Decomposition of dioxin-like components in a DBD reactor combined with Hg/Ar electrodeless ultraviolet

A new combined reactor with Hg/Ar electrodeless ultraviolet(EDUV)activated by DBD for 3,4-dichlorodiphenyl ether abatement is presented.The effect of specific input energy and feeding gas component on 3,4-dichlorodiphenyl ether removal efficiency has been explored.Compared with a single DBD system,this new combined process performed a significant promotion on 3,4-dichlorodiphenyl ether abatement.Experiment results verified that active oxygen clearly contributed to the synergistic activity of DBD-EDUV system.Results of emission spectra showed that UV radiation of 253.7 nm could be detected in the DBD-EDUV system.Further,the products of DBD-EDUV process were analyzed via gas chromatographymass spectrometer(GC-MS)to reveal involved decomposition mechanism.

高级氧化法对城市污水深度处理过程中的影响因素

本文考察了UV／O3法对城市污水深度处理过程中的主要影响因素。结果表明有机污泥对COD去除率基本没有影响，但无机悬浮物SiO2对COD去除率影响较大，投加70mg／L的SiO2后COD氧化速率和去除率有较明显下降。UV／O3法处理城市污水生化处理水时，在pH=6～9范围内，COD去除率随pH值的升高而降低，说明较低pH值（pH=5）有利于COD的去除。随溶液碱度的增加，COD的去除率下降，碱度越高对COD去除的影响也越明显。SS、pH和碱度对UV260去除的影响均小于对COD去除的影响。

Effect of Water Vapor on Toluene Removal in Catalysis-DBD Plasma Reactors

The experiment was carried out in a cylindrical dielectric barrier discharge(DBD)reactor assisted with a catalyst to decompose toluene under different humidity.In order to explore the synergistic effect on removing toluene in the catalysis-DBD reactor,this paper investigated the decomposition efficiency and the energy consumption in the catalysis-DBD and the non-catalyst DBD reactors under different humidity.The results showed that the catalysis-DBD reactor had a better performance than the non-catalysis one at the humidity ratio of 0.4%,and the removal efficiency of toluene could reach 88.6% in the catalysis-DBD reactor,while it was only 59.9% in the non-catalytic reactor.However,there was no significant difference in the removal efficiency of toluene between the two reactors when the humidities were 1.2% and 2.4%.Additionally,the degradation products were also analyzed in order to gain a better understanding of the mechanism of decomposing toluene in a catalysis-DBD reactor.
