In addition to Wuhan decoration indoor air testing of indoor formaldehyde formaldehyde PM2.5 governance is no longer fresh vocabulary, indoor air pollution has become a focus of attention. Grenada music environmental indoor air pollutants are mainly expressed formaldehyde, benzene, TVOC, ammonia. Data show that indoor air pollution than outdoor pollution 5-10 times, so how indoor air quality affects our health. Formaldehyde irritates the eyes and respiratory tract mucosa, etc; benzene mainly in the rubber, paint, coatings and adhesives, causing symptoms of central nervous system anesthesia, light dizziness, headache, fatigue, severe cases coma may occur; Ammonia is a colorless gas, is often adsorbed on the skin and mucous membranes and conjunctiva, accompanied by headache, dizziness and other symptoms. http://www.green-happy.com indoor air pollution has become a serious hazard to human health and safety "hidden killer", according to experts, "indoor air pollution" has become the "soot pollution" and "photochemical the world's third-largest air pollution "after the pollution problem. Home decoration poisonous known, but the poison came from, but poorly understood, leading to the use of green materials, even if all the decoration of the house is still toxic poisoning. Grenada music environmental company is a member of the China Environment Federation; and has received national indoor environmental purification treatment industry grade construction quality. Excellent professional engineering team, excellent purification treatment technology, advanced equipment, reputable reputation, caring and thoughtful service, effectiveness of governance experience, and make sure once governance, clear air source net, tackling the problem. "Le Gray green" treatment methods currently exist various treatment technologies are their limitations, the use of a single technology in a variety of indoor air pollutants are processed, it is difficult to obtain satisfactory results. Grenada music environmental company focused on a few Advantages kind art, weaknesses integration of resources to form a set of best indoor air pollution control programs also will become one of the important research direction Grenada music environmental company activated carbon adsorption and photocatalytic technology portfolio application, activated carbon adsorption capacity so VOCS concentration to a particular environment, so that it can absorb further intermediate byproducts catalytic oxidation to achieve more complete purification. photocatalytic oxidation combined with ozonation, its synergy with a decomposition of organic pollutants, sterilization and deodorization high purification efficiency of adsorption, catalysis, polymerization ------- Grenada music environmental "clear catalyst technology."
