摘要
本研究旨在通过向木薯干中添加定量铅、砷、汞离子进行实验室模拟酒精发酵,并按照工艺过程设不同点取样检测,总结铅、砷、汞离子在酒精发酵过程迁移规律,并对酒精、废水、废渣中的重金属残留进行安全性评价。添加定量铅、砷、汞对酒精发酵工艺质量没有影响;铅、砷、汞在酒精中未检出,铅、汞主要残留在废渣中,砷在废渣和废水均有残留。
This research is to investigate the degradation and migration rule of Lead,Arsenic and Mercury in the production process of fermentation alcohol and make safety evaluation of the heavy metal residues in alcohol,waste water and dregs.We simulate the alcohol fermentation process in lab by adding quantity of Pb＋,As＋ and Hg＋ into cassavas.Samples are drawn from different sampling points set according to the process and tested.We find that there is no effect on the technology quality of alcohol fermentation.Pb＋,As＋ and Hg＋ haven＇t been detected in alcohol,with most of the Pb＋ and Hg＋ left in the dregs and As＋ in waste water and dregs.
