摘要
本研究通过包埋固定化微生物法固定除油菌（Y1’菌），用于处理含油废水，并以水体中乳化油去除率为指标考察了影响乳化油降解的各种因素。选用聚乙烯醇（PVA）-海藻酸钠（SA）复配作为包埋固定化载体材料，制备成固定化微生物小球（IMB），通过实验优化了IMB制备的工艺条件。连续批次除油实验结果表明，在25-40℃，固液比1：10，HRT为6h的条件下，进水油含量在20—50mg／L，乳化油去除率可达85％-90％，出水油含量低于5mg／L。
The oil-containing wastewater from oilfield was treated the immobilized microbial cell balls （IMB） and the affecting factors on oil removal rate were studied. The IMB was prepared with polyvinyl alcohol （PVA）-sodium alginate（SA）. The experimental results indicate that the removal rate of emulsified oil in the wastewater was about 85% - 90% under temperature 25 - 40℃ , solid-to-liquid ratio 1：10 and HRT 6 h,oil content in wastewater 20 - 50 mg/L, and the oil content in treated water is below 5 mg/L.
