Henan Mobile Toilet Fecal Treatment
There are various fecal treatment methods for mobile toilets in Henan, including water-flush and non-water-flush suction types, circulating water-flush types, dry packing types, foam sealing types, chemical treatment, anaerobic digestion, mechanical treatment, vacuum suction types, biodegradation types, and regular suction and centralized treatment, etc.
Water-flush and Non-water-flush Suction Types: Water-flush types use a water-flushing device to flush excrement into the bottom sewage tank, while non-water-flush types directly receive excrement in the sewage tank. Due to the limited capacity of the sewage tank, both require regular suction to prevent overflow, making them suitable for short-term or low-traffic scenarios.
Circulating Water-flush Type: Through intermittent aerobic and anaerobic treatment devices, biological bacteria are added to accelerate fermentation and decomposition, and then filtered water is recycled for toilet flushing. This method reduces suction frequency and conserves water resources, making it suitable for places with water scarcity or long-term use requirements.
Dry Packing Type: Degradable plastic bags are used to receive excrement, which are automatically replaced with new bags after each use and then collected and transported to a treatment plant. This method does not require water flushing and is easy to operate, making it suitable for areas without water sources or with high environmental protection requirements.
Foam Sealing Type: Foam generated by a foaming liquid mixture covers the inside of the toilet bowl, isolating odors and replacing water flushing. Only hand-washing water needs to be collected to meet the foaming demand, maximizing water conservation and making it suitable for arid or water-scarce regions.
Chemical Treatment: Chemical agents are added to decompose excrement, control odors, and promote decomposition. The treated excrement is further processed through specialized equipment or flows into the sewage system, making it suitable for places with high hygiene requirements.
Anaerobic Digestion: Microorganisms are used to decompose excrement, producing biogas (usable for energy) and fertilizer (usable for agriculture or horticulture), reducing volume and delaying treatment needs, achieving resource recycling, and making it suitable for rural areas or ecological scenic spots.
Mechanical Treatment: Specialized equipment is used for solid-liquid separation, decomposition, and disinfection, reducing environmental impact and ensuring hygiene and safety, making it suitable for places with strict environmental protection requirements.
Vacuum Suction Type: Negative pressure suction technology is adopted, with extremely low water consumption and almost no odor, making it suitable for high-end scenic spots or Class I tourist public toilets. Smart sensing devices can be installed to enhance the user experience.
Biodegradation Type: Microorganisms are used to decompose feces on-site, reducing fecal volume and extending the collection cycle, making it suitable for mountainous areas, campsites, or scenic spots without water supply and drainage systems. Photovoltaic systems can be optionally installed to provide energy.
Regular Suction and Centralized Treatment: After the sewage tank is full, professional personnel suction the excrement and transport it to a specialized treatment center for harmless treatment, which can also be converted into organic fertilizer for resource recycling, making it suitable for urban or densely populated areas.
