摘　　要：从冀东油田钻井现场采集的受钻井废水污染的土壤样品中筛选到 2株酵母菌种 (Wickerhamielladomercqii和Candidaboidinii) .将这 2种酵母菌混合后在 pH4 0的条件下处理钻井废水 ,TOC去除率为 40 5 % ,略高于驯化后的活性污泥在中性条件下的处理效果 (3 5 2 % ) .分子量的切割实验结果表明 ,在分子量为 60 0 0 0以上的有机质中 。Two strains of yeast, namely Wickerhamiella domercqii and Candida boidinii , were acquired through screening from soil samples contaminated by drilling wastewater. A TOC removal of 40.5% was acquired when the mixture of the two yeast strains was used for drilling wastewater treatment, a little higher than that with activated sludge acclimated with wastewater (35 2%). Some organic compounds in the fraction of molecular weight above 60,000 were found to be biodegradable.
