【摘要】 本文对凤眼莲与喜旱莲子草对废纸再生纸浆废水的净化效果作了初步探讨。实验表明,水生植物凤眼莲与喜旱莲子草对废水CODcr具较好的净化效果,且能有效地增加废水溶解氧,但对色度和木质素去除不明显。此外,废水中的硫化物对该两种水生植物具较强的毒性。更多还原

【Abstract】 The purificating capabilities of Eichhornia crasspes and Alternanthera phi-oxenoidcs in wastewater treatment of paper pulping were studied. The experimental resuHs showed that these two aquatic plants can decrease CODcr quite efficiently and increase DO of the wastewater. However, they are not suitable to use to remove the colour and iignin from the wastewater.In additinn- they are very sensitive to suifide in the wastewater更多还原
