The Study About Benzene Series( Benzene, Toluene, Xylene) Pollution Characteristics After Decorating Indoor

At present, in many cause indoor air pollution of volatile organic gas, formaldehyde and benzene series pollution is the main aspect of indoor pollution. In recent years, more and more people understanding of indoor formaldehyde, also more and more attention, while less attention on benzene series pollution. So urgently needed to indoor benzene series pollution sources and release of laws, influencing factors and control scheme of in-depth study.Research idea of this paper are as follows: indoor benzene series pollution present situation analysis, indoor release of benzene series rules and influence factors of research-indoor benzene content control method contrast, indoor benzene content control scheme.First of all, using the method of literature, this paper summarizes the nature of the benzene content, harm, source, release regularity and control methods. In shijiazhuang city in the past two years new building indoor decorate a total of 100 benzene content data statistics and analyses, track, and the part of the house was concluded that shijiazhuang new decorate building heavy benzene in indoor air release rule and influence factors. Tracking test results analysis showed that:1) in 100 samples of new decoration residence, benzene content exceeds bid is not very common, benzene, toluene, xylene which are 3%, 14% and 3% respectively, but as a result of benzene series matter to human body harm is serious, still respond to its attention;2) the benzene in indoor air after decorating department showed a trend of gradual decline over time, initial concentration and no release sex for a long time, generally 3 months can release completely;3) as the change of temperature, release rate and temperature of the benzene and benzene series revealed a positive phase correlation change rule;4) indoor decoration materials load is benzene content one of the determinants of pollutant distribution rate;5) enhance the air circulation can be accelerated to a certain extent, the release of benzene content, fulfillment only to a certain extent, but its role, not flow is bigger, the better;By case and experiment contrast method, this paper puts forward indoor decoration for residents in shijiazhuang benzene series pollution control plan:1) the economy: the air circulation method and green plant method combined control;2) effect type: air flow, air purifier, green plants and activated carbon adsorption method combined control; 3) affordable: the air circulation, green plants and activated carbon adsorption method combined control.
