摘　　要：为经济、高效地处理船舶压载水中的微藻,采用铁碳微电解技术对含塔胞藻和赤潮异弯藻的藻液进行处理.考察铁屑和活性炭总投加量、铁屑与活性炭质量比、铁屑和活性炭粒径、搅拌转速和反应时间等因素对处理效果的影响.结果表明:当铁屑和活性炭总投加量为12 g/L,铁屑与活性炭的质量比为1∶1,铁屑粒径为[0.15,0.90)mm,活性炭粒径为(0,0.15)mm,转速为160 r/min,反应时间为75 min时,塔胞藻的去除率可达到98.34%;当铁屑和活性炭总投加量为12 g/L,铁屑与活性炭质量比为1∶1,铁屑和活性炭粒径均为(0,0.15)mm,转速为140 r/min,反应时间为60 min时,赤潮异弯藻的去除率可达到99.61%.To treat the microalgae in ship＇ s ballast water economically and effectively, the water that contains Pyramimonas sp. and Heterosigma akashiwo is treated by the iron-carbon micro-electrolysis tech- nique. The factors influencing the treatment efficiency are considered where the factors include the iron and active carbon dosage, iron to active carbon mass ratio, iron and active carbon particle sizes, blender＇ s rotational speed, and reaction time. The result shows that Pyramimonas sp. removal rate can reach 98.34% under the condition of the iron and active carbon dosage 12 g/L, the mass ratio of iron to active carbon 1： 1, the iron particle size [0.15,0.90）mm, the active carbon particle size less than 0.15 mm, the rotational speed 160 r/min and the reaction time 75min; Heterosigma akashiwo removal rate can reach 99.61% under the condition of the iron and active carbon dosage 12 g/L, the mass ratio of iron to active carbon 1： 1, both the iron and active carbon particle size less than 0.15 mm, the rotational speed 140 r/min and the reaction time 60 min.
