Dongcheng Mobile Toilet Feces Treatment
There are various methods for feces treatment in mobile toilets in Dongcheng, mainly including packing, microbial degradation, flushing/recirculating flushing, chemical treatment, and collection and transportation, as detailed below:
In the packing method, an automatic packing device is installed below the toilet fixture, using plastic bags to seal and wrap the feces. Cleaning staff regularly replace the plastic bags and transport the bags filled with feces as dry waste to designated disposal points. This method does not require connection to a sewer system and is suitable for areas without municipal sewage networks, such as remote scenic spots or temporary event venues. It is simple to operate and effectively prevents odor diffusion.
The microbial degradation method involves adding specific microbial strains to the treatment device, utilizing the metabolic action of microorganisms to decompose feces into water vapor and carbon dioxide. This method requires almost no manual cleaning and only needs regular replenishment of microbial strains to maintain operation. It offers advantages such as environmental friendliness, odorlessness, and a high degree of resource utilization, commonly found in places with high environmental requirements, such as high-end scenic spots or ecological conservation areas.
The flushing method requires connection to a septic tank or municipal sewage network, using water flow to flush feces into the treatment system; the recirculating flushing method is equipped with a purification device that filters and disinfects the flushing water for reuse, only requiring regular cleaning of filter residues. Both methods rely on well-established infrastructure and are suitable for areas with a stable water supply and good sewage disposal conditions, such as city parks or large squares.
The chemical treatment method involves adding chemical agents to feces to accelerate the decomposition process and inhibit bacterial growth while reducing odor production. However, the treated wastewater contains harmful substances and must be disposed of as hazardous waste by professional agencies to avoid secondary pollution to the environment. This method is mostly used in emergency scenarios or temporary facilities, such as disaster relief sites or temporary toilets for large events.
The collection and transportation method is divided into two types: independent and row-connected. Independent mobile toilets are equipped with detachable feces storage buckets or plastic bags, which are manually cleaned and transported to disposal points on a regular basis; row-connected toilets are connected to underground feces storage tanks through pipes and are collectively pumped out by professional feces suction trucks and sent to sewage treatment plants. This method is highly flexible and suitable for areas with high passenger traffic, such as Jingshan Park during holidays, requiring the establishment of standardized collection and transportation procedures and logistical support systems.
Regardless of the method used, regular maintenance and upkeep of equipment are necessary to ensure the stable operation of the treatment system. At the same time, standardized collection and transportation procedures and logistical support mechanisms should be established to prevent feces overflow or odor diffusion and safeguard public health and safety.
