In general, except for spring water and well water (underground deep wells) that can be directly consumed, whether it is river water, lake water, stream water, snow water, rainwater, dew water, or water obtained through infiltration, filtration, and sedimentation, it is best to Disinfect before drinking. So how do you do disinfection? Methods as below:
The use of chlorite, bleach, can also act as a disinfectant. In the purified water, 3 drops or 4 drops of bleach per liter, and the turbidity of the water is doubled. Shake well and stand for 30 minutes. Just the taste of some bleach in the water, be careful not to drink the precipitated turbidity together.
If none of the above disinfecting drugs occurs, it is sensible to carry the vinegar that is used in picnics (white vinegar is also OK) and it is also possible to disinfect the water. Pour some vinegar in the purified water, stir well, and let it stand for 30 minutes before drinking. It's just the acidity of some vinegar in the water.
In the case where the altitude is not too high (above 3,000 meters above sea level) and there is a fire, boiling the water for 5 minutes is also a good way to disinfect the water.
If the water you are looking for is salt water, cook with pepper grass and water. This can not remove the original salty taste, but it can prevent abdominal pain, bloating, and diarrhea. If there is heavy metal salt or toxic minerals in the water, use thick tea and boiled water. Do not drink the last sediment.
Make a simple filter: dig a small hole in the bottom of the container filled with water, insert the root tube; spread a layer of small stones on the bottom of the container, then spread a layer of coarse sand, and then spread the sand, charcoal, towels Wait. In this way, the turbid water can be filtered into clean water and sterilized tablets can be used for drinking.
Take an empty plastic beverage bottle, cut the bottom, and use a single-hole plug with a catheter to close the bottle. Place the bottle upside down. Place layers of washed loose cotton, gauze, activated charcoal (charcoal), and quartz in the bottle. Sand, pebbles, etc., get a simple water purifier.
Explanation:
1 Pebbles, quartz sand should be washed clean, pebbles, quartz sand filter effect.
If there is no single-hole plug with a catheter in two homes, several small holes can be made in the cap to replace the single-hole plug with a catheter.
At present, there are several mature field emergency drinking water purifier devices.
1 pen-type water purifier in the field is very practical, shaped like a thick pen, built-in inorganic ceramic filter through the water it sterilized, non-toxic, odorless, no impurities, without boiling can be drunk, very light.
2 mobile emergency water purification equipment, integrated design with the trolley, easy to move and maintenance. The rivers, rivers, and lakes can be made into potable water in an instant, and the production and domestic water for islands, coastal water-scarce areas, ships, and oil fields can be widely used for barracks, exploration, geology, flood resistance, and disaster-resistance personnel. At the same time, self-provided generators drive the pump, no external power supply.
Features: stable water production, not easy to block and good water quality; water production capacity can be customized according to requirements;
Production: The production capacity is 0.2T/h, 0.5T/h, 1T/h, 2T/h, etc. It can also be designed and manufactured according to customer requirements.
Effluent: selectable water standards: drinking water GB5749-2005; bottled purified water GB17323-1997 etc...
3 Others such as: On-board water purification equipment or self-priming water pump Pu Qingshui pioneer commercial household water purifier
In addition, we must remind everyone that in the case of water shortages, it is necessary to arrange drinking water rationally and not to drink for a moment of thirst. Common sense in this area is reflected in many TV dramas and films. In addition, in the field work or adventure, drinking water should also pay attention to science. If you drink enough at a time, the body will excrete excess water after absorption, which will waste a lot of water in vain. If you drink water, drink only one or two at a time, and then slowly swallow in the mouth. After a while, when you feel thirsty, take a sip and slowly inhale. This way, you can make the body drink. The water is fully absorbed and it can solve the dryness of the tongue and throat.
