摘要： 针对污染地表水的特点,从辽河油田受石油污染的缓流河床底泥中筛选出一株能有效去除CODCr的微球菌(Micrococcussp.N3-9P),并对其进行了化学包埋法固定化.通过实验,确定了改进的聚乙烯醇-海藻酸钠共固定工艺配方(质量分数)聚乙烯醇10.5%,海藻酸钠0.5%,活性碳3%及微量生长素,优化了过程控制参数.地表水修复实验表明,96h后固定化颗粒对污染地表水中CODCr的去除率为70.9%,明显高于游离菌的33.6%.

Abstract: According to the characteristics of contaminated surface water, a strain of Micrococcus sp. that could remove CODCr efficiently was picked out from the slowly flowing oil-polluted riverbed sludge in Liaohe Oil Field, and then it was immobilized by chemical embedding technique. Through the conditional tests of immobilizing parameters, an improved co-immobilization technique with PVA and sodium alginate was determined, and the immobilizing gel was made of 10.5% PVA, 0.5%Na·Alg, 3% activated carbon and traces of auxin. Experimental results showed that the Micrococcus sp. immobilized in such a way has the ability to remove 70.9% CODCr in contaminated surface water after 96 hours, i.e., 33.6% higher than the removal rate by free thalli.
