Zhengding Environmental-Friendly Mobile Toilet

The Zhengding environmental-friendly mobile toilet is a well-structured mobile toilet that employs advanced technology to treat waste and control odors.

Manufacturers and Technology

In the Zhengding area of Shijiazhuang, there are manufacturers of environmental-friendly toilets, such as Baoding Shuangteng Environmental Protection Technology Co., Ltd. The core of the environmental-friendly toilets they produce lies in the use of microbial degradation technology to treat waste. This involves creating an environment suitable for the survival of specific microbial communities. These microbes feed on the organic matter in the waste, breaking it down into carbon dioxide, water, and a small amount of inorganic salts. The equipment is filled with sawdust, straw, or specially designed carriers to adjust the carbon-to-nitrogen ratio and provide attachment areas for the microbial communities. Manufacturers need to precisely control the temperature, humidity, and ventilation to ensure the stable activity of the microbial communities.

Pathogen Elimination

Human waste contains a large number of intestinal pathogens and parasite eggs. Manufacturers in Zhengding address this issue in two ways. First, they utilize the biological heat generated during the microbial degradation process to raise the internal temperature to 55 - 70 degrees Celsius and maintain it for a certain period to inactivate most pathogens. Second, they add auxiliary sterilization mechanisms, such as introducing alkaline substances or acids into the urine storage unit to inhibit bacterial growth by altering the pH value.

Odor Control

Odors mainly come from ammonia and hydrogen sulfide. Manufacturers in the Zhengding area typically adopt a three-level control approach in their designs. The first level is negative pressure extraction, which creates an airflow from the outside to the inside of the toilet cubicle to prevent odors from escaping. The second level is filtration treatment, where the extracted gas passes through activated carbon or biological filters for adsorption and decomposition. The third level is source inhibition, where deodorizing microbial agents or chemical neutralizers are pre-placed in the collection containers to reduce the production of odor molecules at the generation stage. For occasions that require flushing, foam-sealing environmental-friendly toilets are also produced. These use a small amount of foaming liquid mixed with water to generate foam instead of a large amount of flushing water. The foam itself contains surfactants that can wrap the waste and block odors, while reducing the flushing water volume to one-tenth of that of traditional toilets.

Structure and Function

Its physical structure usually consists of a load-bearing module, a sanitation module, and an auxiliary module. The advantage of the modular design is that individual modules can be replaced or repaired separately in case of a malfunction. The waste storage system is the core functional unit, maintaining a relatively stable internal environment through physical isolation and chemical treatment. The ventilation system is more effective when using mechanical ventilation, with exhaust fans installed at the top to force out the internal air and introduce fresh external air.
