摘要: 发酵法生产核黄素会产生大量的结晶母液,很难处理。本文首先采用聚丙烯酰胺对结晶母液进行絮凝沉降处理,确定了最佳投料量200mg/L,最优pH 5~6,母液中的化学需氧量(COD)去除率达60%以上。絮凝沉降物采用喷雾干燥法进行回收,对几个主要参数进行了优化,得到了最佳操作参数:进风温度190℃,进样流速3mL/min,β-环糊精添加量1%,产品得率66.95%,含水率2.9%,有效减小了对环境的影响。

Abstract: The production of riboflavin by fermentation would produce a lot of crystallization mother liquor and it is hard to treat.The crystallization mother liquor was firstly treated by flocculation sedimentation with polyacrylamide in this study.The optimal adding quantity of polyacrylamide and pH were 200mg/L and 5~6,respectively.It can remove over 60% chemical oxygen demand(COD) of crystallization mother liquor.Flocculation was recovered by method of spray drying.The optimal operating parameters as follows:inlet air temperature was 190℃,flow rate of sample was 3mL/min,adding quantity of β-cyclodextrin was 1%.Under the conditions,the product yield and moisture content were 66.95% and 2.9%,decreasing the impact on the environment effectively.

Key words: crystallization mother liquor, polyacrylamide, flocculation, spray drying
