Influence of papermaking wastewater on the cellulose content of reed

Reed is a kind of better material for papermaking, in which the cellulose content directly affects the value of paper making,and the higher cellulose content is beneficial to the pulping, bleaching, and making the tightness and the transparency paper. A experiment was conducted to test the effect of different irrigation time and wastewater concentration (mg·L-1) of papermaking wastewater on the cellulose content in reed The results showed the cellulose content in reed stems and leaves was the highest when the concentration of wastewater irrigation was 300 mg·L-1, indicating that the cellulose content in reed stems of the germination period was 36.39%(300 mg·L-1)>35.39%(175 mg·L-1)>34.73%(50 mg·L-1)>33.45%(CK).The irrigation wastewater was the most beneficial to cellulose accumulation of reed when reed was during the fast growing period,for example, and the change quantity of the cellulose content in reed stems was 11.75% (rapid growth period) > 9.64% (heading) > 9.6% (maturity) > 7.68% (the leaf expansion period) > 3.64% (germination) when the wastewater concentration was 300 mg·L-1. The cellulose content in reed stems was higher than that in leaves, and they were 33.45% in stem and 22.11% in leaves when the wastewater concentration was 300 mg·L-1 in the germination period. The concentration(X) had the significant effect on the cellulose content of reed(Y),which would be described as equation:Y=0.01X+31.261%。
