Chapter 35: Sudden water cut

After a month of calm, Chen Xin's life has not changed much during this month.

He wakes up from the phone alarm on time every day, just like he used to sleep

until he wakes up naturally.

The day is not visible in the refuge, and it is meaningless to rely on light

to judge day and night. In order to avoid ignoring the time of sleep, Chen Xin

reset the phone alarm.

Since he quit his job a few years ago to write a novel, this is the first time

that Chen Xin has turned his mobile phone alarm back on.

But returning to a regular schedule is also a brand new experience for Chen

Xin, at least he feels that his mental and physical conditions have improved a

lot.

Regular work and rest times naturally bring regular work and rest habits.

After waking up, brushing his teeth and washing his face, Chen Xin will tear

up a generation of self-heating food for breakfast, and while waiting for

self-heating food to heat up, he will take advantage of this time to do more

than a dozen Minutes of exercise, exercise.

Wait until the warm-up is over and the breakfast is already cooked. Eating at

this time will make people more appetite.

In the morning after eating, Chen Xin will first check the operation of

various equipment in the shelter, and fill up the generator.

After starting the generator to power the entire shelter, he will spend the

morning in the planting greenhouse.

Although we do not need to weed and remove insects, watering, fertilizing, and

soil loosening are still needed.

Needless to say, watering and soil loosening, although Chen Xin has not done

it before, but with the video data in the computer, he can still make the

difference and basically meet the requirements of planting.

Although these vegetables cannot be said to be very lush, they are basically

growing healthy and there is nothing wrong with them.

The only thing Chen Xin couldn't stand was fertilizing.

When Chen Xin moved into the shelter, he did not buy chemical fertilizers. The

soil in the planting greenhouse was obtained from the vegetable garden of a

nearby farmer's uncle. Of course, the soil quality is not a problem, and it is

the vegetable plot left by the farmer's uncle's family. He grows vegetables

for his own consumption, so he has never used fertilizers and pesticides.

However, when the farmer sold the soil to Chen Xin, he also reminded him that

if he wants to grow delicious vegetables, he must remember to fertilize.

The fertilization of the farmer's uncle is of course not chemical fertilizer,

but the legendary...farm manure.

This thing is simply to use the black water part of the refuge water cycle

system introduced before, the liquid obtained after fermentation, and the gas

produced during the fermentation process is the legendary biogas.

Under normal circumstances, a biogas digester is generally built in rural

areas. The waste of humans and animals, straw and other organic matter are

filled into the biogas digester, and methane is generated by the decomposition

of the biogas bacteria, which can be used for daily cooking, heating, lighting

and power generation.

is a very common facility in the rural areas of Yan Country. It was promoted

vigorously in the 1990s for the treatment of rural human and animal waste and

to improve rural living conditions.

The black water treatment system in the sewage treatment system installed by

Chen Xin also uses the same principle. It uses bacteria to decompose and

recover the organic matter in the black water to realize the recycling and

reuse of water resources. As for the gray water, it contains soap and washing

water. The residues of hair lotion and washing powder cannot be directly added

to the biogas digester, because these things will kill the decomposing

bacteria in the biogas digester.

Chen Xin also considered using biogas as energy in the refuge before, but

after calculating, he found that his excretion alone was not enough to meet

the gas production needs of a biogas digester, so he had to give up this idea

and did not use biogas. As an energy source.

But even if biogas energy is not used, biogas digesters can still be used as

an important sewage treatment method, which can effectively decompose the

organic matter in the sewage and accelerate the recycling of water resources.

Just the smell of the fermentation tank used for sewage treatment...

The smelly socks that haven't been washed for a month in the boys' dormitory

are compared with the fermentation tank that hasn't been opened for a month.

This is probably the difference between stinky tofu and canned herring.

That sourness...Chen Xin went in with his gas mask, but still almost all the

tears came down.

Fortunately, the sewage treatment tank is outside the container room, and Chen

Xin has turned on the forced ventilation after taking into account the smell

of this thing, so the smell will not permeate the entire shelter.

The recycled sewage that had been fermented for a month was packed into the

planting greenhouse by Chen Xin in plastic buckets prepared in advance, and

then poured into the soil one by one.

Although the taste of this thing is really sour and refreshing, it has to be

said that nature is a complete cycle. It is the organic matter that is

decomposed that can make plants thrive.

After fertilizing, it was watering. However, what surprised Chen Xin today was

that when he watered halfway, there was no water in the pipe.

This shocked Chen Xin. He hurried to check the water tank and sewage treatment

tank, and found that his water tank that could store three tons of fresh water

was empty. UU reading www.uukanshu.com and the sewage collected in the sewage

treatment tank was only half. Full state.

Looking at the empty water tank, Chen Xin couldn't understand why the water

vapor in the air was collected by the sewage treatment tank and the water

circulation system, and the water was still used up.

However, if there is no water, there is no water. Although there is still a

lot of drinking water for drinking, only two and a half boxes of purified

water are used, and there is still a lot of inventory, but the domestic water

and greenhouse water for planting have been exhausted. Up.

Now Chen Xin must find a way to replenish fresh water, otherwise he will fall

into a crisis of water shortage, or use stored drinking water to supplement

domestic water.

Using drinking water to supplement domestic water is the last choice made when

there is no other way, but Chen Xin would not do it when there are other

choices.

Without using drinking water to supplement domestic water, Chen Xin has only

two options.

First of all, Chen Xin can choose to take the risk to open the door of the

refuge and go out to find fresh water resources.

One month has passed. The fire caused by the meteorite impact should have been

extinguished with the gradual drop in temperature after the sky was covered by

dust over time. It should not be too dangerous to leave the refuge now.

And this in itself was one of Chen Xin’s original plans. One month after

entering the shelter, he opened the shelter and went out to install the

antenna of the shortwave radio station. At the same time, he could get in

touch with the companions of other survival groups. Several companions in the

city exchanged supplies.

At least Chen Xin can be sure that a companion in the city didn't plan to

plant a greenhouse. Bringing fresh vegetables in the past can exchange a lot

of things with her.

But there is a problem with this, and that is how Chen Xin should bring fresh

water back.
