Embodiment 1
[0022] A method for optimizing the long-term operation performance of a VOC gas biofiltration device using ozone, VOC selects chlorobenzene; after the biofiltration device starts and runs stably, ozone gas is introduced into the chlorobenzene gas before entering the biofiltration device to form a mixed gas, The mixed gas is passed into the biological filter device, and the concentration of chlorobenzene in the mixed gas is 500mg / m 3 , the concentration of ozone is 40mg / m 3 , The empty tower residence time of the biological filter device is 90 seconds.
Embodiment 2
[0024] A method for optimizing the long-term operation performance of a VOC gas biofiltration device using ozone, VOC selects chlorobenzene; after the biofiltration device starts and runs stably, ozone gas is introduced into the chlorobenzene gas before entering the biofiltration device to form a mixed gas, The mixed gas is passed into the biological filter device, and the concentration of chlorobenzene in the mixed gas is 850mg / m 3 , the concentration of ozone is 60mg / m 3 , The empty tower residence time of the biological filter device is 90 seconds.
Embodiment 3
[0026] A method for using ozone to optimize the long-term operation performance of a VOC gas biological filter device. VOC uses toluene; The mixed gas is passed into the biological filter device, and the concentration of toluene in the mixed gas is 1800mg / m 3 , the concentration of ozone is 90mg / m 3 , The empty tower residence time of the biological filter device is 60 seconds.
