摘要
Abstract
A novel chemical process is introduced for the treatment of coal-gasification wastewater produced from Lurqi gasification, and the process has been industrially realized. Ammonia and acidic gas in coal-gasification wastewater are removed through a sour water stripping tower in the new process, through which the pH value of the treated wastewater is decreased from 9-11 to 7, and hence it is beneficial to the subsequent solvent extraction for phenols. The distribution coefficients of M1BK to phenol and polyhydric phenols are greater than those of DIPE. The application of MIBK as extraction solvent would recover more phenolic substances from wastewater than DIPE. The COD value would be further reduced before the coal-gasification wastewater flowed into the biochemical treatment.关键词
