Microorganisms in Mobile Toilets
The microbial technology in mobile toilets primarily achieves harmless treatment of excrement through microbial decomposition, featuring water conservation, environmental protection, and strong adaptability.
1. Principles of Microbial Degradation Technology Microbial degradation mobile toilets utilize specific bacterial strains to decompose organic matter in feces, converting it into carbon dioxide, water, and a small amount of harmless substances, enabling treatment without water flushing. For example, bacterial strains decompose components such as proteins and fats in excrement through metabolic processes, achieving harmless treatment. This technology is particularly suitable for waterless environments, high-altitude deserts, and other water-scarce areas, addressing the traditional toilet's reliance on water resources.
2. Microbial Applications in Ecological Public Toilets Ecological public toilets are based on solid-liquid separation technology, achieving excrement treatment through microbial decomposition. Initial operation requires a one-time injection of 70-80 kilograms of water to activate the bacterial community. During subsequent operation, microorganisms continuously decompose organic matter in the solid portion after solid-liquid separation, while the liquid portion can also be discharged to standard after treatment. These toilets feature water conservation, mobility, and waterless flushing, making them suitable for temporary events or remote areas.
3. Composition and Operation of Microbial Degradation Devices Microbial degradation eco-friendly toilet devices include fermentation degradation tanks, mechanical transmission devices, and electrical PLC constant temperature and humidity control devices. The fermentation degradation tank is filled with microbial bacterial strains and carriers, and excrement and bacterial filler are stirred through mechanical intermittent forward and reverse transmission, promoting thorough contact between microorganisms and excrement and accelerating the decomposition process. The gases produced during decomposition are treated to meet discharge standards, and solid residues are reduced to extremely low levels.
4. Energy Consumption and Maintenance Costs This technology consumes approximately 3-5 kilowatt-hours of electricity per day (depending on the region and number of users), primarily used to maintain a constant temperature and humidity environment within the fermentation degradation tank. The interval for bacterial strain replacement is determined based on the number of users, typically ranging from 3-6 months, with costs approximately 300 yuan (domestic bacterial strains) to 500 yuan (imported bacterial strains) per toilet stall. Overall operating costs are low, and the environmental benefits are significant.
