| Popis: | Under the various current densities, flow rates and the chlorine ion concentrations, the water disinfection in secondary sedimentation tank at boron-doped diamond film electrode was studied. The results showed that the disinfection rate increases with the larger current density and smaller flow rate; it is worthy of note that the chlorine ion concentration has remarkable effects on the wastewater disinfection. After the same cycle numbers, the larger chlorine ion concentration would induce more oxidants in the solution, and then certainly lead to the better disinfection effect. To obtain the higher disinfection rate under a certain chlorine ion concentration, long contact time between the wastewater and the electrode is necessary. |
