How do the mobile toilets produced by Dalian Pohang Environmental Protection Equipment Co., Ltd. handle excrement?
1. Flush and non-flush suction mobile toilets
The flush mobile toilet has a water flushing device. Generally, the water tank is placed on the top of the toilet, and there is a sewage tank at the bottom of the toilet, but there is no water. Flush mobile toilets do not have a flushing device, and the sewage tank installed at the bottom of the toilet directly receives the user's excrement. Since the sewage tanks of these two types of mobile toilets have a small capacity, they need to be pumped in time when the specified number of people are used, otherwise overflow events are prone to occur and the pumping frequency is high.
2． Circulating water flushing mobile toilet
This type of mobile toilet is equipped with intermittent aerobic and anaerobic treatment devices for fecal sewage. In addition, biological bacteria are added and biofilm technology is used to accelerate the fermentation and decomposition of fecal sewage. The treated fecal sewage is then recycled through the filtering device and used to flush toilet sanitary ware. It is characterized by the use of advanced fecal sewage treatment technology, which saves precious water resources and reduces the number of fecal sewage pumping times. The environmental protection concept is fully demonstrated.
3． Dry packaged mobile toilet
This type of mobile toilet does not have a flushing device, and excrement is collected by a biodegradable plastic bag placed at the bottom of the sanitary ware. Every time a person uses it, a new plastic bag is automatically replaced. , after use, the plastic bags will be collected and transported to the treatment plant for disposal. The characteristic of this kind of mobile toilet is that it does not use water to flush, which saves water resources and makes waste collection more convenient.
4. Foam-blocking mobile toilets
Foam-blocking mobile toilets use foam produced by a foaming liquid mixture to replace toilet flushing. When in use, there is a foam channel on the side wall of the toilet, and the foam toilet is The compressed air is sent to the foam initiator through the compressed air delivery pipe, so that the foam emitted from the foam box covers the inside of the toilet through the foam channel without odor. Foam is used instead of water to flush the toilet. This system can meet the foaming water demand by collecting hand clean water. , thus maximizing water conservation.
5. Microbial mobile toilet
The excreta from the microbial mobile toilet enters the solid-liquid separation device by automatically opening the bedpan. This device can filter the urine, push the stool out, separate it, and then process it separately. The feces is separated and then enters the fermentation tank. The initial ingredients, wood chips, biological strains and feces are mixed through the rotation of the screw propeller. They are decomposed under the action of microbial bacteria and separated in the form of CO2 and H2O. The degradation rate is ≥99; the urine is filtered Then it enters the comprehensive urine treatment system, where it is processed into reclaimed water to flush back into the urinal through aeration, evaporation, decolorization and other processes, forming a cycle.
