You know, it is not just ordinary netizens who are watching this water control event at this moment.

Since this water control project targets a Class V water body that has been polluted for decades, and the total length of this pond and river system has exceeded thousands of kilometers.

Once this length of polluted water system is successfully managed, then this case of using [destained water plants] to manage river water systems can be naturally promoted to polluted rivers throughout China and even the world.

Therefore, when the hot headlines were pushing this unprecedented river management activity, water conservancy and environmental protection experts from all over China, as well as staff from water conservancy bureaus from all over the country participated in the live broadcast and watched.

"In just 30 minutes, the sewage can be purified to the point where it can be consumed directly?"

"If this kind of [stainless water plants] can be promoted here, then the management plans for several stubbornly polluted rivers in the county will be implemented!"

"Yes! The most important thing is that in addition to purifying water, this [stainless water plant] also has unexpected reinforcement effect on the silt in the water body."

"If the silt at the bottom of the riverbed can be as solidified as in the live broadcast screen, then the traditional dredging method will completely bid farewell to the historical stage."

The traditional dredging method mentioned by these experts and scholars is actually the most common river channel management and dredging method in China. It is divided into three steps:

The first step is called a "coffindam". It uses bagged sand and soil to stack temporary dams on the upstream and downstream of the river that needs to be cleaned, and cut off the river.

The second step is called "water pumping". As the name suggests, it means using a high-power sewage pump to completely drain the cut off river sewage, so that the silt at the bottom of the river bed can be completely exposed for subsequent cleaning.

The third step is to "clean up and transport", use a special sewage suction pump to pump away the silt on the surface of the riverbed, and then use a large tanker to transport the silt to a designated location for stacking.

Of course, due to the high cost of this type of special sewage suction pump, river management in many places cannot spend a lot of money to introduce such dredging equipment.

In the management of most rivers, we can only adopt more backward mechanical operation methods in a second-rate way. This is what we often use when we use excavators and sludge to clean and transport sludge.

Of course, some rivers with narrow rivers and not so deep rivers do not need to be used to build temporary dams such as "cofferdams".

When managing rivers, many places directly send excavators to start the water, dig gas randomly at the bottom of the riverbed, and then throw silt onto hulls such as sand transporters for silt transport.

However, this simple and crude operation method brings serious secondary pollution.

Liquid sludge will inevitably leak or lose during transportation.

If the tank truck for transfer is not well-sealed, it will be almost all the way, and the mud will have to be sprinkled all the way!

In addition to the excavator bucket, the liquid silt leaks half of the amount, and the operating efficiency can be said to be extremely low.

So much so that this traditional dredging method has been promoted in China for decades, but no particularly good river management cases have emerged.

But there is nothing we can do!

Who made China polluted too much water system?

If other high-tech dredging methods are used, the management funds that need to be consumed will be in full swing.

Although China has paid more and more attention to environmental protection in recent years, if we want to completely eliminate this traditional dredging method, we must find an effective and feasible alternative?

However, no matter how many experts and scholars study and plan, they cannot come up with a more effective follow-up plan than the traditional dredging method. This has made this rough and bold traditional dredging method rampant in China for decades.

Of course, it’s not just China that has no choice but to deal with this kind of river silt!

Even internationally, no efficient and feasible dredging technology has been developed so far.

Take the Thames River in England as an example. This river of mothers in the English people, which flowed through the capital Lamton, was no better than the Tang River in the 19th century.

A large amount of industrial wastewater and domestic sewage were discharged directly into the Thames River without treatment, and garbage along the coast was even piled up at will. The stench made the Queen of England almost silence her breath.

The English government, who had no choice but to invest a lot of money in river management.

As for their governance methods, they are also quite rough!

Every few kilometers away, a small sewage treatment plant is set up next to the river.

Good guy!

In the end, hundreds of sewage treatment plants were built in one breath, and the sewage problem in the Thames River was completely solved by quantitative change and quantitative change caused by qualitative change.

Unfortunately, the sewage problem has been solved, but the silt underneath has not made much progress.

Even if you enter the 21st century, you only need to travel to Lanton and you will find that the surface of the Thames River looks dark gray from a distance, with a clear and green river channel that should have.

In the end, the English government also planned not to invest money in the mud.

The method of changing birds was directly used to silt, and the silt at the bottom of the river was transported in large quantities and discarded into the ocean, which made the Thames look a little "clean".

Of course, people can’t manage a river well with the whole country’s strength!

According to the governance philosophy in England, it is almost unrealistic to build a sewage treatment plant every few kilometers in China with such a dense water network.

Take Tanghe in front of you as an example. If the Tanghe water system with a total length of more than 1,100 kilometers is used to use the English method, wouldn’t it be necessary to build thousands of small sewage treatment plants?

If this is true, then the people in Wen City and Ruicheng don’t have to do anything, and they all go to the sewage treatment plant to work?

Besides, even if the sewage is cured, what should I do if the silt in the pond and river are done?

You can't learn from England and all your luck is poured into the sea, right?

The workload of going to the sea alone is enough to let the staff of the Environmental Protection Bureau and Water Conservancy Bureau of the two places drink a pot!

Therefore, when these experts and scholars saw that [destaining water plants] had the effect of solidifying sludge in the live broadcast, they were all excited and burst into tears, and the phone in their hands kept dialing the old leaders they knew.

"Hello!"

"Old Mr. Dong?"

"It's me!"

"Xiao Liu from the Water Conservancy and Environmental Protection Laboratory!"

"Old Dong, I'll tell you, turn on the computer and surf the Internet to watch the live broadcast of xx TV station!"

"The traditional dredging method that has troubled our country for many years has finally found a feasible alternative!"
