pig farms for the breeding industry

It is very important that if the sewage from the farm is treated well, it will save the cost of breeding.

The latest technology MBR membrane integrated sewage treatment process can still carry out biological reaction under the condition that the concentration of high-concentration activated sludge MLSS is 2 5 times that of the traditional method, and the sewage rich in many organic components can be differentiated in a short time or in a smaller space, and the biological reaction speed is faster. Because the MBR membrane integrated sewage treatment plant retains a high concentration of activated sludge, the discharge of remaining sludge is reduced to a large extent. In the MBR, the hospital does not need a secondary sedimentation tank, and compared with the traditional activated sludge method, the installation MBR space is much smaller.

It can be used for the expansion of existing equipment, and can also reduce the footprint of new equipment.

Advantages of special sewage treatment equipment for farms.

1. The aquaculture sewage treatment equipment is composed of one or more units connected by on-site connection, which is small in size, light in weight, easy to transport and easy to install.

2. It adopts FRP, carbon steel and stainless steel anti-corrosion structure, which has excellent characteristics such as corrosion resistance and anti-aging, and has a service life of more than 20 years.

3. Save land, no need to build a house, heating and insulation. Maximizes device integration and reduces footprint.

4. No pollution, no peculiar smell, reduce secondary pollution.

5. It is not limited by the amount of sewage, it is flexible and flexible, and can be used alone or in combination with multiple people.

6. The whole processing equipment is equipped with an automatic control unit and a fault alarm device, which is safe and reliable in operation, and generally does not need special personnel to manage it, but only needs to maintain and maintain the equipment in a timely manner, and the management cost is small.

The treated sewage can be used for recycling and reuse. If the biogas digester is used to treat wastewater, the thoroughly fermented biogas liquid also has a disinfection function, which can not only be used to sterilize the barn, but also to mix and give drinking water to livestock.

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.

Pig wastewater contains high concentrations of organic matter, suspended solids, ammonia nitrogen and other pollutants, and its water quality and quantity are greatly affected by the production process season and product factors, so it is necessary to choose a process with strong impact load resistance. Physical, chemical, and biological treatments can be used.

1. Physical treatment methods include the use of grids, precipitation, filtration, etc. It can mainly remove large suspended solids and impurities, feed residues, pig hair and other substances that may cause blockage or wear to pipelines and pumps in sewage.

2. Chemical treatment methods include coagulation, disinfection, neutralization, etc. It can treat soluble harmful substances in pig wastewater, such as acid and alkaline organic compounds and various organic solvents used in cleaning pigsties.

3. The biological treatment method is to use microorganisms to decompose and transform the pollutants in wastewater by using the metabolism of microorganisms themselves under the catalysis of enzymes.

For pig farm wastewater, solid-liquid separation is the most basic step in treatment. Therefore, it is necessary to use pre-treatment to remove most of the solid substances present in the wastewater before formal treatment to ensure that the load of subsequent treatment is reduced. For the liquid part after solid-liquid separation, the anaerobic process is generally used for harmless treatment.

Pig farm wastewater is usually treated by the method of sedimentation, larger pig farms will spare 2 to 3 sedimentation tanks, when the wastewater is discharged into the sedimentation tank, it will be precipitated, filtered, and finally oxidative decomposition, this method is usually widely used, and the effect is also very good.

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.

The biogas fermentation process is mainly used for treatment, which can remove up to 90% of the soluble organic matter. Depending on the size of the farm, the degree of utilization will be different.

Small: It is mainly fermented in the biogas digester and then discharged to farmland or fish ponds.

Medium and large-scale: advanced biogas plants can be used to ecologically recycle the biogas slurry after the excrement is treated, which can be used as farmland fertilizer, or as a power and heat source for farms.

Answer: How to treat the sewage of your pig farm? I think that the sewage from the pig farm has to be drained out, so send a hook or dig it up, and call it the sewage out. The pig's dung is called in the cellar, so that he can flow out of the cellar, so that it is okay.

The sewage of the pig farm should also be treated by the sewage treatment station, and the discharge can only be discharged to the standard, otherwise it will pollute the surrounding environment.

How to deal with pig sewageHow to treat pig sewage? The sewage from pig farming is generally fixed. Manure tanks. It is specially used to store sewage and feces.

The main characteristics of pig farm wastewater are: high concentration of organic matter, many suspended solids, dark color, and contains a large number of bacteria, which makes the NH3-N concentration very high because it contains a large number of animal feces and urine.

The treatment methods can be simply summarized as physical treatment, physicochemical treatment, chemical treatment and biological treatment, and the most widely used is the biological treatment method - microbial sewage treatment of Gandu strains.

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.

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.
