| Abstract: | The study in this paper was made on the disposal technique forwaste drilling fluid,which contained very high chemical oxygen demand(CODcr).A new method of two-step separation technique,chemical destabilization/centrifuge and flocculation/sedimentation,was proposed and used in treating the fluid.The result showed that absorption-bridging was the main process for the destabilization/flocculation.Next,the best chemical agents,those had good flocculation efficiency,were screened out.The result showed that the contents of heavy metal salts,SS and organic matters(COD,oil)of the wastewater resulted from the two-step separation treatment fitted to the standard of GB8978-1996.Especially the remove rate of COD was very high.COD reduced form 9960.2 mg.l-1 to 150 mg.l-1 lower. |
