Although the number of automatic water vending machines is gradually increasing, there are more and more questions and worries involving water vending machine users. The daily maintenance of water vending machines is uneven, and the regulatory vacuum caused by the current multi-sector cross-management has increased. Many people are worried about the water dispensers.

Body rust stained protective doors can open anyone

The reporter found out during the interviews with the water vending machines in multiple districts in the urban area that all the water outlet protection doors could be directly opened. Only water sales opportunities in individual communities were affixed with water quality monitoring records on the machines, and water quality records were recorded. The date and various detailed indicators, and more than half of the water dispensers are covered with dust due to the lack of routine maintenance services for full-time managers, and some are rusted.

“The water dispenser has been in the community for a year or two. Although it is advertised to be directly drinkable, it still feels unreasonable.” Ms. Zhao, who lives in a neighborhood near Dinghui Bridge in Haidian District, told reporters, “The water dispenser is At the entrance of the community, anyone can open the safety door of the water intake, which makes people feel that there is a safety hazard and is too easy to be polluted.”

Mr. Liu, who lived in a neighborhood near Fengtai Qingta, had decided to return the card after becoming a user of automatic water vending machine for a year and a half. “I saw the children in the community curiously opened the protective door of the outlet and even returned it several times. Touching the water outlet by hand touched my mind, and I rarely saw the worker's maintenance of the machine. After more than a year of use, the water dispenser was rusted from the outer body to the outlet. It is really not afraid to drink again."

Corporate water samples never undergo professional testing

According to sales companies, the water quality of a water dispenser is about the same as that of pure water, and 3 tons of tap water can be filtered to produce 1 ton of such oxygen water. But is the water quality of the water dispenser really safe?

The reporter's investigation found that even if the manufacturer can guarantee that the water purifier is qualified at the factory, it is impossible for consumers to know whether the water purifier is regularly inspected or replaced after use. It is understood that water dispenser companies generally use a TDS detection pen for water quality testing. The health management department conducts sampling inspections every year at the operating units, at least twice a year, and during special sampling inspections in the summer, mainly depending on the environment in which the equipment is used, the senses of the water, and whether or not to regularly replace filter cartridges. If necessary, water samples are randomly selected for water quality. Testing.

Liu Wenjun, a professor at the Institute of Drinking Water Safety at Tsinghua University, told reporters that TDS test pens are widely used in the direct detection and determination of pure water filter effect. The higher the TDS value, the more impurities contained in the water. “But for water quality, the detection pen test It is the most insignificant indicator.” Liu Wenjun believes that indicators such as the total number of colonies, coliform bacteria, and turbidity are the criteria for whether the water quality of the water dispenser can be used for direct drinking, but these TDS detection pens cannot be measured at all and only enter the profession. The laboratory can test it out.

However, the reporter asked a number of professional water quality testing agencies, and never had a water dispenser company take a water sample to a laboratory for professional testing.

There is secondary pollution in the water dispenser

“There are many hidden dangers in the safety of the community water dispensers. In the case of unfavorable supervision and maintenance, the “pure water” for drinking water vending machines is not as good as tap water at home.” An industry expert who has been working in the water industry has been accepting This was the case during the media interview.

The relevant person in charge of the Beijing Municipal Health Supervision Office told the reporter that according to the current statistics, nearly 5,000 units of automatic water-sale machines registered in the city were registered, but at the same time, a considerable number of products were not filed, and the health management department had no way of grasping the specific data and their Hygiene Situation. As to whether the automatic water vending machine is a regular product, the public can judge whether there is a sanitation permit approval number on the body of the water vending machine. In addition, the equipment of the regular water dispenser will display the equipment inspection records, such as the time and value of the cleaning equipment and the replacement of the filter element.

However, even if the automatic water vending machine is a regular product of a regular manufacturer, because most of the machines are installed outdoors, the outlets of many machines are exposed to the air for a long period of time. In particular, the equipment lacks effective maintenance. Once a failure occurs, timely treatment will certainly affect the quality of water. . If the water dispenser is closer to the garbage recycling station, it will be more likely to cause pollution.

“The rusting of the fuselage, the inability to close the guard door, the lack of special care, and the free-flowing water outlets, which may contaminate the water in the water dispenser,” said Liu Wenjun, professor at the Institute of Drinking Water Safety at Tsinghua University, who stated that tap water quality in Beijing Well, although the automatic water dispenser uses tap water as raw water, it is susceptible to secondary pollution during the production process and is not recommended for direct drinking by the public.
