What are the main chemical elements that make up human?

Carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, sodium, etc.

It's about the same as the composition of the human body.

Feces, animal feces, etc. do not belong to domestic garbage, so naturally there is no need to use dry garbage, lead rock wet garbage, hazardous garbage, and can be classified.

Animal waste in outdoor public places should be packed in paper or plastic bags, and if possible, take home and flush the feces down the toilet, and contaminated paper and plastic bags should be placed in dry garbage.

If it is inconvenient to dispose of it separately, you can put the bag into the dry trash can and tie the bag tightly to avoid affecting the sanitation operation on the way to clean and transport.

It is recommended to put cat feces wrapped in cat litter into dry garbage cans, and pay attention to the dry garbage cans in the community, which should be tightly pocketed to avoid affecting sanitation operations during the cleaning process.

Pet feces should not go into the garbage disposal system, but should go into the city feces disposal system.

Garbage disposal in life seems to be a trivial matter, but it is actually a very big thing, garbage sorting can effectively reduce the pollution of garbage to the environment, and can also reduce arable land.

Garbage disposal can turn waste into treasure. A lot of garbage in our country contains some decantatable substances, which have been used to become effective resources for the benefit of mankind.

Garbage disposal can reduce pollution. There are many ways to dispose of garbage in our country, the most important of which is simple landfill. If the amount of garbage decreases, then it can also be used to reduce the amount of arable land occupied by garbage.

1.3 4 of the composition of feces is water and 1 4 is solid; 30 of the solids are dead bacteria, 10 20 are fats, 2 3 are proteins, 10 20 are inorganic salts, and 30 are undigested food residues and solid components in digestive juices such as exfoliated epithelial cells. The yellow color of the stool is formed by the derivatives of bile red, dung bile pigment and urobiliary pigment.

The odor is caused by the products of bacterial action, mainly indole, skatin, mercaptan and sulfhydride. There are no less than 20 kinds of amino acids obtained by protein hydrolysis in feces, 2According to the above chemical composition, human feces are flammable, just like wolf dung used for wolf smoke.

3.Human feces contain various substances removed from the plasma by the kidneys in the urine, and the normal urine composition is (grams): sodium 3, potassium, magnesium, chloride, carbonate, phosphate 5, urea 18, creatinine, which indicates that the feces are quite corrosive, especially after fermentation, acid, ammonia, etc., ammonia salt, that is, ammonium compounds.

The main components of feces are protein and carbohydrate residues, and ammonia and water account for a large proportion.

Manure can be used mainly to make biogas, a city with a population of one million, excreting 200,000 tons of manure every day, can be used to make biogas, can basically solve the problem of civil fuel. That's a great asset!

If compressed in a cylinder, it can be used as fuel to drive a car.

The main components of human feces are cellulose and E. coli, please fill in the complete questions and I will answer them.

1. Human feces belong to kitchen waste, kitchen waste refers to the garbage generated in residents' daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, peels, eggshells, tea residues, bones, etc., which are mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

2. Feces, also commonly known as stool, is the relics of the large intestine of humans or animals. A quarter of the stool is water, and the rest is mostly proteins, inorganics, fats, undigested dietary fiber, dehydrated digestive juice residues, and cells shed from the intestines and dead bacteria, as well as vitamin K and vitamin B.

Human poop is wet garbage. Wet garbage, also known as kitchen waste and organic waste, is perishable garbage, which refers to perishable biomass domestic waste such as food waste, leftovers, expired food, melon peel and fruit pits, flowers and plants, and traditional Chinese medicine residues.

Feces, commonly known as "poop", "poop", "poop", etc., are relics of the large intestine of humans or animals. A quarter of the stool is the first part of the stool, and the rest is mostly protein, inorganics, fats, undigested dietary fiber, remnants of dehydrated digestive juices, and cells shed from the intestines and dead bacteria, as well as vitamin K and vitamin B. For farmers, manure can be used as an organic fertilizer for crops that are better to swim with.
