Zhongguancun Mobile Toilet
The mobile toilets in Zhongguancun are characterized by convenient use, complete facilities, a strong sense of technology, as well as resource recycling and energy self-sufficiency.
In terms of convenience: The upgraded mobile toilets on the streets of Zhongguancun do not require external water and electricity connections. This design greatly enhances their layout flexibility, free from the constraints of traditional water and electricity lines. Users can simply scan the QR code at the door with their mobile phones to easily start using them. The operation is simple and easy to understand, facilitating people of different age groups.
Regarding facility equipment: The interior of the toilet is spacious, providing a comfortable toilet environment. At the same time, facilities such as free toilet paper, mobile phone holders, air fresheners, and mirrors are all available. Free toilet paper meets the basic needs of users; mobile phone holders make it convenient for users to place their mobile phones while using the toilet, preventing them from falling; air fresheners can improve the odor in the toilet and enhance the user experience; mirrors are convenient for users to tidy up their appearance.
In terms of technological features: The QR code at the door is not only used to open the toilet but also supports self-service purchasing of goods, providing users with more convenience. In addition, through the Huajie Toilet Guidance Mini Program, users can obtain the location information of other nearby toilets, which is very practical for users looking for toilets in a large area.
Regarding resource recycling and energy self-sufficiency: Some mobile toilets adopt an advanced micro-system. In terms of excrement treatment, a solid-liquid separation device is used to separate the liquid from the solid. The liquid is treated by a multi-layer biofilm reactor and can be reused for flushing the toilet within 3 to 5 hours after the water quality meets the standard; the solid is converted into dry particles through low-temperature pyrolysis, significantly reducing its volume. In terms of energy conversion, the flexible photovoltaic film laid on the top can convert solar energy into electricity and supply it to the equipment itself preferentially; if the electricity is insufficient,沼气 (biogas) fermentation power generation is carried out using the solid particles, and the generated electricity is charged into the equipment's battery. In terms of odor control, a two-stage treatment is adopted. The liquid-sealed valve below the toilet can isolate odors, and the photocatalytic oxidation module in the exhaust duct has an removal efficiency of about 95%, effectively improving the air quality inside the toilet.
