Abstract

Abstract: A fluidized bed-Fenton process using quartz sand(0.5mm) as carrier was setup for iron oxides crystallization on the carrier's surface under the conditions of pH of 3.5,Fe²⁺/H₂O₂(molar ratio) of 2:1,influent of 1/3—1/2 design,and sequentially adding Fenton reagent. Uneven quartz sand surface and uniform fluidized state was beneficial to coating. At the same time the fluidized bed of highly efficient mass transfer further enhanced this process. The main components of iron oxides were FeOOH,Fe₂O₃,FeO and Fe₂(SO₄)₃ according to X-ray diffraction(XRD) analysis. Simultaneously,this system also was used to treat organic silicone wastewater and synthesis pharmaceutical wastewater,COD and TOC removal rates could reach 80% and 85%,respectively,and the efficiency of Fe³⁺removal reached 26% under optimum conditions.

摘要： 以石英砂(0.5mm)为载体,建立流化床-Fenton系统,在pH值为3.5、Fe²⁺/H₂O₂摩尔比为2:1和进水量为试验装置设计进水量的1/3～1/2条件下,连续加入Fenton试剂,使得铁氧化物在载体表面结晶。这是因为凹凸不平的石英砂和均匀的流化状态有利于铁氧化物的覆膜,同时具有高效传质的流化床进一步强化覆膜过程。通过XRD分析可知,铁氧化物的主要成分是FeOOH、Fe₂O₃、FeO和Fe₂(SO₄)₃。同时将此系统用于处理有机硅废水和合成制药废水,在优化操作条件下,COD和TOC的去除率可达80%和85%,总铁(Fe³⁺)的消减量达26%。
