摘　　要：为了分离出可降低石化工业园污水化学需氧量(COD)的耐盐微生物,利用平板稀释法和划线法分离、纯化出目标菌株,再用革兰氏染色法及生理生化试验对得到的菌株进行鉴定,最后对目标菌株降低COD的能力进行验证。In order to isolate the salt-tolerant microorganisms that can reduce the COD of the wastewater in petrochemical industrial parks,the target strains are isolated and purified by plate dilution method and scribing method,and then the strains obtained by Gram staining and physiological and biochemical tests are used. Identification was carried out,and finally the ability of the target strain to reduce COD was verified.

关 键 词：石油污染 高盐污水 化学需氧量 菌种筛选 生理生化鉴定
