ABSTRACT
In this paper the design and manufacture by two-dimensional electrode to the reactor, the orchid carb on wastewater pla nt for electrochemical oxidati on degradati on, mai nly is the Chemical oxyge n dema nd (COD) removal and ammo nia nitrogen (NH3-N) wastewater. This experiment is mainly the electricity using electrochemical oxidati on fenton react ion method, detailed an alysis of electrolytic current, electrolytic time, wastewater primitive pH value, plate spacing and hydrogen peroxide dosing quantity factors in two-dimensional electrode system in the effects of polluti on degradati on.
To study the two-dimension electrode electricity catalytic degradation the in flue nee factors of Abram carb on wastewater .By the experime ntal data show that economic and effective treatment condition: electrolytic current as 5A, electrolytic time 210min, plate spacing for cm, electrolyte (Na2SO4)concentration of 1Og/L, double oxygen dosing quantity 1mL / 100mL canister wastewater, do not add acid-base adjust pH value, the no rmal reacti on Chemical oxyge n dema nd (COD) removal efficiency of maximum close to 80%, Ammonium-Nitrogen (NH3-N) removal rate more tha n 80%.
Keywords： Two-dimensional electrode electricity; Fenton； Chemical oxygen
dema nd (COD); Ammo nium-Nitroge n (NH 3-N)
