摘　　要：芬顿(Fenton)氧化法被用于处理酿造废水二级出水,通过单因素试验确定了芬顿氧化的最佳条件。结果表明芬顿试剂的H_(2)O_(2):Fe^(2+)为1.5:1。当Fe SO_(4)的投加量为2.96 mmol/L,H_(2)O_(2)的投加量为2.00 mmol/L,PAM的投加量为1.6 mg/L时,COD平均去除率为79.96%。经处理后的出水COD能够达到国家水质排放标准。与现有工艺相比,该药剂能够代替漂粉精,达到保护外界环境,维持生态平衡的要求。Fenton oxidation was used to treat the brewing wastewater secondary effluent,and the best condition was confirmedby the single factor experiment.The results showed that the ratio of H_(2)O_(2)and Fe^(2+)was 1.5:1.Whenthe dosage of Fe SO_(4),H_(2)O_(2),and PAM were 2.96 mmol/L,2.00 mmol/L,1.6 mg/L,the average removal rate of CODwas.After processing,the COD of effluent water quality could meet the national discharge standards.In order to protect the environment and maintain the ecological balance,the Fenton reagent couldtake the place of Ca(Cl O)_(2),Comparing with the existing technology.
