NOVELTY - The apparatus comprises a reactor discharging the cycling gas and fetor production material, a filter layer arranged at an inner side of the reactor to perform an organic acid fermentation process, a blower section arranged at an outer side of the reactor to circulate the cycling gas, a steam separator equipped in the outer side of the reactor and separating the organic acid and condensed water, a filtered water exhausting part passing the filtered water through the filter layer, and a sludge storage part storing the sludge and blocking the sludge from pass through the filter layer.    USE - The apparatus is useful for removing odor (claimed) generated from a pollution source e.g. sewage, effluent, leachate or livestock excretions effluent.    ADVANTAGE - The apparatus can block the odor generation by removing the odor accompanied in a pollution source and can effectively remove the odor.    DETAILED DESCRIPTION - The apparatus comprises a reactor discharging the cycling gas and fetor production material, a filter layer arranged at an inner side of the reactor to perform an organic acid fermentation process, a blower section arranged at an outer side of the reactor to circulate the cycling gas, a steam separator equipped in the outer side of the reactor and separating the organic acid and condensed water, a filtered water exhausting part passing the filtered water through the filter layer, and a sludge storage part storing the sludge and blocking the sludge from pass through the filter layer. The blower section circulates the cycling through a first flow pipe and a second flow pipe, where the first flow pipe guides the flow of the cycling gas from the reactor to the steam separator and the second flow pipe guides the flow of cycling gas from the steam separator to the reactor. A gas outlet is equipped in an upper portion of the steam separator to discharge the cycling gas. A condensate drain part is arranged at a side of the steam separator to discharge the organic acid. A coolant jacket is arranged in a lower side of the steam separator for condensing the moisture. A first filtration part is arranged in a side part of the reactor and a second filtration part is provided at a lower part of the reactor. The filter layer has an open-cell (cell) structure of 50-200 mu m. A heating system is equipped in the reactor. A sewer pipe ejects the sludge from the sludge storage part or the filtered water ejected from the filtered water exhausting part. A digestion tank includes a dehydrator to dehydrate the sludge. An outlet line ejects the fetor production material or sludge from the digestion tank to the reactor. An organic acid and water outlet pipe inflows the organic acid and condensed water condensed in the steam separator to the digestion tank. A water level sensor senses an inner portion water level of the reactor and controls an amount of the sludge ejected from the sludge storage part based on the water level recognized in the water level sensor. A capture site samples the odor from an odor generating source. A deodorization tower discharges the organic acid and the condensed water separated. An organic acid supply unit supplies the organic acid to a carrier layer. A food collection box is selectively connected with the steam separator. A sealing part seals the food collection box. A connection sensor unit senses whether the reactor is connected with the steam separator or not. A food dehydrator is provided with a filter and an activated charcoal filter, and deodorized the odor flowing according to a drying oil furnace. An opening/closing valve selectively opens the drying oil furnace. A shielding member prevents the evaporation of the organic acid stored in a waste water storage part. A plasma generator generates plasma. A driver rotates a cleaning member that cleans the sludge remaining in the filter layer. An inner portion filtering element is provided in a side of an ultrasonic generator. A compressor is provided at the inner portion of the reactor for compressing the refrigerant. A condenser condenses the compressed refrigerant. An evaporator evaporates the refrigerant.
