Description

An indoor volatile organic pollutant, formaldehyde, mites, bird flu virus and atmosphere Comprehensive purification method of particulate matter

technical field

The invention belongs to the technical field of indoor air purification, and in particular relates to a comprehensive treatment method for indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particles.

Background technique

Indoor air pollution comes from decoration pollution and daily life pollution. Formaldehyde, benzene, volatile organic pollutants (VOC) pollution, etc. cannot be eradicated mainly because a large number of artificially synthesized products such as wood-based panels, foam plastics, and Mixtures, etc., resulting in the continuous release of harmful substances, and the formation of a superimposed effect, even if the real environmental protection product materials are excessively used in a small indoor space, resulting in exceeding the standard. The pollution caused by atmospheric particulate matter in people's daily activities is even more inevitable. Some developed countries in Europe and the United States have an early understanding of the impact of gases released from building materials on indoor air and the degree of harm to human health.

Using the method of sticking transparent tape, the college students were inspected for facial mite infection, and their hygiene habits, living environment and facial diseases were investigated by questionnaire. The results showed that the mite infection rate was 13.29%. The infection rate of follicular mites was significantly higher than that of sebaceous mite, and the mixed skin infection rate was higher. The way of cleaning the face had a significant impact on the infection rate; gender, place of origin and living environment had no significant impact on the infection rate. Conclusion Mite infection is common in the population. Hygienic habits and skin types are related to the infection rate. Publicity and prevention should be strengthened.

At present, the indoor volatile organic pollution, formaldehyde and other treatment solutions on the market can be said to be varied, and it is difficult to distinguish between true and false. The simplest is the plant flavor method, followed by adsorbents such as activated carbon, negative ion air purifiers, photocatalyst deodorization methods, and so on. Plants are natural products, and the absorption of formaldehyde by plants is the simplest and environmentally friendly removal method, but the removal speed is slow and it takes a long time. Bamboo charcoal and activated carbon all use the principle of carbon to absorb odors and harmful gases to control indoor air pollution. It is a treatment method with low cost and no side effects. But the removal rate is low, and its removal effect on formaldehyde is about 50%. Negative ion air purifiers use an instrument that generates high-voltage electricity to ionize and decompose harmful gases, so that harmful gases such as benzene and formaldehyde are quickly oxidized into negative ions, which are reduced to oxygen, water and carbon dioxide after combining with air. However, the life of negative ions is very short, and the removal effect is not obvious. The removal effect of this kind of method on formaldehyde is about 70%. Photocatalysts can only react when there is light, which may cause slight secondary pollution and affect the painted surface of walls, paper, and wooden furniture. This type of scavenger has a removal effect of about 70% on formaldehyde. At present, the air purification technology of air purifiers mostly stays in adsorption and filtration. Even if high-efficiency catalytic technology is used, it can only be passive adsorption, and the killing effect on formaldehyde, benzene series, VOC and mites in the gas phase and particle phase of space air is not obvious. .

The market will show a positive attitude towards air pollutants in automobiles and housing, and with the introduction of standards such as "Guidelines for the Evaluation of Air Quality in Passenger Cars" and "Indoor Air Quality Standards", people's understanding of formaldehyde has become legal. Recognition, with legal support and basis, from the detection of air hazards to the removal of harmful substances will have good expected results.

As a broad-spectrum bactericidal disinfectant, there are many reports on chlorine dioxide (ClO ₂ , chlorine dioxide), mainly about the preparation and standard detection methods and oxidation mechanism of chlorine dioxide liquid or solid, and chlorine dioxide liquid or solid The effect and mechanism of killing surface bacteria. It is reported that chlorine dioxide liquid or solid has a good killing effect on various pathogenic bacteria such as Escherichia coli, Legionella, mold, anthrax, etc. Chlorine dioxide liquid or solid The inactivation effect and mechanism of various viruses such as hepatitis A and influenza. Chlorine dioxide liquid or solid is used in water treatment and disinfection. Chlorine dioxide liquid or solid is used in medical treatment and medical equipment disinfection. Chlorine dioxide liquid or solid is applied It is used in the treatment of environmental sewage and feces, the application and mechanism of chlorine dioxide liquid or solid in the antiseptic preservation of food and its packaging materials, the application and mechanism of chlorine dioxide liquid or solid in air disinfection, and the application of chlorine dioxide liquid or solid in air disinfection. Chlorine gas has only been reported to be used in water treatment and food preservation, and the bactericidal effect of chlorine dioxide gas.

Chlorine dioxide liquid and chlorine dioxide gas are used to kill acarids and there is no report, and there is no report on the measures to prevent the transmission of acarids from the human body that has been infected with acarids.

At present, no one has studied the comprehensive treatment method of indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particles by using chlorine dioxide gas combined with polymer materials.
