Treatment of solvent-refined coal wastewater
The wastewater selected for study was the SRC-I recycle process water stream after oil-water separation. This stream contains water formed in the coal-liqufaction reactor, water added to the process to prevent ammonium-salt-deposition, and moisture included in the feed coal. The water was condensed concomitant along with the product and thus was in intimate contact with the product steam at elevated temperatures. Water-soluble components present in the liquid product are in this stream. This wastewater is considered to be the most representative sample available of recycle process water to be formed in large-scale SRC-I facilities. This investigation has demonstrated that a combination of dissolved-gas stripping, biochemical oxidation, and activated-carbon adsorption is effective in the treatment of SRC-I process recycle water. 17 references, 3 figures, 5 tables.
