The grey water collection and treatment device for high-speed train toilets is a set of equipment systems specifically used to collect, store, and treat grey water generated in high-speed train toilets. This device aims to effectively manage grey water, reduce environmental pollution, and ensure hygiene, safety, and environmental protection requirements during train operation.

[0003] The traditional greywater collection and treatment device in high-speed train toilets has a relatively complex filtration structure, making it inconvenient to clean and maintain the filtration system. Secondly, the disinfection process of the traditional greywater collection and treatment device in high-speed train toilets is relatively simple, which can easily breed bacteria and odors, affecting the hygiene environment inside the carriage.

[0004] Therefore, those skilled in the art have provided a grey water collection and treatment device for high-speed train toilets to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a greywater collection and treatment device for high-speed train toilets. Greywater is introduced through an inlet, a filter frame filters out larger impurities, a filter plate filters out smaller impurities, and an activated carbon layer adsorbs fine pollutants and removes odors from the greywater. The activated carbon layer can be pulled out and replaced separately to ensure its deodorizing effect. When the filter bucket is inserted into the housing, a pressure limiting block pushes a spring backward, and the spring pushes the limiting block tightly against a rubber pad to prevent leakage. The entire device can be removed for cleaning to prevent internal contamination and ensure effective greywater filtration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A greywater collection and treatment device for a high-speed train toilet includes a housing. A filtration mechanism is installed on one inner wall of the housing. The filtration mechanism includes a filter bucket slidably connected to the inner wall of the housing. A filter frame is slidably connected to the upper end of the inner wall of the filter bucket. Support frames are fixedly connected to both sides of the middle section of the inner wall of the filter bucket. A filter plate is slidably connected to the upper surface of the support frames. A through groove is formed in the middle of the front end of the filter bucket. A waterproof gasket is fixedly connected to the inner wall of the through groove. An activated carbon layer is slidably connected to the inner wall of the waterproof gasket. The activated carbon layer has two ends on its outer front wall.
