【摘要】 采用混凝沉淀及高级氧化两步工艺对嘧啶废水进行了处理研究。结果表明,在反应温度20℃,pH为3.5,Fe2+的投加量为64mmol·L-1时,Fenton试剂对的嘧啶转化率达74.89%,COD去除率达42.16%;而混凝工艺及H2O2氧化工艺的最高嘧啶去除率分别仅为21.59%和20.20%。通过处理前后的UV/Vis吸收光谱图比较,进一步表明Fenton试剂对嘧啶废水有理想的处理效果。更多还原

【Abstract】 Treatment of pyrimidine Wastewater by coagulation/sedimentation and advanced oxidation technology was preliminarily investigated. The result showed that the conversion efficiency of pyrimidine achieved up to 74.89% and COD removal was 42.16% at reaction temperature 20℃,pH 3.5, Fe2+ concentration of 64mmol·L-1.While pyrimidine removal efficiency of coagulation/sedimentation and H2O2 oxidation technology was only about 21.59% and 20.20% separately. Comparison of UV/Vis absorption spectrum before and after treatment showed that decomposition effect of Fenton reagent on pyrimidine were satisfactory.更多还原
