The Study on the influence factors for the treatment of oil wastewater by Ti electrode- Low-voltage pulse electrolysis

摘要

The test of influence factors on treatment of oily wastewater by Ti electrode- Low-voltage pulse electrolysis was performed. The results showed that the removal rate for 95.0mg / L oily waste water was between 65 and 80%. The electrolytic effect was growing with the electrolysis time prolonging and electrolysis- voltage increasing, and the growth became slow after a certain value because of the concentration proliferation; the appropriate pulse frequency duty cycle can not only eliminate effects of passive, but also enhance the effect of electrolysis. The pH value impacted on electrolysis greatly and acidic condition was better than alkali. Appropriating to adjust the diameter of the electrode and the electrode spacing was benefit to enhance the electrolytic effects.
