摘要
对四种炼油污水分别在碱性和酸性条件下用二氯甲烷萃取；
The extraction of organic constituents in four kinds of refinery waste water with CH2Cl2 was conducted in alkalic and acidic conditions, respectively. Then these extract phases concentrated were analyzed with GC/MS method. The results show that main organic compounds are phenols which occupy 97. 53%, 92. 95% and 90. 94% in delayed coking, catalytic cracking, and air & decompression distillation process waste water, respectively ; while paraffins take 91. 65% in hydrogenation process waste water.
