Description

Indoor air treatment construction process based on real-time monitoring of negative ions
Technical Field
The invention belongs to the technical field of indoor environmental pollution treatment, and particularly relates to a construction process for indoor air treatment based on real-time monitoring and negative ions.
Background
People work and live in the room for 90% of the time, and decoration pollution becomes a killer of human health in the 21 st century. Common indoor air pollutants generated by decoration are: formaldehyde, benzene, and radioactive contaminants of stone, etc. Formaldehyde and benzene are common and serious pollutants. Where benzene and benzene series are released in a relatively short time (typically 6 to 12 months) and the effect of formaldehyde is long-term (studied 3 to 15 years). Therefore, formaldehyde is one of the main pollutants in the indoor decoration process.
In general, people adopt the following methods to remove indoor harmful gases: 1) and (3) strengthening ventilation: this is a common approach. However, harmful substances such as formaldehyde, benzene and the like are hidden in the deep parts of furniture and wall materials, the harmful substances cannot be removed in a short period within a release period of 3-15 years, and once the condition that windows are not suitable to be opened by using a heater or an air conditioner and the like is met, the concentration of indoor harmful gas can rapidly rise, so that the long-term harm is caused to the health of family members; 2) the method for eliminating the plants comprises the following steps: flowers such as chlorophytum comosum, aloe, sansevieria trifasciata and the like are adopted to absorb indoor polluted gas, but the adsorption effect of the plants is very limited, the aim of complete purification cannot be achieved, photosynthesis is carried out in the daytime to absorb carbon dioxide and release oxygen, and the photosynthesis is carried out at night to absorb oxygen and release carbon dioxide, which is not beneficial to human bodies, especially people who are allergic to pollen and flowers; 3) spraying a chemical reagent: chemical agents such as a chemical formaldehyde scavenger, an air freshener and the like cannot be processed cleanly, one gas is used for pressing another gas, the purpose of removing a pollution source is not achieved, and secondary pollution is easily caused by using the chemical agents and is not good for health; 4) activated carbon adsorption method and air purifier: the active carbon can adsorb formaldehyde molecules on the surface of the inner wall of the active carbon through physical adsorption, so that the aim of reducing the formaldehyde content in the air is fulfilled, but the active carbon has limited adsorption capacity and is easy to saturate, and the active carbon is difficult to reuse after about 3-5 months; and the activated carbon absorbs the formaldehyde in small space in the room, and the formaldehyde can be released after the external conditions are changed, so that the environmental protection requirement cannot be met. The air purifier has certain adsorption effect on indoor pollutants such as formaldehyde, has better effect than active carbon, and can remove indoor harmful gases such as formaldehyde, radon gas, benzene, ammonia gas and TVOC and remove peculiar smell. However, the water purifier cannot be completely treated in a short time, the price of the water purifier is relatively high, the service lives of different products are different, the water purifier cannot treat a pollution source, and the effect is greatly limited by the adopted technology and the placing position of the water purifier, so that if only one water purifier is placed in one house, the water purifier only plays a certain role in a room where the water purifier is placed, and the water purifier plays a small role in other rooms;
in addition, the existing indoor air treatment does not have a complete detection process; often, the test is carried out for a period of time, however, the release of formaldehyde is a relatively very slow process, i.e., the test structure is within the standard range during this period of time; after being released for a long time, the release can be higher than the standard range; therefore, a continuous formaldehyde detection and treatment method is necessary.
In a word, the existing indoor air treatment in the same industry has the disadvantages of too simple construction process, unobvious effect, especially peculiar smell removal and serious rebound after treatment.
