How is the waste from the toilet on the plane disposed of?

Specifically, when the passenger "skimmes" and presses the flush button, a small amount of water will flow out of the toilet wall, and some will also add septic agents that play a role in dilution and flushing, and the valve at the bottom of the sink will be opened, and the huge vacuum suction will suck the feces into the special "fecal tank" at the rear of the aircraft. Excrement will remain in it throughout the flight until the plane lands, when ground staff will be responsible for cleaning it up. Since the excrement in the airplane toilet is specially concentrated, what about the "excrement blue ice falling incident" mentioned in TV shows such as "Mythbuster" and "Approaching Science"? >>>More

The belly of the aircraft is equipped with a large storage tank, like a large wet and dry vacuum cleaner, the vacuum cleaner system sucks the contents of the toilet into the chemical storage tank in the belly, and at the same time injects the filtered chemicals into the bedpan to flush the excrement, and the non-stick material similar to PTFE on the inner wall of the toilet ensures that the dirt can be easily flushed out. >>>More

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. >>>More

The toilets above the plane and below are places where feces are collected. >>>More
