Production of Waterless Mobile Toilets
The production of waterless mobile toilets requires selecting corresponding solutions based on the technical type. The core is to replace the water-flushing function with physical, biological, or chemical means to achieve waste reduction and harmless treatment.
1. Key Points for Mechanical Packaging Production
This type uses specially made biodegradable plastic bags to seal waste. During production, a mechanical device, including an automatic tightening mechanism and a sealing module, needs to be installed below the squatting position. When a user finishes using the toilet, the mechanical device is triggered, tightening and sealing the plastic bag to form an independent waste package, which then falls into the fecal storage tank. The fecal storage tank should be designed as a detachable structure for regular removal and transportation. Key Points: The plastic bags must be biodegradable to avoid secondary pollution; the mechanical device must ensure airtightness to prevent odor leakage.
2. Key Points for Microbial Degradation Production
The core lies in the design of the degradation chamber and microbial carriers. A degradation chamber filled with microbial carriers (such as wood chips and straw) is set up below the squatting position to decompose organic matter through aerobic fermentation. During production, it is necessary to ensure good ventilation in the degradation chamber to maintain microbial activity; at the same time, a temperature monitoring system should be equipped to utilize the high temperature (usually reaching 50-70°C) generated by decomposition to kill pathogens. Key Points: The microbial strains must adapt to the local environment; the degradation chamber needs to be regularly supplemented with carriers to avoid a decrease in decomposition efficiency.
3. Key Points for Foam Sealing Production
A foam layer is generated by mixing an air pump with foaming liquid to cover the surface of the squatting pan. During production, an air pump, a foaming liquid storage tank, and a mixing device need to be installed to ensure uniform coverage of the pan with foam to prevent the splashing of excreta. After the excreta fall in, they slide into the pipe below. A single foaming only consumes about 0.1 liters of liquid, significantly saving water. Key Points: The foaming liquid must have low-foaming and odor-suppressing properties; the air pump must operate stably to avoid foam interruption.
4. Key Points for Vacuum Suction Production
A vacuum pump is used to create negative pressure in the pipe to instantly suck in waste. During production, a main pipe and a vacuum pump connection system need to be designed to ensure rapid transportation of waste to the treatment tank. This type is suitable for high-traffic scenarios, but the vacuum pump requires regular maintenance to prevent blockages. Key Points: The pipes must be smooth and free of dead corners to avoid waste residue; the power of the vacuum pump must match the usage scenario.
5. Key Points for Chemical Agent Production
Chemical agents (such as sodium hypochlorite and biological enzymes) are added to the fecal storage tank to decompose excreta and suppress odors through chemical reactions. During production, environmentally friendly agents should be selected to avoid harm to the environment; the fecal storage tank must be sealed to prevent agent volatilization. Key Points: The agents must be regularly replaced to ensure decomposition effects; the fecal storage tank must be equipped with a liquid level monitor to prevent overflow.
System Expansion: Some waterless toilets can be equipped with wall-attached jet technology, which uses high-pressure water flow to assist in waste transportation, achieving full-process automation control, with features such as freeze protection and intelligent operation, suitable for extreme climate scenarios.
