| 摘 要： | 钻井废水用硫酸铝类净水剂混凝处理后，ＣＯＤ值常不能达标。用ＣａＯ配合净水剂处理钻井废水，在净水剂用量不变以至减少的情况下，在室内和现场都获得了２４小时澄清比上升、净化水ＣＯＤ值下降的良好结果。此方法已在川东钻探公司的井队推广使用。

| Abstract: | At drilling sites of the named Company the abandoned drilling mud is diluted properly with water and treated by Al_2(SO_4)_3-based coagulant (or plus a coagulant aim). Often the COD values of the purified waste water are still high. By using coagulant/limie combination the COD values are lowered by 10-60 mg/1 while the use level of the coagulant may be decreased.This way of waste water treating has been put into wide use at drilling sites in East Sichuan. |
