I am hungry in the end of the natural disasters, I have space to fill up the supplies

Chapter 94 Filtration Devices
Qin Hao and Ma Dexiang went to work as usual.Su Mi also continues to paddy in her two greenhouses for growing vegetables in the courtyard.

Because the stream water was poured on the first day, the newly planted seeds tended to germinate, which made Su Mi dare not water directly with stream water the next day.

If watered continuously with stream water, the seeds will grow into miniature seedlings the next day.Such an incredible thing must not be allowed to happen in front of others, not even Qin Hao, Tiantian and Ma Dexiang.

Therefore, Su Mi then considered using tap water.However, after pouring tap water once, it was obvious that where the seed skins burst open, the green shoots that were originally full and green were greatly reduced in vitality.There is a tendency to wither.

It was only then that Su Mi immediately thought of the reason why there are no living plants in the base. I am afraid that it is not only the soil, but also the water quality.

The polluted water quality not only cannot allow the seeds to absorb and germinate, but also leads to the loss of vitality and even death of the seeds in a short period of time.

It cannot be watered directly with tap water, and it is too wasteful to use drinking water.No matter how much water there is in her space, there will be a day when she runs out of it.

It is indeed a waste of water with these.Is there any way to filter out harmful substances in tap water?Su Mi thought about going out to find a water purification device before, but the time period was tight, so she had to make one first to see if physical filtration would work.

There are buckets of purified water everywhere, and you can exchange two for one steamed bun in a shop.Su Mi cut off the water outlet of one of the buckets, and cut out a larger round mouth.

Cut off the bottom of the other bucket, and turn the bucket upside down with the water outlet facing down. First, tie two layers of fabric cut out of pure cotton short sleeves on the water outlet.

After fixing the two prepared barrels one by one, Su Mi began to worry about which filter material to use.The soil, fine sand and stones on the ground cannot be used. After all, the heavy rain has just passed, and the land is so polluted that it cannot be planted. Who knows if the fine sand and stones have been polluted.

So Su Mi set her target on the red brick in the space, so she chose a broken red brick and knocked it into more pieces, and put it aside for later use.

Her father once raised fish before his death. Su Mi knew that to simulate the water quality of fish in the natural ecological environment, the filter material needs not only coarsely filtered stones, but also natural fine sand to decompose harmful substances in the water. More delicate physical and chemical filtration is required to filter out harmful substances such as bacteria and parasites in the water.

But Su Mi thought about it for a long time and couldn't figure it out. Things from the outside world are temporarily unusable, so what about in the space?

Su Mi finally fixed her eyes on the black soil in the space.

The black soil is soft and full of nutrients. Most importantly, there is a thin aura belonging to the space in it, which can be used as the decomposition function of the sediment.

As for the other things, Su Mi didn't have any at hand, so she finally decided to use these two things to try the filtering effect first.

In the upside-down bucket, the bottom part near the water outlet was filled by Su Mi with a mixture of black soil and broken red bricks, and a layer of pure cotton cloth cut from clothes was laid on top, followed by a layer of red bricks A finely crushed powder.

Then, a layer of black soil, a layer of cloth, a layer of red brick and a layer of cloth filled the bucket halfway, and Su Mi used a larger piece of cotton cloth to cover and fix the water storage bucket above.

This layer of fixation is regarded as the first layer of physical filtering.

So Su Mi poured a large bucket of water to the patio and started experimenting.

In addition to the smell of bleach in the tap water in the bucket, there are many small substances in it.There are quite a few that can be seen with the naked eye, and there must be more that cannot be seen.

After the water is poured into the storage tank, it is filtered through the first layer of cotton cloth, leaving no obvious impurities on the cotton cloth.The water enters the water storage bucket and begins to soak through the filter material of the sumi pad layer by layer, and finally flows to the bottom water outlet, and then drips into the empty bucket below.

At the beginning, the filtering speed was not fast, but later, the dripping speed became faster and faster, and soon all the water stored in the filter bucket above was filtered out.

In the end, I got a bucket of water below. I don't know if there is any water that meets the watering standard.

So I took out a cluster of sprouted seedlings in the space, poured water on it and tried it.

After waiting for a few minutes, the seedlings did not show any decrease in vitality or other problems. Su Mi took a small bowl, poured some filtered water into it, and soaked the seedlings in the water.

Take it out 10 minutes later, no change at all.There is no state of reduced vitality and withering, and the seedlings are soaked, but the leaves are more erect and green and deeper.

"It seems to be a success. In this way, the filtered tap water can be directly used for watering."

Su Mi sniffed the filtered water, and there was no smell of bleach at all. It was clear and clean, and it should be fine for washing vegetables and clothes, but I don’t know if it can be used for daily drinking.

Apart from coming out for breakfast in the morning, Tian Tian stayed in the living room with his eyes on the second-grade elementary school textbook Qin Hao found for him, and assigned homework, so Tian Tian did not follow her today.

It's already noon when Su Mi finished these things, and it's time to eat.

There are still three big steamed buns left in the morning, each of which is very big, and one is very full.Su Mi felt that the steamed buns were too bland, so she found a bag of mustard and sausages in the space and ate them.

Tiantian was very happy about Su Mi's behavior of opening a small stove, and never mentioned it to Qin Hao and Ma Dexiang.Gradually, this became a little secret between him and Su Mi.

In the evening, Qin Hao still brought back prawns, and this time there was even an extra bream.

When Ma Dexiang came back, he was carrying a bag with a small handful of rice in it. "This is replaced by the white porridge in the morning and noon and the steamed buns in the work meal, and I directly pour it into the rice bag.

Alas, the food at home is still delicious. "

"Brother Hao, your cooking skills are comparable to mine, and the steamed buns in the morning are so delicious, why don't we make more food in the morning, so we can bring our own lunch.

The work meal is made with tap water, and I could barely eat two bites.

How can I swallow it now.And your stewed prawns are simply delicious. "

Qin Hao nodded, "There is still a lot of flour at home, which is enough for us to eat for a month. With rice, it can last for a long time."

But Qin Hao was not thinking about this issue at this time. "Su Mi, we have been spending so much, and we don't go out to search for supplies. With the income from my work with Lao Ma, we will definitely not be able to pay next month's rent.

Even in a small building, it may be difficult. "

At this time, if Qin Hao was told that several people were going to move to Tongpu, they would absolutely not accept it.After all, it is easy to go from simplicity to extravagance, but it is as difficult as going from luxury to frugality.

Su Mi smiled mysteriously, "Don't worry, you are responsible for the cooking and cleaning every day, and I can just leave the rent to me, don't worry."

　The second update is coming
　　It's the end of the month, clear up the tickets in everyone's hands and give them to me
