中文摘要：

采用Fenton法预处理干法腈纶聚合废水，考察H2O2投加量、Fe2＋投加量及pH对Fenton反应过程中氧化和絮凝作用去除废水有机物的影响。结果表明，在H2O2投加量为90mmol／L，Fe2＋投加量为30mmol／L，初始pH为3．0的条件下，反应120min后调节pH至6．0进行絮凝，废水中TOC总去除率可达55．6％，Fenton氧化和絮凝作用可实现较好的有机物去除效果。Fenton氧化后将pH调至8．0，有利于絮体的沉降，在实际应用中更加合理。三维荧光光谱（EEM）和荧光区域积分（FRI）发现，Fenton反应能够去除废水中大部分类蛋白易降解有机物，氧化作用对废水中类富里酸有机物的去除作用较小，该类物质主要通过絮凝作用去除。

英文摘要：

Fenton method was used for the pretreatment of polymeric wastewater in dry-spun acrylic fiber production. The effects of H2O2 dosage, Fe2＋ dosage, and pH on organics removal were evaluated during the oxidation and flocculation process. The results showed that the total TOC removal efficiency could reach 55.6%, and both oxidation and flocculation processes could achieve high organics removal, when operated under the conditions of H2O2 dosage 90.0 mmol/L, FeE＋ dosage 30.0 mmol/L, initial pH 3.0, reaction time 120 min and floceulation pH 6.0. The sedimentation of flocs could be advanced in practical application when the flocculation pH was 8.0. Excitation-emission matrix spectroscopy and fluorescence regional integration revealed that most of the protein-like degradable organics were removed during the Fenton process, and the oxidation could hardly remove the fulvic-like organics, which were mainly removed by the flocculation process.
