摘　　要：针对传统的微电解试验在压裂液处理中效率不高的问题,以延长油田1#压裂返排液作为研究对象,结合压裂返排液处理特点,提出一种新型的联合处理工艺,即空化撞击流结合微电解--Fenton氧化处理。分别通过空化撞击流技术+铁碳微电解试验、Fenton氧化正交实验探讨不同考察因素对COD_(Cr)去除率的效果。通过该联合工艺,压裂返排液中COD_(Cr)去除率达到93%。试验证明与传统的微电解法-Fenton氧化相比,空气流技术可有效的促进微电解反应,并为后续的Fenton氧化奠定了基础,减少了Fenton氧化成本。The traditional micro electrolysis method has low efficiency in the treatment of fracturing waste fluid. In this paper, taking oilfield 1# fracturing waste fluid as a research object, combined with the fracturing waste fluid treating characteristics, a new combined process was put forward, cavitation impingement flow- micro electrolysis-Fenton oxidation treatment. Effect of different factors on the removal rate of CODCr was investigated by the orthogonal experiment. Through using the combined process, CODCr removal rate of the waste fracturing fluid can reach to 93%. Experiments show that, compared with the traditional micro electro oxidation method-Fenton oxidation, air flow technology can effectively promote the micro electrolysis reaction, and lay the foundation for the subsequent Fenton oxidation, reducing the cost of Fenton oxidation.
