摘　　要：富硒米曲霉发酵产生的废液目前尚无现成的处理工艺或方法套用,为此考察了铁硒共沉淀法的除硒效果。结果表明,发酵废液pH值控制在5.5~6.5;氯化铁（FeCl3.6H2O）的投加量5 g/L;搅拌时间15 min;静置30 min;高速离心20 min（3000 r/min）;出水硒含量达到硒排放一级标准。As there are no recorded treatment methods for waste liquor produced by fermentation of Selenium-riched Aspergillus Oryzae, this paper makes an attempt to remove Selenium from waste liq- uor with Fe/Se co-precipitation and tests its effectiveness. The results show that the content of Sele- nium in waste water reached the first-class national discharge standard of Selenium when pH values of waste liquor were controlled between 5.5 and 6.5, FeCl3 · 6H2O was put with the criterion of 5 g/L, the mixed liquor was stirred for 15 minutes, set still for 30 minutes and centrifuged for 20 minutes （3000 r/rain）.
