The toilet on the plane discharges the excrement directly into the sky?

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. But many people don't know where all the products of our "Izuku" on the plane have gone. Many people think that it is like a train to just open a small hole and line it outside.

Ouch, it feels disgusting to think about. After a child took a plane, he said to his mother, "I will never open my mouth again when I go to the street."

There are also people who have made such a "scientific explanation": the distance of the plane from the ground is 10,000 meters, and those "things" have long been weathered when they are in free fall.

This is actually a very unhygienic assumption. In fact, 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.

I am a staff member of China Southern Airlines, let me answer your question, most of the current passenger planes dump excrement directly into the air, because the high temperature generated during the falling process can decompose the excrement, and only a few types of passenger planes will be disposed of and then discharged.

Some of the airplane toilets are directly connected to the outside world, and the discharged items of the toilet move vertically in the troposphere, which can be dismantled instantly, so there is no need to worry about falling.

In the standard toilet of large civil aircraft, after the passenger is "convenient", after pressing the button, a small amount of water will flow out of the toilet wall, and some also add septic agent to play the role of dilution and scouring, 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.

How can it be? If this is the case, how many planes fly in the sky every day, and can there still be people living below?

Those things are stored temporarily and then dismantled by special treatment.

It must be temporarily stored, and then handed over to the ground for unified processing after it arrives on the ground.

It can't be just scattered in the air.

Dizzy! You can really figure it out!

You think it's the same as a train!

They have a fixed device for depositing.

It is impossible to rank in the sky.

Of course not, it has to be decomposed after special treatment and then turned into gas emissions.

Otherwise, we don't have to go out with umbrellas every day.

That bubble doesn't fall on your head, haha!!
