摘要
针对丝绸精炼废水中含有大量溶解性丝胶蛋白质,利用其两性特点,经过酸析提取粗丝胶蛋白质,并对丝绸精炼废水进行预处理;对酸析上清液利用超滤膜分离技术进一步浓缩丝胶蛋白质及废水处理.结果表明,在最佳条件下酸析CODcr去除率在35%以上,超滤CODcr去除率在70%左右,从最终结果看,经过酸析和超滤处理以后的出水还不能达到排放要求,还需进一步生物处理.
In the light of much dissolved sericin protein was contained in the silk washing waster water and its amphiprotic, the sericin protein can be extracted by acid protein.Then the supernatant of acid protein were (further) concentrated by super-filtration. The results indicated that the deducted efficiency of CODcr were (exceed) 35% in acid protein and about 70% by super-filtration under the optimum conditions, respectively. (The) disposed water cannot reach the outlet qualitative standard after acid protein and super-filtration, so (further) bio-treatment was required.
