Emission reduction, collection and processing method for trough-type aerobic composting odors

The invention discloses an emission reduction, collection and processing method for trough-type aerobic composting odors. The method comprises the steps that composting raw materials are added to composting troughs, and odors produced by the composting troughs are collected by a gas collecting hood under the sheltering of a roller shutter, are led into a wind pipe through a draught fan, enter a cyclone dust remover so as to be subjected to dust removal, enter a deodorization tower and then enter a biofilter after the odors are processed by the deodorization tower. The method disclosed by the invention has the advantages that the odor emission can be effectively reduced, and the composting efficiency can be increased; and odor ingredients can be better collected and removed in an open aerobic composting environment.
