本人投稿化工进展,初审通过,但是英文摘要不合格,本人英文水平有限,请各位大神帮忙翻译一下,重金酬谢!翻译要求见附件,翻译内容: 摘要:现有废碱液处理技术难以经济有效地回收其中的有机物,为了解决这一问题,开展了萃取-大孔树脂吸附法处理废碱液、高效回收有机物的实验研究,实验结果表明:当废碱液的ρ(COD)为104651mg/L时,以己烷为萃取剂,在pH=3、己烷与废碱液的体积比为0.5、萃取级数为2等条件下,出水ρ(COD)可降至6453mg/L以下,COD去除率达到93.8%以上,萃取剂己烷可以通过精馏再生循环利用;采用HYA-106大孔吸附树脂对二级萃取出水进行吸附处理,HYA-106大孔吸附树脂较佳的吸附流速为1BV/h、温度为20~40℃、pH为3~4,此时出水ρ(COD)平均在155~183mg/L之间,COD去除率在97.1%~97.4%之间,单位体积树脂的废水处理量为34BV以上,树脂吸附量在213~215mgCOD/ml树脂之间,吸附-解吸效果稳定;萃取-吸附工艺的COD总去除率达到99.8%以上,最大程度地实现了废碱液中的有机物回收。 在线等,谢谢! |

| The experimental study on waste alkali treatment has been carried out by extraction-macroporous resin adsorption method to recover the organic contained in due to the difficulty of existing technology to fulfill this purpose. The results show that the ρ(COD) of the waste alkali decreased from 104651mg/L to 6453mg/L when using hexane as the extraction agent, in pH = 3,volume ratio of hexane to waste alkali liquor is 0.5 and the extraction stages is 2, extraction agent can be recycled by distillation. Then HYA-106 macroporous resin has been use to adsorption the secondary extraction effluent with the preferred condition of adsorption flow rate is 1BV/h, temperature range is 20 ~ 40 ℃, pH 3-4, the result can be derived that the ρ (COD) on average decreased to 155 ~ 183mg / L, COD removal efficiency is between 97.1% ~ 97.4%, wastewater treatment capacity of per unit volume of the resin is more than 34BV and the amount of resin adsorption is between 213 ~ 215mgCOD / ml resin, the adsorption-desorption is stability. Total COD removal efficiency of Extraction - Adsorption Process reached 99.8%, which realised the purpose to maximize recovery of the organic in waste alkali. |
