| 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（Wickerhamiella domercqii和Candida boidinii）。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（35．2％）。分子量的切割实验结果表明,在分子量为60000以上的有机质中,也有部分有机质具有生物可降解性。 |

| Abstract: | 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. |
