摘　　要：选用ＰＳＡ膜和ＣＡ－ＣＴＡ膜对谷氨散发酵废液反渗透浓缩的工艺条件进行研究，操作压力选在４～８兆帕之间，进料速度选８～１２毫升／秒。用这两种膜浓缩等电点后的废液，经济效益更明显，通量分别是１．４毫升／厘米￣２·时和０．８４毫升／厘米￣２·时，截留率分别达到８６．９％和９９．０％，浓缩液的谷氨酸含量分别为３５．０７毫克／毫升和５０．７３毫克／毫升，浓缩倍数分别可达４．４倍和６．３倍。It is studied to concentrate glutamic acid waste by reverse osmosis with PSAand CA-CTA membrenes.The results was shown,it is more suitble to concentrate glutamicacid waste by reverse osmosis than to do glutamic acid broth.Its operation pressure should be4～8MPa,and feeding speed should be 8～12ml/sec,The penetration flux of PSA and CA-CTA membrenes respectively were 1.4ml/cm￣2·hr and 0.64ml/cm￣2·hr,and the retentionratio,86.9%and 99.0%。 Their glutamic acid contents in the concentrated liquid respectivelywere 35. 07mg/ml and 50.73mg/ml and concentrating multiple of glutamic acid in it were4.4 and 6.3。
