Abstract

The treatment of coal gasification wastewater is difficult because of its complex composition and many contaminants with high concentrations

such as oils

phenols and NH3-N. In this paper

the compositions and characteristics of the wastewater from coal gasification were analyzed and the feasibility of recent technologies for the deep treatment and reclamation of it were reviewed. Aiming to overcome the shortcomings of different technologies and to obtain high water recovery

the feasibility of multi-membrane technologies (ultrafiltration

nanofiltration

reverse osmosis

electrodialysis) for treating it deeply was specially discussed. At last

an outlook on the development trends of the technologies for the deep treatment and reclamation of coal gasification wastewater was given.
