摘要:通过气相色谱/质谱联用仪(GC/MS)、高效液相色谱/质谱联用仪(HPLC/MS)等方法系统测定了桉木化机浆制浆废水成分,并进行了定性和定量分析。结果表明,桉木化机浆制浆废水中含有大量木质素、半纤维素、有机物、糖类等,其中木质素含量较高,为73 g/L,是杨木化机浆制浆废水的1.2倍;有机污染物40多种;桉木化机浆制浆废水中还检测出多种糖类,是后续厌氧处理的基本条件。 |
Abstract:The components of eucalyptus chemi-mechanical pulping wastewater were systematically determined by GC/MS, HPLC/MS and other methods with qualitative and quantitative analysis. The results showed that eucalyptus chemi-mechanical pulping wastewater contained a large amount of lignin, hemicellulose, organic matter, sugar, etc. The high content of lignin reached 73 g/L, which was 1.2 times that of poplars chemi-mechanical pulping wastewater. Moreover, the types of organic pollutants were more than 40. A variety of sugar was also detected in the eucalyptus chemi-mechanical pulping wastewater, which was the basic condition for subsequent anaerobic treatment. |
