What are Vacuum Toilets?

The vacuum toilet is to create a vacuum for the entire system. The system must have an isolation valve to isolate the system from the toilet. When the toilet is flushed, this valve is opened and the pressure in the toilet is taken away from the toilet.

Vacuum toilet

The ordinary toilet flushes 6 liters of water at a time, and the vacuum toilet only needs 0.6 liters. It can also separate the urine and feces, and directly put the feces into the fertilizer plant to make organic fertilizer. The urine, bath water, and vegetable washing water will be collected The net flows into the "artificial small wetland" at the entrance of the house. After the nutrients in the water, such as nitrogen and phosphorus, are absorbed by the plants in the artificial wetland, the second type of water available for the landscape comes out.

This system must be equipped with a vacuum pump to create a vacuum in the entire system. Each system leading to the toilet must have an isolation valve to isolate it from the system. When the toilet is flushed, this valve is opened and the toilet is relied on the pressure difference from the atmospheric pressure. Take something away. The vacuum system is dependent

The core technology on which the vacuum toilet relies "Separation of source of domestic sewage, full circulation of water and nutrients, resource utilization, and decentralized ecological treatment demonstration project",

It was designed by the Chinese Academy of Sciences. Compared with the current small artificial wetlands in rural areas such as Hangzhou and Shaoxing, the average wetland area required by this system brought by the Chinese Academy of Sciences is only 1 square meter per person, which is 1/3 of the traditional one.

It takes about 10,000 yuan for a rural family to build this system, including the construction of a pipe network, a toilet, and a wetland. In the future, hospitals, restaurants, etc. can refer to this system construction. The completed system can be described as zero emissions.
