摘　　要：研究了两种丝状绿藻,脆弱刚毛藻(Cladophora fracta)和长形水绵(Spirogyra longata)对水体中低浓度苯酚(≤6mg·mL-1)的去除作用。结果表明,在不考虑交互作用下,脆弱刚毛藻和长形水绵对苯酚的去除率分别为86%和75.63%,脆弱刚毛藻去除苯酚试验中,温度是主要影响因素,长形水绵去除苯酚试验中,处理时间是主要影响因素;在考虑交互作用下,脆弱刚毛藻和长形水绵对苯酚的去除率分别为88.98%和75.63%,脆弱刚毛藻去除苯酚试验中,温度是主要影响因素,长形水绵去除苯酚试验中,处理时间是主要影响因素;脆弱刚毛藻去除苯酚实验中各因素最优水平组合为温度18℃,处理时间2h,藻重0.5g,长形水绵去除苯酚试验中中各因素最优水平组合为温度8℃,处理时间1h,藻重0.5g。Removal effect of two species of filamentous green algae,Cladophora fracta and Spirogyra longata,on phenol at low concentration was studied.The results show that the removal rate of C.fracta and S.longata towards phenol are 86% and 75.63% under absence of between-subjects effects,respectively.It was indicated the temperature is the primary factor to C.fracta and the exposure time is the primary factor to S.longata.The removal rate of C.fracta and S.longata towards phenol were 88.98% and 75.63% under presence of between-subjects effects,respectively.It was indicated the temperature is the primary factor to C.fracta and the exposure time is the primary factor to S.longata.The best combination for removing phenol by C.fracta is temperature 18℃,exposure time 2 h and algal weight 0.5 g and the best combination for removing phenol by S.longata is temperature 8℃,exposure time 1 h and algal weight 0.5 g.
