摘要

To explore the effect of meteorological conditions on pollutants removal and enhancing removalefficiency approaches in weak solar irradiation intensity during photovoltaic energy direct application,electrokinetic remediation of soil containing Cr(VI) was investigated as an example. The results showthat meteorological conditions have a significant effect on pollutants removal, and Cr(VI) removalefficiency for a sunny day is the highest. Cr(VI) concentration and total Cr concentration in thedifferent layer suggest that chromium in soil is electromigrated and accumulated near the anodic2+ region. Total Fe concentration implies that the anodic product Fe is migrated into the cathode.Energy conversion efficiency for a sunny day is the highest and is 10.4%. However, energy utilization3 efficiency for an overcast day is the highest, and Em and Ev are 24.1kWh/kg and 38.3kWh/m ,2 respectively. In weak solar irradiation intensity of 373.5W/m , the parallel connection of photovoltaicpanels is a feasible approach to enhance pollutants removal, and in 30min Cr(VI) removal efficiencyfor four panels can rise to 79.8% from 64.3% for only one panel. The extending reactive time is also afeasible way, and removal efficiency for one panel can increase from 64.3% to 80.7% as timeprolonging from 30 min to 60 min.
