| 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２００ｍｇ／Ｌ以下，达到排放标准。

| Abstract: | n 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. |
