How Does Mobile Toilet Discharge Defecation

There are mainly three ways for mobile toilets to discharge defecation: direct discharge, equipment pumping, and traditional ditch discharge.

Direct Discharge Method: This is a relatively common form of discharge, mainly suitable for areas with a complete system of water supply and drainage pipes. The mobile toilet is connected to the water supply and drainage pipes through pipelines. After people use the toilet for defecation, the excrement will flow directly into the urban sewage network through the pipes and eventually enter the sewage treatment plant for centralized treatment. The advantages of this method are timely and convenient discharge, without the need to set up complex fecal storage devices inside the toilet, reducing the toilet's floor area and odor generation. However, it has high requirements for the installation environment and requires existing water supply and drainage pipes for connection, which may not be available in some remote areas or temporary construction sites.

Equipment Pumping Method: In places where there are no water supply and drainage pipes or where direct discharge is not allowed, the equipment pumping method is adopted. Usually, a vacuum sewage pump or other types of sewage pumps are installed below the main body of the mobile toilet, and these pumps are connected to the toilet's excrement collection device through pipes. When the excrement accumulates to a certain extent, the pump is started, and the excrement is sucked in by vacuum suction or the pumping action of the pump and transported through the pipes to a dedicated storage container. In addition, sealed fecal suction trucks can also be used to collect feces. These trucks are equipped with professional suction equipment to suck the feces from the mobile toilet into the storage tank inside the truck, and then transport the fecal suction truck to the sewage treatment plant for treatment. This method has high flexibility and is suitable for various places, but it requires regular arrangement of fecal suction trucks for cleaning, and the operating cost is relatively high.

Traditional Ditch Discharge Method: In some remote or poorly conditioned places, the traditional ditch discharge method may be used to discharge fecal water. A drainage ditch is dug near the mobile toilet, and the toilet's excrement is introduced into the ditch through pipes, allowing the fecal water to flow naturally along the ditch. However, this method requires regular cleaning and maintenance of the ditch to ensure its smoothness; otherwise, problems such as blockage and odor emission are prone to occur, causing pollution to the surrounding environment.
