通过测定人工湿地植物叶片中叶绿素含量、MDA含量及SOD酶活性.研究不同通电强度下人工湿地植物生理特性变化,分析电场对植物生理特性的影响机理,为利用电场强化人工湿地去除污染物提供依据.研究结果表明,与对照植物相比,1和3 V低强度电压对植物正常生理指标变化无明显影响,且生长趋势优于对照组;随着电压强度的升高,植物叶片中叶绿素含量、MDA含量以及SOD酶活性受到较大影响,表明植物体受到较强的氧化胁迫,生长受到危害.合适的电场能够强化人工湿地的污水处理效果.

By measuring wetland plants chlorophyll content,malondialdehyde (MDA) content and superoxide dismutase (SOD) enzyme activity,the changes of wetland plant physiological characteristics under different power strength were studied,and the mechanism of electric field on plant physiological characteristics was analyzed to provide a theoretical basis for the pollutant removal ability strengthening of artificial wetland under electric field.The results showed that compared with the control plants,low-intensity-voltage (1 V and 3 V) had no significant effect on the normal physiological and biochemical indexes of the plants,and the growth trend was better than the control group;with the voltage increasing,plant chlorophyll content,MDA content and SOD activity were greatly affected,indicating that plants were under strong oxidative stress,and the growth was damaged.Therefore,a suitable electric field could enhance the sewage treatment effect of constructed wetland.
