Tanghe, also known as Wenruitanghe, has a total length of 1,178.4 kilometers (including small and small branches), a river flow of 913 million cubic meters, covering an area of ​​740 square kilometers, a dense river channel water network, and numerous tributaries. The entire water system spans the "three districts and one city" covering Ruicheng, Ouhai, Longwan, and Wencheng.

Any place with cities and populations can see the flow of the Wenruitang River.

In addition, the Tanghe water system itself has multifunctional functions such as irrigation, drainage, and river transportation. I don’t know how many people in Wencheng and Ruicheng areas have been nurtured from ancient times to the present.

Therefore, this Wenruitang River is also known as Ruicheng, the mother river of Wencheng.

If time goes back for decades, the people living along the river will be counting on this pond and living a life!

What about washing clothes, washing rice, swimming in the river when the weather is hot, and you can still fish in the river, touch shrimps and crabs when you are idle, which can be said to have affected all aspects of the people in Ruicheng.

Unfortunately, due to the early industrial start in Ruicheng and Wencheng, coupled with the prosperity of polluting industries such as leather making and tanning, countless sewage discharged into Tanghe every year.

After years of accumulation, the originally clean and clear pond river has long since become black and black.

As for the water quality of Tanghe, it has also dropped from the early Class 2 water quality to the current Class 5 water quality.

By the way, China roughly divides water quality in rivers, lakes and seas into five types.

Class 1 water quality is mainly suitable for source water and water sources in national nature reserves.

For example, the internationally famous Tibetan area, where the water bodies are all glaciers. The source water from the snow-capped mountains will not be contaminated with almost no pollution, and you can drink it directly by scooping it up.

Class 2 water quality is mainly suitable for centralized drinking water, first-level protection areas of surface water sources, such as some reservoirs in mountainous areas. Most of the water supply in our daily cities comes from this type of water source.

However, the quality of these two types of water is significantly lower than that of Class 1. If you want to supply people with daily drinking, you must also be processed and filtered by tap water plants in various regions.

As for the quality of these three types of water, you can’t drink them directly, unless you are not afraid of having a diarrhea and send them to the hospital.

This type of water quality has been slightly polluted to a certain extent. Although the water body looks clear, at most it can only go into the water to swim.

When the 4th category water quality comes, the pollution will become even more serious!

This type of polluted water quality can no longer be directly in contact with the body. To put it bluntly, it is impossible to even go into the water to swim.

Unless you are not afraid of any messy skin diseases or infections, you can rest assured to go and suck the carp.

As for drinking these four types of water, you don’t have to think about it. Unless you have a pitfall in your mind or if you have a long life, you will directly drink the four types of water.

It is the last category of inferior water quality, and the official reference is landscape water or agricultural watering water.

What is landscape water?

To put it simply, these inferior 5 types of water quality can only be seen with your eyes!

Can't touch or drink!

It doesn't even work to touch the skin!

Just imagine the worst pollution in the place where you live, the darkest and dirtiest, and the river surface is filled with garbage, which is almost the worst water quality.

As for the Ruitang River that Chen Hao wanted to manage, it was also a clean horse in his early years.

My father said that at that time they could all scoop water and cook rice directly from the river, which shows how clean and clear the water quality of the Tanghe River was once.

What about now?

Due to the large amount of industrial wastewater, domestic sewage, and domestic waste discharge, this mother river of Ruicheng people has long become the worst category of inferior water quality.

Not to mention going down to swim, it’s so damn black that it smells bad!

Of course, the leaders of Ruicheng and Wencheng have spent a lot of effort to manage this mother river.

Since 85% of the water quality of Tanghe River was detected in 2000, 85% of the total water quality was detected in Tanghe River. Wenshi District began to organize large-scale river management.

From 2000 to 2018, the average annual water control fund invested reached about 600 million. After 18 years of hard work, hundreds of billions have been invested one after another!

If you spend more than tens of billions of dollars, it would be fine if you can really manage the Wenruitang River.

Judging from Chen Hao's experience of living in Ruicheng as a child, the more than 10 billion he spent was like a waste of money!

Useless!

Tanghe is still damn dark until now!

The slightly better DC river may have a hint of green color, but it is still turbid and cannot be seen.

The rustic guy still remembers that when he went to school, there were ships of all sizes and excavators dredging the silt in the river channel every year, and various strange water purification devices were put into the river channel.

Whenever get out of class and school are over, Chen Hao would stop by the river with his classmates for a long time. However, after more than ten years of treatment, the areas where Tanghe should be dark are still dark and the pollution is still serious.

no way!

The sewage discharge along the way is really too serious!

Although environmental protection has been severe in recent years, the water quality of Tanghe River has accumulated over the years of sewage, and the amount of silt deposited at the bottom of the river is almost unimaginable.

It is almost a fantasy to clean the river at one time.

After all, the total length of this tributary has reached 1178.4 kilometers. Not to mention that it has been spent billions and entered it without any movement.

Even if we spend 10 times more and invest hundreds of billions of dollars, according to the existing governance methods, we still cannot completely manage the mother river of Ruicheng people.

Because the pollution of the Tanghe water system is too complicated!

In addition to the excessive heavy metals in the water body, the dumping of domestic sewage, industrial sewage and domestic waste, some tributaries have long since filled rivers and built roads, and the source has long been cut off from the source and become small pieces of stagnant water.

What is the concept of stagnant water?

It’s like a small pond that has no upstream source and downstream exit, and only relies on rain to store water!

Even the water flow is so fucking that he won’t move!

In addition, the phenomenon of secret discharge and discharge in factories along the river is serious, so it is almost impossible to reconstruct the inferior Class V Tang River water overnight into the second-class water quality that was originally capable of boiling rice.

However, this kind of thing that seems almost impossible for outsiders to complete, but it is another situation in the hands of the country bumpkin.

Because Chen Hao’s brain circuit is not comparable to that of ordinary people!

In addition, with the bug system of comic lottery, many impossible things have hope of realizing in his hands.
Chapter completed!
