Methods of Mobile Toilets

The classification methods of mobile toilets are mainly carried out from three perspectives: structural form, mobility method, and sewage treatment method, as detailed below:

From the perspective of structural form, mobile toilets can be divided into single-structure mobile toilets and composite-structure mobile toilets. Single-structure mobile toilets are usually designed simply, with the entire unit being an independent entity. They have the characteristics of small footprint and easy installation, making them suitable for places with limited space or high temporary demand, such as small outdoor event venues and construction sites. Composite-structure mobile toilets, on the other hand, are composed of multiple functional modules, with a more reasonable internal space layout. They can be equipped with various facilities, such as multiple toilet stalls, handwashing stations, and management rooms, meeting the usage needs of larger groups of people. They are commonly found at large-scale event sites and tourist attractions.

In terms of mobility method, mobile toilets include lifting and handling-type mobile toilets and powered and towed-type mobile toilets. Lifting and handling-type mobile toilets do not have the ability to move on their own and require lifting equipment such as cranes and forklifts for lifting and handling. Their advantages are relatively simple structure and low cost, suitable for places with low mobility frequency requirements and lifting conditions. Powered and towed-type mobile toilets are equipped with power devices or towing devices. Powered mobile toilets can move autonomously through their own power systems, offering high flexibility. Towed-type mobile toilets can be towed by vehicles, facilitating rapid transfer between different locations, suitable for scenarios requiring frequent movement, such as touring performances and mobile exhibitions.

Based on sewage treatment method, mobile toilets are divided into water-flush and non-water-flush suction-type mobile toilets and circulating water-flush mobile toilets. Water-flush and non-water-flush suction-type mobile toilets collect feces and other waste into a fecal storage tank through water flushing or suction, which is then regularly cleaned and transported for treatment. This treatment method is clean and hygienic but requires regular cleaning of the fecal storage tank, suitable for areas with a certain water supply and fecal transportation conditions. Circulating water-flush mobile toilets, on the other hand, adopt a circulating water system, using treated water for flushing to achieve water resource recycling. This reduces water consumption and waste discharge, making it more environmentally friendly and energy-efficient, suitable for areas with water scarcity or high environmental protection requirements.
