摘要： 针对含油废水的特点,从盘锦某沥青厂被稠油污染的土壤和该厂含油废水生化处理单元的活性污泥中,经过筛选、驯化实验,获得TA-11,TA-17,HA-9,HD-1共4株对油类物质具有高效降解去除能力的细菌.对筛选出的4株菌进行了含油废水处理实验,4株菌均在pH为7.0、温度为30℃时去除率达到最高值,运行64 h后单一菌株CODcr的去除率最高可达68%;混合菌株对含油废水中CODcr的去除率明显高于单一菌种.

Abstract: According to the characteristics of oil contaminated wastewater, four strains of microorganism, named TA-11, TA-17, HA-9 and HD-1, which can degrade oil and CODCr in oil contaminated wastewater, were picked out through screening/domestication from the oil contaminated soil and activated sludge in the wastewater treatment system of a pitch plant in Panjin, China. Experimental results showed that any of the four strains of microorganism can remove oil and CODCr from the oil contaminated wastewater effectively with a highest removal rate of CODCr up to 68% at 30°C and pH value 7.0 if treated for 64 h. And it was revealed that the removal rate of CODCr from oil contaminated wastewater is much higher by mixed bacilli than by single bacillus.
