Mobile Public Toilet Drainage Direction

There are several main drainage directions for mobile public toilets:

Conventional Flush Type: This type of mobile public toilet requires connection to water supply and sewage pipes. During use, the sewage discharge process is initiated through manual operation or automatic sensing devices. The sewage flows along the pipes to the septic tank, where it undergoes preliminary sedimentation and decomposition. In areas with well-developed municipal facilities, the sewage may also be directly discharged into the municipal sewer network and enter the urban sewage treatment system for further purification.

Vacuum Sewage System: It operates based on the principle of negative pressure. A vacuum pump is installed inside the toilet. After the user finishes using it, the vacuum pump starts, generating negative pressure to quickly suck the sewage and waste into a dedicated collection container. The advantages of this method are fast sewage discharge and effective reduction of odor emission. When the collection container is full, it is handled by professional personnel.

Water Storage Sewage System: It uses water flushing to discharge waste into a storage tank. During toilet use, each flush pushes the excreta into the storage tank for storage. When the storage tank reaches a certain capacity, i.e., when it is full, staff need to be arranged to clean and replace the storage tank to ensure the normal use of the toilet.

Direct Water Flush Type: Relying on the strong flushing force of water, excreta is directly discharged into the urban sewer network or the septic tank. This method has a relatively simple structure, but it requires a stable water source and a good connection to the sewer network or the septic tank to ensure the smooth discharge of excreta.

Packaging Type: The excreta is packaged and sealed in biodegradable plastic bags. When the bag is full, staff remove the full bag and replace it with a new one. This method does not require connection to water supply and sewage pipes and is suitable for places with a lack of water sources or where it is inconvenient to connect to the pipe network.

Foam Sealing Type: Inside the toilet, foam covers the excreta, serving to block odors and provide lubrication, allowing the excreta to smoothly enter the sewage storage tank. When the sewage storage tank reaches its capacity limit, a sewage suction truck is used to suck out and dispose of the waste in the tank.

Microbial Degradation Type: By cultivating specific microbial communities inside the toilet, these microorganisms can decompose the organic matter in the excreta into harmless water, carbon dioxide, and organic fertilizers, achieving on-site treatment and resource utilization of the excreta.
