摘要
研究了应用聚乙烯醇(PVA)将除油菌群固定于核桃壳粒上的固定化方法的除油效果。结果表明,复合载体具有较高的除油效能,除油率分别达到65.58%(36h),84.85%(48h),90.03%(60h)。与直接吸附方法相比,该法在保持细菌活性、抗水质变化冲击方面优势显著。
Degreasing effect of bacterial strains immobilized on particles of walnut shell by polyvinyl alcohol （PVA） was researched in this paper. It was showed that the multiplex carrier had a good performance, removal oil rate was 60.58%（36 h）, 84.85%（48 h）, 90.03%（60 h）respectively. The comparative study demonstrated that this method was better than directly adsorptive method at keeping activity of bacteria and enduring the change of water quality.
