摘　　要：分别采用活性炭吸附法、絮凝剂吸附法和氧化法处理钯碳催化剂工业废水,重点考察了试剂加入量及处理时间对废水化学需氧量(COD)的影响,其中氯酸钠氧化法具有最佳处理效果。正交试验表明,氯酸钠处理催化剂废水COD的影响因素中,氯酸钠加入量影响最为显著,优选的条件下,在50 mL废水中加入氯酸钠2.5 g/L,在40℃以200 r/min搅拌处理1 h,可以使废水COD去除率达到87.6%,达到排放标准。Industrial wastewater derived from the preparation of Pd/C catalyst was treated by activated carbon adsorption,flocculant adsorption and oxidation method,respectively.The effects of reagent dosage and treatment time on the chemical oxygen demand(COD)of wastewater were investigated,and sodium chlorate oxidation method had the best treatment effect.According to the orthogonal experimental results,the amount of sodium chlorate was the most significant factor affecting the COD treatment of catalyst wastewater by sodium chlorate.The optimum conditions of orthogonal experiment for 50 mL wastewater were sodium chlorate addition amount of 2.5 g/L,reaction time of 1h,reaction temperature of 40℃and stirring speed of 200 r/min.The COD removal rate of wastewater could reach 87.6%,which meet the discharge standard.
