How is defecation handled in an airplane toilet?

The sewage equipment on the aircraft consists of a bedpan, a sewage tank, a filter, an electric pump, a sewage canister, an inflatable pipe, and an exhaust pipe. After the defecation is defecated, the electric pump works, and the water in the sewage tank passes through the filter, the electric pump reaches the bedpan and washes the feces down. After the feces enter the sewage tank, the water can be recycled again after chemical sterilization, deodorization, dyeing and separation.

At the end of each flight, these items are taken to the ground for handling, rinsing and changing.

There is not only one toilet on the plane, but also toilet paper, disinfectant wipes, soap, perfume and other items in the toilet, which is both hygienic and convenient.

On Earth, everything has its own physiological needs, and we humans are no exception. Most animals don't have anything to pay special attention to when it comes to solving their physiological needs, and they can basically be solved nearby. But we humans are a civilized species and pay more attention to privacy issues, so we need to do it in a specific place, which is what we commonly call "toilets".

If we are at home or at work, we can find a toilet nearby, and it is easy to find a public toilet nearby on the road. But how to solve it on a high-altitude vehicle such as an airplane? In fact, there are public toilets in these places, but it is impossible to dispose of excrement by connecting to sewers on high-speed vehicles such as airplanes like toilets on land, so how to deal with them?

In the earliest days, airplanes had a history of "direct excrement", because the storage space on the airplane was very valuable, so the airplane directly discharged the excrement from the body. However, due to safety and hygiene concerns, this treatment was not followed.

For today's aircraft, the purser points out that the aircraft has two wastewater systems. If it is water used for hand washing, the plane will still drain it directly.

Because the airplanes fly at a high altitude, when the water is discharged, it will decompose in the air due to the action of the air current, and it will not cause any effect.

The other is what to do with human waste, after the waste enters the toilet, the high-pressure air flow generated by the vacuum sends it to a special storage box in the belly of the aircraft, where a special blue chemical with deodorizing and decomposing effects is added for treatment. After the plane lands, a special person will take care of the storage box and dispose of it.

Here I have to sigh that human science and technology are really getting stronger and stronger, and once there is a problem, it can be solved through technology. It is believed that in the near future, people's science and technology will become more and more developed.

For short-haul routes, it is generally carried directly to the airport to land, after all, you don't need to carry a lot of poop for short-haul flights. If it is a long distance, some of it will be thrown directly into the Pacific Ocean, forests, etc.

There have been news stories before that foreign countries found the wreckage of the plane at sea, and the result was thrown down garbage. But when the plane flies in the stratosphere, the garbage thrown down is disposed of and thrown directly, and the free fall will definitely decompose in the air, and even if a small amount falls to the ground, it will be decomposed by microorganisms (which is also the reason why it is thrown on the forest, and nothing will go to other people's heads).

However, this is not very hygienic, and most of the modern large planes will be carried to the ground for disposal. In the standard toilet of large civil aircraft, after the passenger is "convenient", a small amount of clean water will flow out of the toilet wall when the button is pressed, and some septic agents will be added, and the vacuum device will suck your "excrement" into it, and all the urine and urine will be sucked into the waste container of the aircraft. There are filters on the waste containers that filter out the "bulky" and the filtered water flows back to the restroom to wait for the next flush.

At the same time, the huge vacuum suction sucks the feces into the two-layer "manure tank" carried by the aircraft, and after reaching the ground, the feces will be stored and processed by a special fecal storage vehicle. This protects the environment to a great extent and is very convenient.

Some of the liquids, such as some liquids, are directly connected to the outside world, and the discharged items from the toilet move vertically in the troposphere, which can be dismantled instantaneously, so there is no need to worry about falling down.

But this sewage outlet sometimes malfunctions, and the discharge is excessive, and the result is that there are news reports that someone picked up the blue ice falling from the sky, and that thing is actually the excrement leaked from the plane, but it is the sewage bin of the aircraft that is faulty.

Most of the solid ones are stored by professional sewage equipment

In the standard toilet of large civil aircraft, after the convenience of passengers, press the button, a small amount of clean water will flow out of the toilet wall, and some also add septic agent to dilute and flush the effect, and at the same time, the huge vacuum suction will suck the feces into the two-layer structure of the fecal tank carried by the aircraft, and after reaching the ground, the feces will be stored and processed by the special fecal storage vehicle.

There is a dirt container in the aircraft bathroom, the fuselage is closed, it is impossible to excrete into the air, so it is not stinky, and after the plane lands, it is pumped out by a special vehicle to empty and fly again, and the dirt is treated on the ground!

Of course, you don't have to worry about it, because when the plane is flying at high altitude and high speed, the feces will be directly dispersed by the air in the air, and it will not fall down at all, and the urine will be vaporized directly into the atmosphere!

There is a water tank on the plane with clean water, and there is also a sewage tank, which goes into the toilet bowl and pumps the urine and urine into the sewage tank for storage through the internal pressure difference of the plane in the sky, and the special sewage truck takes the sewage away after the plane lands.

Aircraft toilets now use today's vacuum toilet drain systems for safety and environmental reasons. The excrement inside the aircraft toilet bowl is sent by the high-pressure air flow generated by the vacuum to the storage box in the belly of the aircraft, where it is treated by the addition of blue chemicals that have a deodorizing and decomposing effect. The opening and closing valves of the storage box are located on the outside of the fuselage, ensuring that the excrement can only be transferred to the disposal vehicle by the ground crew** after the aircraft has landed.

It is stored in the storage box in the belly of the aircraft with vacuum compression technology, and the odor treatment is carried out with deodorant, and the storage box switch is only on the outside of the aircraft, so as to ensure that only after the aircraft lands, it will be packaged and processed by the ground staff into the first car.

Hello, there are three places on the plane to drain water, one is kitchen water, one is toilet handwashing water, and toilet water. The first two are discharged to the outside of the machine through two antifreeze heating pipes, and the latter is slapped into the sewage tank

It is broken down by air currents, the speed of the aircraft and the velocity of the air above the clouds, which breaks down the urine and urine into fine particles.

Airflow breakdown. The speed of the plane, combined with the velocity of the air above the clouds, breaks down the urine and urine into fine particles.

What is done with the feces on the plane?

Toilet feces on the plane are sent to a storage box in the belly of the plane by a high-pressure air stream generated by a vacuum, where it is treated by adding a blue chemical that has a deodorizing and decomposing effect. The opening and closing valve of the storage tank is located on the outside of the fuselage, which ensures that the excrement can only be "thrown" in mid-air by the ground crew** after the aircraft has landed.

In addition, wastewater from washing hands in aircraft lavatories and rainwater collected at boarding gates and other places is called grey water, and it can be discharged through the drain of the fuselage at high altitudes. Due to the high altitude, the unpolluted water will be broken down by the air currents without any effect.

1. There are two treatment methods: the first is to discharge directly into the air.

2. The second is to gather together through the toilet and put it in the designated location after arriving at the destination.

3. The excrement on the aircraft is first discharged into the air. At first, the plane emitted only excrement from the air, but did not take into account the chemical reactions in the atmosphere. These feces contain so many elements that not everything can be completely broken down as it passes through the atmosphere.

4. As a result, a lot of feces fall to the ground without completely decomposing, causing trouble to people. But science and technology always need to be improved. Now a small thing is installed on the plane, the toilet, which can avoid unnecessary troubles before.

5. A toilet with feces was installed in the toilet of the aircraft. When the plane lands, the flight attendant will dispose of the excrement inside. A high-tech filter is also installed inside the box to ensure that there is no contamination for the next use.

So every time the plane lands, the small box of feces inside is cleaned up and does not cause any trouble to people.
