What are the four dirtiest rivers in the world?

With the development of the country's economy, the lives of the people of the country have been greatly improved, and many people will save some money to travel on holidays while being satisfied with the status quo of life. The relationship between countries is also getting closer and closer, and more and more Chinese people yearn to travel abroad, but every country in the world has beautiful scenery and bad scenery, and every place has its opposite. Today I will take you to learn about the 4 dirtiest rivers in the world, China is also on the list, one of which is in China, do you know in **?

When it comes to dirty rivers, everyone immediately thinks of the Ganges River in India. That's right, the first one to introduce is the Ganges, travelers who have been to India know that the Ganges is the mother river of India, but it has not been taken seriously and protected, the locals are instead soaking corpses in the Ganges, bathing, throwing garbage, etc., they believe that the water in the Ganges is sacred, can purify the soul, and even some merchants will make the Ganges water into drinks and sell them.

The second is the Yellow River in China, which is also the mother river, but its dirtiness is another degree of dirt, and it is not a deliberate sabotage. The water of the Yellow River is very turbid, which is inseparable from the environment along the river. Visitors who have been around will find that there is a lot of weathered sand along the river that will flow into the sea, causing the river to become turbid, but the locals are also very helpless about this.

The third is the Thames River in England, where is it dirty? It is said that after the Industrial Revolution, many factories were built along the River Thames in England, which brought economic benefits but also polluted water sources. The factories there discharge wastewater directly, causing a lot of harmful substances to appear in the river, and it smells bad.

The last river is the Yamuna River, which is also a river in India and is the largest tributary of the Ganges. The Yamuna River is more polluted than the Ganges, and the tour guide learned that experts have taken water samples from the Yamuna River and tested the bacteria level more than 3,000 times the safe level, which shows how serious the pollution is.

India accounts for two of the four dirtiest rivers in the world. I wonder if there are any rivers in your hometown that are also polluted?

The first is the Ganges, which is the mother river of India, but it is not taken seriously and protected, and they believe that the water in the Ganges is sacred and purifies the mind. The second is the Yellow River in our country, but its dirtiness is another degree of dirty, not man-made deliberate destruction, the water of the Yellow River is very turbid, which has an inseparable relationship with the environment along the coast, there are many weathered sand along the coast will enter the sea with the river, causing the river to be turbid. The third Thames River in the United Kingdom, it is said that after the Industrial Revolution, many factories were built along the Thames River in the United Kingdom, which brought economic benefits but also polluted the water source.

The last river is the Yamuna River, which is also a river in India, the largest tributary of the Ganges, and the Yamuna River is more polluted than the Ganges, and experts have taken water from the Yamuna River for testing, and the bacterial level is more than 3,000 times higher than the safety standard, which shows how serious the pollution is.

1.Ganges, India. In the minds of Chinese tourists, the Ganges River, like the Taj Mahal, is the two most representative of India.

But the local people will bathe in the Ganges, will throw all kinds of garbage into the river, coupled with the local custom of water burial, people are also directly put into the Ganges after death, so now the Ganges River is very polluted.

2.Yamuna River, India. Apart from the Ganges, there is another river in India that is not very dirty, even dirtier than the Ganges.

It is said that some water quality experts took water samples from here and tested them to find more than 3,000 times the safe amount of bacteria. And there were people who were sent to the hospital for bathing in this river, lying down for days, let alone drinking the water from the river, and they couldn't even think about it.

3.River Thames, UK. Many factories have been built on both sides of the river, and the industrial wastewater produced flows directly into the river, which also includes many harmful substances and causes serious pollution of the river.

4.Yellow River, China. The Yellow River is a big river in China, and many people feel this way when it comes to saying that the Yellow River is dirty. Every time they pass by the Yellow River, visitors can find that the water is very muddy, even a bit like muddy water.

1. Greenland Blue River

The water of the Blue River is gorgeous turquoise.

It is runoff from melting glaciers. It is located in Greenland.

Above the river is a long line of blue liquid, which was found on the Petermann Glacier in Greenland, which is melting and the river appears every year in a new and fascinating shape. The glacier melts clean and clear, filling the bottom of the river, which is why it is ultimately flawless.

2. BrazilRioDapraTower River

The reason why Rio da Plata, Brazil is so clear is because the limestone in the ground helps to filter the water. There are a number of popular clear water rivers around Rio da Plata, Brazil. This is because the high content of underground limestone filters out sediment-free water and helps neutralize its acidity.

This means that the Rio da Plata River is one of the clearest rivers in the world and one of the most popular.

Tourists and locals alike love to explore the icy waters with wetsuits. From above, it is a glass mirror of the sky above, reflecting everything back to the floor layer below itself. From below, it's like teleporting to another world with colorful fish and plants.

3. Sucuri River in Rio, Brazil

Rio Sucuri, Brazil is a river that is also located near Rio da Plata, Brazil. The water of these springs is beautiful, clear, and cool. Many people enjoy taking a boat out into the water to experience the scenery and watch fish and other river creatures hover between their legs and float forward.

From above, as the depth increases, the water takes on a bright azure blue with a darker blue tinge. Everything is visible, as if water were glass. It is surrounded by lush greenery, and traveling along it feels like you've escaped to a whole new world.

4. Verzasca River, Switzerland

The Swiss Verzasca River is located in the Swiss canton of Ticino and is 30 km long. From above, the river is emerald green and dark blue.

The gradient color is sometimes neatly divided along the river.

When flush with water, its length is a transparent emerald.

Flowing through stones polished over the years, the river is a beautiful testimony to nature and an idyllic place for tourists to visit.

There are natural jacuzzis, and the water enters the small turf through a hole in the rock where people can rest. The stones along the river are easy to cross. The water at the bottom of the pool is cool and clear, so you can see the stone landscape that makes up its base.

During the summer months, it is a popular spot for tourists or locals to swim and spend the day exploring.

5. Jiuzhaigou, China

Jiuzhaigou is a Chinese national park consisting of a series of lakes, rivers and waterfalls.

It's not just a river, it's a nature reserve and wilderness area found in China's Sichuan Province. It has clear rivers and lakes, and it also has many waterfalls and lakes as well as the rivers that connect them.

Its entire area is pure and unpolluted, and like the other rivers mentioned earlier, it is surrounded by water from forests and woodlands, which originally came from the melting of glaciers. The water in Jiuzhaigou takes on blue and green hues, and many lakes take on different hues depending on the composition of the surrounding soil and rocks.

The dirtiest rivers in the world are the Ganges, Yamuna, Thames, and Yellow River in India.

1. The Ganges River in India.

The Ganges River is revered by Indians as the "Holy River" and "Mother of India", and is a sacred symbol in the hearts of every Indian, so many Indians will come to the Ganges to bathe in the hope of washing away their sins. Secondly, the surrounding residents will also wash clothes, vegetables, and urinate in the river. Residents also like to be cremated by the Ganges River and scatter their ashes into the Ganges.

Many domestic animals are also thrown directly into the Ganges after they die, leaving the river with dirty water.

2. The Yamuna River.

The Yamuna River is currently the most polluted river in India, and because it is located in the capital Delhi, it has become a major source of pollution, accounting for about 80% of the city's industrial wastewater and domestic sewage. The Yamuna River is the longest tributary of the Ganges River in India, and because the Ganges River is heavily polluted, it inevitably has a certain impact on the Yamuna River. The main reason is that most people in India are not environmentally conscious, resulting in a certain amount of pollution in many rivers in India.

3. The River Thames.

The River Thames is the second largest river in the United Kingdom and originates in the southwest of England. The River Thames, which has been polluted since the Industrial Revolution, stenched under the scorching sun, and the pungent smell enveloped London with a heat wave. Garbage from 3 million people floats and ferments on the surface of the River Thames.

Londoners are bitter and call it "the greatest stink". From the princes and nobles to the common people, no one escaped the clutches of the great stench.

Fourth, the Yellow River. The Yellow River is located in China, and unlike other rivers, the "dirty" of the Yellow River is not really dirty, but the sediment carried by the Yellow River when it flows through the Loess Plateau in the middle and upper reaches of the Yellow River, and the water of the Yellow River turns into a turbid yellow, hence the name of the Yellow River. In the upper reaches of the Yellow River, the water of the Yellow River is still very clear.

It's just that in the middle and lower reaches, the topography and geology cause the water to flow rapidly and mix with sediment, creating the illusion that the water is dirty.

How to clean up polluted rivers

1.Physicochemical Method:

The physical and chemical methods mainly use physical and chemical principles to continuously electrolyze, flocculation, catalytic oxidation, filtration and other methods to nitrate, degrade, decompose and absorb harmful substances in polluted water. This method has obvious effect in the treatment of polluted water bodies in river channels, but the investment cost is large, the operating cost is high, and it is not suitable for the treatment of large water bodies.

2.Ecological Wetland Restoration Law:

Ecological wetlands have the function of degrading pollutants and purifying water quality, so that polluted water bodies flow through ecological wetlands to gradually degrade pollutants and improve water quality standards. However, ecological wetlands require a large area and low purification efficiency. At present, there are no conditions for building large-scale ecological wetlands, and it is impossible to treat heavily polluted water sources, and even the ecological wetlands will be damaged, and plants will die to produce corrosive substances, which will be released into the water body, causing more serious environmental pollution.

The cleanest river in the world is:Amazon RiverThe Amazon River is the most famous river in the world and is located in South America.

It is a river rich in hydraulic resources, with a total length of 6,440 kilometers and a water area of 10,000 square kilometers.

It is a very large river that flows through many countries and regions and is a source of life for people all over the world.

Features of the Amazon River

The rivers of the Amazon have different characteristics, with large drops between the upper rivers, rapids and large flows. But after reaching the middle reach, the river becomes wider, the gap between the rivers becomes smaller, and the flow velocity decreases.

The Amazon River has obvious advantages in hydraulic resources, so the river navigation is very developed. The Amazon River has a tropical climate and its origins are in the Andes.

The river has a lot of water. It has abundant precipitation and a large flow. When precipitation is frequent, its water flow reaches 280,000 cubic meters per second.

The dirtiest river in China is the Yellow River.

The Yellow River is one of the dirtiest rivers in China, and the river water is heavily polluted, with low dissolved oxygen, poor water quality, and the indiscriminate discharge of fertilizers, pesticides, and other pollutants are also the main causes of water pollution in the river. The Yellow River is one of the longest rivers in the world and the second longest river in China (also known as the second largest river).

The total length of the Yellow River is about 5,464 kilometers, and the area of its basin is about 752443 square kilometers according to the People's Daily Online, and the Ministry of Water Resources ** "Yellow River Network" is recorded as: the total area of the basin is 10,000 square kilometers (including the area of the inflow area of 10,000 square kilometers).

The winter is long and the summer is short, and the temperature and temperature of the front rock in winter and summer are very different, and the temperature of Yinbend in the season varies significantly.

Distribution of the Yellow River:

The middle and upper reaches of the Yellow River are mainly mountainous, and the middle and lower reaches are dominated by plains and hills. Because the middle section of the river flows through the Loess Plateau region of China, it carries a large amount of sediment, so it is also known as the river with the most sediment content in the world. But in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization.

The Yellow River is the main birthplace of Chinese civilization, and the Chinese call it "the mother river of jujubes". Every year, 1.6 billion tons of sediment are carried, of which 1.2 billion tons flow into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming an alluvial plain that is conducive to cultivation.

4. The Yangtze River and the Yellow River are the two most famous "mother rivers" in China, one in the south and the other in the north. The Yangtze River is a well-known river with a lot of pollution levels now. The Yangtze River is more than 6,300 kilometers long, and its pollution is mainly concentrated in the lower reaches, and the river water is basically very greasy.

The main reason for being so dirty is that the downstream is the Yangtze River Delta region, where there are many industries and factories, and there are many wastewater discharges. However, the flow of the Yangtze River is large, and the effect of flushing and release is relatively obvious. All of them can only be at the bottom.

3. The Yellow River is the most famous river in China, and it is the mother river of the Chinese nation. The "dirty" of the Yellow River is actually somewhat wronged, because this "dirty" is mainly "yellow". The Yellow River flows through the Loess Plateau region of China, and the yellow sediment of the Great Shiyuan is impacted and drifts with the waves, dyeing the Yellow River yellow.

Of course, it is not because of the yellow sand and loess. The pollution situation in the lower reaches of the Yellow River is indeed not light, and the main reason is naturally the discharge of industrial sewage. 2. Liaohe RiverThe Liaohe River is one of the seven major rivers in China, a famous river in northern China, and also the "Liao" in Liaoning Province.

The pollution of the Liaohe River mainly comes from the papermaking enterprises in the northeast region, as well as the bottom of the urban domestic sewage treatment rate. Before 2008, the dirtiness of the Liao River had affected the lives of residents. Later, Liaoning Province began to implement the "three major projects" and "three major battles", and began to control the Liao River from the tributaries by breaking them one by one.

It's a lot better now. 1. In 2016, China's Ministry of Environmental Protection released the national environmental quality status of surface water. Among them, the water quality of the Pearl River and the Yangtze River is good, the Yellow River is slightly polluted, the Liao River is moderately polluted, and the heavily polluted is the Haisoshou River Basin.

The Haihe River flows through the Beijing-Tianjin-Tang Industrial Zone, which is the most developed heavy industry in northern China, and the industrial wastewater and climate are dry, and the flow of the Haihe River is small among the top ten rivers in China. All these have led to the "notoriety" of the Haihe River, which is still a problem to this day.
