Mobile Toilet Fecal Treatment Technology
Mobile toilet fecal treatment technology mainly includes five types: water-flush and non-water-flush suction type, circulating water-flush type, dry packing type, foam sealing type, and microbial type.
The water-flush and non-water-flush suction types are relatively basic treatment methods. Water-flush mobile toilets use a combination of a top water tank and a bottom sewage tank, utilizing a water-flush device to flush excrement into the sewage tank; non-water-flush types directly receive excrement in the bottom sewage tank. Both methods require regular suctioning of the sewage tank to prevent overflow and are suitable for places with high hygiene requirements and suctioning capabilities.
The circulating water-flush technology is more advanced. It employs biofilm technology, decomposing fecal sewage through aerobic and anaerobic treatment devices, and adding microbial strains to accelerate the fermentation process. The treated sewage is filtered and then recycled for toilet flushing, significantly reducing water consumption and the frequency of suctioning, making it suitable for areas with water scarcity or long-term use scenarios.
The dry packing technology completely avoids water usage. It uses biodegradable plastic bags to receive excrement, automatically replacing them with new bags after each use. These plastic bags are then transported to a treatment plant for disposal, making them ideal for water-scarce areas or temporary events, being both environmentally friendly and convenient.
The foam sealing technology utilizes foam generated by mixing a foaming agent with water to cover the inside of the toilet bowl, effectively blocking odors and lubricating for flushing. This system requires only a small amount of hand-washing water to operate, achieving significant water-saving effects while maintaining fresh air in the toilet, enhancing the user experience.
The microbial technology is a resource recycling treatment method. It separates urine and feces using a solid-liquid separation device, with feces mixed with sawdust and microbial strains for fermentation and decomposition into carbon dioxide and water; urine is treated through aeration, decolorization, and then recycled for flushing, with a degradation rate of over 99%, achieving maximum resource utilization.
