丙酸发酵废液中丙/乙酸的分离工艺研究

Research on Separation Technique of By-product Propionic acid/Acetic acid from VB_(12) Propionic acid Fermentation Liquor

丙酸发酵生产中产生的大量废液中含有丙酸、乙酸2种有用物质。将废液直接排放不仅对环境造成污染,同时也对资源造成浪费。需要对废液进行资源化处理,寻找合理、有效利用废液,回收其中有用组分的方法,达到减少资源的浪费、提高企业经济效益、减轻有机酸对环境造成危害的目的。

The massive waste liquid was produced in propionic acid fementation process in which included propionic acid and ethanoic acid. Directly discharging the waste liquid not only causes the pollution to the environment, but also simultaneously creats waste to the resources. To resource treat the waste liquid,to seek the method for effectively and reasonably using waste liquid and recycling useful component in order to reduce resources waste, enhance the en-terprise economic efficiency, reduce the organic acid＇s harm to environment.
