Recovery Analysis of papermaking wastewater from the pretreated Eucalyptus camaldulensis Wood Chips
Wood extractive brings more difficulties on the treatment of polluting wastewater from wood industry and paper mill, Therefore, many enterprises have to raise pretreated procedure of wood chips of papermaking to decrease the disadvantageous impacts from wood extractive. However, wastewater from wood chip pretreatment becomes a difficult and urgent issue. Eucalyptus camaldulensis has been widely planted in South China and mainly used as wood chips of papermaking. In order to better recover and utilize the pretreatment wastewater of E. camaldulensis wood chip and hence decrease its pollution to water and land environment, the chemical components of cold water extractive of E. camaldulensis wood chip was analyzed by pyrolysis-GC/MS after enriched and dissolved in benzene-methanol. Relative content of each component was determined by area normalization, and 32 compounds representing 99.53％ of the extractive were identified. The main constituents were as: benzene,methyl (1-methylethyl)-(35.41％), ethanol,2-butoxy-(8.73％), (-)-globulol (6.76％), 1Hcycloprop eazulene,decahydro-1,1,7-trimethyl-4-methylene-,1aR-(1a.alpha.,4a.alpha.,7.alpha.,7a.beta.,7b. alpha.)-(6.14％), etc. As the first report here, the results by pyrolysis-GC/MS and function analyses showed that most chemical components of cold water extractive of E. camaldulensis wood chips can be developed into top valueadded materials of medicine, cosmetic, food, solvent and bioactive chemical industry.
