Wuxi Mobile Toilet Treatment
The treatment technologies for mobile toilets in Wuxi mainly include five types: water-flush combined with sewage storage tanks, biodegradation, chemical treatment, vacuum suction with water-saving flushing, and waterless packaging and foaming technology. Details are as follows:
Water-flush combined with sewage storage tank unit: This technology achieves temporary storage and transfer of excreta through sewage storage tanks. The volume design of the sewage storage tank directly affects the cleaning cycle, with a larger volume resulting in longer intervals between single cleanings. The material must have anti-leakage properties and may include preservatives to inhibit microbial activity and reduce odors. This technology only provides storage functionality and requires regular cleaning, making it suitable for scenarios with high hygiene requirements and cleaning capabilities.
Biodegradation treatment unit: By introducing active microbial communities, excreta decomposition is accelerated under suitable temperature, humidity, and nutrient conditions. Internal mixing or aeration devices are equipped to increase oxygen content and promote the work of aerobic bacteria, with the final products being carbon dioxide, water, and a small amount of residue. This technology significantly reduces waste volume and cleaning frequency but requires control of environmental parameters to ensure microbial activity, making it suitable for long-term use and scenarios with high environmental protection requirements.
Chemical treatment unit: Disinfection, deodorization, and partial decomposition are achieved through the addition of chemical agents. The agent formula contains aldehydes, surfactants, and odor-masking fragrances, which can quickly inhibit pathogens and eliminate odors. However, strict management of agent replenishment is required to avoid secondary pollution from excessive use, and waste liquid must be treated according to environmental protection regulations, making it suitable for emergency or short-term high-density use scenarios.
Vacuum suction with water-saving flushing unit: Using high-pressure pneumatic or vacuum technology, flushing can be completed with less than 0.5 liters of water, and waste is forcefully drawn into sewage tanks. This technology has extremely high water-saving efficiency, reducing dependence on cleaning water sources, and is suitable for scenarios with inconvenient water supply or limited water consumption, such as arid regions or temporary events.
Waterless packaging and foaming technology: This is a waterless flushing type that uses biodegradation or vacuum collection systems and does not require connection to municipal water supply and sewage pipelines. Excreta is wrapped in foaming agents and sealed for storage, reducing odor diffusion, and is particularly suitable for large-scale events such as outdoor music festivals and marathons, as well as temporary facilities for urban road construction and scenic spots.
