Talking about the pollution problem of drinking fountain
There are three main problems in drinking fountains. One is that the boiling temperature of water is insufficient. The maximum temperature of most drinking fountains is 95 degrees, the boiling temperature is 90 degrees, and the temperature of brewing tea is not enough. Second, it is repeated for warm water of drinking fountains. Heating, forming the so-called "thousands of boiling water", so that trace elements and minerals in the water accumulate to form insoluble particles; third, the inside of the water dispenser is difficult to clean, and it is easy to accumulate scale and bacteria.
"The drinking fountain that has solved the first problem has the boiling water dispenser of Xinhui City Tengfei Industrial Co., Ltd., the beautiful water diversion machine that has solved the second problem, the company that solves the third problem already has, but I forgot On which date the newspapers are, I am sorry. The three companies have applied for patents respectively, so other companies cannot produce their own technology. In addition, these patented water diverters are very expensive and basically do not want us to be used by the poor. â€
According to reports, in traditional household water dispensers, the heating of water is done by built-in hot biliary. According to Fang Shuguang, it is this kind of liner that makes the traditional water dispenser harm:
Long-cooking produces “thousands of boiling waterâ€: After repeated heating of the drinking water in the hot bile, it will form “thousands of boiling waterâ€. This kind of water contains harmful substances such as heavy metals and arsenic compounds. Long-term drinking can harm gastrointestinal health.
Scale becomes an “additiveâ€: According to a report issued by the National Environmental Testing Department, if the traditional water dispenser liner is not cleaned for more than 3 months, it will breed a large number of bacteria, residues and even red worms, which will adhere to the inner wall of the hot bladder and become a toxic “additiveâ€. ". When these substances enter the body, they cause pathological changes in the digestive, nervous, urinary and hematopoietic systems.
Hot spleen manufactures "nitrate": hot urethane is mostly made of stainless steel and aluminum shell. Tests show that under long-time heating, the nitrite content of iron, aluminum and ammonium in water will increase significantly, while nitrite is people. A well-known carcinogen.
Household appliances "power consumption king": Take 1 liter of hot water as an example. In the state of not shutting down, the traditional household water dispenser with a power of 0.5 kW consumes 1.8 kWh per day, precisely because of its "burning stop". "Working principle, invisible caused more than 90% of energy waste.
In order to reveal the problem more intuitively, Fang Shuguang “opened the water dispenser†collected from a Beijing resident's family at the press conference. It is clear that the rust and thick scale on the inner wall of the hot bile. According to Fang Shuguang, at present, more than 99% of household water dispensers in China use this kind of "hot and sturdy products" that are flawed in design and construction.
