Question 1: How to solve air pollution (1) At present, due to the low efficiency of combustion devices, a lot of energy is consumed in the form of waste heat, resulting in thermal pollution. According to statistics, the thermal efficiency of civil combustion devices is about 10%-40%, industrial boilers are about 20%-70%, thermal power plants are about 40%, and nuclear power plants are about 33%. The average effective utilization rate of thermal energy in China is only about 30%. If the heat energy utilization rate is increased by 10%, it means that the heat pollution of 15% is controlled. It is entirely possible for China to increase its thermal efficiency to over 40% (equivalent to the level of industrialized countries). This can greatly reduce thermal pollution. (2) Using waste heat can also reduce thermal pollution. For example, waste steam from a factory is used for bathing through a heat exchanger, or waste heat is used for heating raw materials that need to be heated; It not only recovers waste heat, saves energy, but also prevents thermal pollution of the environment. (3) Reduce atmospheric thermal pollution by cooling. The direct discharge of hot steam and waste heat in many enterprises has caused pollution. It is a simple method to solve the thermal pollution that the hot waste gas is discharged after being cooled by cooling tower or cooling pool. There are two kinds of cooling towers: dry tower and wet tower. The drying tower is cooled by heat conduction and convection. The wet tower can be cooled by natural ventilation or accelerated by mechanical ventilation. Cooling towers are widely used in power stations, metallurgical plants and mines.

Problem 2: Solving air pollution more and preventing air pollution is a huge systematic project, which requires the joint efforts of individuals, collectives, countries and even countries all over the world. The following measures can be considered:

1, reducing pollutant emissions. Reforming the energy structure, using pollution-free energy's solar energy (such as solar energy, wind energy and hydropower) and low-pollution energy (such as natural gas), pretreating fuel (such as desulfurization before burning coal) and improving combustion technology can reduce pollution emissions. In addition, before pollutants enter the atmosphere, some pollutants in waste gas can be eliminated by dust removal and smoke elimination technology, condensation technology, liquid absorption technology and recycling technology, so as to reduce the amount of pollutants entering the atmosphere.

2, control emissions, make full use of the self-purification ability of the atmosphere. Different meteorological conditions have different atmospheric capacity of pollutants, and the same pollutant discharge will cause different pollutant concentrations. For areas and time periods with strong wind, good ventilation, strong turbulence and strong convection, the atmosphere has strong diffusion and dilution ability and can accept more activities of factories and mines. In the area and time period of inversion, the diffusion and dilution ability of the atmosphere is weak, and it cannot accept more pollutants, otherwise it will cause serious air pollution. Therefore, effective emission control should be carried out in different regions and different time periods.

3, site selection, chimney design, urban and industrial planning should be reasonable, don't exhaust too concentrated, don't cause repeated pollution, leading to serious pollution incidents in some areas.

4. Afforestation: Dense forests can reduce wind speed and reduce a lot of dust carried in the air. The surface of leaves is rough, some have fluff, and some can secrete mucus and oil, so they can absorb a lot of floating dust. Dusty leaves can continue to absorb dust after being washed by rain. Such reciprocating blocking and adsorption of dust can purify the air.

5. Start with yourself. Don't litter, a perfect city is everyone's responsibility.

Question 3: How to solve the air pollution problem? You can plant some plants that purify the air indoors, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum, Dendrocalamus, etc. These are natural scavengers. The research shows that aloe vera, Eupatorium odoratum and chlorophyllin have strong absorption ability to indoor harmful gas formaldehyde.

Question 4: How to solve the problem of air pollution in the sky? 10: First, control the pollution emissions of industrial enterprises. Optimize the process flow and try not to discharge pollutants or less: the pollution that must be discharged can't be controlled, and taking control measures to control the pollution to the minimum is not only a matter of reaching the standard. In fact, the location of industrial enterprises is also a key issue. Often the location is improper, even if the discharge reaches the standard, it will cause local air pollution.

The second is to increase the self-purification ability of nature. Maintain ecological balance, plant more trees, increase the proportion of green GDP and so on.

Finally, there are social problems. Air pollution has something to do with you and me. Only when everyone realizes the harm of air pollution can our sky be blue forever.

Question 5: How to prevent air pollution is a complicated problem. We must consider various factors and take various measures to comprehensively manage them. For example, cooking and heating can use natural gas, coal gas and biogas, and try not to use coal or use less coal to reduce the air pollution caused by a large number of sulfides produced by coal burning; It is necessary to clean up and properly dispose of industrial and construction garbage and waste residue in time to reduce air pollution caused by ground dust; Cars should also use unleaded gasoline as much as possible, or use other fuels that do not pollute the air as much as possible. People can also use cars as little as possible and switch to vehicles that don't pollute the air. Zhangjiagang City, Jiangsu Province, which once won the title of national environmental protection model city, is a small city. In order to reduce urban air pollution, special regulations have been made: tractors and motorcycles are prohibited from entering the city. People (including drivers) on the bus want to go to the downtown area, and four entrances of the downtown area have specially prepared 1500 bicycles for them to use. In addition to the above measures, the most economical and effective way for the majority of grassroots women cadres is to mobilize the majority of women and the masses to actively participate in afforestation. Because tree planting is an air filter, it has the function of absorbing all kinds of harmful and toxic gases; Dense jungle can stop the dust blown by strong winds; Trees also have the function of regulating air composition. Plant photosynthesis means inhaling carbon dioxide and exhaling oxygen. Many plants can also absorb sulfur dioxide and kill germs. Therefore, we should vigorously plant trees and flowers.

Question 6: How to solve air pollution? Solutions to indoor air pollution V. Scope of application ◆ Living environment: living room, bathroom, office building, hotel, Internet cafe, KTV, etc. ◆ Transportation system: cars, trains, subways, planes, ships, elevators and other means of transportation; ◆ Medical system: hospitals, hospitals, health centers, etc. ◆ Education system: school classrooms, dormitories and libraries. According to statistics, the number of people who died of air pollution in China in 2003 was as high as 1 10000. 85% of leukemia children's homes were renovated within half a year, and they are still luxuriously decorated. Some women's asthma, lung cancer, leukemia, uterine cancer and breast cancer are all related to air pollution. 1. Indoor harmful gas exceeds the standard 100%. With the assistance of environmental monitoring center, a free indoor air quality testing activity was carried out. Among more than 800 free testing registration calls, the organizer randomly selected 2 1 household for testing, and the results showed that the indoor harmful gas exceeded the standard rate of 100%. Due to the long release period of formaldehyde (3- 15), formaldehyde has become the most over-standard item in this activity, with 2 1 household exceeding the standard to varying degrees. The project that exceeded the standard the least was benzene, with 7 items exceeding the standard. TVOC (Total Volatile Organic Compounds) exceeded the standard seriously, with the highest exceeding standard of 55 times, and 5 households' harmful gases exceeded the standard by 2 digits. Among all the families examined, 6 families all exceeded the standard in 4 major testing items, accounting for 28.6%. According to clinical medical experts, indoor environmental pollution is easy to cause brain hypoxia and damage nerve cells, ranging from dizziness, nausea, limb weakness, sore throat, skin allergy and even death. Formaldehyde and benzene, in particular, are carcinogens and invisible killers in indoor air, which can cause chronic poisoning, affect human hematopoietic function, respiratory system, nervous system and immune system in severe cases, and even cause cell mutation and fetal malformation in severe cases. The pollution inside the car is no less than that in home decoration, and as the weather gets hotter, the pollution will become more and more serious? quot。 The expert warned the driver to be careful of the toxic gas in the car. Experts warned that harmful substances quickly doubled within one hour of car exposure. According to the person in charge of Nanjing Indoor Environment Monitoring and Research Center, plastic floors, adhesives, chemical fiber cloth mats, leather oil and various cleaning agents used in automobile decoration, textiles and plastics used in seats and roofs are the main sources of vehicle air pollution. These materials will release harmful substances such as formaldehyde, benzene and xylene. The smell of carbon monoxide and gasoline produced by automobile engines will reduce the air quality in the compartment. Some of these pollutants may cause cancer, others may affect the nervous system, immune system, endocrine system and reproductive system, causing dizziness, chest tightness, poor respiratory tract, fatigue, cough, sneezing and even hair loss, and pregnant women may also have miscarriage. Not long ago, there was a lawsuit in Beijing, suspecting that new car pollution caused leukemia. Experts say that the pollution in the car is no less harmful than the pollution in the home decoration. The relevant departments in Shenzhen recently conducted random sampling tests on new cars that have been used for less than half a year. The results show that 70% of the cars have excessive concentrations of toxic gases to varying degrees. New cars, especially low-end new cars, at least 60% of the toxic gas concentration in the car will exceed the standard. If the window is closed for a long time, harmful substances such as formaldehyde in the car will exceed the standard by more than five or six times. What worries experts even more is that with the temperature rising, the concentration of harmful gases will increase sharply, especially in summer, if the car is exposed to the sun for more than an hour, the toxic molecules in the car will be extremely active and the pollutants will multiply. Experts from the Jiangsu Provincial Center for Disease Control and Prevention said that in the first six months of driving a new car, it is best not to close the window and keep the car well ventilated; Indoor decoration should be simplified as much as possible, and environmental protection materials should be selected; If you always smell a strong pungent smell of plastic in the car, you should go to the relevant departments to test the air inside the car in time; Old people, children, allergic people, pregnant women, people recovering from serious illness and other susceptible people, if the air inside the car is not purified, try not to take a new car. Solutions to indoor air pollution. The concept of photocatalyst breathing pure air is the dream of every modern person. Due to the development of industrialization, environmental pollution and deterioration are inevitable. After we tried all kinds of methods to purify the air.

Question 7: How to solve air pollution? Where is your industrial zone-how to manage it ~ This polluting enterprise has to pay a lot of extra fees-

Question 8: How to deal with air pollution?

1

Use an air purifier at home.

Home is the place where we stay for the longest time, but outdoor dirty air, dust, decoration pollution, furniture materials, and even pets, the bacteria we bring back will pollute the air at home. How can we purify the air at home? Using an air purifier is a good choice.

2

Form good habits.

(1) You can also raise some green plants at home and place bamboo charcoal package to purify the air; (2) Wash your hands before going home; (3) Do not smoke at home and develop healthy habits; (4) It is also necessary to open the window frequently for ventilation.

three

Outdoor protection.

The air pollution in the outdoor environment should not be underestimated. If you find the weather is gray before going out, remember to wear a dust mask to prevent the pollution of automobile exhaust and dust particles.

four

Drive carefully.

It is skillful to use air conditioning when driving. First of all, when you start the car, you should turn on the car and turn on the air conditioner to circulate outside, so that the air inside the car can circulate with the air outside. Then close the window and adjust the air conditioner to internal circulation. Then change it every once in a while.

In addition, drivers can use car air purifier to purify the air inside their cars and protect their health.
