【摘要】 从处理石油化工废水的活性污泥和长期被对苯二甲酸粉尘污染的土壤中分离筛选出261株好氧细菌,其中部份菌株能降解醋酸、乙二醇,对苯二甲酸、甲醇、苯酚,苯乙烯和丙酮。对降解前4种有机物的最适宜条件,各选一代表菌株进行了探究,结果表明,所试菌株能分别在4,10及14h内将甲醇(50mg/l)、醋酸(2500mg/l),对苯二甲酸(200mg/l)100％降解,而乙二醇(200mg/l)在18h也能降解70％以上。使用混合菌株对石油化工废水进行(处理5L发酵罐)运转试验,也取得了较好的效果。更多还原

【Abstract】 Two hundred and sixty-one aerobic bacteria strains were isolated from the activated sludge for petroleum chemical wastewater treatment and from the soil polluted by terephthalic acid. Some of the strains could degrade acetic acid,ethylene glycol, terephthalic acid, methanol, phenol, styrene and acetone. The optimal conditions for the degradation were studied using one strain for each of the first four compounds mentioned above. It was found that methanol 50mg/l, acetic acid 2500mg/l and terephthalic acid 200mg/l could be degraded completely within 4,10 and 14 hours respectively; ethy-lene glycol 200mg/l could be degraded 70% withinh 18 hours. Good results were also obtained by mixe’d cultures inoculated with petrochemical waste-water in a 5 liter fermenter.更多还原
