It has the advantages of mobility, modularity, and convenient transportation, and its design follows the principles of easy mobility and cost-effectiveness. The following is an introduction from different aspects:

Structure and Materials

The frame structure of a mobile toilet is composed of welded steel. The bottom is welded with channel steel or I-beams, and square steel is used for the columns. Wall materials such as color-coated steel sheets are installed on the wall foundation. This frame structure meets the requirements for lifting.

Types and Characteristics

• Packaged Mobile Toilet:

The packaging bag on the squatting surface is renewed, and a sealing device prevents odor from escaping. An alarm is triggered when the degradable bags are used up.
  • Technical Advantages: No need for upper and lower pipes or water flushing; the mechanical packaging type does not require electricity. Feces are sealed and treated centrally, causing no environmental pollution. There is no odor leakage or air pollution. It is easy to operate, small in size,不受地域、环境、温度限制 (not restricted by location, environment, or temperature), has good ventilation, is inexpensive, has simple technology, and requires low investment.
