Acrylic Fiber Polymerization Unit Wastewater Pretreated by the Integrated Fenton Reactor
摘要/Abstract
采用自主设计一体化Fenton反应器,进行了处理腈纶聚合单元生产废水的效能及影响因素研究.结果表明,一体化Fenton反应器能实现对CODcr、丙烯腈及CN-的有效去除,同时提高了废水可生化性.获得的最佳工艺参数:H2O2和Fe2+投加量分别为0.2 mol/L和28.8 mmol/L,pH值3.0,停留时间150 min.出水回流可改善处理效果,在最佳工艺条件下,出水回流比为100%时,废水CODcr质量浓度可从1 247.9 mg/L降至124.1 mg/L,去除率为90%,废水中难生物降解的低聚物被彻底去除,特征污染物丙烯腈的质量浓度从75.5 mg/L降为0,CN-的质量浓度从5.40 mg/L降至0.12 mg/L,去除率为97.8%,出水可生化性指标从0.08提高到0.36.
The influences and efficiency of acrylic fiber polymerization wastew ater treated by the integrated Fenton reactor are studied.The test results show CODcracrylonit rile and CN-,can be removed ef fectively by the integrated Fenton reactor,the biodegradability is improved obviously.The optimum condi tion of the integ rated Fenton reactor is as follows:the concentration of hydrogen peroxide and ferrous ion are respectively 0.2mol/L and 28.8mmol/L,pH =3.0 and the reaction time is 150 min.Treatment ef fect can be improved by adjusting return f low ,while the reflux ratio is 100%in the condition of optimum condition.The CODcr of the acrylic fiberw astew ater isdegraded from 1247.9mg/L to 124.1mg/L,and the removal rate reaches 90%,the dif ficul tlybiodegraded oligomer is removed completely ,the main pollutant acry lonit rile degrade from 75.5mg/L to 0,thedosage of CN-is deg raded from 5.40mg/L to 0.12 mg/L ,the removal ef ficiency is 97.8%,the B/C of effluentimproved f rom 0.08 to 0.36.
