摘要： To investigate the effects of solid packing on the physical and chemical processes and the removal of cyanobacterium (Microcystis aeruginosa), the comparisons of properties of the plasma reactors with and without glass pellets and the algal removal efficiency in the plasma reactor were discussed. Experimental results show that more than 27% of the peak value of discharge current and 14.14% of the removal efficiency were increased by the addition of glass pellets. H2O2 concentration in the plasma reactors with glass pellets was at least eight times greater than that without them at an air flow rate of 0.75 m(3)/h after 40 min of treatment. The algal removal efficiency and H2O2 concentration in the system with glass pellets having a diameter of 3-4 mm were higher than that of 7-8 mm. These results implicated that M. aeruginosa growth was inhibited by plasma, demonstrating the considerable potential of such an alternative process for water purification.
