ODOR REDUCTION APPARATUS AND ODOR REDUCTION METHOD USING SOB MEDIA IN SEWAGE PURIFICATION EQUIPMENT

摘要

The present invention has the purpose of providing an odor reduction apparatus and an odor reduction method, which basically supply air; oxidize hydrogen sulfide, which is a main cause material of odor, in the air of an odor generating area; and at the same time, oxidize odor substances selectively under water, so as to reduce the odor in a reliable manner; block odor generated in a sewage facility; and facilitate maintenance due to recyclable removal media. In order to achieve the purpose, the present invention provides an odor reduction apparatus in the odor generating area of a sewage facility, which comprises: an air injection apparatus installed to inject air from the bottom of the water in the odor generating area; and an odor gas reduction unit for oxidizing hydrogen sulfide generated in the odor generating area.
