EURYTHERMO-MICROBIAL AGENT AND BIOLOGICAL TREATMENT METHODS USING THIS FOR THE SIMULTANEOUS TREATMENT OF MODERATE AND HIGH TEMPERATURE WASTE GASES

摘要

The present invention provides a method for easily obtaining a decomposed microorganism group for removing odor / VOC and a decomposing microorganism group operable at a wide temperature range, and a microbial agent including the decomposed microorganism group, and a odor having a large fluctuation in daily discharge temperature. A new biological treatment method applicable to a / VOC discharge facility.;Photothermal malodorous / VOC decomposed microorganism group to be provided by the present invention mixes and cultivates at least two malodorous / VOC decomposed microorganisms having different operating temperatures, but provides a plurality of temperature steps between the minimum and maximum set temperatures. It can be obtained by incubating for a predetermined time at the temperature step.;In addition, the photothermal malodor / VOC digested microorganisms obtained according to the method can be processed into microbial preparations in liquid, solid or powder form, depending on the requirements of the biological treatment system.;In addition, the biological treatment method of malodor / VOC according to the present invention, the inoculation step of inoculating a photothermal malodor / VOC decomposition microorganism group in a biological removal device that malodor / VOC is decomposed by a biological treatment method; After the completion of the inoculation step, the odor intensity 1000 ~ 3000 OU / ㎥ range of odor / VOC is supplied to the biological removal device for a predetermined period of time so that the photo-temperature odor / VOC decomposition microorganisms are stabilized while decomposing the odor / VOC step; After completion of the transient step, the odor / VOC is decomposed into a harmless / odorless substance by supplying the odor / VOC at an arbitrary concentration and an arbitrary temperature to the biological removal device by decomposing the photothermal odor / VOC decomposition microorganism group. Normal operation step to be made.
