【摘要】 伴随原油开采中污水量的不断增加及其排放指标的提高,对含油污水的处理技术提出更高的要求,气浮处理技术以低能耗、效率高等优势成为研究和应用的重点方向。针对气浮污水处理技术的基本理论,分别从微气泡的生成方式、高效旋流气浮的处理工艺和流场特征等方面,结合前期在高效管道式分离技术研究中取得的成果,自主研制新型的高效旋流气浮污水处理技术和装置,并设计加工形成符合工业应用标准的样机。现场测试研究中,对设计加工的样机按照实际工况进行连续运行和测试,得出经处理后水中含油率可以降至10mg/L以内,并分别给出了处理量和絮凝剂添加量等因素对污水处理性能的影响规律。更多还原

【Abstract】 The requirement of wastewater treatment technology is becoming higher as the increasing of water content in oil extraction and its emission targets in oil industry,and the flotation technology is one of the great technologies with the advantages of low energy consumption and high efficiency which can meet the requirement greatly.According to the basic theory of flotation and research consequence of pipe-type oil-water separator,the micro-bubble generated technology,flotation process and its flow field characteristics are investigated to design a new-type flotation technology with independent intellectual property rights.In the study,the methods of field test in oil production were used to obtain the flow field characteristics and processing capacity of the new-type flotation equipment.In the results,the flotation was operated for a long time and the oil volume fraction in wastewater can be decreased to less than 10mg/L which is greater than the requirement of environment.Also,the effect of flocculating agent and the capacity of flotation equipment were studied respectively.更多还原
