水葫芦茎处理含苯酚废水研究

A Study of the Treatment of Wastewater Containing Phenol by Water Hyacinth Stems

比较了干制和新鲜水葫芦茎处理含苯酚废水的能力,探讨了水葫芦茎的用量和重复回收利用对含苯酚废水的处理效果.结果显示:干制水葫芦茎处理苯酚的效果优于新鲜水葫芦茎;300 mL含苯酚浓度为42.2 mg/L的废水,0.5 g干制水葫芦茎对其有最好的处理效果,去除率可达98.6%;已吸附苯酚的水葫芦茎经处理后可重复使用,但处理苯酚的效果逐渐减弱.

A comparison of the capacity of dried and fresh water hyacinth stems to treat phenol-containing wastewater was made and the amount of water hyacinth stems required and effect of treating phenol-containing wastewater with repeatedly recycled water hyacinth stems were explored. The results showed dried water hyacinth stems were better than fresh water hyacinth stems; 0.5g dried water hyacinth stems had the optimal effect for treating 300 mL wastewater containing phenol with a concentration of 42.2 mg/L and the removal rate reached 98.6%; the water hyacinth stems that had adsorbed phenol could be reused, but the effect gradually weakened.
