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. |
