摘要： 钻井废水来源于油气田勘探开发作业过程，含有种类繁多的有机类钻井液添加剂和石油类污染物。利用城市污水处理厂活性污泥好氧生化处理钻井废水，通过刚定微生物生化呼吸速率曲线考察废水的可生化性，研究了微生物营养、微生物浓度、活性污泥的驯化对可生化性的影响。结果表明，钻井废水具有可生化性，钻井废水中的污染物质时驯化后的活性污泥是易降解的。

Abstract: Drilling wastewater contains various organic additives and oil contaminants produced by the process of oil -gas exploration and development operation. By the technique of aerobic biologi cal treatment，we use the activated sludge taken from the munic-ipal sewage plant to disposal drilling wastewater, and investigate the biodegradation feasibility by determination the curves of bio-logical respiration rate. Some factors such as microorganism nutrition, Mixed Liquor Suspended Solid(MLSS) and acclimation of activated sludge have been studied to analysis the influence of biodegradation. Results show that biodegradation is feasible for drilling wastewater, and the acclimatized activated sludge has more efficiency.
Key words: drilling wastewater, activated sludge, aerobic biological oxidation, biochemical respiration, biodegradation feasibility
