Abstract

Oily wastewater is proven to be common both in industry and home life. A particular contaminant of concern is petroleum hydrocarbon present in various types of wastewater comingfrom shipyards, onshore and offshore industries, and engine rooms of ships. As the standards for oily wastewater treatment become more and more strict, and emulsified oil wastewater is characterized by difficult degradation and high toxicity, we adopt the electrocoagulation technology with Al₈₆Ni₁₀Y₄ amorphous alloy as anode and graphite as cathode to treat it to surpass the limitations of conventional methods. The degradation effect on the oily wastewater was characterized by chemical demand oxygen (COD), while the ribbons before and after using were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM) The results show that when the pH value is 3 and the current density is 6.5mA/cm², the COD removal rate can reach to 75.68% within 100 minutes. Large areas of white corrosion products appear on the surface of the Al-based amorphous alloy after reaction. These protrusions are mainly formed by anodic oxidation corrosion of Al-based amorphous alloy. So, the electrocoagulation technology with amorphous alloy as anode and graphite as cathode is suitable for being utilized to treat the emulsified oil wastewater. And it will have a good practical application prospect.
