Mobile Toilet Without Sewage System
In areas without sewage networks, options include resource-utilization, physical-sealing, traditional-transitional, and zero-emission mobile toilets, or innovative solutions like the Jiahe treatment system. Details are as follows:
Resource-Utilization Type: Microbial degradation toilets use aerobic fermentation by microorganisms to break down excreta into water and carbon dioxide, with a small amount of dry residue usable as organic fertilizer, achieving zero sewage discharge and resource recycling. They are suitable for eco-protected areas, high-end scenic spots, and other places emphasizing environmental protection, but have higher costs and require heated models in cold regions.
Physical-Sealing Type: Waterless packing toilets seal waste with biodegradable film and store it in a fecal storage tank, being waterless, odorless, and simple in structure, but requiring regular replacement of consumables, suitable for temporary construction sites and emergency events. Recirculating water-flush toilets treat sewage with microorganisms or chemicals for recirculating flushing, saving water and providing a flush-like experience, but have higher initial investment and water quality maintenance costs, suitable for fixed places with long-term water shortages but a desire for a water-flush experience.
Traditional-Transitional Type: Three-chamber septic tank toilets preliminarily treat sewage through three-stage anaerobic fermentation and sedimentation, being technically mature and low-cost, but requiring regular sewage suction and removal. Improper siting or delayed removal can easily pollute groundwater, suitable for self-use by farmers or places sensitive to cost and able to arrange sewage suction.
Zero-Emission Solution Type: Source-separation toilets collect urine and feces separately at the source, reducing treatment difficulty and enabling resource recovery, but the facilities are not yet widespread and require user habit adjustments, suitable for cutting-edge demonstration areas, research projects, and other places with resource recovery requirements.
Other Innovative Solutions: The Jiahe treatment system uses waterless treatment technology, converting excreta into harmless substances through biological degradation and solid-liquid separation, with a water-saving rate of up to 90%. Equipped with smart sensors, it offers advantages such as environmental protection, economy, odorlessness, and strong adaptability, and provides one-stop services, suitable for outdoor scenes with water shortages.
