Suqian Simple Mobile Toilet Design
The design of the simple mobile toilet in Suqian revolves around temporary sanitation units, modular structures, and environmental adaptation systems, while also emphasizing usage requirements to meet temporary sanitation needs.
Temporary Sanitation Units: As the core functional component, they primarily safely accommodate and initially treat human waste. Internally equipped with sewage storage tanks made of specific polymer materials, these tanks offer excellent sealing and durability. Additionally, they are paired with chemical or biological degradants that accelerate waste decomposition through the action of enzymes or microorganisms, or utilize chemical agents to inhibit the emission of gases such as ammonia and hydrogen sulfide, effectively reducing odors and pathogen proliferation. In design, it is necessary to balance the capacity of the sewage storage tanks, sealing, and the convenience of later cleaning and transportation, ensuring that they can meet a certain usage duration while facilitating subsequent cleaning and transport.
Modular Structures: Composed of lightweight metal frames and composite panels. The lightweight metal frames feature standard interface designs, allowing for flat-packed loading during transportation to save space; upon arrival at the site, they can be quickly assembled into shape through a limited number of steps, achieving a balance between rapid assembly/disassembly and stability. The composite panels must possess thermal insulation, flame retardancy, and privacy shielding properties, providing users with a safe, comfortable, and private space. The advantage of modularity lies in the ability to horizontally拼接 multiple units according to the number of users and site conditions, forming a large-scale temporary sanitation facility cluster that flexibly adapts to different scenarios.
Environmental Adaptation Systems: Include ventilation and air exchange devices that achieve directional airflow through passive air ducts or small active exhaust fans, maintaining slightly lower internal pressure than the external environment to effectively control odor overflow. In sites lacking municipal water supply and drainage, the system also encompasses water-saving flushing devices or dry treatment designs, as well as independent lighting power supplies, ensuring that the facilities can operate independently for a short period when disconnected from the urban infrastructure network.
Usage Requirements: Emphasize the separate collection of feces and urine, with toilet paper placed in baskets and burned when full, adding ash after defecation, covering pit positions with lids on a daily basis, and urinating in designated areas to improve space utilization and allow for mixed use by men and women. For outdoor public toilets, urine separation and the installation of partitions in urinals along with the placement of gravel, combined tightly with fecal storage pits, allow diluted urine to be used for crop fertilization after storage.
