| 摘 要： | 采用介质阻挡放电等离子体技术去除太湖水华蓝藻,考察了放电输出功率、空气流速、添加剂(异丙醇、腐植酸)等对蓝藻去除的影响。结果表明,介质阻挡放电能去除太湖水华蓝藻,放电功率100 W,空气流速1.0 L/min,放电18min,在光照强度2 000 lx和25℃下培养4 d,初始叶绿素a浓度为9.58 mg/L藻液中蓝藻去除率达87.8%。增加放电输出功率和空气流速能提高蓝藻的去除效率;腐植酸促进了介质阻挡放电对蓝藻的去除;而异丙醇添加剂抑制了介质阻挡放电的作用。放电处理后,蓝藻细胞内类胡萝卜素含量、SOD活性、MDA含量发生明显变化,介质阻挡放电破坏了蓝藻细胞内含物。 |

| Abstract: | In this study,non-thermal plasma produced by dielectric barrer discharge(DBD) was employed to remove the water bloom cyanobacteria in Taihu Lake.The effects of discharge power,air flow rate,various additives(2-propanol and humic acid) on the removal efficiency of cyanobacteria were discussed.The result showed that the cyanobacteria could be removed by DBD.With 100 W of discharge power,1.0 L/min of air flow rate,18 min of discharge time,2 000 lx of light intensity and 4 d of culture time at 25℃,the removal efficiency over 87.8%(the initial Chl-a concentration of cyanobacteria was 9.58 mg/L).The removal efficiency increased with the increasing of discharge power and air flow rate.The presences of humic acid enhanced the cyanobacterial removal,while the addition of 2-propanol inhibited the cyanobacterial removal.The concentrations of carotenoids and malondialdehyde,the activity of superoxide dismutase in cyanobacterial cell changed after treatment,the intracellular materials of cyanobacteria were damaged. |
