Types of Mobile Toilets in Sichuan

There are various types of mobile toilets in Sichuan, which can be classified according to their functions, treatment methods, and usage scenarios as follows:

I. Classification by Function and Treatment Method

1. Foam-Sealed Type
   It generates foam through a foaming device to cover excrement, eliminating the need for flushing. The lubricating and sealing effects of the foam reduce odor diffusion. Its advantages lie in water conservation and environmental protection, making it suitable for places with high environmental requirements such as scenic spots and parks, with relatively low maintenance costs in the later stage.

2. Mechanical Packaging Type
   It adopts automatic packaging technology, where excrement is sealed with a film and then processed collectively, without any manual contact throughout the process. It is characterized by easy operation and no pollution, suitable for temporary scenarios such as construction sites and picnics, but requires regular replacement of packaging bags.

3. Water-Flush Direct-Discharge Type
   It relies on high-pressure water flushing for cleaning, with excrement directly discharged into the municipal sewer network. It has strong flushing power and high cleanliness, commonly found in commercial area renovations or areas with sewage discharge conditions, but has relatively high requirements for infrastructure.

4. Simple Single-Squat Type
   Its basic configuration only includes a single squat position, with a low price (about 2500 yuan). It meets the needs of temporary activities, such as exhibitions and fairs, but has a single function and relatively poor comfort.

II. Classification by Configuration Level

1. Basic Model
   It is equipped with a squat toilet or a sit toilet, along with a simple flushing system. It is suitable for scenarios with limited budgets or short-term use, such as rural public areas or temporary construction sites.

2. Advanced Model
   On the basis of basic functions, it adds a sink, a mirror, and a shelf. Some high-end models are also equipped with heating and drying equipment (suitable for winter), a ventilation system, and an emergency call button. It is suitable for places with high requirements for user experience, such as scenic spots and service areas.

III. Classification by Drainage Method

1. Direct-Discharge Type
   Excrement is directly discharged into the municipal sewage pipeline, requiring the place to have sewage discharge conditions, commonly found in urban commercial areas or renovation projects.

2. Water-Storage Type (with a Sewage Tank)
   It has a built-in sewage tank of 100-300 liters, which only needs to be cleaned regularly. It is suitable for outdoor scenarios without sewage discharge facilities, such as mountainous areas and grasslands, but attention should be paid to matching the tank capacity with the cleaning frequency.

IV. Customized Models for Special Scenarios

1. Scenic Spot Special Type
   It strengthens anti-slip floors, ventilation systems, deodorization devices, and barrier-free facilities, taking into account both safety and comfort. Some high-end models also adopt natural ventilation design to reduce energy consumption.

2. Construction Site Reinforced Type
   Its structure adopts high-strength materials to adapt to complex terrains and frequent movement requirements, with strong impact resistance, suitable for harsh environments such as construction sites.

3. Ecological Resource Utilization Type
   It is piloted and promoted in rural revitalization projects, converting sewage into fertilizer through fecal-sewage separation technology, achieving resource recycling and conforming to the concept of sustainable development.
