Apply the pulse power electrolysis to eliminate aluminum anodic passive films in the process of electrocoagulation . Electrolysis current half life, open circuit potential after polarization, removal efficiency for COD Cr and oil were measured and compared between direct current and pulsed current electrocoagulation. The experimental results show that pulsed current electrocoagulation can eliminate the anodic passive films effectively and improve current efficiency. To the same removal efficiency of COD Cr and oil, pulsed current electrocoagulation can reduce energy consumption about 30% in contrast of direct current electrocoagulation. The optimum parameters of plused current electrocoagulation under the experimental conditions were confirmed as 6.8 A/m 2 for current density, 0.15 Hz for frequency, 0.7 for duty cycle, respectively. 脉冲电絮凝 餐饮废水 污水处理 铝阳极钝化 电解电流半衰期 pulsed current electrocoagulation restaurant wastewater wastewater treatment aluminum anodic passivation electrolysis current half life X799 2003-06-01 2021-04-01 6
