Structure of Mobile Environmental Toilet

The structure of a mobile environmental toilet mainly includes basic functional components, mobile structure, internal supporting facilities, and walls and roofs, as detailed below:

Basic Functional Components

The fecal sewage storage and treatment system is the core part, typically consisting of a fecal sewage storage tank or disposal unit. The storage tank collects excreta to prevent direct discharge from polluting the environment; some designs are equipped with disposal units that perform preliminary treatment of feces through biological degradation or chemical treatment, reducing odors and bacterial growth. Sanitary ware is also a basic component, such as toilets, which provide convenient facilities for users to excrete. Their design needs to consider compatibility with the overall structure and user comfort.

Mobile Structure

To enable flexible movement of the toilet, mobile devices are essential. A common approach is to install universal wheels at the bottom. For example, in some homemade cases, universal wheels are installed at the bottom of a water storage tank, allowing the toilet to be easily moved to different locations to meet temporary use or site change requirements.

Internal Supporting Facilities

The water tank is used to store clean water and is connected to an inlet pipe to provide water for flushing toilets and washing hands. Washing facilities include washbasins, which can be made from stainless steel basins or plastic sheets and connected to the drainage system through pipe caps and pipes, facilitating hand washing for users. Some designs also include shower hoses and brackets to provide more comprehensive cleaning functions.

Walls and Roof

Walls serve to separate spaces and protect privacy. In some homemade cases, the doorway is created by cutting the tank body, and plastic soft boards or wooden boards are inserted as partitions, ensuring structural stability while providing flexibility. The roof can be covered with the upper part of a water storage tank or wooden boards, providing shelter from wind and rain while enhancing the overall aesthetic appeal of the toilet. Additionally, the door is made of wooden boards or honeycomb panels and is equipped with hinges and door handles for easy opening and closing, ensuring user privacy.
