Mobile Toilet Feces Structure

The structure for handling feces in mobile toilets varies depending on the type. Here is an introduction to the specific feces-handling structures of various mobile toilets:

Water-flush and Non-water-flush Suction Mobile Toilets: The structure of non-water-flush mobile toilets is relatively simple, with a sewage tank placed at the bottom of the toilet to directly receive the excreta of users. Water-flush mobile toilets are equipped with a water-flush device. Generally, the water tank is placed on top of the toilet and connected to the sanitary ware through pipes. After use, water flows from the water tank to flush the sanitary ware, and the excreta is flushed into the sewage tank placed at the bottom of the toilet.

Recirculating Water-flush Mobile Toilets: This type of mobile toilet is equipped with an intermittent aerobic and anaerobic treatment device for fecal sewage and adds biological strains. Using biofilm technology, it accelerates the fermentation and decomposition of fecal sewage. After that, through a filtration device, the treated fecal sewage is recirculated for flushing the toilet sanitary ware, achieving water resource recycling.

Dry-packing Mobile Toilets: This type does not have a water-flush device. Biodegradable plastic bags are placed under the sanitary ware to receive excreta. For each use, the system automatically replaces it with a new plastic bag to ensure hygiene. After use, the plastic bags are collected and transported to a treatment plant for disposal.

Foam-sealing Mobile Toilets: Foam generated by a foaming liquid mixture is used instead of toilet flushing water. There are foam channels on the side walls of the toilet fixtures. Compressed air is sent through compressed air delivery pipes to a foam activator, causing the foam emitted from the foam tank to cover the inside of the toilet bowl through the foam channels, preventing odor emission and providing a cleaning effect.

Microbial Mobile Toilets: Excreta enters a solid-liquid separation device through an automatically opening toilet bowl. This device can filter urine and separate feces. After separation, the feces 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 bacteria, they decompose and are finally separated in the form of CO2 and H2O, with a degradation rate of ≥99%.
