Indoor Environment Assessment And The Measures Study On The Pollution Control

As the development of the social economy and the residential fitment, the comfortable indoor environment becomes people's intensive requirement, and the level of indoor decoration increases higher and higher. So the indoor environment pollutants caused by fitment have become more seriously. People are paying more attention to the polluted problem.Three teacher's condoes and two offices were selected as the sample points. Formaldehyde, total volatile organic compounds, respirable particulate matter, sulfur dioxide and so on, which are harmful to the human health, were analysised and evaluated. In the sample points, subjective questionnaire survey and site detection were investigated in one year. Some control measures to those pollutants were provided in the end.Firstly, the subjective questionnaire survey was adopted on the room staff and the external staff. Secondly, the data were analyzed and the main sources and the degree of the pollutants were gotten. Using Gas Chromatography Aglient 6890-Mass Spectrum 5973 and Agilent 6820 chromatography, the organic composition, contents and sources of the particular matter were obtained by utilizing qualitative and quantitative analysis. Then the indoor environment pollutants were assessed by using the fuzzy clustering comprehensive mathematical model. The indoor environment quality grade of sample points was gained by combining with the subjective results and the pollutant degree was obtained. Finally, the pollution prevent and control measures were corresponded in view of the sources of the pollution.The pollutants of the sample points were detected by using advanced experimental apparatus. The tested data were analyzed and assessed by adopting an appropriate evaluation method. A basis and reference were proposed for the assessment of indoor environmental quality in the future.
