摘　　要：研究了复合电化学法处理含盐、酚废水的可行性及处理效果。实验结果表明 ,在 110～ 160℃、p H3～ 3 .5、处理电压 5V、电流密度 6～ 9m A/cm2、H2 O2 /苯酚 (质量比 ) >0 .0 6时 ,2 0 0 mg/L的苯酚溶液经处理后 ,酚去除率大于 98% ,CODCr去除率大于70 %。该法电能消耗低 ,是一种适合于含盐有机废水处理的新方法。Feasibility and effect of complex electrochemical method are studied dealing with organic effluents containing NaCl of high concentration. The results show that if we keep the temperature 110~160 ℃, the electric current density at 6~9 mA/cm\+2, voltage=5.0 V, the pH at 3~3.5, the H\-2O\-2/phenol>0.06, the phenolic \{wastewater\} of 200 mg/L as initial concentration will get the removal at above 98%, accompanied by the removal rate of being up to over 70%. The electric energy consumed is low. It is a new method for treatment of organic effluents containing salt in high concentration.\;
