CATDOLL : CATDOLL: How many cubic meters are there in one ton of cow dung (how many cubic meters of soil are there in one ton of cow dung)

1. How much dry cow dung can be fermented from one ton of cow dung?

First weigh one ton, then mix the dry cow dung into mud, find a few 1 cubic meter containers, fill them with it, see how many buckets can be filled, then dry them, and fill them in again until they are full.

That is to say, weigh the weight per unit volume and then calculate it specifically.

2. How many cubic meters are equal to 1,744 tons of cow dung?

1744 tons of cow dung equals 1744 cubic meters, one ton of dung equals 1 cubic meter, and one ton of water equals one cubic meter. Density of water: The density of water is the largest at 3.98℃, which is 1×10³kg/m³. When water is at 0℃, the density is 0.99987×10³ kg/m³. Under normal circumstances, the density of water is 1×10³kg/m³. The mass of 1 ton of water is 1000 kilograms. The volume of one ton of water = 1000 kilograms ÷ 1×10³kg/m³ = 1 cubic meter. One cubic meter of wet dung weighs between 1.5 tons and 2 tons, and the weight varies depending on the water content.

3. How many tons of coal can be produced from 10 tons of dry cow dung?

More than 3 tons.

The calorific value of one ton of dry cow dung is about 2300 kcal per kilogram. One ton, or 1000 kilograms, of dry cow dung has a calorific value of 2300000 kcal, or 2300 kcal.

The calorific value of one kilogram of standard coal is 7000 kcal, and the calorific value of one ton of standard coal is 7000 kcal.

The calorific value of three tons of dry cow dung is approximately 2300x3=6900 kcal, which is close to 7000 kcal.

So, about three tons of dry cow dung can replace one ton of coal.

10 tons of dry cow dung can produce more than 3 tons of coal.

4. How much pig manure is needed to generate 1 cubic meter of methane?

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%). 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.

5. 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.

6. How much land does one ton of cow dung consume?

One ton of cow dung can be used to return about one mu of land, provided that it is well-rotted. In addition, mixing it with agricultural urea is more suitable for plant growth. Well, this is the experience gained by farmers themselves, and I hope you can refer to it. There are many kinds of fertilizers, and chicken manure and sheep manure are also commonly used. These types are the more common commercial organic fertilizers. Chicken manure is applied to bean fields, melons and fruits. Sheep manure is the best for rice fields, corn and rice.

7. How much cooked cow dung can be fermented from one ton of raw cow dung?

Answer: 0.3-0.5 tons of cooked cow dung.

Cow dung is a cold fertilizer because of its fine texture and slow decomposition. How much cooked cow dung can be produced from one ton of raw cow dung? One ton of raw cow dung generally contains 90% water. To make cooked cow dung, the raw cow dung must first be dehydrated to a certain extent. According to general data: one ton of raw cow dung can produce about 0.3-0.5 tons of cooked cow dung. The specific output depends on the actual ingredients and the water content of the cow dung.

8. How many kilograms does one cubic meter of wet cow dung weigh when dried?

Every 3 to 4 cubic meters of wet cow dung can be converted into 1 ton of dry cow dung.

Then, on average, each cubic meter of wet cow dung can be converted into 500 to 667 kilograms of dry cow dung, and a 1-ton dryer can dry cow dung equivalent to 2.5 tons of wet cow dung; that is, one ton. After wet cow dung is fermented, about 3,500 kilograms of dry cow dung can be produced, which is about the weight, because the water content of cow dung is about 65%!

9. How big is a 1-ton septic tank?

One ton of septic tank is equal to 1.2 cubic meters.

The weight of each cubic meter of water is one ton, (2000 jin) The feces are different, among which chicken manure is the lightest, with a specific gravity of about 0.8, 800 kilograms per cubic meter; followed by cow dung, about 900 kilograms per cubic meter, human feces, urine, and pig manure are slightly lower than the weight of water, very close!
