| 中文摘要: |
| 提出了糖精合成酸性含铜废水资源回收与预处理的工艺路线,并对加温、曝气和金属置换与废水COD、Cu2+浓度、酸度、色度变化之间的关系进行了深入的研究,提出最佳曝气温度为80℃,时间为1 h,此时铜置换率达80%,COD去除率50%,酸度去除13%. |
| 英文摘要: |
| This article focused on the pretreatment of the waste water engendered by the production process of glucide.The waste water includes high concentration of Cu2+ and acidity.This study researched the effects of three main factors: temperature,oxygenation and metalline replacement reaction,and also discussed the relationship among COD,Cu2+,acidity and chroma.In the end,we put forward the appropriate condition of pretreatment,including the best aerate temperature at 80℃ for 1h and so on.The ratio of copper displacement reached 80%,COD was wiped off by 50%,acidity was removed by 13%. |
