Embodiment 1
[0018] Using the three-dimensional electrode reactor of the present invention to treat EDTA wastewater, the control process conditions are: EDTA wastewater 500mL, pH value 7.7, water inflow rate 200mL / min, current density 40A / m 2 , when the influent COD is 500mg / L, the effluent COD is 46mg / L in 0.5h, and the removal rate reaches over 90%. Respectively 172mg / L and 194mg / L (see attached figure 2 ), reaching the national "Integrated Wastewater Discharge Standard" (GB8798-1996).
Embodiment 2
[0020] The waste water containing EDTA, sodium dodecylbenzenesulfonate and phenol is treated respectively with the three-dimensional electrode reactor of the present invention, the control process conditions are: waste water 500mL, influent pH value 7.7, influent COD concentration is 1000mg / L, influent Water velocity 200mL / min, current density 40A / m 2 , the effluent COD concentration was lower than 100mg / L in 3 hours, and the removal rate was higher than 90% (see attached image 3 ), reaching the first-level standard in the national "Integrated Wastewater Discharge Standard" (GB8798-1996).
