Protecting rivers Starting with me, what we should do about river protection

There are too many rivers that are alive, and there is water and there is life, so river protection is first of all the protection of river water, including water quality protection (to prevent the discharge of various pollutants), water quantity protection (water source protection, such as preventing the downstream flow from being cut off due to random water diversion, etc.);

Water can carry a boat, and water can also capsize a boat. Therefore, if the river is favorable, it is necessary to study and protect the river landform, protect the river embankment, and protect scientific water conservancy facilities (such as the Dujiangyan Water Conservancy Project);

The water quality and hydrological characteristics of rivers are closely related to the state of the river basin, so in order to protect the river, it is necessary to protect the river basin, such as the protection of vegetation in the river basin, soil and water conservation, etc., only in this way can the fundamental problem of river protection be truly solved.

No pollutant discharge. Do not indiscriminately deforest.

Although the environment of today's highly developed earth looks very optimistic, there are very serious hidden dangers, which are all man-made: large-scale felling of trees, the establishment of chemical plants, and the indiscriminate discharge of harmful liquids. "The world emits more than 600 million tons of gases every year.

It is estimated that by mid-next century, one-third of the Earth's surface will be at risk of desertification, with 6 square kilometres of land desertified each year, threatening more than 60 countries. "How do you feel about seeing these staggering numbers, human beings? From the emergence of forest apes 23 million to 18 million years ago to the current era of highly developed human civilization, nature has "responded" to everyone's never-ending demands, which has further nurtured human greed.

To give an example: Mulan Creek in my country, which was originally a crystal clear river in the early 50s, is now a polluted river with extinct fish and shrimp, adding another scar to our mother earth. Isn't this a heavy wake-up call for mankind?

Therefore, I solemnly advise those who are not yet enlightened: First, if human beings want to conquer the terrible nature, they must respect nature. We should be cautious about transforming nature, and we must be bold and bold in practice and improvement, so that we can control nature and develop our own interests in harmony with nature, and we must not repeat the mistake of "polluting first, then rectifying" in the developed countries of the West.

Second, we need to start with me and choose a lifestyle that is conducive to protecting the environment. Be kind to our homeland, be kind to the earth, and create a better living environment. 1。

Conserve resources and reduce pollution (1) Take pride in saving water, turn off the faucet at any time to prevent dripping. (2) Use detergents with caution and use soap as much as possible to reduce the pollution of water by chemicals in detergents. 2。

Green consumption and environmental protection choice (1) Reduce water and air pollution with unleaded gasoline, cadmium-free lead batteries, and phosphorus-free detergents. (2) Purchase low-pressure household refrigeration appliances and non-plastic mousse to reduce pollution to the ozone layer. 3。

Reuse and reuse Use as few disposables as possible and use durable goods as much as possible. For example, do not use disposable plastics and lunch boxes to reduce white pollution; Do not use disposable chopsticks; Bring your own shopping bag or carrycot. 4。

Classification** Recycling Do not litter waste batteries, waste plastics and other garbage and waste; Waste will be sorted and put into waste, turning waste into treasure, recycling resources, and benefiting mankind. 5。Protecting nature and coexisting with all things, not hunting and using rare animals and protected animals, caring for and protecting wild animals and plants; Afforestation, take care of every inch of green space, every flower, every tree around us.

6。Pay attention to hygiene and protect the environment No spitting, no littering, no smoking in public places, and no noise. As a primary school student in the new era, I advocate for my classmates to raise awareness of environmental protection, and I also recommend that uncles and aunts join us to contribute to the protection of the environment and the benefit of future generations.

Because: to protect the environment, there is no time to delay!

Preventing soil erosion caused by indiscriminate felling of trees can reduce the flow of sediment and prevent flooding and other accidents, which also warns of the urgency of human beings to protect the earth.

** Take water control as the center, unified planning, comprehensive improvement, scientific management, rational utilization, and ecological harmony as the principles;

Citizens should build awareness and save water as a measure.

Maintain species diversity while being aware of invasive alien species.

Conservation of vegetation. Prevent water pollution.

Pay attention to monitor the pH value of the river, find abnormalities in time and deal with them.

1. Physical method: sewage interception and diversion, water diversion and sewage flushing, sediment dredging, aeration and reoxygenation;

2. Chemical method: chemical algae removal, chemical fixation of heavy metals;

3. Biological method: biological contact oxidation, ecological restoration.

Sewage interception and diversion is to build a rainwater and sewage pipe network to collect the sewage that was originally directly discharged into the urban river to the urban sewage treatment plant or constructed wetland, and then discharge it after the treatment reaches the standard, thereby reducing the total amount of pollutants discharged into the river;

Water diversion and sewage flushing is actually to replace the polluted river water of the river by cleaning the river water, and dilute or bring the pollutants in the original polluted river into the downstream, so as to reduce the pollution load of the river and improve the self-purification capacity of the river water.

Sediment dredging is to reduce the release of pollutants in the sediment to the water body through the dredging of the sediment, which can permanently remove the pollutants in the sediment and effectively reduce endogenous pollution.

The aeration and reoxygenation technology is mainly used to deal with the sudden pollution of the river, that is, to carry out artificial reoxygenation for the river water at the appropriate position, improve the dissolved oxygen level of the water body, restore the vitality of aerobic organisms in the water body, and enhance the self-purification ability of the water body, so as to improve the water quality of the river;

Chemical algae removal is to destroy the collagen in the water body by adding chemicals, so as to achieve the purpose of algae removal;

Chemical fixation of heavy metals means that the heavy metals in the river sediment will enter the water body in an ionic state or a certain bound state under certain conditions, but by adding alkaline substances and raising the pH value of the river water, the heavy metals will form insoluble precipitates such as silicates, carbonates, hydroxides, etc., which will be fixed in the sediment.

The biological contact oxidation process is mainly based on the biofilm attached to the natural riverbed, artificially filled filter material and other carriers, and removes pollutants in river water through adsorption, degradation and filtration under the conditions of artificial assisted aeration or direct use of dissolved oxygen in water.

River ecological restoration refers to the use of ecosystem principles, taking various methods to repair damaged water ecosystems, restore ecological groups and structures in rivers, so that river ecosystems have reasonable organizational structure and good operation functions, and can remain stable under long-term or sudden disturbances.

Clean rivers need to be protected, and polluted rivers need to be treated and restored. There are four main measures:

Source control: sewage interception, source emission reduction, sewage treatment. Intercept sewage from the source, prevent the spread of pollution, lead to more pollution, strengthen capital investment, reduce emissions at the source, and treat sewage.

Water quality improvement: environmental engineering means are the main means, supplemented by ecological means. Remediation of polluted water, protection of water sources, establishment of nature reserves, and wetland reserves.

Ecological governance: ecological means are the main means, supplemented by environmental engineering means. Increase the treatment of polluted water, plant trees, intercept soil from entering rivers, and restrict or rectify highly polluting factories. Establish awareness of ecological protection.

Ecological restoration: the restoration of a single species, the restoration of ecosystems, and the restoration of ecosystem services. Protect wild animals, improve the ecological chain of rivers, and promote the sustainable development of the environment and ecology.

Rivers are a great gift from nature to human beings, and the origin, survival and development of human beings are inseparable from rivers. We need to be kind to the rivers, kind to nature, and kind to the earth.

The main thing about protecting rivers is to keep their water from being polluted.

1.Enterprises that pollute water sources should be located in the lower reaches of the river, and these specialized enterprises should also be discharged after sewage treatment that is guaranteed to be excluded (from the perspective of enterprises).

2.Residents' domestic sewage should also be disposed of and discharged, garbage dumping into rivers should be prohibited, and the use of phosphorus-containing laundry detergent should be reduced (from the perspective of residents' daily life).

3.The state should do a good job in protective measures, plant trees, conserve water and soil, strengthen supervision, and properly handle the relationship between economic development and natural ecology.

The ecological service functions of rivers are mainly in four aspects: supply, regulation, culture and support.

1.Supply: water supply value, food production, aquatic products, hydroelectric power.

2.Regulation: water storage, flood storage, erosion control, river sediment transport, purification function, atmospheric regulation, wind and sand suppression.

3.Culture: recreation, landscape aesthetics, water culture, education and scientific research.

4.Supports: Biodiversity, soil formation, nutrient cycling.

Don't throw trash cans (???) Protecting the Daguan River is everyone's responsibility.

Save water and keep it flowing!

Do not discharge waste water and protect the ecological environment of the waters!

Don't over-fish, protect the ecological balance of the waters!

Don't overdo quarrying, protect the riverbed from sagging!!
