三种微藻与苯酚的相互作用研究

Study on Interactions between Three Kinds of Microalgae and Phenol

[目的]研究小球藻、螺旋藻和斜生栅藻3种微藻与苯酚的相互作用。[方法]以小球藻、螺旋藻和斜生栅藻为藻种,人工模拟配置不同浓度苯酚的废水为受试水样,进行微藻与苯酚的相互作用研究。[结果]苯酚对小球藻的生长具有促进作用,而对螺旋藻和斜生栅藻均有一定的抑制作用,其中螺旋藻表现得更为敏感,当苯酚浓度高于200 mg/L时,螺旋藻死亡;小球藻、斜生栅藻对低浓度苯酚均有一定的去除能力,并随苯酚浓度增加其去除苯酚能力减弱。[结论]利用微藻处理低浓度含酚废水具有一定的应用价值。

[Objective] The research aimed to study the interactions between Chlorella sp.,Spirulina sp.and Scenedesmus obliqnus three kinds of Microalgae and phenol.[Method] Chlorella sp.,Spirulina sp.and Scenedesmus obliqnus were used to research on the interaction between microalgae and phenol in simulation wastewater containing various concentrations of phenol.[Result] Phenol promoted the growth of Chlorella sp.However,the phenol had an inhibitory effect to Spirulina sp.and Scenedesmus obliqnus.Among the tested algae species,Spirulina sp.had the lowest resistant ability to phenol.Spirulina sp.died in the tested waste water containing phenol with more than 200 mg/L.Both Chlorella sp.and Scenedesmus obliqnus had some remove abilities to phenol,but removal rate decreased with the increase of phenol concentration.[Conclusion] Dealing with low concentration of phenol wastewater with microalgae has certain application value.
