摘要:
利用嗜油菌NY3菌的固定化生物膜处理含油废水．用静态曝气法确定固定化时间、载体量、固定化液初始pH值．确定生物膜处理运行的HRT，并评估生物膜循环使用的可能性．结果表明，载体10 g/L，pH7.5～9.0，固定51 h，膜生物量达488.32 mg/g．其处理含油废水最佳HRT为6 h，出水油量在1.38～3.2 mg/L．废水处理后，将载体置于营养液中培养15 d，膜上NY3菌能将所吸附的油降解，使其恢复活性，并可循环利用．
Abstract:
Treatment of oil-bearing wastewater by using immobilized bio-film of NY3 strain was studied. The immobilization time, the optimum dosage of carrier, and the initial pH of immobilized culture for NY3 strain to be immobilized on surface of polyurethane foam carrier were studied by using static aeration. The optimum HRT was determined. Also the possibility of recycle of the bio-film was studied. The results showed that immobilized bio-film of NY3 strain could quickly form within 51 h under dosage of carrier was 10.0 g/L (culture medium),the initial pH of immobilized culture was 7.5~9. The maximum amount of biomass on bio-film reached 488.32 mg/g. The optimum HRT for treating oil-bearing wastewater is 6 h, and the concentrations of oil in effluent kept in range of 1.38-3.2 mg/L. After treatment, the biofilm collecting into culture medium without oil was incubated 15 d, NY3 strain on the bio-film degraded the adhered petroleum and the bio-film was recovered for recycling.
