Air pollution control, what is air pollution control

Air pollution control measures include: the implementation of green power dispatch, key industrial enterprises to limit production and pollution or stop production, strengthen road cleaning, key vehicles are banned, fireworks and firecrackers are prohibited, reform the energy structure, control pollutant emissions, afforestation, etc.

Air pollution, also known as air pollution, refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, showing sufficient concentrations and reaching sufficient time, and thus endangering human health and the environment.

Air pollution is caused by air pollutants that exist in sufficient amount, nature and time to affect human beings or other living beings or property.

The types of air pollution can be divided into reduced pollution, oxidative pollution, petroleum pollution, and other special pollution according to different chemical and physical properties.

Formaldehyde, TVOC, benzene, ammonia, radon. Among them, formaldehyde is the most extensive, and the glue, paint, board furniture, and fabric used in the decoration process are all produced by formaldehyde.

After the decoration of new houses, the average check-in time in the country is 2-3 months later, and the main reason is the problem of decoration pollution, including not only taste, but also formaldehyde, radon and other colorless and odorless harmful substances.

There are also a few ways to remove it:

1. Ventilation is the universal law, to ensure a long time of ventilation, and at the same time it is best to ensure high temperature and high humidity.

2. Aldehyde removal spray: select some high-quality photophyll that decomposes the source of formaldehyde pollution to achieve the effect of removing decomposition. This section has no requirements for light and ultraviolet rays, and will not decompose incompletely.

3. Ye Guang mud, activated carbon. This kind of formaldehyde can be physically adsorbed, but activated carbon has the problem of easy saturation and frequent replacement. Ye Guangni is more trouble-free, has stronger adsorption, and can also decompose adsorbates without secondary release.

4. Green plants and flowers. Theoretically, it is effective for the removal of aldehydes. However, it cannot remove aldehydes in large quantities and quickly, so it is mainly used for landscaping the indoor environment.

5. Air purifier. This is not as good as ventilation in terms of aldehyde removal effect, and I personally feel that it is not very necessary.

Above, choose the removal method according to your actual situation, and move into a new home after it is safe.

Newly renovated houses may contain large amounts of formaldehyde, which can damage human health and cause more serious health problems such as respiratory diseases, cancer, and even leukemia. Therefore, after the decoration of the new house, it is necessary to carry out indoor air treatment to prevent serious harm to the body due to the decoration pollution of the new house. The following summarizes several scientific methods to remove formaldehyde, hoping to help newly renovated friends.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Green plants, aloe vera, cactus, pothos and other plants have a certain absorption capacity for formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde.

3. Ye Guangni is a new generation of air purification products, which are mainly used to eliminate formaldehyde, benzene, radon, TOVC and other harmful gases released by interior decoration materials and various items.

4. Under certain conditions, the formaldehyde scavenger reacts with formaldehyde to generate other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

5. The fresh air system is a system that filters the outdoor air and transports it to the room through the pipeline, and discharges the harmful substances contained in the room from the corresponding pipeline.

6. Professional formaldehyde removal companies can also quickly remove indoor formaldehyde and harmful substances, but because China's indoor air purification industry started late, there are no particularly strict scientific specifications, in the formaldehyde removal company, there are many unprofessional and irresponsible companies, we must keep our eyes open when choosing.

Air pollution, also known as atmospheric pollution, generally refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present sufficient concentrations, reach sufficient time, and thus endanger the comfort, health and welfare of the human body or the environment.

Air pollution control is the measures and means to control harmful substances and harmful pollution in the air through some natural or artificial technical means.

Air pollution control is mainly aimed at the indicators of air pollution and measures to limit emissions.

At present, air pollution, corresponding to air quality factors, mainly includes sulfur dioxide, nitrogen oxides, ozone, PM, and PM ten.

Therefore, the corresponding air pollution control is a measure to limit emissions mainly for the factors related to these air quality.

1.Opening windows for ventilation can remove formaldehyde.

2.Plants have a certain absorption capacity for formaldehyde.

3.Formaldehyde scavengers can react chemically with formaldehyde.

Air pollution controlThe content is very rich, comprehensive and systematic, involving many aspects such as environmental planning and management, energy utilization, pollution prevention and control, etc. Due to the different characteristics and conditions of air pollution in different regions (or cities), as well as the direction and focus of comprehensive air pollution prevention and control, it is difficult to find comprehensive prevention and control measures suitable for all situations, so it is necessary to put forward corresponding countermeasures according to local conditions.

The atmospheric environment refers to the physical, chemical, and biological properties of the air on which living organisms depend. Harmful gases such as ammonia, sulfur dioxide, carbon monoxide, nitride and fluoride emitted by human life or industrial and agricultural production can change the composition of the original air, cause pollution, cause global climate change, and destroy the ecological balance.

Aerosol contaminantsIn atmospheric pollution, aerosols refer to solid and liquid particles in the air, or suspended bodies of solid and liquid particles in a gaseous medium. According to the ** and physical properties of aerosols, they can be divided into dust, smoke, fly ash, black smoke and fog.

The prevention and control method of air pollution is a scientific and technological method for the prevention and comprehensive treatment of air pollutants or secondary pollutants transformed by them.

The atmospheric environment is a whole, and it has become the basic way to comprehensively prevent and control air pollution in a certain area by unifying the planning of energy structure, industrial development and urban construction layout, comprehensively using various prevention and control technical measures, and making full use of environmental self-purification capacity in order to improve environmental quality.

Ways to combat air pollution:

1. Reduce pollution emissions.

Reform the energy structure, use more non-polluting energy sources (such as solar energy, wind energy, hydropower) and low-pollution energy (such as natural gas), pretreatment of fuels (such as desulfurization before coal burning), and improve combustion technology can reduce emissions.

In addition, before the pollutants enter the atmosphere, the use of dust and smoke removal technology, condensation technology, liquid absorption technology, treatment technology, etc. to eliminate some pollutants in the exhaust gas can reduce the number of pollutants entering the atmosphere. Plant purification method, China's use of plant source disinfection and sterilization has a history of more than 3,000 years.

2. Self-cleaning ability.

Different meteorological conditions will have different capacities for pollutants in the atmosphere, and the same amount of pollutants will be discharged, resulting in different concentrations of pollutants. For areas and time periods with strong winds, good ventilation, turbulence and strong convection, the atmospheric diffusion and dilution capacity is strong, and more factory and mining enterprise activities can be accepted.

In areas and time periods of temperature inversion, the diffusion and dilution ability of the atmosphere is weak, and more pollutants cannot be accepted, otherwise it will cause serious air pollution. Therefore, emissions should be effectively controlled in different regions and at different times.

3. Industrial Zone.

The selection of the site, the design of the chimney, and the planning of the urban and industrial areas should be reasonable, so as not to concentrate the atmosphere excessively, and not to cause repeated and superimposed pollution, resulting in serious pollution incidents in local areas.

4. Afforestation.

Dense forests can reduce wind speed, allowing large particles of dust carried in the air to fall. The surface of the leaves is rough and uneven, some have fluff, and some can secrete mucus and oil, so they can absorb a lot of dust. Dusty leaves can continue to absorb dust after being washed by rainwater.

In this way, the reciprocating blocking and adsorption of dust can purify the air.

5. Change the fuel composition.

Implement the conversion from coal to gas. At the same time, we will step up research and open up other new energy sources, such as solar energy, hydrogen fuel, geothermal, etc. This can also greatly reduce the pollution of soot.

6. Start with yourself.

Don't litter; Take buses and subways as much as possible to travel, and reduce the use of private cars; Participate in greening activities such as tree planting; Private cars are equipped with exhaust gas treatment devices and lubricating oil is used to fully burn fuel and reduce harmful gas emissions.
