磁场协同Ca_2O_2/Fe^(2+)处理活性红染料废水的实验研究

Study on the Treatment of Active Red Dye Simulating Wastewater with Catalytically Oxidatize System of Magnetic-assistant Ca_2O_2/Fe^(2+)

利用磁场协同Ca2O2/Fe2+催化氧化体系处理活性红染料废水,研究不同磁化时间、磁场强度和催化氧化各种影响因素下对活性红染料模拟废水的去除率。结果表明:在pH值为3,C(FeSO4·7H2O)=50mg,C(Ca2O2)=1.45g条件下,反应20min,去除率达62.5%。外加磁场磁场强度为427.8mT的作用下,磁化反应20min,CODCr的去除率提高了8.3%。

The treatment of reactive red dye simulative wastewater by magnetic-assistant Ca2O2/Fe^2＋ catalytically oxidize system has been studied under different magnetic-assistant reaction time, intensity of magnetic field and the optimum dosage of catalytically oxidize system. The results showed that the removal rate of CODCr reached 62.5% when pH was 3, FeSO4· 7H2O was 50 rag, Ca2O2 was 1.45 g and reaction time was 20 min. Comparatively, when magnetic intensity was 427.8mT and magnetic reaction time was 20 min, the removal rate of CODCr was 8.3% better than without magnetic field.
