? In recent years, new scams have appeared in many rural areas, which are the so-called seven-day sales fairs (or trade fairs, etc.). For the first two to three days, there were lectures and small gifts. Talk about health and wellness, and use small gifts to stimulate students. Those who listen carefully will receive small gifts after class. Build popularity for later use. On the third day, it was said that it was a camel hair quilt worth 1970, and a deposit of 20 was paid in advance. On the fourth day, I bought it for 1950 and received a red envelope. Someone will buy it on the fourth day and the 1970 red envelope will be returned to you intact!

On the fifth day, I continued to promote and use electrolyzed water to say: Look at how serious the water pollution here is. Children, I will do whatever you want for your health! No matter how exaggerated they are to explain how good their water purifiers are, just pay a deposit in advance! If you buy a water purifier tomorrow, I will give you a big and small red envelope in return! During this period, a vacuum pot worth RMB 58 was sold for RMB 400! The sixth day was the top priority. For more than three hours in one morning, 70 or 80 people bought water purifiers.

It ended perfectly on the seventh day, with a big and small red envelope each, which contained the so-called gift card, a "camel hair quilt" and a "sandalwood jade" pendant... If you are a loyal fan*** For about RMB 2500, you can get the following gifts: plastic basin, electric comb, vegetable basket, aluminum basin, aluminum water ladle, induction cooker, vacuum pot, egg steamer, pressure cooker, camel down quilt, water purifier, sandalwood jade pendant, again great value Make a fortune. Generally these people will leave once they make money. The phone can't be reached. And these free products are often low-quality, three-no products that pose great safety risks after use.

Answer: Water is the source of life. If the family's economic conditions permit, it is recommended to install it. At present, water purifiers are very popular in households in large and medium-sized cities, so we often see seven or more people in the city. An 80-year-old man looks younger than a man in his 40s or 50s in the countryside.

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

?① ?Although there are relatively few rural industrial areas, annual crops (such as rice) To prevent and control pests and diseases, pesticides need to be sprayed multiple times. Some of the pesticides circulate with the water body and gradually penetrate into the groundwater over the years. In addition, the heavy use of chemical fertilizers leads to excessive heavy metals. Finally, they are pumped up by water pumps for drinking. If they are not purified, Finally, it is drunk into the body; over time, human organs slowly develop lesions or cancer. This is one of the reasons why more and more people in rural areas have been suffering from cancer in recent years.

② ? Substandard discharge of domestic sewage aggravates water pollution. For example, behind the streets, domestic sewage, garbage and feces are discharged directly into the river, causing the water to contain a variety of substances harmful to the human body. , as the water circulates and finally penetrates into the groundwater.

? ③ ?At the same time as the economy is developing rapidly, environmental pollution is becoming more and more serious. Substandard discharge of industrial water has also aggravated the pollution of water resources; according to statistics from the national environmental department, 82% of rivers in my country are affected by Different degrees of pollution; among my country's seven major river systems, more than half of the river sections are not suitable as drinking water sources; 78% of the river sections in urban waters are not suitable as 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.) harm the body, especially on the skin quality of teenagers and women;

? ⑤ ?Although tap water is basically used nowadays, after the tap water leaves the factory, it needs to go through a long water pipeline network, water towers, water tanks and other facilities, and is exposed to many pollutants, such as rust and scaling. , corrosion, heavy metal pollution, pipe network pollution, residual chlorine and other secondary pollution problems. For example, it is common for everyone to see red, yellow, or black water coming out of the faucet as soon as the water plant is shut down and the water is supplied again.

⑥ According to statistics from the World Health Organization: 80% of the world's diseases are caused by drinking contaminated water, and 50% of the world's child deaths are caused by drinking contaminated water.

In view of the above situation, in big cities, households with a little knowledge of water will adopt different water purification processes according to different uses; for example, using primary purification (such as whole house filtration system) for domestic water can prevent Washing machine, water heater shower nozzle is clogged, etc.).

Deep purification is used for drinking water, including ultrafiltration system or reverse osmosis system.

At present, water pollution breaks out frequently around the world, and freshwater resources are becoming increasingly scarce. When low-carbon and environmental protection have become the focus of people around the world, water purifiers, an environmentally friendly product that has been in the country for more than ten years, , and is increasingly understood and accepted by the people.
