CATDOLL : CATDOLL: How many cubic meters of biogas can be produced from one ton of cow dung? (Video on How many cubic meters of biogas can be produced from one ton of cow dung?)

1. How much biogas residue and liquid biogas can be produced from 100 tons of cow dung?

100 tons of cow dung can produce 70 to 80 tons of biogas residue and 20 to 30 cubic meters of biogas liquid.

2. How many cubic meters of biogas are produced after fermenting one ton of cow dung?

The amount of biogas produced by each ton of cattle manure is 190-200 cubic meters

Dry cow dung contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract, and 15-30% crude fiber. It has high nutrients and can become high-quality organic fertilizer products after fermentation. It can loosen the soil, improve the compaction of the soil, chelate the trace elements in the soil, and improve the fertility of the soil. Biogas is a gas produced by the decomposition and metabolism of organic matter such as straw, weeds, human and animal feces, garbage, sludge, and industrial organic wastewater under anaerobic conditions through a small amount of anaerobic microorganisms.

3. How much biogas can be produced by one kilogram of feces?

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas. One kilogram of wet cow dung can produce 0.051 cubic meters of biogas (the moisture content of wet cow dung is calculated as 83%). The above data is for medium-temperature fermentation, and the fermentation cycle is about 30 days. The main component of biogas is methane, which accounts for about 60% to 80% of the various gases produced. Methane is an ideal gas fuel. It is colorless and odorless, and it will burn after mixing with a proper amount of air. The maximum heat generation of pure methane per cubic meter is 34,000 joules, and the heat generation of biogas per cubic meter is about 20,800-23,600 joules. That is, after 1 cubic meter of biogas is completely burned, it can generate heat equivalent to that provided by 0.7 kilograms of anthracite.

That is, after 1 cubic meter of biogas is completely burned, it can generate heat equivalent to that provided by 0.7 kilograms of anthracite.

5. How much biogas can be produced from 1 kg of feces?

Based on the feed absorption efficiency in the body, which is about 35% for chickens and 75% for pigs, and the feces moisture content of about 80%, the theoretical biogas production of one gram of dry feed is 135 liters or 0.135 cubic meters. The actual gas production cannot be so high. Calculated at 85%, one ton of chicken manure can produce about 48,900 cubic meters of biogas.

1 kg of pig manure produces 0.42 cubic meters of biogas. It is difficult to determine the concentration of 1 ton of pig manure water, and it is also difficult to determine the biogas produced, so it can only be estimated.

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas. One kilogram of wet cow dung can produce 0.051 cubic meters of biogas (the moisture content of wet cow dung is calculated as 83%).

6. How much sludge can be produced from one ton of cow dung?

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas. So, one ton is 300 cubic meters.

7. How many cubic meters of biogas can be produced from one kilogram of cow dung?

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas.

Dry cow dung contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract, and 15-30% crude fiber. It has high nutrient content and can become a high-quality organic fertilizer product after fermentation. It can loosen the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility.

Biogas is a gas produced by the decomposition and metabolism of organic matter such as straw, weeds, human and animal feces, garbage, sludge, industrial organic wastewater, etc. under anaerobic conditions by a small amount of anaerobic microorganisms.

Additional information:

Note:

1. The feed inlet of the biogas digester must be covered to avoid casualties to humans and animals.

2. It is strictly forbidden to ignite near the discharge port of the biogas tank or the gas pipe port to avoid backfire and fire, which will cause the biogas tank gas to expand violently and explode.

3. Sun protection measures should be taken for outdoor pipelines to extend their service life to prevent weathering, aging and leakage. It is strictly forbidden to light a fire within 5m of a biogas tank.

4. It is prohibited to apply heavy pressure on the biogas tank and its surroundings, and it is prohibited to pile up flammable and explosive materials.

5. It is prohibited to allow all kinds of pesticides and harmful debris into the pool to avoid killing biogas fermentation bacteria and microorganisms and affecting gas production.

6. If there is any malfunction in the biogas tank, biogas stove or accessories, the biogas maintenance personnel should be informed in time and repaired by professionals to ensure safety.
