Biodegradable Mobile Toilet

A biodegradable mobile toilet is an environmentally friendly sanitation facility based on microbial decomposition technology, suitable for areas without water supply and sewerage networks. It decomposes excreta through microorganisms and converts it into organic fertilizer.

Core Technology and Functions

The core technology of a biodegradable mobile toilet is microbial decomposition. The device consists of a squatting pan, fermentation and decomposition tank, exhaust pipe, exhaust fan, mechanical transmission device, and an electrical PLC constant temperature and humidity control device. The fermentation tank is equipped with microbial strains and a mixer, achieving mixed decomposition of excreta through constant temperature heating (approximately 800W) and mechanical transmission. Microbial strains can decompose excreta into carbon dioxide, water, and a small amount of organic residue. The treated gas is discharged in compliance with standards, and the residue is converted into organic fertilizer, achieving resource utilization.

Operational Characteristics and Energy Consumption

The device adopts a waterless flushing design, triggering the opening and closing of a movable baffle through photoelectric induction to reduce water consumption. Its mixing structure is a spiral double-auger, ensuring thorough mixing of excreta and microbial strains. Daily power consumption is 3-5 kWh (depending on usage frequency and regional differences), with a voltage of 220V and an applicable temperature range of -30℃ to 50℃, demonstrating strong adaptability. Microbial strains need to be replaced regularly, with domestic strains costing approximately 300 yuan per toilet unit and imported strains about 500 yuan per unit, with a replacement cycle of 3-6 months.

Materials and Application Scenarios

The outer shell of the device is made of various materials, including color-coated steel plates, carved panels, and aluminum-plastic panels, balancing durability and aesthetics. Its standardized production has been applied in public areas such as Beijing Olympic venues and the Badaling Great Wall, suitable for scenarios without water supply and sewerage networks, such as tourist attractions, construction sites, and temporary events. Additionally, some products integrate a spiral double-auger mixing structure to enhance decomposition efficiency and are equipped with exhaust fans and exhaust pipes to ensure gas emissions meet standards.

Market Brands and Prices

Mainstream brands in the market include Youxuan, Kangyuan, Jiayong Sanitation, Baitai, Miaoxin, Futaixiang, Muda, Shengfengshang, Sailina, and Lintian Environmental Protection. Prices vary significantly depending on brand, specifications, and region. For example, products from Hebei Cangzhou Pulin Steel Structure Co., Ltd. are priced at 1800-4500 yuan per unit, those from Hebei Langfang Dezhou Muda Machinery Equipment Co., Ltd. are 3000 yuan per set, and those from Sichuan Chengdu Sichuan Gerunsi Environmental Protection Equipment Co., Ltd. are 6000 yuan per unit. Users can choose appropriate models based on their needs, balancing cost and performance.
