How can I speed up fermentation in a digester?

Increase the fermentation temperature of the digester.

, birds, dung, garbage, pour it in.

Heating, sealing tightly, adding acid, bacterial buds, etc.!

Solid-liquid zonal fermentation of domestic sewage and garbage can meet the needs of harmless treatment of domestic sewage and biogas production at the same time.

The development of rural biogas provides new opportunities for rural economic development, farmers' income and expenditure reduction. The old biogas fermentation technology has the problems of difficulty in building ponds, difficult management and difficult to exert benefits. Saving and utilizing resources, advocating low-carbon life, developing ecological recycling agriculture, solving rural environmental pollution, developing green energy, and biogas construction will play a more significant role.

Precautions and key points for dry and wet fermentation:

Adequate inoculum should be available. After that, before the new tank is loaded, it is necessary to collect the biogas residue and biogas slurry in the old biogas digester, the black sediment at the foot of the manure pit, the pond mud, the sludge from the urban sewage ditch, and the sewage and sludge from the food factory, winery and slaughterhouse, which are rich in biogas bacteria and are good inoculums. The amount of one of the above inoculums should be 10%-30% of the fermentation raw materials.

Mix the inoculum and fermentation raw materials evenly, add them to the pool together, and add water to seal the pool in time. The water added to the biogas digester can be selected in turn, such as biogas fermentation broth, domestic wastewater, river water or pond water, etc., and well water can also be used, but tap water should not be used as much as possible. Industrial wastewater containing toxic substances cannot be used.

Biogas fermentation, also known as anaerobic digestion, refers to the process in which various organic matter is decomposed and transformed by various biogas fermentation microorganisms under anaerobic conditions, and finally biogas is generated.

There is no essential difference between wet and dry fermentation and wet fermentation. The so-called dry and wet fermentation refers to the fermentation process with a dry matter concentration greater than 18%. The dry matter concentration of a normal household biogas digester is generally not greater than 12%.

However, the attention to be paid to dry and wet fermentation is: 1. To prevent the fermentation raw materials from being acidic; 2. There should be enough fermentation inoculum. Otherwise, it is easy to lead to fermentation failure.

1. Create good conditions for microorganisms, so that they can survive and reproduce. First of all, the biogas digester should be closed, and the fermentation of organic matter into biogas is the result of the activity of a variety of anaerobic bacteria. Therefore, it is necessary to create an anaerobic environment for anaerobic bacteria to operate.

When building a biogas digester, it is necessary to pay attention to the isolation of air, which is not breathable and does not seep water. Count.

2. The biogas digester should be maintained at 20-40 degrees, and the gas production rate is the highest at this temperature.

3. The biogas digester should have sufficient nutrients. In order for microorganisms to survive and reproduce, they must absorb nutrients from fermented materials. In the fermentation raw materials of biogas digesters, human and animal manure can provide nitrogen, and cellulose such as crop straw can provide carbon.

4. The fermentation raw materials should contain an appropriate amount of water, and the water content of the fermentation raw materials in the biogas digester is about 80%, and too much or too little is not good for gas production. Remainder.

5. The pH value of the biogas digester is controlled between .

To improve the fermentation efficiency of biogas! The main sliding cherry blossoms have the following aspects: First, it is necessary to create good conditions for microorganisms, so that it can survive and multiply.

A biogas digester must meet a variety of conditions. First of all, the digester should be sealed. The fermentation of organic matter into biogas is the result of the activity of a variety of anaerobic bacteria, so it is necessary to create a nucleus of anaerobic bacteria.

Kiss will be happy to answer for you! The fermentation room of this blue pond of the biogas tomb cannot be connected together, and the fresh fermentation raw materials are fermented through the feed port and the feed pipe into the main fermentation pool, and the residue after fermentation flows out through the discharge room and the discharge port. In this way, it is constantly entering and exiting at the same time, so as to ensure the normal operation of the biogas digester.

If the feed pipe and the discharge room are built together, when a small amount of material is discharged, the fresh fermentation raw materials may be taken out, so that the raw materials can not be fully fermented, the utilization rate and gas production rate of the ruler raw materials are reduced, and it is not conducive to sedimentation and killing the germs in the raw materials and the parasite eggs in the feces, which will seriously affect the sanitary effect of the biogas digester, and will also have adverse effects on the comprehensive utilization of biogas fermentation residues. Therefore, when building digesters, the fermentation rooms must be separated and placed in symmetrical locations along the edge of the digester as far as possible.

Summary. Fresh fermentation raw materials are fermented through the feed port and feed pipe into the main fermentation pool, and the residue after fermentation flows out through the discharge room and the discharge port. In this way, it is constantly entering and exiting at the same time, so as to ensure the normal operation of the biogas digester.

If the feed pipe and the discharge room are built together, when a small amount of discharge, it is possible to take out the fresh fermentation raw material, make the raw material can not fully ferment, reduce the utilization rate and gas production rate of raw material, also is not conducive to sedimentation, kill the pathogens in the raw material and the parasite eggs in the feces, this can seriously affect the sanitary effect of the biogas digester, and also can produce adverse effects on the comprehensive utilization of biogas fermentation residue. Therefore, when building a digester, the feed and outlet lines must be separated and placed as symmetrically as possible along the edge of the digester.

Therefore, when constructing a digester, the feed and outlet lines must be separated and placed in a symmetrical position along the edge of the tank as much as possible.

No, dear.

If my fermentation room is not enough, but the maximum is 10 cubic meters.

What am I going to do.

You can separate it.

How to separate? You use a baffle.

or cement. This means that for example, my total area of 100 is divided into 10 small areas of 10 pairs of parents. Good.

Let's say that in the end I use the total volume or the separate volume when I calculate it.

Total volume.

Biogas is produced by the decomposition of a variety of microorganisms (collectively referred to as biogas bacteria) under the conditions of isolating the air and maintaining a certain water content, temperature, pH weight, etc. The process by which biogas bacteria decompose organic matter to produce biogas is called biogas fermentation.

This is the basic principle of biogas production, the anaerobic mechanism.

The meaning of biogas: biogas is a kind of combustible gas produced by microbial fermentation of organic substances in an anaerobic environment under certain temperature, humidity and pH conditions. Since this gas is first found in swamps, lakes, ponds, people call it biogas.

Composition of biogas: Biogas is a gas mixture, its main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and some other components. In the composition of biogas, the combustible components include methane, hydrogen sulfide, carbon monoxide and heavy hydrocarbons. Non-flammable components include gases such as carbon dioxide, nitrogen, and ammonia.

In the biogas composition, the methane content is 55% 70%, the carbon dioxide content is 28% 44%, and the average hydrogen sulfide content is.

Biogas fermentation is the use of microorganisms to live and multiply in a state of lack of oxygen

Necessary for respiration.

The decomposition of high-energy capacitive organic matter into simple low-energy components, thereby releasing energy for metabolism, is essentially the process of material metabolism and energy metabolism of microorganisms.

Fermentation refers to the process of preparing the microbial bacteria themselves, or direct metabolites or secondary metabolites, with the help of the life activities of microorganisms under aerobic or anaerobic conditions.

Fermentation is sometimes referred to as fermentation, and its definition varies depending on the occasion in which it is used. Fermentation usually refers to a certain decomposition process of organic matter by living organisms. Fermentation is a biochemical reaction that humans were exposed to earlier, and is now widely used in the food industry, biology and chemical industries.

It is also the basic process of bioengineering, i.e., fermentation engineering. Research into its mechanism and process control continues.

Biogas fermentation is the process of material metabolism and energy metabolism of microorganisms in order to obtain the energy required for respiration when microorganisms live and reproduce in a state of lack of oxygen, and decompose high-energy organic matter into simple low-energy components, so as to release energy for metabolism.

3.Principle: The basic principle of biogas fermentation, the essence of fermentation is a physiological process of microbial metabolism and energy metabolism, which is divided into three stages! 1. Liquefaction stage 2. Acid production stage 3. Methane stage: The significance of biogas digester construction 1.

There are many types of organic matter in fermentation raw materials, such as livestock manure, crop straw, food processing waste and wastewater, which are degraded into methane and other substances by biological bacteria under anaerobic conditions.
