摘要
油基钻屑的处理与资源化利用一直是研究热点。以油基钻屑为基材,由固态烧结法制备多孔载体,通过浸渍-焙烧法制备以CuSnSb为活性组分的金属粒子电极,构建三维电催化氧化体系,用以处理含酚废水。考察了粒子投加量、脉冲频率和占空比对COD_(Cr)去除率的影响。结果表明,在粒子投加量为40 g/L,脉冲频率为2 400 Hz,占空比为0.5条件下反应40 min, COD_(Cr)去除率可达74.8%。
The treatment and resource utilization of oil-based drill cuttings has always been a research hotspot.The porous carrier was prepared by solid-state sintering method with oil-based drill cuttings as the substrate, and the metal particle electrode with CuSnSb as the active component was prepared by the impregnation-calcination method.A three-dimensional electrocatalytic oxidation system was constructed to treat phenol-containing wastewater.Effect of particle dosage, pulse frequency and duty cycle on the COD_(Cr)removal rate of phenol-containing wastewater were investigated.The results showed that the COD_(Cr)removal rate was 74.8% under the conditions of particle dosage of 40 g/L,pulse frequency of 2 400 Hz, and duty cycle of 0.5 for 40 min.
