Introduction to Mobile Environmental Toilets

Mobile environmental toilets are public sanitation facilities designed based on new materials and water-saving technologies, featuring diverse technologies, flexible structures, wide applications, and environmental protection and water conservation.

Diverse Technology Types

Mobile environmental toilets encompass various technological approaches:

• Waterless Flush Type: No need to connect to water supply and drainage pipes. It uses biodegradable plastic bags to collect excreta, automatically replacing the bags and collecting them centrally after use, suitable for places without water sources or temporary locations.
• Foam Sealing Type: Utilizes foaming liquid to cover the surface of excreta, blocking odors and reducing the amount of flushing water, combining water conservation with hygiene.
• Water Flush Type: Requires connection to water supply and drainage pipes but achieves water conservation through technologies such as rainwater collection and filtration systems, and secondary use of hand-washing water for flushing. Some models are equipped with intermittent aerobic and anaerobic treatment devices, and the treated water can be recycled for flushing after adding biological bacteria.
• Dry Packaging Type: Without water flushing devices, excreta is collected by biodegradable plastic bags, which are automatically replaced and collected centrally after use, avoiding secondary pollution.
• Intelligent Water-Saving Type: By automatically collecting urine and hand-washing water and adding water-saving special agents, it achieves a flushing effect of about 0.46 liters of water per person, significantly reducing water consumption.

Flexible and Adaptable Structures

Their structural characteristics balance practicality and adaptability:

• Exterior Wall Materials: Options include color-coated steel plates, metal carved plates, anti-corrosion wood, stainless steel plates, and aluminum-plastic plates, meeting aesthetic and durability requirements for different scenarios.
• Main Structure: Adopts national standard light steel keel welding, meeting the requirements for overall hoisting, facilitating rapid deployment and relocation.
• Rich Configurations: Standard configurations include toilet bowls (urinals), coat hooks, vanity mirrors, paper baskets, lighting fixtures, exhaust fans, door locks, and occupancy indicator lights; optional configurations cover air conditioners (heating and cooling), air purifiers, anti-freezing systems, heating systems, background music, hand-washing basins, water-saving faucets, etc., which can be flexibly adjusted according to the usage scenario.
• Intelligent Control: Equipped with an intelligent control system and an insulation system, it achieves a low water flushing effect of 0.46 to 1.5 liters per person through upper and lower water tanks and water-saving special agents.

Wide Applications and Continuous Development

The application and development history of mobile environmental toilets reflect technological iterations and scenario expansions:

• Historical Evolution: During the third public toilet revolution (from the 1990s to the end of the 20th century), mobile public toilets evolved from wooden construction to the use of materials such as fiberglass and polyethylene; the fourth public toilet revolution (from the beginning of this century to the present) has spawned new products such as reclaimed water public toilets, sterilization and drying public toilets, solar public toilets, and waterless flush ecological public toilets.
• Form Expansion: Product forms include trailer-type, box-type substation cabinet-type, stainless steel kiosk-type, etc., adapting to the needs of public places such as scenic spots, service areas, and rural areas.
• Industrial Chain Perfection: Involving more than 20 production enterprises in Liaoning, Shanghai, Hebei, etc., forming a large-scale production and supply system.

Prominent Environmental Protection and Water-Saving Functions

Their core advantages lie in reducing resource consumption and environmental pollution:

• Waterless Flush Solution: No need to connect to water supply and drainage pipes, directly avoiding water waste, suitable for water-scarce areas or temporary events.
• Water Flush Solution Water-Saving Technology: Achieves efficient water recycling through rainwater collection, secondary use of hand-washing water, and biological bacteria recycling treatment.
• Low Water Volume Flushing: The intelligent water-saving type reduces the flushing volume per person to 0.46 liters through special agents and water recycling technology, far lower than traditional toilets.
