  • 摘要: 采用Fenton法处理湿法腈纶聚合废水,考察了H2O2投加量、Fe2+投加量、pH和反应时间等因素对氧化和混凝作用去除废水污染物的影响,并分析了废水可生化性和特征污染物的变化。结果表明,Fenton法可以有效去除废水中有机污染物,在初始pH为3.0,Fe2+投加量为15.0 mmol/L,H2O2投加量为90.0 mmol/L的条件下,反应120 min后废水COD去除率可以达到56.8%,其中氧化和混凝作用对应的去除率分别为43.3%和13.5%;处理后废水的BOD5/COD由0.24升高至0.43;处理后废水中丙烯腈以及其他多数有机污染物能被有效去除。
    Abstract: Fenton process was used for the pretreatment of wet-spun acrylic fiber polymerization wastewater.The effects of initial pH value, H2O2 dosage, Fe2+ dosage and reaction time on organics removal were investigated during the oxidation and coagulation processes.The variations of biodegradability and characteristic organic pollutants were also analyzed.The results showed that the organic pollutants were degraded efficiently and the CODremoval efficiency reached 56.8% under the optimized conditions with initial pH value of 3.0, H2O2 dosage of 90.0 mmol/L, Fe2+ dosage of 15.0 mmol/L and reaction time of 120 min, under which 43.3% COD was removed by oxidation process and 13.5% COD was removed by coagulation process.The BOD5/CODratio increased from 0.24 to 0.43 after 120 min treatment.Most of the organic pollutants such as acrylonitrile were removed efficiently during the Fenton pretreatment.
