Study On The Release Regularities And Pollution Controlling Of Formaldehyde And TVOCs In Indoor Air

Indoor environment is the people's daily life,work,entertainment,office and study among the most time in contact and residence place.Now,with the improvement of people's living conditions,the growing problem of indoor air pollution.Many types of indoor air pollutants,including formaldehyde and total volatile organic compounds(TVOCs)pollution problem is most common and typical,due to the extensive source of formaldehyde and TVOCs long release cycle,a large degree of influence,has become the indoor air pollution monitoring an important indicator.In this thesis,introduces the research progressof indoor air pollution,and discussed harm to human body.In this paper,the typical indoor air pollutants formaldehyde and TVOCs for the study,and its main source of lblockboard and paint,paint and other materials for the test,through the establishment of simulation chamber,and mainly for specific climatic conditions in Shenyang,regulating different temperatures,fresh air and humidity,according to the experimental study of the release cycle rule and influential factors.Wherein Release of TVOCs study simulated room decoration medium level research.The results reflect the formaldehyde and TVOCs under natural conditions and at different temperatures,the release of the rules and characteristics under the fresh air and humidity conditions,and on this basis,summed up the relative comfort and the best of the human body to reduce the concentration of pollutants in favor of indoor environmental conditions.The study also by HVEF dust sterilization,activated carbon adsorption and photocatalysis set as one of purification technology,the establishment of indoor air pollution air test platform,proved the technology for clean indoor air pollutants such as formaldehyde have good purifying effect,in order to solve the problem of indoor air pollution and provide scientific evidence to support the theory.
