[0001] The invention relates to the technical field of waste treatment in train toilets, and in particular to a system and method for degradation treatment of waste in train toilets. Background Art

[0002] With the continuous development of modern train transportation, more and more high-speed trains and long-distance trains are put into use, and the problem of waste treatment in train toilets has become an important issue that cannot be ignored. The treatment of waste in train toilets not only involves the cleanliness of the carriages and the sanitary environment of passengers, but is also closely related to environmental protection requirements, resource utilization and the efficiency of train operations. Therefore, the development of an efficient, safe and environmentally friendly waste degradation treatment system has become the key to the development of train toilet technology.

[0003] The existing toilet products for vehicles require fixed-point treatment of vacuum toilet boxes in plateau environments, which is not conducive to long-term use during vehicle operation and increases emission costs. In some trains, waste is directly discharged under the track through pipes. However, this treatment method seriously pollutes the environment, especially in cities or densely populated areas. The discharged waste may pollute the ground environment and even affect public health.

[0004] Therefore, the present application provides a system and method for degrading and treating waste in train toilets to meet the needs. Summary of the invention
