McCurle played with a series of three palms.

In the middle, a palm comes out, and a ten-kilometer mainstream section appears.

Based on this, then the left side is the left, the right side is the same, and the two palms are sent out one after the other.

On the right, the right bank of the Han River, which is on par with the ten-kilometer river, changes the sky in an instant!

The biggest change is that some of the muddy water that used to flow there has become extremely clear and you can see the bottom.

On the left, the original disorderly barren mountains and wilderness have become uniform.

There was originally a river in this area, called the Heishui River, and the reason for this is not clear, but the flowing water in it is black and turbid.

Such river water is absolutely not allowed to be stored in the newly built water conservancy system.

Not allowing zài is just an attitude, and so on is more of a principled rule, not a reality.

The measures and countermeasures are enough to witness the pragmatic style of Mai Ke, Gu Jizhi and Zhen Jin.

Of course, Yang Gao, as the direct leader who is specifically responsible, has also made great efforts to investigate.

Although this Heishui River is not the mainstream, it is not even related to the main stream of the newly opened river, but runs parallel to the main river, and also flows from west to east.

But because it is located in the lower basin of an artificial river, it is also included in the new overall system.

From the Jialing River to the Han River, including the newly opened river channels, including the renovated Han River channels, including all the upstream tributaries, that is, the tributaries on the north bank of the Han River, the end points of these tributaries are all flowing into the Han River.

It also includes all the tributaries of the lower reaches of the Han River, all of which have the Han River at their source, and they all flow into the Yangtze River basin along the south bank of the Han River basin after flowing out of the Han River.

In addition to the upstream and downstream tributaries, there are also those rivers on both sides of the Han River, such as the Heishui River, these countless regional rivers, which were originally self-sufficient and self-sufficient, are now unified into the new water conservancy system.

This new water conservancy system, because it connects the Jialing River and the Han River, and the Jialing River is the upper reaches of the Yangtze River, so it is in nature a combination of the four major water systems, the Jianghuai River and the Han River.

Therefore, Mai Ke decided to give it a name, called "Jiahan Confluence", or "Jiahan" for short.

In the Jiahan treatment plan, the first measure to deal with a self-contained river such as the Heishui River is to adopt a conditional release strategy according to its original water quality.

Conditional release means that only water sources that meet the water quality standards of the whole system will be allowed to enter the entire circulation system.

The aim is to prevent new water sources from being added and to reduce the quality of the water flow already in the system.

This is the principle of strict control of water inlet channels that Maike adheres to.

The black turbidity of the water quality in the Heishui River absolutely does not meet the substantive requirements of the system, and all the first measures are taken first, and the entire Heishui River is restricted, and access to the water storage lake is prepared first.

The water is stored in it for a period of time to extract the contaminating substances and improve the quality of the water before the restrictions are lifted.

The re-released water meets the water quality requirements of the Garland system.

While improving the water quality in the lake, Maike has taken drastic measures to address the root causes of the pollution.

If it is the pollution caused by the natural material environment, then control those material environments.

For example, the black color of the Heishui River, after investigation, it was found that the river water passed through a section of the coal mining area, and the flowing water passed through the natural black coal seam all day long, and the fine coal dust came out with the water, which was not black and impossible.

In addition to this, there is also artificial pollution.

Presumably, this kind of coal has no other use in the local area, and it can even be used for heating and cooking, and no one has found it, but they found that it can be made into a dye, which is coal black indigo or something, so many families use a workshop and produce it on a small scale.

Don't look at the small scale of production, but the pollution caused is very consequence.

Every home workshop is a source of pollution from afar.

Due to the lack of environmental awareness and the very backward refining process, they produce very few dyes, but the amount of pollution caused is huge, and they are simply workshops specializing in the production of pollution.

Faced with this situation, Mai Ke first made a detour of the river, avoiding the coal mining areas altogether.

Secondly, Maiko, in cooperation with the local population, completely stopped the family workshops that produced indigo dye.

The losses they suffered as a result were compensated by Maike tenfold and hundredfold.

If there is any meticulous work to be done later, it is undoubtedly the most efficient way to do things with money.

Of course, Maike deeply knows that this is just from the point of view of work efficiency, a phased summary, and it is indeed the case.

However, this is not a fundamental solution.

There are still a lot of things to do, and it is necessary for later people to do follow-up work.

Of course, the main thing is to change people's lives, and these will be followed by Gavin and Luther.

After some operations by Mai Ke, the Heishui River became the Baishui River.

Its riverbed and water are completely renewed, and no pollution has entered it.

And the source of its water intake, Mai Ke has also figured out, is the Jialing River.

The water source of the Jialing River has been completely changed some time ago, and it has met the water quality standards of the Kingdom of Heaven.

That is Gu Jizhi's subordinate has a substantive standard comprehensive brigade is responsible, and it has the functions of inspection and supervision, of course, the criterion of these two daily work is the national unified standard they have formulated.

The existing water sources have been treated, and the contamination that has been separated has become useful once it has been separated.

Don't look at them when they are mixed with water, they make good water into a miasma, and water does not become water, but after separation, it is not worth mentioning when they return to their original appearance alone.

As a result, the composition of the coal, that is, the pulverized coal and the minced coal, are gathered together and dried into lumps, which weigh less than a ton.

The indigo dye was less than coal, but only five hundred kilograms.

These things were quickly sent to where they belonged, and then the entire Heishui River basin became a clear sky, clean earth, sparkling water waves, and the air was fragrant.

At the same time, the framework of the whole area has been built, which is the kind of pastoral style that crisscrosses the countryside, with a longitudinal trunk canal every 500 meters from east to west, and a horizontal trunk canal every 100 meters from north to south.

The water source of these trunk canals is connected to the Kahan Water System.

Regional streams agree to be incorporated into the system, and if they are well watered, they can be transported to the main trunk canal with excess.

Any shortfall is made up from the main trunk canal.

The smallest basic part of the system, with quality assurance, the entire Jiahan system, has the conditions to meet the standards of the kingdom of heaven.
