快速降解苯酚废水的优化纤维制备及其降解效果

Optimized Fiber Preparation and Its Rapid Degradation of Phenol Wastewater

以接枝共聚纤维为原料负载Fe^(3+)制成优化纤维,结合高级氧化技术以类芬顿反应降解酚类废水.从pH、反应时间、投加量、苯酚溶液初始浓度和用于负载的硝酸铁溶液质量分数5个方面研究优化纤维对苯酚废水处理效果的影响.结果表明:降解100mL浓度为1 000mg/L苯酚废水,在pH 6.0、纤维投加量0.8g、降解时间35min、硝酸铁溶液质量分数20%时,降解效果最佳.

Grafting copolymer fiber is used as raw material for producing optimized fiber with iron ion loading,which is combined with advanced oxidation technology to degrade phenol wastewater by Fenton like reaction.From the five aspects of pH,reaction time,dosage,initial concentration of phenol solution and the mass fraction of ferric nitrate solution used for loading,the effect of optimizing fiber on phenol wastewater treatment is studied.The results show that for the degradation of 100 mL concentration of 1 000mg/L phenol wastewater,pH of 6,fiber dosage of 0.8grams,30 minutes of degradation,mass fraction of iron nitrate solution load of 20%,result in the best treatment effect.
