How do open-air ski athletes go to the toilet?
The toilet hides black technology without a drop of water
How do athletes go to the toilet in an open-air ski resort?
Will the water pipes freeze?
The answer is: there are mobile toilets on call at all times, and there is no need to flush at all!
The "high-tech" hidden in the toilet amazes the athletes.
This "water-free flush-free biological toilet" has been put into use in the National Stadium, the main media center, the National Speed Skating Stadium, the Shougang Grand Jumping Platform and the Yanqing Alpine Ski Resort.
"The venues for the Winter Olympics are very cold. The temperature of the outdoor venues is about minus 20 degrees Celsius. The water pipes are easily frozen, and cleaning and transporting excrement in the high mountains is also a big project. So we simply remove these obstacles and do not need to use the whole process. Water, no feces!" Tian Lan, chairman of Gansu Zhangye Lanbiao Biotechnology Co., Ltd., a research and development enterprise of water-free and flush-free smart ecological toilets, told reporters.
The shape of this toilet is similar to the mobile toilets in the streets and scenic spots, but if you look closely, you will find that there are no upper and lower water pipes in the toilet, and there is a "square" below the toilet.
How is the feces washed away?
"There is no need to flush the toilet after going to the toilet, but it is as clean and hygienic as flushing the toilet. This is the biggest feature of this smart ecological toilet." Tian Lan introduced that the reason for not flushing with water is that the toilet uses microbial degradation technology, which can achieve both The manure is "invisible", odorless and tasteless, and the toilet can be moved at will; only need to replace the biological bacteria once a year, and the waste can be turned into organic fertilizer.
When athletes go to the toilet, the excrement will enter the biological warehouse along the mechanical device inside the toilet. The biological warehouse is filled with a kind of efficient degrading microbial strains, which are specially cultivated for the components of the excrement. Excrement is effectively decomposed.
The excrement of 100 people is decomposed by the flora, and finally there is only the amount of one person left.
The degraded excrement will eventually become organic fertilizer and be transported away to realize resource reuse.
A special high-temperature treatment process is also designed in the biological warehouse, which can quickly heat up to more than 60 to 70 degrees, which can not only speed up the decomposition rate and improve the processing efficiency, but also kill pathogenic microorganisms and prevent the spread of pathogens.
For odor, a biological deodorant fungicide is designed and constructed, using biotransformation technology to achieve deodorization effect, so users can't smell a little odor.
Air conditioning is installed in the toilet for heating, and the toilet seat is also equipped with a heating function to make the toilet more comfortable.
At present, more than 300 such waterless and flush-free ecological toilet products have been used in many Winter Olympics venues, volunteer service areas, airports, main logistics and public areas.
Since July last year, this waterless and flush-free smart ecological toilet has been stationed one after another, and the reporters in the main media center were the first to experience it.
"There is also high technology hidden in the toilet!" Foreign reporters were amazed when they used the toilet without water.
