Degradation-type Mobile Toilet

A degradation-type mobile toilet is a type of public toilet that utilizes microbial decomposition technology to achieve harmless treatment of excreta, featuring water conservation, mobility, and no water flushing.

Technical Characteristics

1. Structural Composition: It includes a squatting pan, fermentation and degradation tank, exhaust pipe, forced ventilation device, heating device (approximately 800W), and mechanical transmission device, achieving automated operation through a PLC constant temperature and humidity control system. The fermentation and degradation tank is the core component, responsible for holding excreta and microbial inoculum carriers, and promoting decomposition reactions through mechanical stirring.
2. Operation Method: After mixing excreta with microbial inoculum carriers, mechanical intermittent forward and reverse transmission stirring is applied, decomposing the mixture into carbon dioxide, water, and organic fertilizer under the action of microorganisms. The compliant gas is discharged through the exhaust pipe. Some models are equipped with an intelligent temperature control system, operating at temperatures above 60℃ to enhance sterilization and disinfection effects. The daily power consumption is approximately 3 to 5 degrees (depending on the number of users).
3. Maintenance Cost: The replacement cycle for inoculum is 3 to 6 months, with costs varying by inoculum type: domestic inoculum costs about 300 yuan per toilet unit, while imported inoculum costs about 500 yuan per toilet unit. The annual maintenance cost is approximately 15,000 yuan, including inoculum replacement, equipment maintenance, and cleaning.

Application Scenarios

1. Environmental Adaptability: The steel frame structure supports use in environments ranging from -28℃ to 50℃, making it suitable for scenic spots, high-altitude and water-scarce areas, and public places. In 2022, this technology was deployed in 13 venues for the Beijing Winter Olympics, with the construction cost per toilet unit being 100,000 yuan lower than that of traditional water toilets; the carbon-neutral public toilets deployed in Chengdu in 2024 saved over 3,000 tons of water annually.
2. Environmental Benefits: It requires no water flushing, no transportation for waste removal, and produces no pollution, complying with the national 863 Program's standards for 'special microbial resource development and utilization technology' and passing the Shanghai Microbial Inoculum Safety Certification. The decomposition products can be recycled as organic fertilizer, reducing resource waste.

Product Types and Prices

1. Materials and Prices: Materials include color steel plates, carved panels, and aluminum-plastic panels, with prices ranging from 800 yuan per square meter (basic type) to 6,000 yuan per unit (high-end type). High-end models are usually equipped with more advanced temperature control systems and durable materials, suitable for long-term high-frequency use scenarios.
2. Customization and Supply: Some products support custom processing, with a supply cycle of within 30 days, allowing adjustments to size, functional modules, and exterior design according to site requirements.
