Hubei Mobile Toilet Fecal Treatment

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

Microbial Treatment: Microbial mobile toilets convert organic waste into harmless substances by introducing specific microbial communities. During this process, it is necessary to screen microorganisms with different functions to work in synergy based on the organic load in the target environment, such as cellulose-decomposing bacteria and fat-decomposing bacteria. At the same time, the ratio and dosage concentration of microbial strains should be calculated according to the fluctuation range of environmental temperature and humidity. The selection of carrier materials is also crucial; porous ceramics, activated carbon, or synthetic fiber fillers should match the target strains to maintain microbial community stability. In addition, gas-liquid balance control maintains the dominance of aerobic bacteria and inhibits odor generation through timed oxygen supply via a "segmented aerobic system".

Water-Flush and Non-Water-Flush Suction Types: These mobile toilets receive excreta in sewage tanks and require timely suction to avoid overflow. They are suitable for places with high hygiene requirements and where regular suction operations can be carried out.

Circulating Water-Flush Types: Equipped with intermittent aerobic and anaerobic treatment devices, biological strains are added to accelerate fermentation and decomposition, and the water is recycled for flushing toilet fixtures. This method not only saves water resources but also achieves effective fecal treatment.

Dry Packing Types: Degradable plastic bags are used to receive excreta, which are then collected and transported to treatment plants for disposal. This method is simple to operate and convenient for subsequent treatment, but attention should be paid to the degradability and environmental friendliness of the plastic bags.

Foam Sealing Types: Foam generated by a foaming liquid mixture is used instead of flushing water to save water resources. Foam-sealing mobile toilets effectively prevent the emission of odors through the covering and sealing effect of the foam while reducing water consumption.
