摘要: Abstract Pulsed electrochemical process was explored to remove sulfide in municipal sewage, which successfully achieved higher removal rate of 93.2% compared with 73.2% by direct current (DC) power supply. The sulfur content on the electrode 0.21% pulsed that 1.05% anode DC process, indicating can inhibit anodic passivation resulting from deposition process. Besides, scaling also be effectively controlled during Moreover, optimization investigated for treatment, obtained highest 97.8% at pH 7–8, cell voltage 7 V, duty cycle 60%, pulse frequency 1000 Hz and spacing 2.5–3.0 cm. These results indicate is a promising method efficient sustainable sewage.
