Currently, pig farming accounts for a large proportion of the livestock industry in Vietnam. The strong development of the pig farming industry has brought with it many consequences for environmental issues. Pig farming that is not planned properly or properly in the long term will cause severe environmental pollution and loss of aesthetics. So, how to treat pig farming wastewater to limit negative effects? The article below, Duc Binh microbiological products will reveal help you.
1. Current status of pig farming and environmental problems of wastewater?
In recent years, the pig farming industry has accounted for a large proportion and developed at a dizzying rate. However, the question is how to treat waste so as not to affect the living environment?
Current status of livestock farming and how to treat pig farming wastewater
Livestock wastewater affects the environment and human health. It will pollute water sources, soil, air and agricultural products. It is also the indirect cause of gastrointestinal, respiratory and intestinal-related diseases in humans.humans.
Therefore, if there are no timely measures to prevent and handle, the consequences will be even more unpredictable. If the livestock environment is polluted, disease-causing viruses will multiply and penetrate the animals’ bodies causing epidemics of blue ear disease and foot-and-mouth disease, causing mass deaths of pigs. More dangerously, pig diseases will affect human health. So, how to treat pig farming wastewater?

2. What are the characteristics and requirements for wastewater treatment?
Pig farming wastewater is wastewater that has the potential to pollute the environment because of its high organic matter content, suspended residue containing N, P, and disease-causing organisms. Therefore, the form and process of treating pig farming wastewater must be appropriate and correct so as not to affect the farming process. Criteria for selecting a wastewater treatment process for a pig facility depends on many factors including:
Organic and inorganic substances
In pig farming wastewater, inorganic and organic substances account for up to 70%. Most organic substances are always easy to decompose and account for 30% including soil, sand, salt, urea, SO42
Nitrogen and phosphorus
According to livestock experts, livestock’s ability to absorb N and P is very poor. Therefore, when they are not absorbed, they will be excreted in feces and urine. That’s why pig farming waste will have very high amounts of N and P. Normally, the N content in livestock waste is from 600-1100mg/l and P is from 40-100mg/l
Disease-causing microorganisms
Since it is livestock wastewater, it will contain many bacteria, germs and viruses or larvae and worm eggs. These are the agents that cause some extremely dangerous diseases for humans. Therefore, the Ministry of Natural Resources and Environment has been harsh and strict on wastewater treatment livestock before discharging into the environment

3. What are some ways to treat pig farming wastewater?
As mentioned above, livestock wastewater in general and pig farming wastewater in particular, if not treated properly will cause many serious problems. Because pet feces will contain many substances such as N, P, Cu, Nickel and harmful microorganisms. These organisms not only affect the air and water environment but also pollute the soil. Soil is an important resource in the growth and development of livestock.
Therefore, people need to have a way to treat pig farming wastewater so as not to disturb soil fertility and crop quality. Follow along to learn some widely used and effective pig farming wastewater treatment methods below:
The wastewater treatment system needs to be fixed promptly
4. How to treat livestock waste with Biogas
technology
How to treat pig farming wastewater with Biogas is widely used on large-scale livestock farms. Biogas digesters are widely used and popular because they help reduce odors and avoid water pollution. Besides, it also produces chemical emissions that are fully utilized in making gas and saving other energy use
Currently there are 3 popular types of biogas cylinders: biogas tanks with fixed lids, built-in tanks with floating lids and polyethylene biogas bags. Each type will have its own advantages and disadvantages, so you can depending on your situation and husbandry process to handle it accordingly
In addition, in the biogas tank there is also the impact of high-speed microbial products and anaerobic microorganisms, so they easily decompose in wastewater. This method not only helps treat pig farming wastewater but also produces Biogas to serve daily needs.
How to treat swine wastewater with biogas technology
Not only that, the tunnel also has a wastewater disturbance system that will help remove sediment and create the most thorough conditions for CH4 gas generation. The biogas mixture produced includes gases such as: CH4 accounting for more than 60%, CO2 gas accounting for more than 30% and some other compounds.
A main function of biogas in swine wastewater treatment is to treat organic matter, reduce the amount of toxic gases generated, destroy dangerous pathogens in water and save costs because it can create artificial gas
So, what happens when the biogas tank is full? How to prevent overflow, break the black film, increase gas and deodorize the biogas tank:
- 1 package of 200gr treats 3 – 5 m3 of tank
- Mix 1 package of EMZEO barn with 5 liters of clean water and pour into biogas tank
- Once a month
Treating waste by composting
Treating pig farming waste with organic composting is using only plant waste and animal manure. Through the direct or indirect action of microorganisms, all kinds of waste are decomposed, creating finished products is a nutrient-rich fertilizer for plants.
Composting using this method is very simple and easy. Manure is composted through natural fermentation or using probiotics to speed up the fermentation process. The method of composting organic fertilizer from pig farming waste applies mainly to small barns. If you want to apply it to large livestock farms, you must invest in initial facilities.
The process of treating waste by composting
When applying the process, you will destroy dangerous pathogens and can decompose dead animal carcasses thanks to the composting process. Compost contains humus which loosens the soil and increases mineral absorption for plants. Besides, it will not affect the environment or humans, but will also have a good effect on the biological and physical properties of the soil.

Treatment of pig farming waste with UASB tank system
UASB tank system is widely used in pig waste treatment because it saves space and is effective. In the reverse filter tank through the UASB anaerobic sludge bed, organic waste in wastewater will be treated in the anaerobic activated sludge layer at the bottom of the tank.
Gas formed during anaerobic digestion in the sludge layer will stick to the suspended sludge. Once adhered, they will separate when they collide with the air barrier. The sludge particles will fall to the sediment layer at the bottom of the tank and the collected gas will return to the gas tank.

Advantages of the UASB tank system
Why is waste treatment with the UASB tank system used so much? Surely there will be many questions about this issue. Below are some reasons as well as advantages of the pig farming wastewater treatment method to answer for you:
- The UASB tank system is large so the amount of sludge in wastewater is completely retained, so it will not pollute the water and soil environment.
- UASB tanks do not need a primary sedimentation tank before being put into the biological system.
- Highly efficient and strictly processed
- Save space
Disadvantages of the UASB tank system
Besides the advantages of the UASB tank system mentioned above, there will also be some disadvantages such as:
- High technical requirements for construction and construction because it requires professional handling to not affect the environment
- Price is more expensive than conventional tanks.
Treating waste with biological products
For a long time, people have used probiotics added to wastewater to reduce pollution. Before that, biological products were imported from abroad so the cost was high and it was not always possible to buy. Currently, biological products are produced domestically, so buying and using them has become easy.
Waste treatment with biological products
Current biological products are quite rich and diverse, suitable for the natural conditions of our country. Using the product is simple and easy, people can use it directly in wastewater and barns to reduce odors and clean barns.

Waste treatment with a biogas tank covered with HDPE plastic tarpaulin
If livestock farming is on a small and medium scale, using a biogas digester is appropriate. However, if livestock is raised on a large scale and a large amount of wastewater is generated, the concrete biogas tank will certainly not have enough capacity.. Therefore, people have created tunnels covered with HDPE tarpaulin. The structure of the HDPE tunnel has a waterproof membrane, so the inverting effect helps waste decompose faster.
In addition to being applied to the HDPE tarpaulin-covered pig farming wastewater treatment system, it is also applied through many systems. Not to mention wastewater treatment for wine and beer production or the production of cassava starch and other types of livestock.
Not only that, the structure of the HDPE tunnel will prevent situations such as clogging of the drain and inlet pipes and can automatically remove scum effectively and easily. Another thing is that the tunnel has the best gas production efficiency, so the tunnel temperature is high and will create anaerobic capacity, leading to guaranteed emissions.
