Can you think of anything you can do to prevent acid rain

Causes: 1Combustible gas pollution includes motor vehicles such as automobiles.

2.Waste gas pollution in the chemical industry.

3.Combustion of coal

Acid rain is a disastrous weather, acid rain is almost as sour as vinegar, falling on people's bodies and making people feel burning. It is formed due to the burning of a large amount of oil and natural gas, emitting carbon dioxide and oxides containing sulfur and nitrogen, and entering the atmosphere, where a chemical reaction occurs in the air to become sulfuric acid and nitric acid, which fall to the ground along with rain.

At present, the prevention measures of acid rain are mainly to reduce the use of fossil fuels, reform the comprehensive utilization of production processes, and control pollutants in the production process.

Method: 1Improve the quality of fossil fuels, improve the exhaust emission devices of motor vehicles, and reduce the SO2 content in exhaust gases.

2.Limit the number and location of high-polluting factories and enforce exhaust emission purification.

3.Reduce the use of fossil fuels and make more use of pollution-free green energy, such as hydropower, tidal energy, solar energy, nuclear energy (safe nuclear energy), etc.

At present, the fossil energy used by humans is an important cause of acid rain, especially the combustion of coal, which contains sulfur, nitrogen and other elements in addition to carbon. Sulfur and nitrogen combustion produces sulfur dioxide, nitrogen dioxide and other oxides, and acid rain occurs when emitted into the air and comes into contact with a large amount of agglutination of water vapor.

Sulfur is also present in many fuels (e.g. coal) to remove sulfur from the fuel. Strengthen the treatment of exhaust gases from factories and automobiles. Rationally arrange the industrial layout, and arrange heavy polluting enterprises such as iron and steel plants to remote areas and areas with better air circulation.

Reduce the amount of S or SO2 emitted in industrial production.

1. Reduce the amount of sulfur dioxide emitted by industrial enterprises;

2. Reduce vehicle exhaust emissions;

3. Vigorously develop wind, nuclear, solar and other energy sources;

Drive less private cars.

Factory exhaust gases should be treated.

Coal burning is best treated with clean coal technology.

Less straw burning in rural areas.

In winter, coal stoves are used less for heating.

In short, it would be good to avoid substances such as sulfur and nitrogen.

Reduction of exhaust gases in industrial production.

The best thing to do is to deal with the exhaust gas.

1. What is acid rain?

The official name for acid rain is acid sedimentation. It refers to atmospheric precipitation such as rain, snow, fog, and hail with a pH value less than that. It can be divided into:"Wet sedimentation"with"Dry sedimentation"There are two categories, the former refers to all gaseous pollutants or granular pollutants that fall to the ground with precipitation patterns such as rain, snow, fog or hail, and the latter refers to some acids carried by dust falling from the sky on days when it does not rain.

The following Xianglan scientific instrument will explain acid rain to you in detail.

2. The formation of acid rain.

Acid rain is mainly caused by man-made emissions of large amounts of acidic substances into the atmosphere. China's acid rain is mainly formed by burning a large amount of coal with high sulfur content, mostly sulfuric acid rain, less nitric acid rain, in addition, the exhaust gas emitted by various motor vehicles is also an important reason for the formation of acid rain.

3. Prevention and control measures of acid rain.

1 use. Raw coal desulfurization technology removes about 40% to 60% of inorganic sulfur from coal burning.

2.Priority is given to low-sulphur fuels, such as low-sulphur coal and natural gas, which contain less sulphur.

3.Improve coal-fired technologies to reduce sulphur dioxide and nitrogen oxide emissions from coal combustion.

4.The flue gas formed after coal combustion is desulfurized before it is discharged into the atmosphere.

5.Develop new energy sources such as solar, wind, nuclear, combustible ice, etc.

Further information: Acid rain can lead to soil acidification, and acid rain can also accelerate the loss of soil mineral nutrients. Changing the soil structure, leading to soil impoverishment, affecting the normal development of plants; Acid rain can also induce plant pests and diseases, which can significantly reduce crop yields. Acid rain can be very harmful to forest plants.

The longer the leaves are in contact with acid rain, the more severe the damage will be. In areas with less than the pH value of precipitation, a large number of yellow leaves appeared in the Masson pine forest, Huashan pine and fir forest, and the forest fell off in patches.

Legal basis: The "Eleventh Five-Year Plan" for the prevention and control of national acid rain and sulfur dioxide pollution, all regions and relevant departments should closely combine the overall deployment of the current energy conservation and emission reduction work, strictly implement the total sulfur dioxide emission control plan, control the growth trend of nitrogen oxide emissions, and ensure that by 2010, the total sulfur dioxide emissions in the country will be reduced by 10% compared with 2005, effectively control acid rain pollution, and reduce the concentration of sulfur dioxide in urban air.

Levy SO2 emission charges, emission taxes, product taxes (including fuel taxes), emissions trading and some economic subsidies. 3. In the measures to strengthen supervision and management, understand the concept of cleaner production and sustainable development. Both concepts emphasize process management.

4. Reasonable industrial layout and urban planning are conducive to controlling the occurrence of acid rain. 5. The use of low-sulfur coal, saving coal, and sulfur fixation of briquette are conducive to preventing the occurrence of acid rain. 6. The concept of sulfur fixation in briquette.

The so-called sulfur fixation of briquette is to add sulfur fixing agent during briquette processing, and the coal does not discharge SO2 when burning, so as to achieve sulfur fixation in coal, and the sulfur fixation rate can reach about 50%. 7. Increasing the proportion of non-polluting or less polluting energy will make a great contribution to reducing SO2 emissions. 8. The methods of controlling automobile exhaust are:

Formulating exhaust emission standards for various types of vehicles; vigorously develop public transport; use of unleaded petrol; installation of exhaust gas purifiers and energy-saving devices; Use of "green cars", etc. 9. Expanding the green area and actively participating in the public is conducive to the prevention and control of acid rain.

Coal desulfurization, waste disposal, and development of new energy.

After suffering from acid rain for many years, many countries in Europe and North America, which have suffered the most acid rain in the world, have finally realized that the atmosphere knows no borders, and the prevention and control of acid rain is an international environmental problem, which cannot be solved by one country alone, and must jointly take countermeasures to reduce the emission of sulfur oxides and nitrogen oxides. After many consultations, the Convention on the Control of Long-Range Transboundary Air Pollution was adopted at the United Nations Economic Commission for Europe (UNECE) Conference of Environment Ministers in Geneva in November 1979 and entered into force in 1983. The Convention stipulates that by the end of 1993, States parties must reduce sulphur dioxide emissions to 70 per cent of 1980 levels.

Thirty-two countries, including Europe and North America, have signed the convention. In order to meet the promises, most countries have taken proactive measures by enacting regulations to reduce acid-causing emissions. Specifically, countries should do a good job in preventing acid rain from the following aspects:

1.Develop new energy sources, such as hydrogen, solar energy, hydropower, tidal energy, geothermal energy, etc., to minimize air pollution.

2.Use coal-fired desulphurization technology to reduce sulphur dioxide emissions.

3.Industrial production emissions are discharged after treatment.

4.Individuals are encouraged to drive less and travel more by public transportation.

5.Promote the use of cleaner energy such as natural gas or electricity and less coal.
