Small Fecal Tank for Mobile Toilets

The small fecal tank in mobile toilets generally refers to the relatively small-sized part of the fecal sewage storage tank, which is a key component for fecal collection and storage in mobile toilets. The following is an introduction from its functions, types, and characteristics:

Functions

The main function of the small fecal tank is to collect and store feces and sewage generated during the use of mobile toilets. In water- and electricity-free packaged mobile toilets, the packaged squatting pan directly packages the feces into the small fecal tank, preventing fecal leakage and maintaining a relatively clean internal environment of the toilet. In some mobile toilets equipped with simple treatment devices, the small fecal tank serves as a preliminary storage container for fecal sewage. After reaching a certain amount, the fecal sewage is transferred to a specialized treatment site for further treatment through manual or automatic means, preventing the indiscriminate discharge of feces from polluting the environment.

Types

• Packaged Small Fecal Tank: Used in conjunction with a packaged squatting pan, it generally uses biodegradable plastic bags to package feces. After a user defecates, a mechanical device wraps the feces in the plastic bag and drops it into the small fecal tank. This type of small fecal tank has a relatively simple structure and low cost, making it suitable for places with not particularly high hygiene requirements and low usage frequencies.
• Storage Small Fecal Tank: Mainly used for storing untreated fecal sewage, it usually has a large volume to meet long-term usage needs. Its material is generally selected from corrosion-resistant and well-sealed materials, such as stainless steel or high-strength plastics, to prevent fecal sewage leakage and odor emission.

Characteristics

• Portability: The design of the small fecal tank usually takes into account the portability requirements of mobile toilets. It has a relatively small volume and light weight, facilitating transportation and installation. In places such as temporary events and construction sites, mobile toilets and their small fecal tanks can be quickly arranged and dismantled as needed.
• Sealability: To ensure that fecal sewage does not leak and reduce odor emission, the small fecal tank has good sealing performance. A sealing strip or snap-fit design is usually adopted between the tank body and the lid to ensure no leakage occurs during storage and transportation.
• Easy Cleaning: The design of the small fecal tank also considers the convenience of cleaning. Some small fecal tanks adopt a detachable structure, making it easy to remove the tank body from the mobile toilet for cleaning; some are equipped with flushing devices, allowing the use of clean water to flush the inside of the tank body during cleaning and improving cleaning efficiency.
