| 摘 要： | 用海泡石吸附法处理采油废水，考察了处理时间、海泡石加入量和采油废水pH对采油废水COD去除率的影响，并通过正交实验优化了采油废水处理工艺条件。通过正交实验得到的采油废水处理最佳工艺条件为：处理时间6h，粒径为150μm的海泡石加入量200g／L，采油废水pH9。在该条件下处理采油废水，COD去除率达到91％，处理后出水的COD为34．71mg／L，小于GB8978-1996（（污水综合排放标准》中的一级标准（60mg／L）。

| Abstract: | Oil extraction wastewater was treated by adsorption process using meerschaum.The effects of treatment time,meerschaum dosage and wastewater pH on COD removal rate were studied.The process conditions were optimized by orthogonal tests.Under the optimum conditions of treating time 6 h,meerschaum dosage 200 g/L and wastewater pH 9,the removal rate of COD is 91%,the effluent COD is 34.71 mg/L,which is less than the first grade(60 mg/L)of national standards GB8978- 1996. |
