针对污染地表水的特点,从河水底泥中筛选出一株能有效去除CODCr的黄杆菌(Flavobacterium sp.)进行固定化.通过几种固定化工艺的比较,确定了采用改进的PVA-Na.Alg共固定工艺,确定了聚乙烯醇(PVA)10.5%,海藻酸钠(Na.Alg)0.5%,活性炭3%及微量生长素的凝胶剂组成.运行78h的测试结果表明,固定化颗粒对污染地表水中CODCr的去除率为86.27%,明显高于游离菌对CODCr的去除率59.65%.
Immobilization Process of Flavobacterium sp. for Bioremediation of Contaminated Surface Water
According to the characteristics of contaminated surface water, a strain of Flavobacterium sp. that could remove CODcr efficiently was picked out from river substrate sludge and then immobilized. Comparing several immobilization processed, an efficient kind of carrier was found, i.e., a gel made up of 10.5% PVA, 0.5% Na.Alg, 3% activated carbon and microdose of auxin. The results showed that the immobilized Flavobacterium sp. can remove 86.27% CODcr from contaminated surface water in 78 hours, much higher than the 59.65% removal rate by free ones.
