0351 Simple Filtration Device

Tear live chickens, drink live blood, and stain the whole body with blood.

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

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

"Tearing a chicken alive is a training of courage. Drinking raw blood and eating live chickens are compulsory training subjects for field survival, and under the condition that fire is not allowed, physical strength can be quickly replenished. Wang Liang said.

The duty of a soldier is to train hard in the ability to kill the enemy, and 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 previously written a number of related academic papers, such as "Investigation and Research Report on Stressful Life Events and Their Mental Health Level of Military Training Officers and Soldiers", "Characteristics of Military Mental Health and Related Factors under Military Stress Conditions", and "Psychological Training of Scouts......

It can be said that Wang Liang has made great achievements in this research.

Soon, when it was time for lunch, the team 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 get water, light a fire, and cook.

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

Wang Liang first paid attention to the officers and soldiers' water collection operations.

The environment in the wild is very complex, and the water cannot be drunk casually.

Those who have served as soldiers, especially those who have fought in wars like Wang Liang, have naturally formed their own set of judgment standards.

The officers and men were busy making a simple filter based on local materials, and Wang Liang also made some summaries based on his many years of front-line combat experience: "The water that can be drunk must be living water, that is, flowing water, there is a place of origin, there is a channel to flow out, and basically this kind of water can be drunk." ”

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

"The water on the rocks is also not drinkable, because the rocks do not have a strong filtration and purification effect like the soil, and any dirt will be retained when it comes in. And there are a lot of bacteria in it, so water that is drunk on the soil is preferred. ”

"If there are obvious plankton in the water, you can't drink it, because the water is basically full of eggs, and drinking it will cause problems."

Wang Liang said, and the officers and soldiers listened and operated, which was quite comfortable.

It's a real treat compared to the physical demands of training.

The process of collecting the material is very simple, sand, gravel and charcoal are enough.

Sand and gravel are ready-made, charcoal needs to be made of wood to make a fire, and then let it be fully burned and then extinguished with soil and ash, and charcoal powder can be obtained by crushing the charred wood pieces with stones or sticks.

According to the assessment requirements, lighters, matches and other fire sources are prohibited.

The efficiency of drilling wood for fire is very low, what should I do?

I saw a sergeant directly take out the battery in the tactical flashlight, use cigarette tin foil to short-circuit the positive and negative poles, and instantly discharge and ignite the prepared dead branches.

Wang Liang nodded with great satisfaction, not dogmatic or rigid, scouts just want to be open-minded and eclectic.

In this way, we can adapt to the complex and changing environment and accomplish seemingly impossible tasks.

Use a dagger to cut the empty mineral water bottle from a third of the way and make a hole in 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-layer filtration.

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

Sand is a material that filters most of the impurities in the water.

"Put a little more, the sand layer 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 there was a soldier who put too little sand, obviously it was the first time to operate, Wang Liang couldn't help but remind.

On paper, I finally feel shallow, and I never know that I have to do it.

No matter how well you learn the daily theoretical lessons, you still can't detach them 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 it can flow through charcoal powder, sand, gravel layer, gauze.

When the water comes out of the bottom, use a clean cup to catch the water.

"The denser the gauze at the bottom of the water filtration process, 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 is clear or odorless. Wang Liang instructed.

These things, in Wang Liang's opinion, are simply fur.

Rainforests, deserts, Gobi, grasslands, temperate, tropical, and cold zones, it can be said that Wang Liang has fought in various environments.

After all, a simple water filter is just one way to get water.

Seeing this, Wang Liang really couldn't help but 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, taking water from plants, collecting dew, taking water through the transpiration of plants, desalination, homemade solar distillers and urine. ”

The scouts had long known that there was such an untitled chief training with them, and when they heard that the chief was going to give a lecture, they all gathered around.

"Let's start by talking about how to find surface water. I have three methods here, topography, plant growth, and animal and insect activity. Wang Liang didn't talk nonsense, and went straight to dry goods.

I took out all the tricks I had in Vietnam back then.

"The most preferred choice for water in the wild is flowing living water, which can be drunk directly and is relatively easy to find. We can listen to the sounds, with the help of the auditory organs, whether there is the sound of mountain streams or waterfalls at the foot of the mountain, mountain streams, cliffs, basins, valley bottoms, etc., if we can hear these sounds, it means that we are not far from the place where there is a water source. The acuity of the auditory organs needs to be trained, and this is usually done in this way......"

At this point, I saw that some soldiers had already taken out the pen and paper they had brought with them and began to take notes.

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

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

"Places where cattails, salix, lotus, goldenrod and other plants grow generally have a high water level and good water quality; There is also groundwater in places where plants such as grey cabbage, penny, and sariwan grow, but the water quality is usually not good, with a bitter and astringent taste, and even rust. ”
