Abstract:

With the large-scale development of the oil and gas industry, the environmental problems caused by oily waste water have become increasingly serious, and the air flotation cyclone technology has been widely used as an efficient separation method. In order to further improve the separation effect of this technology, a one-factor experiment was conducted on the microbubble density M, rotational angular velocity, flocculant type and concentration using experimental methods, and the response surface method was used to optimize the combination of several factors. The single factor study found that the optimal conditions are: microbubble density 2.88×104 microbubbles/ml, rotational angular velocity 460 r/min, and the flocculant PAFC had a better separation effect. Response surface method analysis yielded a significant effect of the interaction of X1, X3 with the three variables, and the optimal combinations: 2.47×104 microbubbles/ml for M, 440 r/min for rotational angular velocity, and 40 mg/L for the concentration of flocculant PAFC.

摘要:

随着油气工业的大规模发展,含油污水引发的环境问题日益严重,气浮旋流技术作为一种高效的分离方法得到广泛应用。为了进一步提高该技术的分离效果,利用实验方法对微气泡密度、旋转角速度、絮凝剂种类与浓度进行了单因素实验,利用响应面法对几种因素的组合进行了优化。单因素研究发现最优条件为:微气泡密度2.88×104个/ml、旋转角速度460 r/min,絮凝剂PAFC的分离效果较好。响应面法分析结论是X1X3与3个变量的交互作用影响显著,最优组合:微气泡密度为2.47×104个/ml,旋转角速度为440 r/min,絮凝剂PAFC浓度为40 mg/L。
