1. Crops and water are inseparable. Crops can grow well thanks to water.
2. Water can help people generate electricity.
3. Water can irrigate crops and make crops grow more efficiently.
4. The water can be used for cooking and washing vegetables.
5. Water can remove dirt on the body and wash clothes.
6. Water is the main component of human body fluids and all life activities come from water. When the human body is dehydrated, it can cause dry mouth, wrinkles on the skin, confusion, etc. Water plays an important role in the metabolism of the human body.
Detailed information:
1. What is the impact of water pollution on industrial and agricultural production?
Industrial productionand agricultural not only requires sufficient water, but also has a certain impact on water quality requirements. Otherwise, it will cause great losses to industry and agriculture, especially the use of polluted water in the process of industrial and agricultural production, which will cause serious harm to human beings.
Industrial equipment will be damaged and product quality will be seriously affected. This changes the chemical composition of the soil and reduces its fertility, leading to reduced crop yields and serious pollution. Allow cities to increase wastewater treatment costs for domestic and industrial water.
2. What harm does water pollution cause to aquatic life?
A variety of aquatic animals and plants live in water. There are complex exchanges of matter and energy between organisms and water, andbetween organisms, maintaining a dynamic equilibrium relationship in terms of quantity. But under the influence of human activities, this balance has been destroyed.
The economic advantages of hydropower are long economic life and low operating costs.
The main advantage of hydroelectric power is that it eliminates the cost of fuel.
The cost of operating hydroelectric power plants is virtually unaffected by the rising prices of fossil fuels such as oil, natural gas and coal. Since hydroelectric power does not require fuel, it is not critical for this type of power plant.
Hydroelectric power plants have a longer economic life than fuel-fired power plants. Some hydroelectric plants built 50 to 100 years ago around the world are still in operation.
Since most cenSince hydroelectric plants operate automatically and require fewer workers under normal operating conditions, the labor cost of operating these plants is often lower. The construction of hydroelectric power stations can relatively reduce the cost of dam construction. and also add useful dividends to the operating expenses of the dam. Calculations show that China's Three Gorges Dam can recoup the investment in dam construction after 5-8 years of power generation.
Hydroelectric power generation involves using hydraulic energy (with head of water) to push hydraulic machinery (water turbine) to rotate, converting the energy of the water into energy mechanical if another type of machinery (generator) is connected to it. the water turbine, it will rotate with the water turbine. A call can be sent this time. The mechanical energy is convertedin electrical energy. In a way, hydropower is the process of converting the potential energy of water into mechanical energy and then into electrical energy.
Characteristics of hydropower: regeneration of hydropower, full utilization of water resources, storage and regulation of hydropower, reversibility of hydropower, flexibility of unit labor, low cost of production and high efficiency of hydroelectricity. High, which is conducive to improving the ecological environment, hydropower construction is limited by natural conditions.
Advantages of hydropower: Hydropower is a renewable energy source, has comprehensive advantages, can be adjusted, can be reversible, and has a high degree of mobility in operation. The cost of hydropower is low and the cost of construction. is not high Hydroelectric power stations The utilization raten energy is high and it is conducive to improving the ecological environment.
