摘 要:采用Fenton高级氧化和铁碳微电解技术处理含硝基苯的模拟染料废水,通过重铬酸钾法测定化学需氧量(CODCr),确定最佳工艺参数。实验结果表明,在室温条件下,模拟废水CODCr为1825 mg/L,Fenton高级氧化处理废水的最佳条件为FeSO4和H2O2加入量分别为180 mg/L和4.8 mL/L,反应时间60 min,CODCr去除率可达79.07%;铁碳微电解处理废水的最佳条件为铁屑大小是40目,铁碳加入量为20 g/L,铁碳质量(g)比为1.5∶1,处理60 min,CODCr去除率可达50.50%;Fenton高级氧化-铁碳微电解联合处理时,CODCr去除率高达97.80%。The methods of Fenton advanced oxidation and ferric-carbon micro electrolysis were studied about simulated dye wastewater containing Nitrobenzene.CODCr was detected by potassium dichromate method,and optimum conditions were determined.Experimental results showed that,under common temperature,when the CODCrof simulated wastewater was 1825 mg/L,the optimum conditions of Fenton advanced oxidation were that FeSO4=180 mg/L,H2O2=4.8 mL/L,the reaction time was 60 min,at that time the CODCr removal rate reached 79.07 %;the optimum conditions of ferric-carbon micro electrolysis were that the size of Fe was 40,Fe-C powder =20 g/L,the quality of Fe/C=1.5:1,the reaction time was 60min,at that time the CODCr removal rate reached 50.50 %;CODCr removal rate could reached 97.80 % when the methods of Fenton advanced oxidation and ferric-carbon micro electrolysis combined.
