Treatment of two-dimensional and three-dimensional electrode method was researched and compared respectively using aluminum electrodes. The influences of voltage, electrolysis time, pH and electrode distance on the result were also discussed. It was found that the degradation rate of wastewater with three-dimensional electrode method was much better than two-dimensional method. For the treatment of vehicle-washing wastewater, the best of voltage was 20V, the electrolysis time was 30 min, and the electrode distance was 2cm.

Electrode Method

Three-dimensional electrode method is especially suitable for the treatment of low concentration wastewater containing Cu2+. Study the changes on the Cu2+ removal rate, under the condition of different electrode filling material (such as steel ball, activated carbon, activated carbon and resin). The results show steel ball as filling-material is best. Steel ball has higher removal efficiency of Cu2+, up to more than 80%. Steel ball as filling-material the effect of electrode distance on Cu2+ removal is smallest. Compared with steel ball as filling-material, the response time of activated charcoal is no obvious disadvantage.

TiO2-coated granular activated carbon was employed for the removal of toxic microcystin-LR from water. High surface area of the activated carbon provided sites for the adsorption of microcystin-LR, and the adsorbed microcystin-LR migrated continuously onto the surface of TiO2 particles which located mainly at the exterior surface in the vicinity of the entrances of the macropores of the activated carbon. The migrated microcystin-LR was finally degraded into nontoxic products and CO2 very quickly. These combined roles of the activated carbon and TiO2 showed a synergistic effect on the efficient degradation of toxic microcystin-LR. A continuous flow fluidized bed reactor with the TiO2-coated activated carbon could successfully be employed for the efficient photocatalytic of microcystin-LR.

The synergy between electrochemical oxidation and adsorption on particle electrodes was investigated in three-dimensional (3D) systems for p-nitrosodimethylaniline (RNO) decolorization and pesticide removal. A comparison was made between granular activated carbon (GAC) and a novel synthesized nitrogen-doped graphene-based particle electrode (NCPE). Experiments on RNO decolorization show that the synergy parameter of the 3D-NCPE system was improved 3000 times compared to the studied 3D-GAC system. This was due to the specific nanostructure and composition of the NCPE material. Nitrogen-doped graphene triggered an oxygen reduction reaction, producing hydrogen peroxide that simultaneously catalyzed on iron sites of the NCPEs to hydroxyl radicals following the electro-Fenton (EF) process. Data showed that in the experimental setup used for the study, the applied cell voltage required for the optimal value of the synergy parameter could be lowered to 5V in the 3D-NCPEs process, which is significantly better than the 15–20 V needed for synergy to be found in the 3D-GAC process. Compared to previous studies with 3D-GAC, the removal of pesticides 2,6 dichlorobenzamide (BAM), 2-methyl-4-chlorophenoxyaceticacid (MCPA), and methylchlorophenoxypropionic acid (MCPP) was also enhanced in the 3D-NCPE system.
