The process of microwave flocculation and Fe/C micro-electrolysis was used to treat several oilfield production wastewater, and the effects of microwave on flocculation, disinfection, de-oiling and decrease of the corrosion rate were investigated.The results showed that microwave coagulation could reduce 20% dosage for PAC and 30% for PAM, and the settling time of microwave flocculation was only 1/4 of normal flocculation, and total removal efficiency of COD for the wastewater reached 96%.Microwave could effectively kill total growth bacteria (TGB) and sulfate-reducing bacteria (SRB) in the wastewater, and the removal of bacteria reached 99%.Microwave accelerated oil-water separation and promoted emulsion-breaking simutaneously, and the average removal efficiency of oil was 95%.Microwave also played an active role in the reduction of corrosion rate, and the average corrosion reduction reached 90% in the microwave assisted process, which was 10 points higher than that in normal process. 相似文献

进行了微波辅助工艺处理油田酸化压裂废水的应用研究,考察了微波絮凝与氧化工艺对酸化压裂废水的色度、COD、SS、含油量和细菌的去除效果及其对废水腐蚀率的降低作用,并进行了同等条件下的常温对照实验.与常温絮凝相比,微波絮凝工艺中絮凝剂PAC和PAM的用量减少了200mg/L和2.5mg/L,絮凝沉降时间仅为常温絮凝的1/4,可是废水的COD去除效果却好于常温絮凝.微波工艺处理后,酸化压裂废水的含油量去除率为96%、废水中硫酸盐还原菌和腐生菌的死亡率达98%以上,废水腐蚀率由4.2mm/a降至0.049mm/a,废水可生化性得到了提高.实验结果表明,微波工艺对油田酸化压裂废水具有很好的处理效果. 相似文献
