Mobile Toilet Feces Cleaning

There are various methods for cleaning feces in mobile toilets, including water-flush and non-water-flush suction types, circulating water-flush types, dry-packing types, foam-sealing types, microbial types, and other treatment methods.

1. Water-flush and Non-water-flush Suction Types: Water-flush mobile toilets are equipped with a water-flushing device, with a water tank placed on top and a sewage tank at the bottom; non-water-flush types have no flushing device and directly receive excreta in the bottom sewage tank. The sewage tanks of these two types of toilets have limited capacity. When the number of users reaches a specified value, timely suction and cleaning are required to ensure the normal use and hygiene of the toilets.
2. Circulating Water-flush Type: This type of toilet is equipped with an intermittent aerobic and anaerobic treatment device for fecal sewage, and biological strains are added. Through biofilm technology, the fermentation and decomposition of fecal sewage are accelerated. After treatment by a filtration device, the treated water is recycled for flushing the toilet, achieving effective utilization of water resources.
3. Dry-packing Type: This type of toilet has no water-flushing device. Excreta are received by a biodegradable plastic bag placed under the sanitary fixture. Each time a person uses it, the system automatically replaces the plastic bag with a new one. After use, the plastic bags are collected and transported to a treatment plant for disposal, avoiding waste and pollution of water resources.
4. Foam-sealing Type: Foam generated by a foaming liquid mixture is used instead of toilet flushing water. The foam covers the inside of the toilet bowl, effectively isolating odors. The system can meet the water demand for foaming by relying solely on collected hand-washing water, saving water resources and maintaining the cleanliness and hygiene of the toilet.
5. Microbial Type: Excreta enter a solid-liquid separation device through an automatically opening toilet bowl. The feces are separated and enter a fermentation tank. Through the rotation of a screw propeller, initial ingredients, sawdust, biological strains, and feces are mixed. Under the action of microbial strains, decomposition occurs, achieving harmless treatment of excreta.
6. Other Treatment Methods: These include chemical treatment, anaerobic digestion, compression and storage, multi-functional sewage outlets, and mechanical treatment. Each of these methods has its own characteristics. For example, chemical treatment uses chemical agents to decompose and eliminate excreta; anaerobic digestion utilizes microorganisms to decompose excreta to produce biogas and fertilizer; compression and storage reduce the volume of excreta and delay treatment needs; multi-functional sewage outlets are equipped with manual cleaning functions; mechanical treatment involves using specialized equipment for solid-liquid separation, decomposition, and disinfection of feces.
