针对传统型Fe-C微电解反应器(1#)易堵塞、易短流的缺点,设计了改进型仓氏微电解反应器(2#),并比较了两种装置对胜利油田某采油厂废水的处理效果。结果表明,在pH值为4、进水流速为0.2 m/s、反应区高度为40 cm、进水COD值为480 mg/L的条件下,2#和1#最佳反应时间分别为30 min和60 min,COD去除率分别为86%和70%,浊度去除率分别为98.4%和94%。可见2#反应器通过流态改善,增大了废水与电解质材料的接触面积,缩短了水力停留时间,提高了COD和浊度的去除率。某油田的中试结果表明,2#微电解处理对高浓措施废液悬浮物、黏度、总铁、总硬度平均去除率分别为38.78%~42.31%、12.54%~32.38%、69.23%~71.17%和37.29%~61.76%,较改进前均有较大改善,处理后水质达到该油田采出水回注技术指标要求。(Aiming at the shortcoming of traditional Fe-C micro-electrolysis reactor(1#), which was easy to be blocked and short-circuiting current, an improved honeycombed micro-electrolysis reactor(2#) was designed. The effects of two kinds of reactors on the treatment of wastewater from an oil production plant in Shengli Oilfield were compared. The results showed that: Under the conditions of pH 4, inlet velocity 0.2 m/s, reaction height 40cm, and influent COD 480 mg/L, the 2# and 1# reactors’ reaction time were 30 min and 60 min, the removal rate of COD were 86% and 70%, and the turbidity removal rate were 98.4% and 94% respectively, it can be seen that the improved flow state of 2# reactor increased the contact area between wastewater and electrolytes, reduced the hydraulic retention time, and improved the removal rate of COD and turbidity. The pilot-scale application results in Changqing oilfield showed that the average removal rate of suspension, viscosity, total iron and total hardness in 2# reactor for different concentration wastewaters were 38.78%-42.31%, 12.54 % -32.38 %, 69.23 %-71.17 % and 37.29 %-61.76 % respectively, which were greatly improved compared with 1#, and the treated water can meet with the requirements of oilfield produced water reinjection technology indexs.)
