| 摘 要： | 研究了单介质阻挡放电-紫外光电离剂(SBD-UV)协同降解苯的效应.研究结果表明,紫外光能与等离子体协同作用,促进苯的降解.外施电压较高时,SBD-UV254nm作用效果增大.在9 kV的电压下,SBD-UV254nm可以使苯的降解率和矿化率提高10%左右,结焦率变化不大;外施电压较低时,SBD-UV185nm使苯的降解率、矿化率提高较明显,同时结焦率也有增加.

| Abstract: | The synergism of SBD - UV on the decomposition of benzene was studied. The results show that the synergism of UV energy and plasma can promote the decomposition of benzene. The decomposition rate of benzene by SBD - UV254nm increased obviously at high voltage. The decomposition rate and mineralization rate of benzene under 9 kV increased by 10% when the SBD- UV254nm Was used, while the polymerization rate did not change greatly. At low voltage, the decomposition rate and mineralization rate of benzene obviously increased when the SBD - UV185nm was used, and the polymerization rate increased as well. |
