Yiyang Mobile Toilet Fecal Extraction

Admin October 05, 2026

The fecal extraction service for mobile toilets in Yiyang mainly relies on professional equipment and technology, with the core being the efficient cleaning achieved through vacuum suction trucks, and tailored plans need to be formulated according to the type of toilet.

1. Core Cleaning Technology: Negative Pressure Operation of Vacuum Suction Trucks
The core equipment for fecal extraction from mobile toilets in the Yiyang area is vacuum suction trucks. These trucks generate strong negative pressure by driving a vacuum pump with an engine, converting solid and semi-solid excreta and sewage in septic tanks or toilets into a fluid state. This process overcomes the limitations of traditional manual cleaning. The negative pressure suction force can reach above -0.08MPa, enabling it to reach deep into the bottom of the tank to suck out sediment and avoid residue. Professional teams will evaluate the tank structure in advance, adjust the angle of the suction pipe and the suction intensity to ensure thorough cleaning and prevent damage to the tank due to sudden pressure changes. In addition, the suction trucks are equipped with sealed tanks and anti-overflow devices to prevent secondary pollution during transportation.

2. Fecal Extraction Plans for Different Types of Mobile Toilets

  • Flush-type mobile toilets: These toilets usually have standardized sewage outlets, and excreta is directly discharged into the septic tank after being flushed with water. During fecal extraction, the inlet valve should be closed first to prevent new sewage from entering the tank and interfering with the operation, and then the suction pipe should be connected to the sewage outlet for extraction. If the capacity of the septic tank is small (e.g., 2-3 cubic meters), it is recommended to extract the feces every 1-2 weeks; for larger capacities (above 5 cubic meters), the interval can be extended to 3-4 weeks, depending on the frequency of use.
  • Simple mobile toilets: Most of them are designed as dry or packaged types, with excreta stored in solid or semi-solid form in a collection tank. For fecal extraction from these toilets, the sealed cover of the collection tank should be opened first, and professional tools should be used to break up the agglomerated materials before extraction with a suction pipe. If the leasing service includes basic maintenance, the supplier may regularly replace the collection bags or disinfect them, but fecal extraction operations still require professional teams to avoid the spread of odors or pathogens.

3. Service Process and Safety Regulations
Before starting work, professional teams will wear protective suits, masks, and gloves and set up warning signs in the work area. After cleaning, the inside of the tank should be flushed with high-pressure water to remove residues, and biological degradants should be sprayed to accelerate the decomposition of organic matter and reduce odors. If it involves mobile toilets in public areas, the surrounding ground should also be disinfected to ensure environmental hygiene standards are met.
