ODOR REDUCTION APPARATUS AND ODOR REDUCTION METHOD USING FECL2 FILTER

摘要

The present invention relates to a bad smell reduction apparatus and a bad smell reduction method in a bad smell generating area of a sewage facility, and more specifically, to a bad smell reduction apparatus and a bad smell reduction method which reduce bad smells in a reliable manner by using an iron salt filter capable of removing a main causative material of bad odors generated in a bad smell generating area; are capable of recycling removal media; facilitate maintenance as the iron salt filter is able to link to underwater SOB media; and minimize the electricity rate. In order to achieve the purpose, the present invention provides a bad smell reduction apparatus in a bad smell generating area of a sewage facility, comprising: a bad smell gas treatment bath; an air injection apparatus installed to inject air from the bottom of the water in the bad smell generating area; a bad smell gas reduction unit installed in the bad smell gas treatment bath and reacting with hydrogen sulfide to reduce bad smells; and an iron salt filter including a gas supply/discharge line for guiding bad smell gas in the bad smell gas generating area to the bad smell gas reduction unit, and discharging the deodorized gas.
