摘要

For the improvement of decomposition efficiency in the treatment of the dilute Trichloroethylene(TCE), Dielectric Barrier Discharge (DBD) reactor combined with Manganese Dioxide (MnO_2 at the downstream of the reactor was experimented in the background gas of N_2 and O_2 (4:1) at the atmospheric pressure. Decomposition efficiency without catalysts in the Direct Process was about 83 percent at the flow rate of 2 Lmin~(-1) of 250ppm, however, lots of byproducts as well as ozone were detected in the measurement of GCMS and FUR. By using catalysts of MnO_2, decomposition efficiency was improved more than 99 percent as well as decrease of byproducts. In addition, Indirect Process by using DBD reactor as ozone supplier was showed high decomposition efficiency of about 80 percent as well. Oxygen radicals on the surface of catalyst generated from ozone decomposition are thought as main species for the additional decomposition of TCE and toxic-byproducts. These reactions were confirmed indirectly by the variation of COx, however, carbon balance (CO+CO_2) was low about 50 percent in all of experiments, even if it was improved about twice by using the catalytic process. It will be investigated by changing experimental parameters and this kind of process will be anticipated to the application in lots of studies in the near future.
