Abstract
The invention discloses an apparatus and a method for UV oxidation and microbiological decomposition of organic waste air. The invention provides an integrated system consisting of UV oxidation as a pretreatment process and biofiltration and biotrickling filtration, in which the organic pollutant residuals are decomposed with microorganisms.
Claims16
A method for UV oxidation and microbiological decomposition of organic waste air, comprising:
- (a) irradiating the organic waste air to a first UV treatment, wherein the organic pollutants in the organic waste air undergo a first oxidation reaction;
- (b) irradiating the organic waste air to a second UV treatment, wherein the organic pollutants in the organic waste air undergo a second oxidation reaction;
- (c) neutralizing the organic waste air by an acid neutralizing process to neutralize the pH value of the organic waste air after the first and second oxidation reaction;
- and
- (d) polishing the organic pollutant residuals of the organic waste air by passing the organic pollutant residuals through at least one biofilter with microorganisms.
