How to disinfect indoor air? What are the methods of indoor air disinfection?

The preferred way to disinfect indoor air is to use disinfectant solution to spray in the room first, and then seal the room for 10-30 minutes. Finally, open the doors and windows and ventilate. It is indeed a bit troublesome to do this, but it is also much more convenient to operate directly by using equipment such as air disinfection and disinfection purifiers, air purifiers, and air environment machines.

But in any case, the main method of indoor air disinfection is to maintain the flow of air, that is, to allow the indoor air to exchange with the outdoor fresh air in a timely manner.

The right way to disinfect the room.

1. Natural ventilation.

Regularly opening doors and windows for natural ventilation can effectively reduce the number of microorganisms in the indoor air, improve indoor air quality, and adjust the microclimate of the room, which is the simplest and most effective method of indoor air disinfection. The natural ventilation effect is affected by whether the ventilation of the room is good and the outdoor air quality, the room is well ventilated, the outdoor air is fresh, and the ventilation effect is good.

2. Bleaching powder disinfection method.

Bleaching powder can inactivate enzymes in bacteria, causing them to die. Use 1 to 3 pieces of bleach supernatant on tables, chairs, and floors.

3. Vinegar disinfection method.

Vinegar contains acetic acid, which has a certain sterilization ability and is often used for indoor air disinfection. For a room of 10 square meters, you can use 100 to 150 grams of vinegar, dilute it with water 2 times, put it in a bowl and simmer it, and close the doors and windows when smoking.

4. Spraying and fumigation of disinfectants.

The irradiation ——— of ultraviolet lamp can be fixed irradiation, can also be mobile irradiation, indoor according to the ultraviolet lamp power of 1, irradiation 30 60 minutes, has a good disinfection effect. The circulating air ultraviolet air sterilizer composed of high-intensity ultraviolet lamp and filtration system also has a good disinfection effect, and can be turned on for 30 minutes when used, and then turned on after a certain period of time; It can also be continuously turned on for disinfection. Ultraviolet radiation has a certain amount of damage to people's eyes.

The air disinfection ozone generator has the functions of air disinfection, sterilization, odor removal, and air purification, and has many advantages such as no dead ends, no secondary pollution, and no toxic by-products.

The ozone generator can be used for air disinfection, water disinfection, sewage treatment, object surface disinfection, cash disinfection, fruit and vegetable preservative, pipeline cleaning and disinfection, waste gas treatment, flue gas desulfurization and denitrification.

The air disinfection ozone generator is plug-and-play and supports unattended operation! The whole machine has a compact structure, a small footprint and low operating costs.

Open windows frequently and ventilate more often as the first step in fighting germs. Flowing air dilutes local levels of viruses and bacteria and also helps to renew indoor air.

It is also necessary to master the correct method of opening windows for ventilation. First of all, ventilate at least 2-3 times a day, and open the window in the absence of wind or light wind, it is recommended to open the window for 20-30 minutes. If you only open a small slit for ventilation, the window opening time should be 30-60 minutes.

Secondly, the weather is cold at present, and you can choose a time period with a higher temperature when opening the window for ventilation, such as 11:00-16:00 every day, and you should also pay attention to keeping warm.

Second, wash your hands frequently. Hand washing is an important means of preventing the spread of disease, and it is important to wash your hands as soon as possible when you are home from going out or if your hands are contaminated, rinse with running water and hand sanitizer, or disinfect with alcohol-based disinfectant.

There is no need for special disinfection of clothes coming back from going out, we can take cleaning, drying and other ways to dispose of them. Do a good job of household hygiene. Household cleanliness and hygiene are very important.

Indoor disinfection? Just keep it ventilated! As long as you keep ventilation, SARS and swine flu are not afraid, what kind of poison do you have?

If there are items used by the patient, they can be disinfected with high temperature or disinfectant. If you still don't feel at ease, consider whether it is your heart. Take it easy!

At present, the most cutting-edge technology of air disinfection is the hydroxyl radical generator, the products of which are carbon dioxide and water, and will not produce secondary pollution!

It can also disinfect surfaces!

Ordinary disinfection methods:

01.Air purifier: It is a mechanical ventilation device with a bacterial removal rate of only 24%.

02.Ultraviolet antivirus: Excessive exposure to ultraviolet rays of the sun can cause damage to the human body's **, eyes and immune system.

03.Ozone disinfection: ozone is a first-class gas at room temperature, with poor stability, and can only be produced on site and used immediately. And it must be disinfected unmanned, and at least 30 minutes after disinfection can be entered.

Room air disinfection:

First of all, you can mash mugwort leaves or cangshu, put them in a glass container and light them, or light sandalwood directly. The use of smoke to achieve the effect of air disinfection;

Secondly, vinegar or peracetic acid is poured into a glass container, and heating and vaporization can have a disinfection effect;

Finally, a 30W ultraviolet lamp can be installed indoors, and the light source irradiation has the effect of destroying bacteria.

What can be done to improve indoor air quality:

1.First of all, when cooking in the kitchen, whether it is cooking rice or boiling water, it is necessary to open the window and range hood, which can not only suck the smoke out of the room, reduce kitchen pollutants, but also make the kitchen air drier, thereby inhibiting the growth of bacteria.

2.Secondly, when using the toilet in the bathroom, the lid should be closed and then flushed to prevent the pollutants of the toilet from falling into the indoor air with the flush force and contaminating the sanitary ware, thereby polluting the air in the bathroom. In addition, the toilet tank can be disinfected with a solid disinfectant.

3.Then if you use an air conditioner indoors, it is best to use it with a ventilator, which can quickly cool the outdoor hot air and make the indoor air fresh. Or add an air purifier to break down the dust and odors in the air and make the air cleaner.

4.Finally, every time you clean indoors, it is best to use a vacuum cleaner, or use a wet mop to wipe the floor, and when sweeping the floor with a broom, the action should be light to avoid dust flying up and polluting the indoor air. It is also not recommended to use carpets and feather dusters", otherwise the lint will fly everywhere.

Ventilation and keeping the room clean.

An effective way to reduce the density of microorganisms in the room is to inject fresh air into the room at regular intervals, that is, to open windows for ventilation. It has been reported that when the indoor air is circulated to the outside world, the microorganisms in the air can be reduced in the first 30 minutes, within 75 minutes, and after 140 minutes, there are basically no bacteria, indicating that ventilation is a very simple and effective way to purify indoor air. In the hot summer, the high temperature is unbearable, the air is thin, and the convection is poor, so attention should be paid to opening doors and windows frequently for ventilation; In winter, the climate is cold and the room temperature is low, so you can keep ventilation twice a day for 20 to 30 minutes each time.

In addition, maintaining cleanliness in the room can reduce the amount and flow of indoor dust, and can also reduce the amount of microorganisms in the air.

Use an ionizer to purify the air.

Turn on the negative ion generator, and use the electric field generated by it to adsorb the inductively charged dust and suspended microbial particles in the air to achieve fresh and purified air.

Spray and fumigation.

Chlorine-containing disinfectants, peracetic acid, glutaraldehyde, chlorine dioxide, etc. can be used for air spraying and fumigation.

The concentration of chlorine-containing disinfectant (containing available chlorine) for air spray disinfection is 400 800 ppm; For fumigation, aldehyde chloride mixture (paraformaldehyde dry powder: euchlorine 24:76), the dosage is 3 grams m3, and the relative humidity is greater than 70%, ignition and closing the doors and windows for 1 hour; Or use acid chlorine fumigant to ignite fumigation, the dosage is g m3, the relative humidity is greater than 70%, and the doors and windows are closed for 1 hour.

The concentration of air spray disinfection with peracetic acid is g3 for 1 hour, and the relative humidity should be 60% 80%; During fumigation and disinfection, 3% 5% peracetic acid solution can be used for heating and fumigation, the dosage is calculated as 1 3 grams m3, the sealing effect is 1 hour, and the relative humidity is greater than 60%; If there is no heating condition, 16% 20% peracetic acid solution can be used for natural volatilization, and the dosage is 1 3 g m3 and the action time is 1 2 hours. Adding 20% 70% ethanol or isopropanol to peracetic acid can significantly enhance its disinfection effect. The residual odor of peracetic acid can be neutralized with a 5% sodium thiosulfate solution.

It is still necessary to ventilate and wash hands frequently. Whether it's after disinfecting clothes or wiping and spraying furniture with disinfectant, the most important thing is to ventilate and wash your hands. Usually when you go out, you can use cloud killing air sterilization liquid to effectively sterilize, and you can spray disinfection outside to avoid cross-infection, this is a chlorine-containing formula, which can be used by mothers and infants, and it is very safe after the elimination number certification.

How to disinfect the air at home.

Open windows for ventilation and disinfection, and open doors and windows for half an hour of ventilation before going to bed, which can effectively reduce the indoor virus content; Fumigation and disinfection, put vinegar or peracetic acid into the pot, add water and heat it with an induction cooker, and the liquid vaporizes into the air to have a disinfection effect; Ultraviolet lamp irradiation disinfection, using the sterilization function of ultraviolet light, irradiation for more than 1 hour can kill indoor air microorganisms.

2. What should be paid attention to in indoor air disinfection?

There are many ways to disinfect indoor air, including ozone disinfection, ultraviolet disinfection, alcohol disinfection, and 84 disinfection, and the effect of each disinfection method is good, but no matter which disinfection method is chosen, it is necessary to do a good job of related work, otherwise it is easy to have many problems. For example, if you use ozone for disinfection, you need to pay attention to the concentration of ozone, which is too high and is not good for the human body, and it takes at least half an hour to enter after disinfection.

The ultraviolet lamp irradiation disinfection is also noteworthy, the ultraviolet lamp will produce ultraviolet rays, ozone, etc. when working, and the disinfection effect is better, but the doors and windows need to be closed to ensure the disinfection effect, and people must not be on site during the disinfection period. If you use alcohol for disinfection, you should pay attention to high temperature and open flame.
