What do you do after the guests on the plane and train urinate?

Because the toilets of most trains in China are directly connected with the outside world, the pollutants discharged by passengers are directly discharged on the rails. If the train is close to the city, these pollutants will pollute the surrounding environment, so the toilet must be closed when the train enters the city. When the train runs at high speed, the discharged pollutants will collapse instantly and will not cause too much pollution to the environment along the railway. It will also decompose quickly. However, the closure of the train toilets has also brought the same troubles to the passengers. During the time when the train entered and left the city, the passenger's toilet became a problem. Therefore, the toilet collection device has been adopted on the new 25T train in China, and the toilet sewage is no longer directly discharged on the rails, but collected in the toilet collection device, which will be treated after the train enters the garage. This not only protects the environment, but also greatly facilitates passengers.

The blowdown equipment on the plane consists of bedpan, sewage tank, filter, electric pump, blowdown cylinder, gas filling pipe and exhaust pipe. After defecation, the electric pump works, the water in the sewage tank reaches the bedpan through the filter and the electric pump, and the feces are washed down. After the feces enter the sewage pool, the water can be recycled after chemical sterilization, deodorization, dyeing and separation. After each flight, these things should be taken to the ground for treatment, cleaning and replacement of liquid medicine.
