摘　　要：高得率制浆废液具有组成比较复杂,色度高,化学需氧量高等特点.采用超滤分级方法初步考察杨木APMP制浆废液中污染物质的相对分子质量分布,并且采用GC-MS联用仪研究了废液中小分子有机污染物的组成.结果表明:相对分子质量较大的污染物是废液色度的主要来源,实际应用中,超滤技术可以有效地去除这些大分子发色物质;GC-MS检测到废液中的小分子有机污染物主要是脂肪酸类物质,约占检测物质的57.13%,树脂酸的含量很少.The high yield pulping effluent is composed of more complex, high color, high chemical oxygen demand. The molecular weight distribution of contamination of APMP pulping effluent was discussed through using ultrafiltration classification,and the composition of small-sized organic pollutants was also studied by using GC-MS. The results showed that larger molecular weight of pollutants in the effluent were the main source of color, in practical application, ultrafiltration can be an effectively method to remove these colored pollutants. The small-sized organic pollutants which detected by GC-MS were mainly contained fatty acids, accounting for about 57.13 %, but only few resin acid.
