Mobile Toilet Excrement Collection
The collection method of excrement in mobile toilets mainly depends on the toilet type, and different types have their own characteristics in collection methods.
Flush Type: These mobile toilets are usually equipped with a water tank or can be connected to an external water source. When in use, the excrement is flushed into a collection tank or septic tank below through flushing. The collection tank generally has a large capacity and can hold a certain amount of sewage. When the collection tank is almost full, the sewage can be pumped out and transported for treatment using specialized sewage pumping equipment; the septic tank will carry out preliminary sedimentation and decomposition of the sewage, and then be cleaned up uniformly later.
Waterless Packing Type and Dry Packing Type: The principles of these two are similar, both using biodegradable plastic bags to collect excrement. The waterless packing type automatically packs the feces through a mechanical device without the need for flushing, sealing the waste in the bag for centralized collection; the dry packing type has no flushing device, and the excrement is directly received by a biodegradable plastic bag placed under the sanitary ware. Each time one person uses it, another new plastic bag is automatically replaced. After use, the plastic bags are collected and processed centrally. This method avoids the waste of water resources, and the plastic bags are biodegradable, which is relatively friendly to the environment.
Eco-Friendly Type: It adopts microbial degradation or solid-liquid separation technology to carry out preliminary decomposition of feces in the tank. Microbial degradation uses specific microbial strains to decompose and convert the organic matter in feces into harmless substances; solid-liquid separation separates the solid and liquid in feces for separate treatment, reducing the difficulty and pollution of subsequent treatment.
Flush and Non-Flush Suction Type: The flush-type mobile toilet has a flushing device inside, with the water tank placed on the top of the toilet and a sewage tank at the bottom. After flushing, the sewage enters the sewage tank; the non-flush type has no flushing device, and the excrement is directly received by the sewage tank at the bottom. When the sewage tank is full, a suction device is used to pump out and transport the waste.
Circulating Flush Type: It is equipped with an intermittent aerobic and anaerobic treatment device for fecal sewage, with the addition of biological strains. It uses biofilm technology to accelerate the fermentation and decomposition of fecal sewage, and then through a filtration device, the treated fecal sewage is recycled for flushing the toilet sanitary ware, achieving the recycling of water resources.
Foam Sealing Type: It uses the foam generated by the foaming liquid mixture instead of toilet flushing. The foam covers the inside of the toilet bowl, and the urine is filtered and then treated, reducing the consumption of water resources and the amount of waste generated.
