The excrement of the old carriage (car body) toilet is indeed discharged to the railway line, but with the upgrading of railway equipment and facilities, the toilet of the new carriage (car body) toilet has been greatly improved, and the function of collecting the toilet is adopted, that is, the excrement is received in the toilet, and when the train arrives at the end point, the staff will collect the excrement in the toilet with a special vehicle when the train is prepared, and send it to the designated place to make organic fertilizer!

Anonymous users2024-01-22The old cars of the past were lined up directly onto the railroad and fluttered in the wind. At present, the new carriages are all closed and recycled, and they are uniformly disposed of at the big station or the end point, and the railway pollution is gradually reduced.
I don't know how many trains pass by on the railroad tracks in a day, and the feces that fall from the strong wind do not know where the wind is blowing, and the rails are not ordinary steel, and they are very resistant to corrosion.
No, there are very few straight rows, and now they are all centralized processing, and then stop at the provincial capital railway station for more than ten to twenty minutes, this time is the ground staff to overhaul the train, add water, and absorb dirt! This suction is the disposal of manure.
The smell of the toilet contains sulfur dioxide, the odor emitted by urea, etc., which has an impact on people's sense of smell and respiratory system, and there are many bacteria on it. It can cause many diseases, and in the long run, it can be upsetting and irritable. >>>More
In the belly compartment of the aircraft, there are two large storage barrels of 260 liters, and the dirt in the toilets is flushed with disinfectant water or sent into the large barrels by vacuum suction for storage. After the plane arrives at the station, there is a special vehicle to pump out the excrement from the toilet and wash the storage bucket with clean water for use after takeoff. However, the small amount of waste water in the washbasin is discharged directly into the air, because the amount of water is very small, and it is absorbed by the atmosphere almost immediately and will never fall to people's heads.
The same septic tank sedimentation and purification treatment method as in China.
