Changchun Outdoor Portable Toilet

The Changchun outdoor portable toilet is a modular sanitation facility designed for short-term crowd gathering scenarios, enabling rapid deployment and flexible application through its detachable structure and integrated functions.

I. Core Application Scenarios
It primarily serves short-term events such as sports competitions, cultural exhibitions, festivals, gatherings, and large-scale outdoor music festivals, as well as construction sites and temporary densely populated areas. Its core value lies in addressing the lack of flexibility in fixed public toilets, such as quickly providing sanitation services during unexpected public events or construction periods, avoiding service gaps caused by long infrastructure renovation cycles.

II. Technical Composition and Functional Modules

1. Excreta Collection Unit: Designed for sealed storage, it uses biodegradation or chemical agents for preliminary treatment to reduce odors and pollution risks. Some high-end models are equipped with vacuum suction systems to enhance excreta collection efficiency.
2. Water Supply and Flushing Module: It relies on independent water tanks or connects to external water sources, featuring water-saving flushing devices that control single-flush water usage to under 3 liters. Some enhanced-function toilets integrate recirculating water treatment systems for water reuse.
3. Structural Framework: Utilizing lightweight, high-strength composite materials (such as glass fiber reinforced plastic), each module weighs less than 200 kilograms, facilitating manual handling and mechanical lifting. Quick-connect interfaces between modules reduce assembly time to under 2 hours.
4. Auxiliary Systems: The ventilation system controls odors through forced air exhaust and negative pressure design; the lighting module uses LED sources and supports solar power; the signage system includes nighttime reflective signs and usage instructions to enhance safety.

III. Service Process and Rental Plans
The service process includes needs assessment (event duration, crowd size, site conditions), transportation and installation (handled by professional teams), usage and maintenance (daily cleaning, consumable replenishment), and retrieval and inspection (completed within 48 hours after the event). Rental plans are customized based on estimated crowd size and duration, with basic models meeting toilet and handwashing needs, and enhanced-function models offering additional features like barrier-free access, baby care stations, and air conditioning or heating systems, with rental fee differences of up to 30%-50%.

IV. Advantages and Limitations
Advantages include rapid deployment (completing the entire service process within 24 hours), spatial flexibility (movable to any flat ground), and environmental adaptability (supporting extreme temperatures from -30℃ to 40℃). Limitations include potential impacts on user experience during extreme weather conditions (such as strong winds or heavy rain) and the need for increased maintenance frequency with long-term, high-frequency use.
