doi:10.3863/j.issn.1000-2634.1999.02.23

Abstract

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.

Key words: waste water treatment, acid, coagulation adsorption on active carbon
