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.
