How to solve the problem of excretion in the space capsule?

Astronauts solve the problem of urinating through a "funnel". The "funnel" is connected to the hose, and the other end of the hose is connected to the urine collection system. When the astronaut urinates, the fan in the collection system is turned on so that urine can be sucked from the funnel through the hose into the urine collector.

Use a dedicated "flush toilet" for stool. It is sucked by a fan, first to remove the moisture and odor in it, and then seal the dry part with a plastic bag. Due to the lack of gravity in space, astronauts' intestines are in a floating state, and internal organs cannot work normally, so astronauts often have problems such as difficult bowel movements and long time consuming.

Privacy

Unlike rooms on the ground, room meetings in the capsule are set up on the ceiling and walls. Each room has a door, which can protect their privacy to the greatest extent, and the items in the room are brought by astronauts from the earth, so the privacy of the room is still relatively good.

There's a special toilet in the capsule, and it's suction, and it's aligning the excretory organs with it, creating a sealed space, so that the excrement can be sucked into a specific space.

There is the exclusive toilet of the space and is designed by weightlessness in space.

This depends on the length of time, if it is only one or twenty hours of space travel, it will be much simpler, before going up, soup will be poured to clear the intestines, so as to avoid the appearance of stool in a short period of time, for urine, this can be worn diapers to solve, this is only suitable for short-term travel, Yang Liwei went to space is basically like this.

Now the technology is much more advanced, and it will not go back quickly in space, and it will generally stay in space for a period of time, so it is necessary to solve the problem of excretion in space, after all, in the weightless environment of space, many things are completely different from those on the ground, and they cannot be carried out according to the earth, so some special improvements will be made specifically for space excretion treatment.

In fact, the excretion in space is carried out by negative pressure pumping, that is to say, if there is no negative pressure equipment to deal with it, the result will be the diffusion of odor and the excrement floating in the air, imagine what the scene is, so through special equipment, the excrement is pumped into a special treatment container through negative pressure pumping, and then the next step of treatment.

The way to dispose of feces is to pump it into a reservoir for disinfection and sterilization, and then after a series of practices, store the excrement and pack it back to the earth for processing, and it cannot be discarded in space, so it is generally placed in one place, and when it returns, it enters the atmosphere, and when it is rubbed and burned with the atmosphere, the container of these excrements will be burned together, and by the way, the excrement inside will also be burned together.

The treatment of urine is different from stool, the stool will be packed and brought back for processing, and the urine will be collected and fermented, and then distilled to become pure water** for use, and the unusable part will be put into a container with the stool, and when the time comes to return to the earth, it will be incinerated in the atmosphere and will not be left in space.

The main thing is that the current excrement appliances are separated, and all of them have been specially transformed, which are completely used in response to the weightless environment of space, which contain a combination of modern science and technology, which looks simple but is actually a very complex thing, these are actually not embarrassing, for space science exploration, all aspects of human physiology must be considered to solve, so these do not need us to worry, scientists have already had a way to solve them.

Scientists have developed a special bag that is installed inside the astronaut's clothes and can directly collect the astronaut's excrement.

Now the treatment method is very advanced, the spacecraft has a toilet inside, and the equipment is particularly complete, which can separate the dry and wet excrement and reuse it to make pollution-free drinking water.

Astronauts wear diapers during space exploration, and there are special equipment for handling excrement when they are in space.

They have professional toilets, which are designed to deal with the environment in space, and can easily deal with this problem.

The physiological needs of astronauts in space are generally eating, sleeping, going to the toilet, etc., the liquid food eaten by astronauts is generally packed in a hose similar to toothpaste, and the solid food is sent directly to the mouth when eating, and the solid food is sent to the mouth with a fork or chopsticks, and you need to tie yourself in a sleeping bag when sleeping, and you generally use a wet towel to wipe it when you take a bath. If you want to know more about "how astronauts solve their physiological needs in space", you can read on.

1. Objects and people are in a state of weightlessness in space, they are all floating, and astronauts carry out daily activities such as sleeping, eating, and bathing on them are not exactly the same as on Earth.

2. In space, if an astronaut wants to sleep peacefully, then he needs to bind himself to a sleeping bag. Water does not flow down in space, so astronauts usually use cups with straws to drink water.

3. If you are a female astronaut, you will generally delay menstruation through medications, such as birth control pills. Water in space is very precious, and astronauts' urine is sterilized, filtered and reused.

4. Because space is weightless, water will not flow down, astronauts can not take a bath and wash their hair on it like on the earth, they generally use no-rinse shampoo and wipe their bodies with towels.

<> the urine and other water in space can be reused after special treatment, and the waste that cannot be purified is generally transported back to the earth with other garbage.

The space station is a large enclosed space where the feces produced by astronauts living on the space station must be collected and disposed of.

Take, for example, astronauts' urine, sweat, and other excrement. These are actually water**, which contains 96% water in the urine alone. This wastewater from the human body can be purified after multiple layers of purification, and other substances other than water will be collected and packaged.

The water can be used to electrolyze to make oxygen or for astronauts to drink. While drinking water purified by one's own urine is disgusting and may be unacceptable to most people, the purity of the water purified by the station's water treatment system is higher than the pure reed wax water available on the market. According to reports, the urine treatment system of the Chinese space station can extract 5 liters of purified water from 6 liters of urine in two hours.

As for astronaut feces, it is basically food scraps and has no ** value at the moment. If you want to immigrate to Mars to grow vegetables, it will have practical value. After the manure is collected, it is dehydrated and dried, and then compressed and packed in a sealed bag to save storage space.

The water obtained from the feces will also enter the ranks of **.

These inaccessible substances, including feces and household waste, used to be thrown directly out of the space station, but because they were not fast enough, they would become space trash moving around low Earth orbit. Space garbage moves very fast and can move at high speeds of several kilometers per second. Even a small mass poses a serious safety risk to the spacecraft.

Since the scientists realized the dangers of space waste, the waste of feces and other garbage that can no longer be used will be packaged and brought back to Earth. Cargo ships are now disposable. After transporting materials to the space station, they also take away the garbage on the space station.

The ship burns on the way back to the atmosphere, and the garbage naturally burns. Even if it doesn't burn completely, most of the time it falls into the ocean.

They will pump the feces into the reservoir, and then disinfect and sterilize them, and after a series of operations, Harutaka will store the excrement and bring it back to Earth for processing, they will not throw some land-grabbing garbage into space, and when they return, they will enter the atmosphere and burn the atmosphere against the atmosphere, and they will burn the containers of these excrements together.

There is a control lever under the handle, twisting the lever to adjust the air flow of the nozzle, the toilet lid is automatically closed, the Lixiao front surface forms a vacuum, the feces are quickly dried, and the solid part is regularly thrown out of the cabin, allowing it to enter the atmosphere and burn up.

I think there are special space toilets in space, and there is a very peculiar air flow in the space toilet, and the moment you open the lid, you will move the group stool, which will also absorb all the excrement into the interior for work, and there is a very strong filter inside, which will remove all the unclean objects and refine the travel quality to achieve the process of recycling.

Astronauts in space settle urination in collection bags.

On Earth, whether you're using a hole in the ground or a gorgeous gilded toilet, your excrement will naturally pull down and away from you due to gravity. But for astronaut Maxin, this kind of "due diligence" is a bit complicated.

In the absence of gravity, any loose droplets of water can float out of the toilet. This is not only detrimental to the health of the astronauts, but also adversely affects the sensitive equipment on the space station.

More than 90% of the urine after using the toilet is water. Because water is heavy and takes up a lot of space, urine is easier and faster than bringing clean water from the earth. As a result, all astronauts' urine is collected and converted into clean drinking water.

Sometimes, astronaut feces are brought back to Earth for scientists to study, but most of the time, toilet waste, including feces, is incinerated. Typically, the manure is vacuum-sucked into garbage bags, which are placed in sealed containers.

Astronauts also drop used toilet paper, wipes and cleaning gloves in the container. The containers are then loaded onto a cargo ship carrying supplies to the space station, which is launched from Earth and will also burn up in the Earth's upper atmosphere.

Selection of astronauts

Aerospace activities are a special kind of professional activities, which have the characteristics of special working environment, highly complex vocational skills, and arduous flight tasks.

Such a profession requires astronauts not only to have a healthy physique and good mental quality, but also to have a high degree of tolerance and stress resistance to the space environment, and at the same time should have profound knowledge and superb skills. Therefore, all space departments in the world have carefully selected astronauts.

It is the same as the pilot selection, but the level of education and work ability are more demanding. The selection of mental quality is an important aspect of the selection of astronauts, and it is necessary to find out the personality, emotional stability, mental state, adaptability and coordination of working with others.

In the early days of manned spaceflight, people attached great importance to the selection of endurance in special environments, but with the continuous development of aerospace technology and the gradual improvement of the environment in manned spacecraft, some special environmental factor tests, such as noise, vibration, and temperature, were no longer the main content of the selection.

The special environment endurance selection is mainly carried out to test the ability to adapt to weightlessness and re-adaptation after returning, such as vestibular function test, overweight endurance test, low-pressure hypoxia endurance test, etc.

Astronauts urinate in the dust space through a funnel and through a hose into the urine collector, while the big Mengbi Zen uses a special toilet bowl.

Astronauts urinating and defecating in the microgravity environment of space is actually a more troublesome and complicated thing, the internal organs of astronauts are in a floating state, cannot work normally, and it is difficult to defecate, and the toilet is vacuum.

If astronauts need to defecate in space, they need to use a special exhaust toilet, which relies on a fan to suck out the water and odor, and then seal the dry part with a plastic bag, and then these plastic boxes containing feces will be bounced into space. When it is convenient for astronauts, they need to fix themselves first, put their feet in fixed shoe covers, tie their waists with seat straps, and hold the handles with their hands.

Space diet for astronauts

1. Ready-to-eat food: it is something that can be eaten immediately and does not need to be reprocessed, such as dry food with medium moisture, bite-sized compression molding or treated with a smart ruler coating film.

2. Rehydrated food: This kind of food is freeze-dried food, because it is light and small when it is sent to space, and it occupies a large proportion in aerospace food, but it must be rehydrated before eating, and there is a one-way water inlet valve on its packaging bag, so that it can be used for rehydration, and it can be eaten after rehydration.

3. Heat-stabilized food: This kind of food is a soft and hard packaged canned food that has been heated and sterilized by self-care, commonly known as "soft and hard canned food". They are characterized by not only containing a normal amount of water, but also being the closest to ordinary food from the mouth to the shape.

Space flights proved that it is perfectly feasible to take food from an open container with ordinary cutlery in weightlessness. Such instruments also account for a large proportion of aerospace instruments. For example, in the Soviet Salyut-6 space station, this instrument accounted for about 80.

Put it in a special collection bag and return to Earth with you for fertilizing ......Ensure that the crops grow and ......Whoever calls people is a foreign fertilizer......Hehe, just kidding, you can't stay in space, you have to bring it back to the ground, you can't litter in space, or maybe there will be news about ...... in the futureAn astronaut was hit by excrement left in space at an unknown time and died heroically ......
