? In recent years, many new scams have appeared in rural areas, that is, the so-called seven-day sales meeting (or trade fair). ). I have been giving lectures and giving small gifts for the first 123 days. Talking about health, health preservation and small gift stimulation. Anyone who listens carefully can receive a small gift after class. Cultivate popularity for later use. On the third day, it was said that it was a camel quilt worth 1970, and the deposit was 20 in advance. I bought it on the fourth day 1950, and then gave a red envelope. On the fourth day, someone bought it, and then 1970 red envelope was returned to you intact!

On the fifth day, I continued to publicize and said with electrolyzed water, "Son, you see how serious the water pollution is here. I think more about your health!" " ! Exaggerated description of how good their water purifier is, pay in advance! Tomorrow you buy a water purifier, I will give you a big red envelope and a small red envelope! In the meantime, there is a vacuum cooker worth 58 yuan 400 yuan! The sixth day is the most important. More than three hours a morning, seventy or eighty people buy water purifiers.

The seventh day ended perfectly, with red envelopes of different sizes, so-called gift cards, "camel quilt" and "sandalwood jade" pendant ... If it is loyal powder, you can get the following gifts: plastic basin, electric comb, vegetable washing rack, aluminum basin, aluminum ladle, induction cooker, vacuum furnace, egg steamer, pressure cooker and so on. Usually these people make money and leave. The phone is disconnected. However, these donated products are often inferior three-no products, which have great security risks after use.

A: Water is the source of life. If family economic conditions permit, it is recommended to install. At present, water purifiers are very popular in large and medium-sized cities, so we often see that the elderly in cities are younger than those in rural areas.

As for why a water purifier is needed, I will share with you the following reasons:

? ① ? Although there are few industrial areas in rural areas, crops (such as rice) should be sprayed with pesticides many times every year to prevent pests and diseases. Some pesticides gradually penetrate into groundwater with the circulation of water for many years. Due to the large use of chemical fertilizers, heavy metals exceed the standard, and are finally pumped up by pumps for drinking. If they are not purified, they are finally drunk into the body. Over time, human organs gradually become diseased or cancerous, which is one of the reasons why there are more and more people suffering from cancer in rural areas in recent years.

② ? Excessive discharge of domestic sewage aggravates water pollution. For example, behind the street, domestic sewage, garbage and feces are directly discharged into the river, which makes the water contain a variety of substances harmful to the human body and eventually seep into the groundwater with the circulation of the water body.

? ③ ? With the rapid development of economy, environmental pollution is becoming more and more serious, and the unqualified discharge of industrial water also intensifies the pollution of water resources; According to the statistics of the national environmental department, 82% of rivers in China are polluted to varying degrees; More than half of China's seven major water systems are not suitable as drinking water sources; 78% of urban waters are not suitable for cooperative drinking water sources; About 50% of urban groundwater is polluted.

? ④ ? Toxic and harmful substances in water (such as heavy metals, impurities and bacteria, radioactive substances and fluorescent substances, etc.). ) harmful to the body, especially to the skin of teenagers and women;

? ⑤ ? Although tap water is basically used now, after leaving the factory, tap water needs to pass through a long water pipe network, water tower, water tank and other facilities and come into contact with many pollutants, such as rust, scaling, corrosion, heavy metal pollution, pipe network pollution, residual chlorine and other secondary pollution problems. For example, as we all know, as long as the water plant stops supplying water, the faucet will produce red, yellow and black water.

⑥ ? According to the statistics of the World Health Organization, 80% of diseases in the world are caused by drinking polluted water, and 50% of children's deaths in the world are caused by drinking polluted water.

In view of the above situation, in big cities, families who know a little about water will adopt different water purification processes according to different uses; For example, primary purification is used for domestic water (for example, the whole house filtration system can prevent the shower heads of washing machines and water heaters from clogging, etc.). ).

Drinking water is deeply purified, including ultrafiltration system or reverse osmosis system.

At present, water pollution erupts frequently all over the world, and fresh water resources are increasingly scarce. When low-carbon and environmental protection have become the focus of people all over the world, water purifiers, which have a history of more than ten years in China, are increasingly understood and accepted by ordinary people.
