Chapter 349 Simple Filtration Device

0351 Simple filter device

Raw chickens were torn, raw drinks were used to activate blood, and the blood stained the whole body.

This kind of scene is obviously not suitable for live broadcast, the picture is too bloody, Wang Liang thinks that if it is broadcast live, it will definitely be reviewed by the administrator.

Obviously, this kind of picture is not suitable for many people to watch.

"Tearing live chickens is a training of courage. Drinking raw to invigorate blood and eating raw chickens are compulsory training subjects for survival in field battles. Under conditions where fires are not allowed, you can quickly replenish your physical strength." Wang Liang said.

The responsibility of a soldier is to train hard to kill the enemy. All training is to be able to kill the enemy.

It is the duty of a soldier to kill the enemy at all costs and by all means.

Wang Liang has written many related academic papers before, such as "Investigation and Research Report on Stressful Life Events and Mental Health Levels of Military Training Officers and Soldiers", "Soldiers' Mental Health Characteristics and Related Factors under Military Stress Conditions", "Reconnaissance Mental Training of Soldiers.
It can be said that Wang Liang has made a lot of achievements in this area of ​​research.

Soon, when it was lunch time, all the trainees arrived at the rest point with the old army, and all the trainees immediately started field survival training, looking for various convenient equipment on the spot to fetch water, light a fire, and cook.

As a consultant, Wang Liang followed up the whole process and quantitatively recorded the actions of the officers and soldiers.

The first thing Wang Liang paid attention to was the water fetching actions of officers and soldiers.

The environment in the wild is very complicated, so naturally you can't drink water casually.

Those who have served in the army, especially those like Wang Liang, naturally formed their own set of judgment standards.

The officers and soldiers were busy making a simple filter with local materials. Wang Liang also made some conclusions based on his years of front-line combat experience: "Drinkable water must be running water, that is, flowing water. There is a place of origin. There are channels to flow out, and basically this kind of water can be drunk.”

"There is moss in the water, and the moss covers the water, so the water is undrinkable."

"The water on the rocks can't be drunk directly, because the rocks don't have a strong filtering and purification effect like the soil, and it will keep any dirt that comes in. And there are many bacteria in it, so drinking the water on the soil is preferred. "

"Water with obvious plankton can't be drunk, because the water is basically full of eggs, and it will cause problems if you drink it."

As Wang Liang spoke, the officers and soldiers were listening and operating, which was quite pleasant.

This is really a pleasure compared to those trainings that consume physical energy.

The process of collecting materials is very simple. Sand, gravel and charcoal are enough.

Sand and gravel are readily available. Charcoal needs to be fired with wood, and then put out with soil and ash after it is fully burned. Charcoal powder can be obtained by crushing the charred pieces of wood with stones or sticks.

According to the assessment requirements, lighters, matches and other ignition sources are prohibited from being carried.

The efficiency of drilling wood to make fire is very low, what should we do?

A sergeant directly took out the battery in the tactical flashlight, shorted the positive and negative poles with cigarette tin foil, and the instant discharge ignited the prepared dead branches.

Wang Liang nodded very satisfied, not dogmatic or rigid, scouts just want to be open-minded and eclectic.

Only in this way can we adapt to complex and changeable environments and complete seemingly impossible tasks.

Cut the empty mineral water bottle from one-third with a dagger, and open a hole at the bottom.

Then wrap the bottom of the cut mineral water bottle with a piece of gauze, and put a plastic cup under the gauze to make a simple funnel.

Then spread the filter material into the mineral water bottle.

The first layer is gauze, the second layer is gravel, the third layer is fine sand, the fourth layer is charcoal, and the fifth layer is gauze.

Five layers of filtration.

The purpose of the gravel layer is to prevent the sand from flowing out to the point where the mineral water flows.

Sand is a material that can filter out most impurities in water.

"Put more, the layer of sand needs to be four to five centimeters thick to filter effectively, so don't put too little. Otherwise, the effect will be achieved." Seeing that a soldier put too little sand, it was obviously the first One operation, Wang Liang couldn't help reminding.

The end of the paper is so shallow that I know that this matter must be carried out.

No matter how good the daily theoretical lessons are, it is still not enough to be divorced from practice.

Finally, spread homemade charcoal powder, so that a simple adsorption device is completed.

Pour the sewage from the top of the container so that the sewage can flow through the charcoal powder, sand, layer of gravel, gauze.

Use a clean cup to catch the water when it runs out of the bottom.

"During the water filtration process, the denser the gauze at the bottom, the better the filtration effect. The water filtered out for the first time may not be very clear, and it can be filtered several times until the water becomes clear or has no peculiar smell." Wang Liang guide way.

These things, in Wang Liang's view, are simply superficial.

Rainforest, desert Gobi, grassland, temperate zone, tropics, frigid zone, it can be said that Wang Liang has fought in various environments.

Going through a simple water filter is only one way to get water after all.

Seeing this, Wang Liang couldn't help but want to teach these young scouts a few tricks.

Wang Liang opened his mouth and said: "Finding water in the wild is nothing more than surface water, getting water from plants, collecting dew, getting water through transpiration of plants, desalination of sea water, self-made solar stills, and urine."

The scouts had known for a long time that such an untitled chief was training with them, and when they heard that the chief was going to give a lecture, they all surrounded him.

"Let's talk about how to find surface water first. I have three methods here, terrain, plant growth, and animal and insect activities." Wang Liang didn't talk nonsense, and went straight to the dry goods.

Take out all the tricks you used in Vietnam back then.

"The most preferred choice for getting water in the wild is running water. Running water can be drunk directly, and it is relatively easy to find. We can listen to the sound and use our auditory organs to find out whether there are mountain streams or The sound of the waterfall, if you can hear these sounds, it means that we are not far from the water source. The sensitivity of the auditory organs needs to be trained, and this is usually the way to train.”

Speaking of this, I saw that some soldiers had already taken out the pen and paper they carried with them and started to record.

Obviously, they didn't have much contact with these things taught by Wang Liang before.

After talking about how to train the auditory organs, Wang Liang continued: "Then let's introduce how to find surface water through the growth of plants."

"Places where cattails, salix, Malian, and yellow flowers grow generally have a relatively high water level and good water quality; places where plants such as gray cabbage, poncho, and saliva grow also have groundwater, but usually the water quality is not good. Bitter and astringent, even rusty."
