Fecal Tank for Mobile Toilets
The fecal tank for mobile toilets is typically composed of a fecal sewage storage tank or a fecal sewage treatment device, designed to efficiently collect and process excrement, with the option of incorporating a fecal transfer pump for automated transfer in certain scenarios.

Core Functions of Fecal Sewage Storage Tanks/Treatment Devices
The core components of a mobile toilet's fecal tank are the fecal sewage storage tank or the fecal sewage treatment device, both of which serve similar functions but employ different treatment methods. The storage tank temporarily stores excrement through a sealed structure, suitable for short-term use scenarios (such as temporary events, construction sites), requiring regular manual cleaning. The treatment device, on the other hand, integrates biodegradation, chemical treatment, or physical separation technologies to convert excrement into harmless substances or reduce its volume, extending the cleaning cycle. For example, some eco-friendly mobile toilets use microbial decomposition technology to convert feces into water and carbon dioxide, achieving resource utilization.
Application of Fecal Transfer Pumps
In scenarios requiring frequent cleaning or large-scale use (such as major events, rural public toilets), fecal transfer pumps can be used in conjunction with mobile toilets. These pumps, centered around twisted rubber cam rotors, drive two spiral cam rotors to rotate via synchronous gears, creating a vacuum environment for self-priming and transferring feces from the storage tank to external treatment equipment or transport vehicles. Their advantages include:
- Strong self-priming capability: No need for pre-filling with water to start, adapting to the flexible deployment needs of mobile toilets;
- Constant flow rate: Stable transfer process, avoiding the risk of blockage or leakage;
- Corrosion resistance: The rubber rotor material can resist the corrosion of acidic substances in feces, extending equipment life.
Design Considerations and Practical Applications
The design of mobile toilet fecal tanks must balance hygiene, convenience, and environmental protection. For example, storage tanks should use leak-proof materials to prevent soil contamination; treatment devices should control odor emissions to meet public health standards. In livestock farming or rural settings, fecal transfer pumps can be directly connected to mobile toilets to achieve automated collection and transfer of feces, reducing manual intervention and improving operational efficiency.
In summary, the fecal tank for mobile toilets manages excrement through storage tanks or treatment devices, with the option of incorporating transfer pumps to further optimize the cleaning process. Its design should be based on a comprehensive consideration of usage scenarios, treatment needs, and environmental requirements.
