Upgrading and optimizing method and apparatus to treat RTO (regenerative thermal oxidizer) waste gas of pharmaceutical and chemical enterprises

The invention provides an upgrading and optimizing apparatus to treat RTO (regenerative thermal oxidizer) waste gas of pharmaceutical and chemical enterprises. The apparatus herein comprises a fan, aplant extraction micro-spray absorbing column, and a bio-deodorizing tank which are communicated in sequence. The apparatus herein has the advantages that the problem of allowing waste gas of pharmaceutical and chemical enterprises to be emitted under the new emission standard is solved, and especially, the odor concentration index of pharmaceutical and medical waste gas emission is originally 2000 (dimensionless) in Emission Standard for Odorous Pollutants and is increased to 500 (dimensionless) in the new local standard, Emission Standard for Atmospheric Pollutants from Chemic Synthesis Pharmacy Industries DB33/2015-2016; the upgrading and optimizing process for bio-deodorizing has better removal thoroughness and is, up to now, capable of stably decreasing the odor concentration for pharmaceutical and chemical w
