Where Does the Water from Mobile Toilets Go?
The water discharge methods for mobile toilets vary depending on their type, primarily including discharge into septic tanks or municipal sewage networks, suction into collection containers, discharge into storage tanks, and discharge after conversion into harmless substances.
Conventional flush-type mobile toilets are the most common type. They require connection to water supply and drainage pipes, using manual or automatic sensing for waste discharge. During use, sewage is directly discharged into septic tanks or municipal sewage networks. This discharge method requires that the design of the sewage system must comply with relevant national standards, such as the 'Urban Public Toilet Design Standard CJJ14-2016', to ensure smooth and safe sewage discharge. At the same time, to prevent blockages and odors, septic tanks need to be cleaned regularly.
Mobile toilets with vacuum sewage systems utilize negative pressure principles for waste discharge. They use vacuum pumps to suck sewage and waste into collection containers. When the sewage reaches a preset water level, the vacuum pump automatically starts, further processing or discharging the sewage. This discharge method is efficient and environmentally friendly, suitable for places with high sewage discharge requirements.
Storage-type sewage system mobile toilets discharge waste into storage tanks through flushing. When the storage tank is full, it needs to be cleaned and replaced. This discharge method is suitable for places with sufficient water sources and easy cleaning, such as some large event venues or temporary construction sites.
In addition to the above common discharge methods, some mobile toilets adopt more advanced sewage discharge technologies. For example, some mobile toilets use biodegradation technology to convert organic matter in sewage into harmless substances before discharge, which is both environmentally friendly and efficient. Additionally, some mobile toilets use foam-sealing sewage systems, utilizing foam produced by foam liquid mixtures instead of flushing, thereby reducing water consumption and sewage production.
