Which indoor air pollution control company is good?

The working principle of the air purifier is to actively adsorb harmful substances and finally decompose the pollutants in the air (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.) into water and carbon dioxide, which can effectively improve the cleanliness of indoor air. It takes 20 minutes for the effect of purifying the air in the room, and the formaldehyde pollution concentration is reduced from the initial milligram cubic meter to the national standard milligram cubic meter, and when it reaches 1 hour, the internal formaldehyde concentration is milligram cubic meter.

Barrett Fresh Air System The fresh air system can make the aerobic air enter the room continuously and evenly, and at the same time add enough fresh air to the room, and discharge the dirty air in the room to the outside after heating. The fresh air is sent into the room after entering the high-efficiency heater through the filter to ensure that the temperature does not drop. Due to the heat, it has a relatively economical operating cost and low power consumption.

In addition, sound insulation, dust-free, cleanliness and so on are also the unique advantages of the fresh air system. The purification time is between 15-20 minutes, and the air pollution concentration in the room using the fresh air system is just reduced to the limit value of milligrams and cubic meters in the national standard.

Indoor air treatment, Guangzhou Yousu Environmental Protection Technology has done a good job.

In China, the indoor air treatment industry is widely distributed, mainly including air purifiers, fresh air systems, air testing instruments, formaldehyde removal products, air purification services, etc. Among them, the rolling plexus air purifier is the most common indoor air treatment equipment, and its sales and use are also the largest. The fresh air system is a kind of equipment that enters the room through the outdoor fresh air and discharges the indoor dirty air, which is widely used in high-rise buildings, commercial offices and other fields.

Air testing instruments are equipment used to detect indoor air quality, mainly including VOC detectors, detectors, etc. Formaldehyde removal products are a kind of products that remove indoor formaldehyde through adsorption, decomposition, etc., and are widely used in newly renovated houses. Air purification service is an industry that provides indoor air treatment services, which mainly includes indoor air testing, air purifier installation, air purifier maintenance and other services.

In general, China's indoor air treatment industry is widely distributed, and different equipment and service forms have their own unique application scenarios and advantages.

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.

The content of air pollution prevention and control is very rich, comprehensive and systematic, involving many aspects such as environmental planning and management, energy utilization, and pollution prevention and control. 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.

The atmospheric environment is closely related to human survival, almost every factor of the atmospheric environment can affect human beings, after all, human beings cannot exist independently from the atmospheric environment, and the quality of the atmospheric environment is a powerful guarantee for human health activities. Therefore, we must implement sustainable development, pay attention to people's livelihood, increase the control of air pollution, and give people a new environment with birds and flowers and fresh air.

I will provide you with a few old companies that do environmental pollution control, they have been doing this industry for many years, and their reputation is absolutely guaranteed, one is native titanium, and there are no thieves and sunshine factors in the world, you can compare them to see which one is more suitable for you.

The sharing economy enables individuals to participate in socialized production, promotes the rise of the individual economy with entrepreneurs as the main body, and forms an effective promotion of mass entrepreneurship and innovation.

China's population participating in the sharing economy is huge, but there is a significant gap in the proportion of the total population, and the penetration rate needs to be improved

1. In terms of the size of the population participating in the sharing economy, China is twice that of the United Kingdom and the United States combined, with a total scale of more than 300 million people.

2. In terms of the proportion of participants in the sharing economy in the total population, China is only 22%, which is lower than the United Kingdom and the United States, and far less than Canada's 39%.

Not! Not yet, but there are many listed companies that pollute the air.

Indoor air pollution control methods.

1) Treatment with chemical methods such as decoration deodorizer and formaldehyde scavenger: the advantage of this method is that the cost is relatively low, and the removal effect of a single pollutant substance is good. The disadvantage is that the treatment is not thorough enough, such as formaldehyde scavengers, p-benzene and benzene series, and VOCs cannot play a role.

And the scope of use is limited. At present, there are brands such as Grevekang, Aldehyde Wuying, Juankang and other brands on the market, all of which belong to this type of products. In the past, some local methods used by consumers, such as vinegar absorption, tea absorption, etc., were similar to this principle, but the effect was much worse than these chemical products.

As for the practice of masking with some fragrances, its effect is even more minimal.

2) Photocatalyst: This method has recently been introduced from abroad and is widely used, and it has the significant characteristics of quick treatment and effective treatment of heavy pollution, but it is also high. The photocatalyst is catalyzed by ultraviolet rays to produce free electrons and holes, and then produce reactive oxygen species and hydrogen and oxygen radicals with strong oxidizing effect, which can oxidize harmful substances in the air into carbon dioxide and water.

The removal effect of this type of scavenger on formaldehyde is about 70, and the removal effect of benzene and TVOC is more than 80.

3) Ozone: Ozone is a strong oxidizing property and is an internationally recognized common and safe physical treatment method, suitable for moderate and light pollution. Its biggest feature is that it does not produce any residue and secondary pollution.

However, when using this technology, the person should temporarily leave the room to avoid poisoning. Its removal effect on formaldehyde is about 40, the removal effect of benzene is more than 90, and the removal effect of TVOC is about 50.

4) Bamboo charcoal: The porosity and large specific surface area of bamboo charcoal determine that it has a strong adsorption capacity. It can adsorb harmful substances such as formaldehyde, benzene, TVOC and sulfur dioxide released by indoor wood-based panels, coatings, paints, adhesives, insect repellents, etc., and can also release negative ions and minerals, with strong humidity regulation performance.

It has been proved by a number of experiments at home and abroad that its removal effect on formaldehyde is about 50, the removal effect of benzene is more than 90, and the removal effect of TVOC is about 50, and its powerful function in removing formaldehyde, benzene, ammonia, TVOC and other harmful gases in the air is significantly better than other so-called high-tech products. It is low-cost, non-toxic***, but it is slow to work and needs to be replaced frequently. This method can be used as a long-term treatment method for slightly excessive indoor air pollution.

5) Other methods: pure plant-based scavengers extracted from plants are natural products, which will not cause secondary pollution to the environment, and are ideal air pollution fresheners. Plants that have been proven to have a controlling effect on indoor air pollution are:

1.Plants that have the effect of absorbing formaldehyde, such as spider plant, aloe vera, agave, tiger tail orchid, etc.; 2.Plants that have the effect of absorbing benzene, such as ivy, iron tree, etc.; 3.

Plants that have the effect of absorbing trichloroethylene, such as evergreen, daisy, agave, etc.; 4.Plants that have the effect of absorbing sulfur dioxide, such as moon, rose, etc.; 5.plants that have a vacuuming effect, such as osmanthus; 6.

Plants with bactericidal properties, such as mint.

It is effective, but you need to choose a good company, good product quality, I hope it will help you, and the treatment of the environment can reduce the harm and load on your body, and it will be good for your liver organs, and it will not cause various respiratory diseases and cancer.

A lot of it is now advertising and publicity.

In fact, the power of indoor pollution depends first on the source of pollution.

The best way to deal with it is to make a ventilation system.

Many of the products on the market now have a certain effect.

However, the overall purification effect is still poor.

There are by-products produced.

It is easy to cause secondary pollution.

At the moment, there is no better way to control indoor air pollution, but it must be a promising industry.

Indoor air pollution control should be divided into situations.

If the source of pollution is indoors (household pollution is more serious than outdoor pollution), indoor air pollution should be treated by opening windows for ventilation, air purifiers, etc.

If the source of pollution is outdoors (outdoor pollution is more serious than household pollution), such as outdoor haze intrusion, etc., it should be treated from the doors and windows, and energy-saving doors and windows with good sealing, such as Meidun temperature screen, and equipped with a fresh air system, such as five nets and four micro-systems, to isolate haze and outdoor air pollution.

If it is not a newly renovated house, choose suitable energy-saving doors and windows, and then adjust the indoor air quality through the fresh air system, or add green plants to purify the indoor air.
