Abstract: The invention discloses a method for processing alkene-containing exhaust gas. It is a combination of ozonic and biological processes which mainly deal with exhaust gas mixtures having alkene-containing (CnullC double bond) organic exhaust gas (such as alkene, acrylic acid) and other volatile organic compounds (such as ketone, alcohol, BTEX, and others). Since exhaust gas containing CnullC double bond is difficult to dispose of, the method for processing exhaust gas presented in the invention utilizes ozone to completely decompose or transform the organic contaminants with CnullC double bonds into intermediate products. The organic contaminant can then be treated in the biological process and converted into non-toxic substances. This method does not require large-sized biological process equipment, and the residual ozone is oxidized and degraded in the bio-filter.

Abstract: The present invention provides a process and apparatus for treating contaminated gas. A contaminated gas containing volatile organic compounds is continuously introduced into a reactor to allow the gas to contact a metal oxide catalyst and an oxidant for a period of time. The concentration of the volatile organic compounds can be thus reduced. The treated gas is then continuously emitted from the reactor. The concentration of the organic compounds of the emitted gas and/or the concentration of the oxidant are continuously monitored, and the oxidant feeding amount is controlled according to the monitored concentration. By means of the process of the present invention, volatile organic compound-containing waste gas with high humidity can be effectively treated, and the utility rate of the oxidant can be increased.
