Fenton-超声联合处理金刚烷胺制药废水

近年来,流感常用药盐酸金刚烷胺的产量不断增大,然而,其生产过程中产生的废水由于得不到有效处理,引起较大污染。以盐酸金刚烷胺生产过程中产生的胺化废水和溴化废水为原水,利用Fenton-超声联合工艺进行处理,主要研究反应时间、初始pH、H2O2投加量和H2O2/Fe2+的投加比和声能密度等操作条件对于金刚烷胺制药废水处理效果的影响。实验结果表明,优化处理条件下,Fenton-超声联合工艺对金刚烷胺制药废水中TOC去除效果最高达到65.6%。超声和Fenton的联合产生了良好的协同效果,Fenton-超声联合工艺对金刚烷胺制药废水的处理效果比单独超声和单独Fenton处理效果之和高18%,大大提高了废水中有机物的去除效果。

Treatment of wastewater from amantadine production by Fenton-ultrasound process

As one kind of frequently-used flu medicines, amantadine has been increasingly produced these years, however, the wastewater from amantadine production can't be effectively treated, leading to serious pollution. This study aims at the treatment of wastewater from amantadine production with Fenton-ultrasound combined process. Effects of reaction time, initial pH, H₂O₂dosage, H₂O₂/Fe²⁺ molar ratio and ultrasound power density on the wastewater treatment effectiveness were investigated. Results showed that the TOC removal can reach 65.6% under the optimum reaction conditions. Ultrasound and Fenton treatment showed a good synergy effect that the TOC removal of the combined treatment was 18% higher than the sum of single ultrasound and single Fenton treatment, which greatly promoted the organic removal from the wastewater from amantadine production.
