| 摘 要： | 利用聚乙烯醇-海藻酸钠(PVA-Na.A lg)联合包埋固定化一株黄杆菌O il-56,进行污染地表水修复实验研究,结果表明固定化细菌的修复效果明显好于游离细菌。同时利用扫描电子显微镜观察了固定化颗粒内部细菌形态的变化,解释了由于Na.A lg溶解导致水体CODC r升高的原因,并分析了固定化颗粒传质扩散性能的缺陷,指出PVA-Na.A lg固定化工艺尚需改进。

| Abstract: | The remediation of polluted surface water by immobilized Flavobacterium sp.Oil-56 using PVA-Na·Alg was studied.The results show that the remediation effect of immobilized bacteria is better than that of free cells.The SEM analysis of the particle microstructure showed the morphological changes of the(immobilized) F.Oil-56.The reason of COD_(Cr) rising was mainly caused by Na·Alg dissolving.The results also indicate that PVA-Na·Alg immobilization technology should be improved because of the particle′s transferring and diffusing limitation. |

| Keywords: | PVA-NaAlg immobilization remediation transferring and diffusing polluted surface water |
