摘　　要：以RuO_(2)-IrO_(2)-TiO_(2)/Ti电极作为阳极,以ACF电极作为阴极,向阴极不断通入空气,加入定量FeSO4·7H_(2)O,用硫酸溶液调节合适的pH值,电解过程中生成的H_(2)O_(2)与阳极溶解的Fe^(2+)形成Fenton试剂,利用Fenton试剂在电解的过程中产生的大量活性羟基的强氧化作用来氧化降解废水中的有机物。实验表明,当电解电压为20 V、溶液pH=3.5、电解时间为60 min、电解质Na2SO4投加量为8 g/L、曝气强度为20 mL/s时,邻硝基氯苯的去除率可以达到80%以上。RuO_(2)-IrO_(2)-TiO_(2)/Ti electrode was used as anode,ACF electrode as cathode,air was continuously introduced into the cathode,and FeSO_(4)·7H_(2)O was added,the H_(2)O_(2) formed in the process of electrolysis and the Fe^(2+)dissolved in the anode formed Fenton reagent,which was used to oxidize and degrade the organic matter in the wastewater by the strong oxidation of the active hydroxyl OH produced in the process of electrolysis.The experimental results show that when pH=3.5,electrolytic voltage 20 V,electrolytic time 60 min,electrolyte Na_(2)SO_(4) concentration 8 g/L,aeration intensity 20 mL/s,the removal rate of o-nitrochlorobenzene can reach more than 80%.
