In the end, everyone approved Zhang Wolf's proposal to build a drainage and sewage system. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Just like Zhang Wolf said, who wants to live in an environment where sewage flows, there was no way before, but now that the village is repaired so well, how to make the sewage flow is a little too sorry for everyone's hard work during this time.

Especially there is no need for the village to contribute, just to make some effort, and the most important thing for the people is strength.

In each village, it should be said that a clan went back to prepare things and organize people to hold sacrificial ceremonies.

Such a grand sacrificial activity is naturally inseparable from the nine old men, who organize clan sacrifices every year, and they are familiar with the festival activities, and take the initiative to take over the work of organizing the festival.

The three construction sites are very busy, and there are people who are willing to share the work, and he is a hundred willing.

The sewerage system doesn't mean that an underground pipe is just the end of the job.

The most important thing is the collection and treatment of sewage, the main thing produced in the village is domestic sewage, and the domestic sewage treatment process in foreign countries has been quite mature, according to its core technology, it can be divided into two types: activated sludge method and biofilm method.

However, no matter what kind of treatment process, there is no one in China, and now the country has not even solved the problem of food and clothing, how can there be energy to study sewage treatment.

This means that in the countryside, Zhang Wolf has a high prestige, and he doesn't have to pay for it himself, so everyone will be tossed by him.

If Zhang Wolf dares to propose the construction of a sewage treatment system in the city, he will not only be sprayed by people at the same level! It is estimated that he will also be interviewed by the leaders.

No matter what source the money is obtained, it is necessary to focus on more important things first.

In China, sewage treatment did not attract the attention of the state until the nineties!

It wasn't until the river turned smelly and black that I learned the importance of sewage treatment.

Just like this big mountain, it is barren and bald, and it is only when I think of planting trees and reforestation.

Zhang Wolf came from the afterlife, and he would never allow the Heishui River to turn black and stinky!

After some discussion with Hans, we finally chose the first, second and third level sewage treatment processes that are currently popular in the world.

The primary treatment process is to set up a fence at the entrance of the sewage treatment facility, mainly to use physical methods to intercept large floating objects, so as to reduce the load of the subsequent treatment structure and enable it to operate normally.

The secondary treatment process mainly removes organic substances in the colloidal and solubilized state of sewage, and usually adopts biological treatment method. Primary and secondary treatment processes are conventional treatment methods.

The tertiary treatment process is used to further treat hard-to-degrade organic matter, soluble inorganic matter such as phosphorus and nitrogen, which can lead to oxidation of the water body after the primary and secondary process treatment.

The result is grey water that can be used for irrigation.

In addition, a large amount of biogas can be collected in this tertiary treatment process.

Biogas is a good thing, as it can be used to make a fire for cooking, as well as for heating and lighting.

Biogas liquid is also a good thing and a good agricultural fertilizer.

Through the faith channel on the jade talisman, Zhang Wolf sent the purchase information to Ye Xiaoxian, asking him to purchase the sewage treatment system and biogas tank.

This is the latest communication method researched by Zhang Wolf, which is much easier to use than the mobile phones of later generations.

And the secrecy effect is good, there is absolutely no need to worry about eavesdropping.

…………

Several old men quickly prepared the three sacrifices and other offerings, and the sacrificial words were also written.

The tablets of the father-in-law and mother-in-law of the land were invited out and placed under the big locust tree, and more than 5,000 people in the village, including primary school students, all participated in the ceremony.

Cultivating believers should start with the baby.

Light incense and kowtow, then recite the sacrificial words, and then the kowtow ceremony is completed.

Zhang Wolf pretended to put the blueprints designed by Hans in front of his tablet, and made a muffled thunder in the air.

With a smile, he said to everyone: "Okay! The father-in-law of the land has already responded! Everyone go back! Disperse! Do whatever you have to do!"

He is in a good mood now, and after removing the incense consumed in the underground cave, there is still a lot left, which is really profitable.

Zhang Wolf took Hans and the people of the village committee to the pig farm. Originally, the pig farm was built according to the stock of 5,000 heads, and the area was very large, and it could be used as a sewage treatment plant with a little modification.

Moreover, the terrain of the pig farm is more than ten meters lower than that of the village, and it is used as a sewage treatment plant, and even the water pump is saved.

When they arrived at the pig farm, Zhang Wolf asked the excavator to be called.

"Dig in from here!" said Zhang Wolf, pointing to a cliff in the wild boar factory.

"Okay, Uncle Wolf, get out of the way!"

The second stunned agreed, climbed on the excavator, and began to dig at the position of Zhang Wolf's finger.

After digging a few times, the second stunned stopped, turned off the fire and ran out of the car, "Uncle Wolf, dig a cave!"

"Cave?" The people of the village committee and the old people who were idle and had nothing to watch the excitement were stunned.

How could there be a cave in this place, they were explored when the pig farm was built.

Although there were no professional exploration machines in later generations, as a family of craftsmen, they had their own methods of soil.

When the dust cleared, Zhang Wolf pretended to stand at the entrance of the cave and looked inside, there was a black hole inside.

"Go! Get some torches!"

After a while, the pine resin torches were delivered.

Zhang Wolf held a torch, "Mr. Hans, let's go in and have a look?

Hans didn't speak, but asked for a torch and took the lead.

Zhang Wolf and the third uncle and the fourth uncle also followed into the cave.

The cave is very wide, and there is no problem with running cars.

After walking more than a mile inside, the third uncle suddenly exclaimed, "Wait! There is a fork in the road here!"

Others also spotted the fork in the road, "There's that too!"

Hans, who was at the front, screamed, "Look! What is that?"

Everyone stepped forward and shone it with torches.

The fourth master looked at it for a while before saying, "Here...... This should be the root of the big locust tree!"

Zhang Wolf stood silently beside him and did not speak.

Let them discover the secrets of this cave on their own.

Several people explored the cave for a long time before they came out.

As soon as Hans came out of the cave, he began to draw on the ground.

It's really embarrassing for him, and once he went in, he memorized the various forks in the road.

When the map was drawn, Hans grew his mouth, "The Three Qing Dao Ancestors are on top! This is really amazing! There is actually a Bagua Array underground!"

The people of the village looked at the simple map drawn by Hans and were speechless.

They have read the plan of the new village drawn by Zhang Wolf no less than ten times, and now combined with Hans's sketch map, they found that this underground karst cave actually coincided with Zhang Wolf's plan map.

Hans stared at the sketches on the ground and shouted excitedly, "Locke, Sid, go get the instruments, let's measure again!"

"Mr. Hans, let's take another test in the afternoon! it's time for lunch!" said Zhang Wolf.
