菹草和豆瓣菜去除水体中低浓度苯酚的研究①

摘要

Removal effect of low concentration phenol in water by two aquatic plants,Potamogeton crispus and Nasturium officinale,was conducted.The results show that the removal rates of P.crispus and N.officinale on phenol were 78.69% and 82.86%,respectively.The best combination of removing phenol by P.crispus was temperature 8℃,exposure time 2h and weight 0.5 g and temperature 28 ℃,exposure time 2h and weight 0.5g by N.officinale.%研究了两种水生植物，菹草Potamogeton crispus和豆瓣菜Nasturium officinale对水体中低浓度苯酚(≤6 mg/L)的去除作用。结果表明菹草和豆瓣菜对苯酚的去除率分别为78.69%和82.86%，菹草对苯酚去除的最优水平因素组合为8℃，2 h，0.5 g，豆瓣菜对苯酚去除的最优水平因素组合为28℃，2 h，0.5 g。两种植物对水体中低浓度苯酚具有良好的耐受性和明显的净化效果，具有处理含酚废水的潜力。
