This paper is aimed at discussing an applied research on how to remove volatile organic compounds (VOCs) by impulsive corona discharging technology. Known as a promising new technology, the control of volatile organic compounds (VOCs) has been receiving more and more attention. Theoretically, the whole technology is built on a set of equipment for experiments, on which the experiment is conducted to study the effect of the benzene destruction. The total research emphases the effect of the removing efficiency of benzene dependent on the concentration, the time of staying in the reactor, the injected energy and the capability of the impulsive high voltage generator. The results of the experiment show that the removing efficiency of benzene decreases with the rising of inlet concentration of benzene, the prolonging of the time of staying in the reactor as well as the increase of the energy input and the spiking voltage. The defining factors of benzene-removing efficiency are the capability of the pulsed high voltage generator and the structure of the reactor. At an input voltage of 50 V, the average removing efficiency will be about 50% on average. When the other conditions of the system changed, The removing efficiencies may vary in the range of 38.3%~63.2% with the change of input voltage. For example, the removal efficiency will be equal to 61.4% with the input voltage being 50 V, the gas flow rate-1 620 mL/min.and the inlet concentration of benzene-76.8 mg/m~3. The presence of oxygen in the pulsed corona discharge process can contribute to the removing efficiency, though it isn't the decisive factor for the removal. The byproducts that are produced, analyzed and confirmed include: phenol, nitrobenzene, 1,2-benzenediol, 1,3-isobenzofurandione, 1,4-dinitrobenzene, 1,4-benzenediol, 3-nitrophenol, 4-nitrophenlo. From the above results it can be found that the chief factors that contribute to the removing efficiency may include improving the capability of the pulsed high voltage generator and the reactor structure, and ensuring high degree matching between them.

The removal of flowing SO 2 was studied in the absence of NH 3 by cold plasma generated by high frequency dielectric barrier discharge. The results showed that the decomposition rate was over 70% at the experimental conditions of 12 kV input voltage and 55% relative humidity with the SO 2 concentration of 5400 mg/m 3 and the gas flux of 0 36 m 3/h. The added H 2O(g) played an important role in the SO 2 removal, and in addition, the increasing O 2 and input voltage exerted a little influence on the decomposition...

The characteristic of the o-chlorophenol degradation by pulsed high voltage discharge was investigated in present work.The concentration of o-chlorophenol declined faster by a shortening distance, increasing peak voltage or frequency.A degradation efficiency of 98.7% for o-CP is achieved after degradation for 30 min under the conditions of 2 cm of the electrode distance, 30 kV of the peak voltage and 150 Hz of the frequency.It was found that the discharge form was determined not only by the peak voltage and the electrode distance, but also by the salt content in the solution. The increase in salinity could cause a transition from spark discharge to stream discharge and then to corona discharge. The concentration of o-chlorophenol declined faster in the spark and stream discharge than in the corona discharge. The degradation of o-chlorophenol is attacked by hydroxyl radical to form 2-chloro- hydroguinone.The later is oxidized to 2-chloro-benzoquinone.Therefore, the ring is opened to form simple organic acids such as metacetonic acid, oxalic acid, acetic acid and formic acid.
