| 摘 要： | 根据钻井废水的污染特征和目前处理中存在的问题,提出了“酸化中和—混凝—活性炭吸附”三步处理的方法,并对其可行性进行了实验研究。结果表明,酸化中和阶段,可将废水中的悬浮物去除80%以上,CODCr去除50%;混凝后CODCr去除率达到75%;最后,采用活性炭吸附进行深度处理,可使CODCr值下降为200 mg/L以下,达到排放标准。

| Abstract: | An acid neutralization-coagulation-adsorption on activated carbon trio-step method has been presented and investigated on the basis of characteristics of drilling waste water and present problems. Results have indicated that over 80% suspended solid and 50% CODCr can be removed in the first step,75% CODCr can be removed after coagulation, and the CODCr value can be reduced to 200mg/L below by using activated carbon for further process, which has reached the exhaust criteria. |

| Keywords: | waste water treatment acid coagulation adsorption on active carbon |
