DEODORIZATION SYSTEM BY NOVEL STRUCTURED BIOFILTER USING SEPARATELY INCUBATED BIOAEROSOL ORIGINATED FROM FOOD WASTE COMPOSTING PROCESS AND FILTRATION DEVICE THEREFOR

摘要

An offensive odor purification and barnyard manure manufacture system and a cultivating filter device used to the same are provided to integrate the purification device with high efficiency into the energy recovery type ventilation unit. A cultivating filter device(20) has a main path, a differential mobility separator, a first branch pipe, a second branch pipe, a bulk filter, and a cultivating filer. The main path passes an offensive odor gas and a bioaerosol generated from a composting device(10). The differential mobility separator separates a certain bioaerosol from the bioaerosol passing through the main path. The first branch pipe passes the bioaerosol separated by the differential mobility separator. The second branch pipe passes a bioaerosol which is not separated by the differential mobility separator. The bulk filter is mounted in the second branch pipe. A plurality of media for cultivating the bioaerosol passing through the first branch pipe are installed in the cultivating filer by multi-stages. The cultivating filer is installed so that the bioaerosol passing through the bulk filter mounted in the second branch pipe is passed through the media installed by the multi-stages. A dehumidifying device(40) removes the offensive odor gas passing through the cultivating filter device and moisture contained in the bioaerosol. A barrier plasma device deodorizes the offensive odor gas and the bioaerosol passing through the dehumidifying device. A catalyst device performs an absorption and catalyst reaction to remove harmful residual materials generated by the barrier plasma device. A heat exchanging device(50) exchanges heat with the air passing through the catalyst device, and supplies the heat-exchanged air to the composting device again.
