摘要
腈纶生产中会产生大量有机废水,是一种难降解有毒工业废水。其水质复杂,可生化性差,且存在对微生物起抑制作用的成分。腈纶废水的达标排放一直是水处理里领域的一大难题。而Fenton试剂中Fe2+作为同质催化剂有利于H2O2分解产生OH·,该自由基比其他氧化剂有更强的氧化电极电位(2.80 V),具有很强的氧化性能。文章主要是对Fenton法机理及其相关组合工艺处理腈纶废水的研究现状进行综述,提出难降解有机废水(腈纶废水)处理工艺的研究方向。
Acrylic production will generate a lot of organic wastewater, which is a kind of organic chemical industrial wastewater. The water quality is complexity and poor biodegradability. The treatment of acrylic fiber wastewater has been a major problem in the field of water treatment.Fe2＋ as homogeneous catalyst of Fenton reagent is conducive to H2O2 producing OH-, which has stronger oxide electrode potential （2.80 V） and stronger oxidation performance than other oxidant. The article is mainly to review the study of the oxidation mechanism of Fenton reagent and its related technology research status quo of acrylic wastewater treatment. To put forward the research direction of the refractory organic wastewater （acrylic） wastewater treatment technology.
