Abstract

Abstract:

Aluminum is selected as the doping component. With the mass ratio of iron, aluminum and carbon of 3:1:1, the porous spherical structured metal alloy filler is sintered by the high-temperature sintering process and then characterized by SEM and EDX. The filler exhibits stable structure, wearing capacity, compressive resistance, large comparative area and porosity. Finally, it is applied in the treatment of refinery wastewater, which shows excellent effect.

Key words: micro-electrolysis, filler, wastewater treatment

摘要：

以铝作为掺杂成分，在铁、铝和炭最佳质量比为3：1：1的条件下，用高温烧结工艺将其烧制成多孔性球形规整化金属合金架构填料，并进行SEM和EDX表征。该填料具有稳定的结构和耐磨抗压能力，同时有较大的比表面积和孔隙率，用于处理炼油废水时达到良好效果。
