摘  要：
研究波吉卵囊藻(Oocystis borgei)对Cu2+、Zn2+的吸附动力学及温度、光照度和盐度对Cu2+、Zn2+吸附效果的影响。结果表明,波吉卵囊藻对Cu2+、Zn2+的吸附经历了快速、中速和慢速3个吸附步骤,快速吸附在实验0.5 h内完成,中速吸附在实验8 h内完成,8 h后为慢速吸附。温度为25～30℃时,波吉卵囊藻对Cu2+、Zn2+的吸附量分别为5.61 mg/g、6.92 mg/g。光照度大于或等于3000 lx时,藻细胞对Cu2+有较好的吸附效果;光照度大于或等于2 000 lx时,藻细胞对Zn2+有较好的吸附效果。盐度为25～30时,藻细胞对Cu2+吸附量为5.93 mg/g,盐度为20时,藻细胞对Zn2+吸附量为6.97 mg/g。因此,当温度为30℃,盐度低于25,光照度大于2000 lx时,波吉卵囊藻可以很好的消除对虾养殖水体中重金属离子污染,保持良好的养殖水环境。

摘  要：
The effect of adsorption dynamics,temperature,illumination intensity and salinity on adsorptive performance of Oocystis borgei to Cu2+ and Zn2+was studied.The results showed that there were three adsorbent processes(rapid,intermediate speed and low speed) in the adsorption of Oocystis borgei to Cu2+ and Zn2+.In the experiment,rapid adsorption was completed in 0.5h.Intermediate adsorption was completed in 8h,and then after 8h was low speed of adsorption.Good adsorptive performance was obtained when temperatures ranged from 25 to 30℃,and the best adsorption quantity was 5.61mg/g(Cu2+) and 6.92mg/g(Zn2+).When the illumination intensity was greater than or equal to 3000lx,algae cell showed good adsorptive performance to Cu2+,and while the illumination intensity was greater than or equal to 2000lx,algae cell showed good adsorptive performance to Zn2+.Good adsorptive performance to Cu2+ was obtained when the salinity ranged from 25 to 30,and the best adsorption quantity to Cu2+was 5.93mg/g.When the salinity was 20,algae cell showed good adsorptive performance to Zn2+,and adsorption quantity was 6.97mg/g.Therefore,there was a significant removal quality of heavy metal ion by Oocystis borgei in prawns aquaculture when temperature was 30℃,salinity was less than 25 and illumination intensity was over 2000 lx.
