According to the World Health Organization (WHO), 80% of the world's diseases and 50% of child deaths are related to safe drinking water;A quarter of China's population is drinking water that does not meet sanitary standards。

In 2016, the Ministry of Water Resources released the Monthly Report on Groundwater Dynamics, showing that groundwater quality is generally "poor" across the country, and more than 80% of groundwater is threatened by pollution。Earlier statistics from the Ministry of Land and Resources showed that more than 400 of the country's 657 cities rely on groundwater as a source of drinking water。Nationwide, nearly 70 percent of the population drinks groundwater。

The China Water Safety Public Welfare Foundation of the China Social Relief Foundation has conducted sampling tests on the drinking water quality of residents in 29 large and medium-sized cities across the country, and the results show that 14 of the 29 cities have one or more unqualified indicators, accounting for about 48% of the total number of cities sampled。The main problems are that the residual chlorine content of water sample is not up to standard, the turbidity is over standard, the fluoride content is low, and the total number of bacteria is over standard。

Water pollution can be divided into biological pollution and abiotic pollution, polluted water sources contain a lot of bacteria, residual chlorine, heavy metals, volatile substances, rust, sediment...

How to drink clean water?

Faced with the current situation of water pollution, how should we stay away from pollution and disease and drink clean water?

Option one: Bottled water

Disadvantages: high price, frequent replacement, secondary pollution

Presumably some people will choose to drink bottled water,But at market value,The price of a good quality barrel of water is about 15 yuan,A family needs about 6-10 barrels of water a month,Let's say 100 yuan a month,That's $1,200 a year,That's 2,400 yuan for two years,Three years is 3600 yuan...And whether it's production,Or consumption link,Bottled water is prone to secondary contamination。

Option two: Bottled water

Disadvantages: expensive, secondary pollution

Bottled water is extremely costly and not suitable for daily household use。Bottled water is listed as a daily water for a small number of wealthy families, but this method is too expensive and may not be as effective as water purifiers。The price of a bottle of water is calculated at 2 yuan, a person a day at least 5 bottles of water, a year down to 3650 yuan, a family of three a year will be 10,950 yuan...If you are rich, feel free!

Option 3: Water purifier

Advantages: good water quality, strong purification capacity

The layers of filtration of the water purifier can remove all pollutants from the water。首先,Suspended matter in water, rust and various fine pollutants, colloids, hair and other small impurities,Remove residual chlorine, color, odor;secondly,Remove water chemical pollution pesticides, fertilizers, odors, etc,Removal of heavy metals such as lead, mercury, cadmium, nickel, arsenic, aluminum, chromium, calcium and magnesium;finally,The bacteria, viruses, ultramicroparticles, macromolecular organic matter in the water body are completely removed。

According to incomplete statistics, the filter element of a water purifier can intercept about 3600 mg of rust, 98000 mg of organic matter, 500 mg of sediment impurities, 4 mg of lead and so on。If these organic and heavy metal ions drink into the body, gradually accumulate every year, you can imagine how much harm to the human body will be。

Generally, the price of an efficient reverse osmosis water purifier is 3000-5000 yuan, and the service life of the water purifier is long, the water production cost is low, and is not limited by time, that is, it is convenient and cost-effective。As long as according to the water quality, the filter element can be replaced regularly。
