Methods of water conservation in our country, knowledge about the protection of water resources.

When washing your hands, washing in a basin is more water-efficient than washing with a long stream of water, and the same is true when washing vegetables and fruits or washing dishes. Used water can be stored and reused.

The washing machine in the family consumes a lot of water, and in order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring that the clothes are clean.

This slanted shape is not for the sake of beauty or unconventionality, and the 10-degree inclined design has its own reason. When the washing drum is crooked by 10 degrees, its water level is relatively deepened, which can achieve the washing effect of a large amount of water. So it saves water.

People can't live without water for a day, water is the source of life, and cherishing water is cherishing one's own life!

Through various measures and ways, the use of water resources will not be wasted, so that the water quality will not be polluted, so as to promote the rational use of water resources. The main protection measures are: agricultural measures, forestry measures, soil and water conservation and engineering measures.

Water on the planet seems to be inexhaustible, but in fact, in terms of current human use, only fresh water is the main water resource, and only a small part of fresh water can be used by people. Freshwater is a renewable resource, and its renewability depends on the Earth's water cycle. With the development of industry and the increase of population, a large number of water bodies are polluted; In order to pump river water, many countries have built dams in the upper reaches of rivers, which has changed the flow of water and seriously affected the circulation and self-purification of water.

Many people imagine the Earth as a blue planet with 71% of its surface area covered with water. In fact, the water on the earth is saltwater, only fresh water. Nearly 70 per cent of freshwater is frozen in the ice sheets of Antarctica and Greenland, and most of the rest is soil water or deep groundwater, which is difficult to extract for human use.

Water from rivers, lakes, reservoirs and shallow groundwater is easier to extract for direct human use, but its amount is less than 1% of the world's freshwater, accounting for about all water on the planet.

The annual precipitation of the world's water resources falling on the continents is about.

110 trillion cubic meters, deducting the amount of water evaporated by the atmosphere and absorbed by plants, the world's river runoff is about one trillion cubic meters, and the average amount of water available per person per year is 7,300 cubic meters based on the world population in 1995. As a result of the growing world population, this average has fallen by 37 per cent since 1970.

1. Prohibit indiscriminate discharge: indiscriminate discharge refers to not discharging industrial wastewater into the water, domestic wastewater, etc., indiscriminate discharge refers to not throwing garbage into the water, and industrial wastewater will have a very large impact on water resources if it is not properly treated.

2. Pay attention to the construction of sewers: the purpose of establishing sewers is to drain water, which is of course to discharge urban wastewater and domestic wastewater, so it is very important to plan sewers reasonably.

3. Water conservation: Protecting water resources is not only about not polluting water, but also about saving water, there are many countries in the world that are short of water, cherish every drop of water we use, and do not waste it.

4. Publicize the knowledge of protecting water resources and improve the awareness of residents: Many people are not aware of the importance of protecting water resources, we can publicize the knowledge of protecting water resources, such as community publicity, radio, television and other channels to publicize and raise awareness in this regard.

5. Mutual supervision: If we see factories discharging industrial wastewater and farms discharging agricultural wastewater, we can report it, so that the relevant departments will rectify these places and achieve the purpose of protecting water resources.

Everyone says that water is the source of life, and protecting water resources is everyone's responsibility and obligation, so what should we do to effectively protect water resources, and what are the ways to protect water resources?

1. Cherish paper: The sharp increase in demand for paper is one of the reasons for the growth of wood consumption, the country's annual papermaking consumption of 10 million cubic meters of wood, more than 1.3 million tons of imported wood pulp, more than 4 million tons of imported paper, how many trees to cut down! The massive consumption of paper not only destroys forests, but also pollutes rivers and lakes due to the discharge of sewage from the production of pulp.

2. Increase forest area and conserve water sources: Forests have the functions of conserving and absorbing water sources, reducing ineffective evaporation and regulating microclimate, which has the significance of reducing water. It is of open source significance that forest areas and forest margins have the potential to increase precipitation.

3. Improve the comprehensive utilization of water resources: reservoirs can store floodwater, can also breed aquatic animals and plants, large water surfaces can be navigable, and some water bodies can also be opened up for tourism. The water used for hydroelectric power generation can be used for irrigation.

The water leaking in the canal system and in the field can be pumped out of the ground for use, and the water pumped out of the ground can also be repeatedly pumped and reused in the downstream of the irrigation area. Xinjiang is an arid region, and without irrigation, there will be no agriculture, and trying to increase the water diversion rate of rivers is equivalent to opening up water sources by properly draining the relationship between upstream and downstream water use.

The above is an introduction to the methods of protecting water resources, I hope it will be useful to you!

1. Improve the utilization rate of water resources and reduce the waste of water resources. The key to effective water conservation lies in the use of "reclaimed water", and the reuse of water resources is real. Economic levers can also be used to regulate the efficient use of water resources.

2. Improve equipment, strengthen management, and eliminate waste. Some equipment is aging, and the phenomenon of leakage and leakage is very serious, so the equipment should be updated and management strengthened. 3. Intensify the prevention and control of water pollution and the protection of water resources, and restore the ecological environment.

4. Vigorously develop greening and increase the area of forests to conserve water sources. 5. Comprehensive utilization of high water resources, water in the same space has the characteristics of comprehensive utilization.

6. It is necessary to mobilize the whole society to change the traditional concept of water use. It is necessary to call for water conservation in the whole society, use one water for multiple purposes, and fully recycle water. It is necessary to establish a sense of cherishing water and carry out the education of water resources warnings.

7. We must repentance and rationally develop water resources to avoid the destruction of water resources. The development of water resources includes the development of surface water resources and the development of groundwater resources.

8. Optimize the allocation of water resources and promote the sustainable use of water resources. 9. Strengthen environmental education and cultivate good water-saving habits. 10. Carry out water pollution prevention and control to realize the comprehensive utilization of water resources.

In the city, the approach of centralized sewage treatment can be adopted; Industrial enterprises must implement the "three simultaneous" system of environmental protection; Production sewage adopts corresponding sewage treatment measures according to its different nature.
