Nanjing Mobile Toilet Sewage Disposal
The sewage disposal methods for mobile toilets in Nanjing mainly include direct-discharge pocket, water-flush storage, waterless packing, and seat-type direct-discharge types. Here is a detailed introduction:
Direct-discharge pocket sewage disposal method: The direct-discharge pocket is a common sewage disposal form for mobile toilets in Nanjing. This design is usually equipped with a dedicated sewage pocket. During toilet use, excrement directly falls into the sewage pocket. When the sewage pocket reaches a certain capacity, it needs to be manually cleaned and replaced. The sewage pocket filled with excrement is taken out and replaced with a new, clean one to ensure the normal use of the toilet. This method is relatively simple to operate and is suitable for places with a not particularly high frequency of use and relatively low requirements for sewage disposal.
Water-flush storage sewage disposal method: Water-flush storage mobile toilets flush excrement into a storage container through water flushing. They use water from a water tank to flush the toilet after each use, sending the excrement into a storage tank below. The storage tank generally has a certain capacity and can store a certain amount of excrement. When the storage tank is almost full, a specialized sewage suction truck is required to pump out the excrement from the storage tank and transport it to a designated treatment site for further processing. This sewage disposal method is relatively hygienic and can effectively reduce odor emissions. It is suitable for places with a large flow of people and high requirements for sanitary conditions.
Waterless packing sewage disposal method: Waterless packing mobile toilets do not require water for flushing. They use special biodegradable plastic bags. After each use, the excrement is automatically packed and sealed inside the plastic bag. This packing method can effectively isolate odors and prevent excrement leakage. When the plastic bag is full, the entire packed plastic bag just needs to be taken out and replaced with a new one. This method has the advantages of water conservation and environmental protection and is particularly suitable for areas with a scarcity of water resources or where it is inconvenient to connect to a water source.
Seat-type direct-discharge sewage disposal method: The sewage disposal principle of seat-type direct-discharge mobile toilets is similar to that of the direct-discharge pocket, but it places more emphasis on the design of the seat-type toilet. Excrement is directly discharged through pipes into the treatment system or collection container below. This design usually incorporates relatively advanced sewage pipes and treatment devices, enabling more efficient discharge of excrement, reducing blockages and odor problems, and providing a more comfortable toilet experience for users.
In addition, in popular areas of Nanjing, newly added mobile public toilets strictly implement the service standards of "no odor, paper available, and good facilities" to ensure the normal functioning of sewage disposal and other related functions, providing a good toilet experience for citizens and tourists.
