The purpose of this study is to confirm the removal effect of odorous gas through the multi process. The combination of Scrubber, UV and Adsorption was analyzed using the odor gas of reservoir. Analysis was carried out for six times in total and collection was made once per each process. Sampling was performed in the afternoon during August (1:00 pm~4:00 pm). Multi process has been designed to facilitates the accessories exchange. The advantage is that it facilitates the replacement of the activated carbon and it is convenient to change the type of chemical according to the type of pollution materials. As a result, for odor gas removal efficiency, ammonia 91.8%, trimethylamine 72.0%, hydrogen sulfide 99.9%, methyl mercaptan 99.9% were removed respectively. Removal efficiency of the process is the scrubber (alkali), activated carbon adsorption, scrubber (acid) and UV procedure from the highest order. Further studies on the operating method and efficiency of multi process by the change of wind speed and chemical are recommended.

The mock-up test was carried out to evaluate applicability of unmanned coating method to prevent asbestos scattering from fiber insulation board in same vibration condition of school. Fiber insulation boards were cut into uniform size and attached in checker figure. Bang machine and rubber hammer were used to scatter asbestos sufficiently. Sodium silicate was used as a asbestos scattering inhibitor. The asbestos concentration was counted by PCM (Phase Contrast Microscope) and TEM (Transmission Electron Microscope). Asbestos concentration was 0.014 (1st day) and 0.021 (14th day) f/cm3, respectively in case of without coating. Asbestos concentration was 0.006 (1st day) and 0.008 (14th day) f/cm3, respectively in case of unmanned coating method. It was satisfied the standard of asbestos concentration in indoor air quality management law. So unmanned coating method was applicable to prevent asbestos scattering from fiber insulation board in buildings.
